Import From Excel To SQL Server - Can It Be More Efficient ?

Oct 21, 2004

Hello All,

Iam new to the world of ASP .Net. Right now iam building an application that will IMPORT about 5,000 records from an Excel spreadsheet to a table in MS SQL Server. Right now the code works correctly, but i feel it is not efficient and takes a little bit of more time in doing the import. Could you guys throw some light on how i can make the code run more faster ? Someone suggested me that i can use DataAdapter and update the table in the database thru an update method available with it. I dont know how to do it? Could anyone share with me a snippet of code that does this ?

Here is my code:

Private Sub ProcessRecords()
Dim ds2 As New DataSet
' readExcelSheet is a user-defined function that reads a spreadsheet and returns a DataSet object
ds2 = readExcelSheet("C:InetpubwwwrootProject1Book2.xls", "SELECT * FROM [Sheet1$]")
Dim myConnection As SqlConnection = Connection() ' user-defined function that returns a SQLConnection object
myConnection.Open()
Dim strSQL As String = "insert_member" ' stored procedure that inserts records
Dim myCommand As New SqlCommand(strSQL, myConnection)
myCommand.CommandType = CommandType.StoredProcedure
myCommand.Parameters.Add("@salutation", SqlDbType.NVarChar)
myCommand.Parameters.Add("@firstname", SqlDbType.NVarChar)
myCommand.Parameters.Add("@lastname", SqlDbType.NVarChar)
myCommand.Parameters.Add("@company", SqlDbType.NVarChar)

Dim i, j As Integer
Response.Write(Date.Now() & "<br>")
For i = 0 To ds2.Tables("Members").Rows.Count() - 1
myCommand.Parameters("@salutation").Value = ds2.Tables("Members").Rows(i).Item("sal")
myCommand.Parameters("@firstname").Value = ds2.Tables("Members").Rows(i).Item("firstname")
myCommand.Parameters("@lastname").Value = ds2.Tables("Members").Rows(i).Item("lastname")
myCommand.Parameters("@company").Value = ds2.Tables("Members").Rows(i).Item("company")
j = myCommand.ExecuteNonQuery()
If (j > 0) Then
Response.Write("Record Inserted - " & i + 1 & "<br>")
End If
Next
Response.Write(Date.Now() & "<br>")
myConnection.Close()
End Sub

Please reply soon.
Thank You.

SQL Server 2012 :: Efficient Way To Insert From Foreign Key Lookups

Feb 17, 2015

An SSIS task imports data from a flat file and inserts the data into a staging table. The staging table holds the data in its raw form. A second process then selects the data from the staging table, looking up the foreign key id's for raw data values, and then inserts the data into the live table.

SQL - Only key columns shown for clarity
-- Staging Table
CREATE TABLE Staging
(Information VARCHAR(10),
MachineName VARCHAR(10),
Status VARCHAR(10))

[code]...

The insert into the live table should look up the id for machine 1, and the id of status success and insert the foreign key values into the live table for the row.There could be 1000's of rows for the output of machine 1 all with different status's - (all pre set in the Status table, i.e success, failure, rerun) and the same for lots of other machines held in the machine table.

What is the best to insert this data all in one go, rather than reading each row of the staging table one by one, looking up the foreign key values depending on the machine and status values, then inserting the data.

I was thinking along the lines of:

INSERT INTO dbo.LiveTable
(Information, MachineID, StatusId)
SELECT Staging.Information, dbo.Machine.MachineId, dbo.Status.StatusId
FROM dbo.Staging
JOIN Machine ON Machine.MachineName = Staging.MachineName
JOIN STATUS ON Status.Status = Staging.Status But I notice the problem with this is, it doubles up the inserts!

Doing A Data Import Using DTS Wizard In SQL Server 2005 - Being Efficient With 5 Flat Files

Apr 13, 2006

Hi,

I'm a new user of SQL Server 2005. I have the full version installed. I also have SQL Server Business Integration Dev Studio installed. My OS is Windows XP.

I'm importing a series of 5 flat files into a database on one of the SQL Servers we have. My goal is to get 5 different tables (though perhaps I should do one and add an extra field to distinguish each import) into the database for further analysis.

I tried doing an import via DTS Wizard. There are no column names in the flat file so I defined them during the import process (all 58 of them). When I got to the end, I had an option to save the import process as a SSIS (SQL Server Integration Service) Package on:

SQL SERVER (I don't have permission for this)

or

FILE SYSTEM (did this one)

I saved the Package locally in hopes of being able to go back in, change the source file and destination table of the package and quickly get the other 4 flat files imported.

My problems are:

1) I couldn't find how to run the *.DTSX Package file to run in SQL Server Studio (basically reuse the Package with minor changes and saving me having to redefine the same 58 columns on each flat file import)

2) Tried but didn't understand how to run it in SQL Server Bus Intel Dev Studio (i.e. understanding the mapping and getting the data types right so it wouldn't error out)

3) Don't know how to make the necessary changes so that the Package handles the next source file and puts in a new destination table (do I need to do 5 CREATE TABLES so this Package has a place to run to?)

4) Does the Package need to be part of a Project to run (I haven't found how to take an existing Package and make it part of a Project/Solution)?

5) Is there a good book or online resource for just getting the basics of using SQL Server 2005 and SQL Server Business Intelligence Development Studio?

I'm really at a loss after spending a day fruitlessly on it scouring the help files, forums and experimenting around.

Hope somebody can point me in the right direction.

Regards,

Patrick Briggs,

Doing A Data Import Using DTS Wizard In SQL Server 2005 - Being Efficient With 5 Flat Files

Apr 18, 2006

I just spent some time working out how to do a seemingly simple task. I��m sharing the steps I took to do this in hopes it saves other SQL Server 2005 users (especially newbies like myself) time.

My original question posed on several SQL newsgroups was based on this goal:

I'm importing a series of 5 flat files (all with same file layout) into a database on one of the SQL Servers we have using SQL Server 2005 (SQL Server Management Studio) . My goal is to get 5 different tables. I want to do this without having to redo all the layout criteria 4 additional times.

Below are the steps I followed to get a solution (all done in Microsoft SQL Server Management Studio):

Create the Package (data import)

1) Use the SQL Server Import Export Wizard (equivalent to SQL Server 2000 Data Transfer Wizard) to import your first flat file. At the CHOOSE DATA SOURCE window browse for your file.
2) Under the Advanced tab, you can set your Column attributes (��output column width�? or ��data type�? to name a few). I highlighted all the columns and selected ��string [DT_STR]�? for data type. To avoid truncation errors, I selected 255 for output column width. You can name the columns whose data you are most concerned with (I did import all the available fields).
3) After choosing a server destination you will have a ��SELECT SOURCE TABLES AND VIEWS�? window pop up. Under the ��Mapping�? column you can choose to tweak your mapping further editing in SQL (see Edit SQL button). I didn��t.
4) The ��SAVE AND EXECUTE PACKAGE�? will pop up. The ��Execute Immediately�? box should be checked and you should check the ��Save SSIS Package�? (SQL Server Integration Services). When you do, select ��File System�? for where to save this import-file-package to.
5) Click OKAY for the Package Protection Level and the ��SAVE SSIS PACKAGE�? window will appear. Browse for a path on your local computer to save to.

Modify Package (data import) for Next Use

6) In SQL Server Management Studio, browse for the Package and open it.

Preparation for SQL Task �� box

7) You should see a screen that shows two boxes (��Preparation for SQL Task�?) and (��Data Flow Task�?).
8) Right click on the former and select ��Edit�?.
9) On the ��SQL Statement�? row, click into the right column and select the ��? box
10) Change the destination table (the table you will create with this package) to a meaningful name and click OK.
11) Click OK for the ��SQL Task Editor�?

Data Flow Task - box

12) Right click on the ��Data Flow Task�? box and select ��Edit�?.
13) Three boxes will appear ��SourceConnectionFlatFile�?, ��Data Conversion 1�?, and ��Destination - <whatever table name your original data import went to>�?. Below them is a section that displays ��Connection Managers�?

SourceConnectionFlatFile - editing

14) The first thing you will want to do is change the import source to a new flat file. You do this by going below the boxes under the ��Connection Managers�? window and right clicking on ��SourceConnectionFlatFile�? and then selecting ��Edit�?
15) Browse for the new ��File Name�? and select it.
16) A ��Microsoft SQL Server Management Studio�? window will pop up asking you if you want to ��keep or reset the existing metadata�?. The metadata is just your column definitions and choosing ��YES�? to keep this makes sense if you are doing data imports on files with the same file layout.
17) Still in the ��Flat File Connection Manager Editor�? window, change the ��Connection Manager Name�? to something meaningful (I add <_> at the end and then the name of the table the flat file is going to) and click OK.

SourceConnectionFlatFile �� box (editing)

18) Right click on the ��SourceConnectionFlatFile�? box and select ��Edit�?.
19) Your newly named ��Flat File Connection Manager�? should appear in select box.
20) Click OK, right click again on the ��SourceConnectionFlatFile�? box and select ��Show Advanced Editor�?.
21) Under the ��Connections Manager�? tab, your newly named ��Flat File Connection�? should appear (the prior step is necessary for the advanced editor to recognize your change).
22) Under the ��Component Properties�? tab, on the ��Name�? row, click into the right column and rename to something meaningful (notice the ��Identification String�? row description changes too once you click out of the ��Name�? row)
23) Under the ��Column Mappings�? tab, just confirm you are mapping your flat file fields (��Available External Columns�?) to a destination table��s fields (��Available Output Columns�?).
24) Under the ��Input and Output Properties�? tab you can check in ��Flat File Source Output�? to make modifications to either your ��External Columns�? or your ��Output Columns�? �� you shouldn��t need to for a simple import.
((NOTE: any changes you make here would likely need to be consistent with the column properties found under the ��Connection Manager Window�? for the ��SourceConnectionFlatFile�? as well as the ��Data Conversion 1�? box under the ��Data Flow Tasks�? window, so exercise caution
25) NOTE: This process has worked for me by making my source columns all ��string [DT_STR]�? data type and the output columns all ��Unicode String [DT_WSTR]�? data type.

Data Conversion 1 �� box (editing)

26) There is nothing you need to do here. By right clicking on the ��Data Conversion 1�? box and selecting ��Edit�?, you can see and change the data type of the output columns (the ones in the table your importing the flat file to). There are probably more edits one can do but they��re beyond what I��ve learned.

Destination - <whatever table name your original data import went to> �� box (editing)

27) Right click on the ��Destination - <whatever table name your original data import went to>�? box and select ��Show Advanced Editor�?.
28) Select the ��Component Properties�? tab.
29) Select the right column at the ��Name�? row and change the name to something meaningful (ie. related to the source file name or the table name you��re importing to).
30) Select the right column at the ��Identification String�? row and it will update to this change.
31) Select the right column at the ��OpenRowSet�? and change it to the name of the table you are importing your flat file to (this should be consistent with table name under step 10).
32) Click OK
33) Select FILE and select ��Save As��? and then give your package a new name that��s meaningful (this will be helpful if you have to rerun the import of the flat file later).

Run (execute) the Revised Package (data import)

34) Go back to SQL Server Management Studio and open the Object Explorer
35) Connect to an ��Integration Services�? component. This should essentially be a local instance (not sure where it is on the local computer or in SQL Server Management Studio on the local computer).
36) In ��Object Explorer�? go down to your ��Integration Services�? object and expand it.
37) Expand ��Stored Packages�?
38) Right click on ��File System�? and select ��Import Package�? and an ��IMPORT PACKAGE�? window will appear
39) For ��Package Location�? choose ��File System�? and then browse for the ��Package Path�?
40) Click into the ��Package Name�? and it defaults to your Package��s file name.
41) Click OK and the Package is imported.
42) Right click on the newly imported Package and select ��Run Package�?
43) An ��Execute Package Utility�? window appears
44) Select ��Execute�? and the package runs.

Firing A Trigger When A User Updates Data But Not When A Stored Procedure Updates Data

Dec 19, 2007

I have a project that consists of a SQL db with an Access front end as the user interface. Here is the structure of the table on which this question is based:

Code Block

create table #IncomeAndExpenseData (
recordID nvarchar(5)NOT NULL,
itemID int NOT NULL,
itemvalue decimal(18, 2) NULL,
monthitemvalue decimal(18, 2) NULL
)
The itemvalue field is where the user enters his/her numbers via Access. There is an IncomeAndExpenseCodes table as well which holds item information, including the itemID and entry unit of measure. Some itemIDs have an entry unit of measure of $/mo, while others are entered in terms of $/yr, others in %/yr.

For itemvalues of itemIDs with entry units of measure that are not $/mo a stored procedure performs calculations which converts them into numbers that has a unit of measure of $/mo and updates IncomeAndExpenseData putting these numbers in the monthitemvalue field. This stored procedure is written to only calculate values for monthitemvalue fields which are null in order to avoid recalculating every single row in the table.

If the user edits the itemvalue field there is a trigger on IncomeAndExpenseData which sets the monthitemvalue to null so the stored procedure recalculates the monthitemvalue for the changed rows. However, it appears this trigger is also setting monthitemvalue to null after the stored procedure updates the IncomeAndExpenseData table with the recalculated monthitemvalues, thus wiping out the answers.

How do I write a trigger that sets the monthitemvalue to null only when the user edits the itemvalue field, not when the stored procedure puts the recalculated monthitemvalue into the IncomeAndExpenseData table?

How Can I Do A Multiple Insert Or Multiple Updates Or Inserts And Updates To The Same Table..

Oct 30, 2007

Hi...
I have data that i am getting through a dbf file. and i am dumping that data to a sql server... and then taking the data from the sql server after scrubing it i put it into the production database.. right my stored procedure handles a single plan only... but now there may be two or more plans together in the same sql server database which i need to scrub and then update that particular plan already exists or inserts if they dont...

this is my sproc...
ALTER PROCEDURE [dbo].[usp_Import_Plan]
@ClientId int,
@UserId int = NULL,
@HistoryId int,
@ShowStatus bit = 0-- Indicates whether status messages should be returned during the import.

AS

SET NOCOUNT ON

DECLARE
@Count int,
@Sproc varchar(50),
@Status varchar(200),
@TotalCount int

SET @Sproc = OBJECT_NAME(@@ProcId)

SET @Status = 'Updating plan information in Plan table.'
UPDATE
Statements..Plan
SET
PlanName = PlanName1,
Description = PlanName2
FROM
Statements..Plan cp
JOIN (
SELECT DISTINCT
PlanId,
PlanName1,
PlanName2
FROM
Census
) c
ON cp.CPlanId = c.PlanId
WHERE
cp.ClientId = @ClientId
AND
(
IsNull(cp.PlanName,'') <> IsNull(c.PlanName1,'')
OR
IsNull(cp.Description,'') <> IsNull(c.PlanName2,'')
)

SET @Count = @@ROWCOUNT
IF @Count > 0
BEGIN
SET @Status = 'Updated ' + Cast(@Count AS varchar(10)) + ' record(s) in ClientPlan.'
END
ELSE
BEGIN
SET @Status = 'No records were updated in Plan.'
END

SET @Status = 'Adding plan information to Plan table.'
INSERT INTO Statements..Plan (
ClientId,
ClientPlanId,
UserId,
PlanName,
Description
)
SELECT DISTINCT
@ClientId,
CPlanId,
@UserId,
PlanName1,
PlanName2
FROM
Census
WHERE
PlanId NOT IN (
SELECT DISTINCT
CPlanId
FROM
Statements..Plan
WHERE
ClientId = @ClientId
AND
ClientPlanId IS NOT NULL
)

SET @Count = @@ROWCOUNT
IF @Count > 0
BEGIN
SET @Status = 'Added ' + Cast(@Count AS varchar(10)) + ' record(s) to Plan.'
END
ELSE
BEGIN
SET @Status = 'No information was added Plan.'
END

SET NOCOUNT OFF

So how do i do multiple inserts and updates using this stored procedure...

Mass Updates In SQL Server

Oct 11, 2007

Does anyone know what the best way to do mass updates in SQL server is? I am currently using the methodology suggested in this article

http://www.tek-tips.com/faqs.cfm?fid=3141

But the article is assuming that once I update a field it is going to have a value that is NOT NULL. So I can loop through and update the rows that have a NOT NULL value. But my updated rows do contain NULL values, in this case what is the best way to go about this???

***************************************
Here is my code. I want to avoid using Upd_flag becos
after the following code runs I need to reset that flag
before I run my next query
***************************************

--Set rowcount to 50000 to limit number of inserts per batch
Set rowcount 50000

--Declare variable for row count
Declare @rc int
Set @rc=50000

While @rc=50000
Begin

Begin Transaction

--Use tablockx and holdlock to obtain and hold
--an immediate exclusive table lock. This usually
--speeds the insert because only one lock is needed.

update t_PGBA_DTL With (tablockx, holdlock)
SET t_PGBA_DTL.procedur = A.[Proc code],
t_PGBA_DTL.Upd_flag = 1
FROM t_PGBA_DTL
INNER JOIN CPT_HCPCS_I9_PROC_CODES A
ON t_PGBA_DTL.PROC_CD
= A.[Proc code]
WHERE t_PGBA_DTL.Upd_flag = 0

--Get number of rows updated
--Process will continue until less than 50000
Select @rc=@@rowcount

--Commit the transaction
Commit
End

Watching SQL Server For Updates

Aug 8, 2007

Here's the scenario:
* I have a database with a table
* I have a C# program which displays information about the data in the database
* If the data changes in the database, I wish for the client to pick it up and report the change

Is there a way to have some form of 'Event Handling' where the client will react to UPDATE queries on a table?

My thanks in advance.

Updates To Live Web Server

May 30, 2006

I'm developing a web app using ASP.NET and SQL Server 2005 Express. So far it's all been on my local computer, it hasn't gone live yet, so if I need to add a column to a table or make some other schema change I just do it right in Visual Studio, nice and simple. If I have to delete all the old content and start over, no problem. When I deploy it to a staging server I just overwrite the existing file with my new one, losing its data in the process. But soon enough I'll be deploying this to a public web server, there will be real live data in the db, people using it when I need to make updates.

What are some common strategies for updating the schema of a database on a live server?

It's obvious that when I need to update the db I'll have to shut down the site temporarily. But my biggest question is how to keep the existing data from the live db? I obviously can't overwrite it with my local copy. I want to overwrite its schema, without touching its data. How's that done?

Thanks for some advice!

Applying The Updates To SQL Mobile Server?!

Apr 14, 2006

Dear MSDN Support,

Here i am back with an inquiry about the last process of Merge Replication between SQL Mobile 2005 and SQL Server 2005.

Well i have performed all the steps found in the tutorial of the SQL Mobile Edition Books Online, and everything went on so fine and smooth. Now when i deploy my application on the Pocket PC emulator all possible SQL queries work and modify the data only in the emulator, i had installed ActiveSync 4.0 and it synchronizes the SQL Mobile data with the SQL Mobile server only when i copy the database from the emulator to my desktop, and this way is not efficient to my project, i need a better way to synchronize the data between the database on the emulator and that on the SQL Mobile Server.

I'll be looking forward to getting your help as soon as possible.

Thank you for your attention.

Best Regards;

Upgraded To SQL Server 2005. Updates No Longer Work. Error Could Not Find Server 'DEVDB' In Sysservers. Execute Sp_addlinkedse

Feb 28, 2006

Hello!

We just upgraded to SQL Server 2005 from SQL Server 2000. The DB was backed up using Enterprise Manager and restored with SQL Server Management Studio Express CTP. Everything went as expected (no errors, warnings, or any other indicator of problems).

The DB resides in a DB Server (Server1) and the application we are running is a Client/Server system where the AppServer resides on Server2.

During the application's operation all read, create, and delete transactions work fine but no update works. When viewing details in Trace Log I see this message after attempting any update:

Could not find server 'Server1' in sysservers. Execute sp_addlinkedserver to add the server to sysservers. (7202)

Any help is greatly appreciated,

SQL Server - Checking Inserts / Updates After DTS Package

Oct 30, 2007

Hi All,

I'm a relative novice on SQL Server and am a complete beginner at SQL, so am looking for a little help.

I currently use a DTS package to perform inserts / updates to a "production" table.

The DTS package transforms a comma separated file into a "temporary" table that is truncated / cleared before the load starts.

The temporary table has a column denoting Insert or Update. The production table is almost identical, however, doesn't contain the Insert / Update column. The DTS package then, depending upon the Insert / Update flag, either inserts data into the production table or updates data in the production table.

When the DTS package has completed, I'd like to be able to run an SQL Query that validates everything in the "temporary" table is identical to that in the "production" table, which it should be.

I have managed to do some queries to verify that everything has loaded / updated i.e. select primary_key from temporary table where primary_key not in (select * from production table), however, what I haven't been able to do is verify that all the columns on the temporary table match the values in the production table (excluding the Insert / Update flag).

I tried concatenating the columns in each table and comparing the concatenated values, however, this failed due to the different data-types, i.e. decimal, text etc.

Any help will be greatly appreciated.

Many thanks.

Cheers,

David

Why Does The Index Lock My Updates In SQL Server 2005?

Mar 28, 2006

When one process has one record locked in Update-Mode then an other process can't update any other records on that table with some queries, other queries that access the same records (but with a different WHERE statement) will execute.
This problem occurs with SQL Server 2005, but it didn't with SQL Server 2000 (or any other database).

The problem:
-Process 1 locks a record in the table, and keeps it in Update-Mode, because the user is editing it. (Using OLEDB Pessimistic Cursor-locking)
-Process 2 wants to update an other record, buts gets a "Lock timeout" when using one query but not with another.

For example this query will work :
UPDATE gwseqnumber SET nextseqnr = 3 WHERE row_id = 110;

But this qeury will give me a "Lock timeout" :
UPDATE gwseqnumber SET nextseqnr = 3 WHERE name = 'REC_2';

But it is the same record!!
The record with name = 'REC_2' has the row_id = 110, both values are unique in the table.

The data:
The table [gwseqnumber] has the following CREATE statement:
CREATE TABLE GWSEQNUMBER
(
    NEXTSEQNR                      INTEGER,
    NAME                      CHAR (20),
    ADMINISTRATIONCODE             INTEGER,
    FINDHIGHESTNUMBER              CHAR (1),
    CLOSEDYN                       CHAR (1),
    ROW_ID                      INT IDENTITY(1,1) NOT NULL
);

CREATE INDEX KEY_1 ON GWSEQNUMBER (NEXTSEQNR);
CREATE UNIQUE KEY_2 ON GWSEQNUMBER (ADMINISTRATIONCODE, NAME, IDENTIFIER);
CREATE UNIQUE INDEX KEY_3 ON GWSEQNUMBER (ROW_ID);

Both KEY_2 and KEY_3 are unique, KEY_1 is not.

If I remove the index on the NEXTSEQNR column (the index named KEY_1) then both these queries will work, so it is obviously related to the index.
Altough the index is obsolete and can be removed from this table, it should not result in bogus locking errors.

Even when i removed the index not all the queries will work. (With work i mean not run into a locking error, while the record is not even locked.)

Solutions tried:
- Set the compaitiblity level of the databsae back to 80 (for SQL Server 2000 compatibility).
- I have already tried to disable Page-Locking on all the indexes of this table.

So why does the index lock my updates in SQL Server 2005?
And how do i fix it so my database does not run into these locks?

SQL Server 2012 :: Full Updates To Transaction Table

Jun 27, 2014

I am basically trying to update a table which reflects account transactions. Accounts get paid in full but occasionally balance payments can be reversed and I want to update the table to show this - I need to show which period the account was previously paid in full.I've created a simplified version of the scenario and below are a couple of examples of things I've tried that do not work. I understand why they do not work but I'm struggling to figure out how to update the 'PeriodPrevPaidInFull' field.

create table Trans
(
AccNo int,
Transaction_Period_Index int,
PeriodOpeningBalance money,

SQL Server 2012 :: Trigger For Updates On A Row Using Previous Record Value?

Mar 9, 2015

I am looking to update a record from a previous row. So if there is a value of total goods in week 1, i want that value to carry forward to the value of goods in week 2. Is there any SQL as an example of the best way to accomplish this? I can query it using lag() which works great but i need the source data itself to update as the end-users are accessing the data via lightswitch, so when they save a change, i want the trigger (or whatever you recommend) to update the source table.

SQL Server 2005 SP2 Windows Updates Install On Vista X64

Mar 31, 2007

I'm currently running Windows Vista x64 and SQL server 2005 on an HP laptop with a AMD Turion 64 processor. I've install all of the Windows Vista x64 update so far with no issues. However, I'm unable to install SQL server 2005 SP2 via Windows updates.

I was able to successfully download the service pack with no issues and it is currenly on my machine ready to install. The system does take a check prior to the install process beginning to perform the install.

I continuely get and "Error Code A91" when the install process is running. As a result the install does not complete successfully. When I used the "Get Help" option I get a list of possible error conditions but none of them seem be useful. I checked each one and none of them provide any help with a solution.

I've successful installed SP2 on Vista x32 system with no problem. Is this a "Windows Update" issue?

Thanks

SQL Server 2012 :: Remove Some Database Updates From Transaction Scope?

Mar 4, 2015

I have a stored procedure that does the following

BEGIN TRANSACTION OUTERTXN

BEGIN TRANSACTION
Copy records from live to archive
END TRANSACTION with commit or rollback
execute sproc to write audit log with success or fail
IF transaction was committed
BEGIN TRANSACTION
Delete records from live the archive
END TRANSACTION with commit or rollback
execute sproc to write audit log with success or fail
End IF

END TRANSACTION OUTERTXN with commit if both inner transactions were successful or rollback if either failed

If either inner transaction rolled back execute sproc to write audit log saying whole process is rolling back End IfMy problem is that if the outer transaction rolls back then I am losing the two audit records because they are part of the transaction scope. I want these executes to commit even if the master transaction fails.

Access To SQL Server 2000 Pauses With Lots Of Inserts, Updates, ...

Nov 21, 2007

Hi,
I have the following problem: Within a VBScript, I use a component (written in C++ I think with use of ADO) for sending "Insert", "Update" Statements to an SQL Server 2000 for inserting, updating data. If I insert 100 - 120 Records in a Loop, all works fine. If I insert 1000 records, approximately 150 records will be inserted very quick, then the program pause fo approx. 8 - 15 minutes and then it proceed for the next 150 recs, pause for 8 - 15 minutes and so on.

If I use a SQL Server 2005 for the database, all works fine. The same happens with another customer and another program written in Visual Basic 6.0 with ADO. The access to SQL 2000 pause and with SQL 2005 all works fine. It seems to me that this is a problem with some buffers, timeout, or so. Has anyone an idea on what screw I can turn?

Thanks
Hans

Trace Auditing For ( New Records And Updates For A Particular Date) - SQL Server 2000 Sp4

Apr 26, 2007

Hi,

I have few tables. I want to identify the RECORDS for a table which has been created/modified for a particular date and time. I don't want to write a trigger to capture the event for add/update.

Is there any system table which track for date and time using stored procedure each individual records which has been last updated or newly created records??

Note : The application already created without lastModified date and each table... so, we don't want to modify the application or db.

Database : SQL Server 2000 sp4

thanks in advance.

SQL Server Does Not Exist Or Access Denied After Input Of Critical Updates

Aug 3, 2006

Hello guys och dolls.

I have a DTS program in sql-server 2000 which worked to week 27 but not from week 28. During that time I was on vacation och no one else was working with the server.

The part which is the problem looks like this.

if exists (select * from dbo.sysobjects where id = object_id(N'[lenko7].[aviskydd]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [lenko7].[aviskydd]
GO

CREATE TABLE [lenko7].[aviskydd] (
[Col002] [varchar] (255) NOT NULL,
[linecount] [int] NOT NULL
) ON [PRIMARY]
GO

I have not changed owner.

I don't understand why this DTS package suddenly cant work because it has been working for a several years with no problems. The only thing a know is that we have updated windows 2000 cause of a critical updates Juli 13.

Is there anyone who has the same problem.

Regards Stig Holmlund

Most Efficient DataSource?

Aug 3, 2007

Hi there,
I'm using a Repeater at the moment which is bound to a SQLDataSource. I expect much load on that Website, should I choose another DataSource? Which other DataSource is better if it's about Performance?
I read some stuff about the SQLAdapter and a DataSet.. is that better in performance? Why is it better?
What about LinQ?
Thanks a lot for any clarification.

More Efficient Code

Dec 13, 2007

Hi all, I have the code listed below and feel that it could be run much more efficiently. I run this same code for attrib2, 3, description, etc for a total of 21, so on each postback I am running a total of 21 different connections, i have listed only 3 of them here for the general idea. I run this same code for update and for insert, so 21 times for each of them as well. In fact if someone is adding a customer, after they hit the new customer button, it first runs 21 inserts of blanks for each field, then runs 21 updates for anything they put in fields, on the same records. This is running too slow... any ideas on how I can combine these?? We have 21 different entries for EVERY customer. The Pf_property does not change, it is 21 different set entries, the only one that changes is the Pf_Value.
Try                Dim queryString As String = "select Pf_Value from CustomerPOFlexField where [Pf_property] = 'Attrib1' and [Pf_CustomerNo] = @CustomerNo"                Dim connection As New SqlClient.SqlConnection("connectionstring")                Dim command As SqlClient.SqlCommand = New SqlClient.SqlCommand(queryString, connection)                command.Parameters.AddWithValue("@CustomerNo", DropDownlist1.SelectedValue)                Dim reader As SqlClient.SqlDataReader                command.Connection.Open()                reader = command.ExecuteReader                reader.Read()                TextBox2.Text = Convert.ToString(reader("Pf_Value"))                command.Connection.Close()            Catch ex As SystemException                Response.Write(ex.ToString)            End Try
            Try                Dim queryString As String = "select Pf_Value from CustomerPOFlexField where [Pf_property] = 'Attrib1Regex' and [Pf_CustomerNo] = @CustomerNo"                Dim connection As New SqlClient.SqlConnection("connectionstring")                Dim command As SqlClient.SqlCommand = New SqlClient.SqlCommand(queryString, connection)                command.Parameters.AddWithValue("@CustomerNo", DropDownlist1.SelectedValue)                Dim reader As SqlClient.SqlDataReader                command.Connection.Open()                reader = command.ExecuteReader                reader.Read()                TextBox5.Text = Convert.ToString(reader("Pf_Value"))                command.Connection.Close()            Catch ex As SystemException                Response.Write(ex.ToString)            End Try
            Try                Dim queryString As String = "select Pf_Value from CustomerPOFlexField where [Pf_property] = 'Attrib1ValMessage' and [Pf_CustomerNo] = @CustomerNo"                Dim connection As New SqlClient.SqlConnection("connectionstring")                Dim command As SqlClient.SqlCommand = New SqlClient.SqlCommand(queryString, connection)                command.Parameters.AddWithValue("@CustomerNo", DropDownlist1.SelectedValue)                Dim reader As SqlClient.SqlDataReader                command.Connection.Open()                reader = command.ExecuteReader                reader.Read()                TextBox6.Text = Convert.ToString(reader("Pf_Value"))                command.Connection.Close()            Catch ex As SystemException                Response.Write(ex.ToString)            End Try
