Inserting And Updating From An Import Table

Jun 9, 2006

SQLNewbie writes "I have a table 'ImportedListings' that is populated with data external to the database. This table is only used to hold the data until I can move it to the permanent table 'Listings' at which point 'ImportedListings' gets truncated to nothing. Both tables contain almost identical data and structure. There is a listing ID column available for joins.

Basically I need to compare each row in ImportedListing and if it already exists in Listing, UPDATE Listing with the new info. If the row in ImportedListing doesn't exist in Listing, I need to INSERT it.

Physically deleting rows from the listings table is not an option. Do you have any ideas on how I can do this? I initially tried using a temp table to hold the matching listing id's but I could not get figure out the update statement with this scenario.

Thanks for any help! I have been trying to hammer this out all night(I just started programming tsql)"

Updating A Table By Both Inserting And Updating In The Data Flow

Sep 21, 2006

I am very new to SQL Server 2005. I have created a package to load data from a flat delimited file to a database table. The initial load has worked. However, in the future, I will have flat files used to update the table. Some of the records will need to be inserted and some will need to update existing rows. I am trying to do this from SSIS. However, I am very lost as to how to do this.

Any suggestions?

Inserting And Updating And Array Into An SQL Table

Dec 23, 2003

I have an asp.net project that displays a timesheet based on a fortnightly system.

It has a Y and X axis, i.e. Sun-Mon, Sun-Mon across the top and Categories of hour types accross the Y axis, i.e. Holidays, Overtime, Maintenance.

I was using a datagrid to gather the rows, but I need to have the whole grid in edit mode which is something that requires more coding. So I have swapped to a datalist.

It will take me 240 fields to store all the data in their corresponding fields. So I basically need to know if there is an easier way to store two dimensional array type data into an SQL table using a minimum of fields.

Deleting, Updating And Inserting---is It LOCKING The Table?

Aug 17, 2006

I have created a single Data Flow Task that reads a set of records from a source table and then makes determinations whether to insert, update or delete from a destination table. The data is basically being copied from one database to another with a small amount of data manipulation and lookups. The problem seems to be that when running the task, even a small amount of records read from the source table seem to take a long time for the task to finish. I feed the records into a Script Component (the brains) that sorts the records to three separate outputs. I use OLE DB Commands to perform the DELETE and UPDATE and an OLE DB Destination for INSERT. I thought that by using three separate database connections would help, but it just appears to be locked while trying to perform these commands against the same table.

Is there a way to control or route these three record sets in such a way as to perform them sequentially?

I know it's a bit of a simple question for some of you, but I'm just learning SSIS (but I like it!).

Thanks!

Updating/Inserting Rows

Jul 16, 2002

Does anybody have a sample SQL script that will select table A and compare it to table B. If a row exists in both table A and table B, it will update the columns in table B with the columns in table A. If the row does not exist in table B, it will insert a row in table B using the row in table A. Is this possible?

Thanks Mitch

Inserting / Updating LongText Field Using WriteText?

Jul 20, 2005

Hi, I'm trying to store large strings to a database, so am using thetext field type (LongText). I have used this before when storing thehtml of a webpage, and was able to store more than 255 characters byusing just a normal update sql statement. Now I'm trying to store thebody of research papers, and must be doing something different, as Ican only store 255 characters.Can someone explain why SQL Server doesn't like what I am doing -should I be using the WriteText / UpdateText function? If so, pleaseexplain by example how I would do that, and why doing that works.Thanks so much,Iain

Converting Empty String To Null When Inserting/updating

Mar 10, 2006

    I am using the following query to calculate date differences:select ..........DATEDIFF(d,  recruitment_advertising.advertising_date, career_details.RTS_Email AS Datetime) AS Ad_to_RTS_days FROM .....I have stored all my dates as NVARCHAR because of the issues with localization.If the value is an empty String my output is eg: -38700. which is way off and incorrect. Some of the values in my table are NULL and they produce the correct result.Is there a T-SQL statement to replace empy Strings with the NULL value in my tables.I'd like to use it as a trigger when inserting or updating to convert empty strings to NULLbefore the values are inserted.Thanks guys.

Inserting And Updating Unicode Strings Via Oracle Provider For OLE DB

Mar 8, 2007

We've installed the Oracle provider for OLE DB on SQL Server 2005, which has the default collation (SQL_Latin1_General_CP1_CI_AS), and we've created a linked server for the Oracle 9.2.0.5 database, which has AL32UTF8 as the database character set. We can successfully insert strings into VARCHAR2 columns on Oracle from SQL Server via EXEC SP_EXECUTESQL('INSERT OPENQUERY(...) VALUES(...)') -- as long as the strings (whether selected from NVARCHAR columns on SQL Server or specified as literals with the N prefix during testing) only contain Windows-1252 characters.

If the SQL statement contains a character above U+00FF, the string on the Oracle side is incorrectly/doubly encoded; there are nearly (but not exactly) 4 bytes per character instead of the 1 or 2 you'd expect from ASCII/Latin-1 characters encoded as UTF-8.

We've tried reconfiguring the linked server: collation compatible = false, use remote collation = true, and collation name = Latin1_General_BIN2. But that had no effect.

What is the correct way to do this?

Thanks!

Unspecified Error When Inserting/updating Record Using SqlCeResultSet On Sql Compact

Nov 14, 2007

Hi,

Inside a single transaction I'm inserting/updating multiple records into multiple tables, in this order:
table 1 record 1
table 2 record 1
table 3 record 1
table 1 record 2
table 2 record 1
table 1 record 3
table 2 record 3
table 3 record 3


Now I'm getting an unspecified error on a certain table:

Unspecified error [ 3,-1300704038,-1834095882,activitypointerBase,x lock (x blocks),PAG (idx): 1078 ]


From msdn I see that:


PAG (idx) means a lock on an index page.

x lock means an exclusive lock:

Indicates a data modification, such as an insert, an update, or a deletion. Ensures that multiple updates cannot be made to the same resource at the same time. (I assume that multiple updates within the SAME transaction can be made, only multiple updates from different transaction cannot be made, right?)
I cannot find any reference to this error message and don't know what the numbers mean. Maybe it relates to data that can be found in the sys.lock_information table like explained here, http://technet.microsoft.com/en-us/library/ms172932.aspx, but I'm not sure.

Furthermore, the sys.lock_information table is empty. I haven't been able to reproduce the problem myself. I only received an error log and the database to investigate it.

So, does anybody have an idea what this error message means and what I can do to troubleshoot this?

Thanks,
Jeffry

Database Automatically Creates Xxx_Temp Table While Modifying / Updating Table Structure .

Dec 16, 2007

Hello friends,

I am new to the SQL Server 2005 development.

From last 1 week or so, i have been facing very strange problem with my sql server 2005s database
which is configured and set on the hosting web server. Right now for managing my sql server 2005 database,
i am using an web based Control Panel developed by my hosting company.

Problem i am facing is that, whenever i try to modify (i.e. add new columns) tables in the database,
it gives me error saying that,

"There is already an object named 'PK_xxx_Temp' in the database. Could not create constraint. See previous errors.
Source: .Net SqlClient Data Provider".

where xxx is the table name.

I have done quite a bit research on the problem and have also searched on the net for solution but still
the problem persist.

Thanks in advance. Any help will be appreciated.

Error Inserting Image Into SQL Server2000 Table From Pocket PC Application Only When Using Stored Procedure In Table Adapter Wiz

Apr 24, 2008

My Pocket PC application exports signature as an image. Everything is fine when choose Use SQL statements in TableAdapter Configuration Wizard.


main.ds.MailsSignature.Clear();

string[] signFiles = Directory.GetFiles(Settings.signDirectory);


foreach (string signFile in signFiles)

mailsSignatureRow.Singnature = GetImageBytes(signFile); //return byte[] array of the image.

main.ds.MailsSignature.Rows.Add(mailsSignatureRow);

}


mailsSignatureTableAdapter.Update(main.ds.MailsSignature);

But now I am getting error "General Network Error. Check your network documentation" after specifying Use existing stored procedure in TableAdpater Configuration Wizard.


ALTER PROCEDURE dbo.Insert_MailSignature( @Singnature image )

AS

SET NOCOUNT OFF;

INSERT INTO MailsSignature (Singnature) VALUES (@Singnature);



SELECT Id, Singnature FROM MailsSignature WHERE (Id = SCOPE_IDENTITY())

For testing I created a desktop application and found that the same Code, same(Use existing stored procedure in TableAdpater Configuration Wizard) and same stored procedure is working fine in inserting image into the table.

Is there any limitation in CF?

Inserting Distinct Data From One Table In Another Table, How?!?Really Urgent And Needing Help!!!

May 24, 2007

 Hi, I have a table in which I will insert several redundant data. Don't ask why, is Integration services, it only reads data and inserts it in a SQL table. THis way, I have a SQL table with several lines repeating them selves. What I want to do is create a procedure that reads the distinct data and inserts it in another table, but my problem is that I am not able to select data line by line on the original table to save it in local variables and insert it on the another table, I just can select the last line. I've tried a while cycle but no succeed. Here is my code: create proc insertLocalizationASdeclare @idAp int, @macAp varchar(20), @floorAp varchar(2), @building varchar(30), @department varchar(30)select @idAp = idAp from OLTPLocalization where idAp not in (select idAp from dimLocalization)select @macAp=macAp,@floorAp=floorAp,@building=building,@department=department from OLTPLocalizationif (@idAp <> null)beginInsert into dimLocalization VALUES(@idAp,@macAp,@floorAp,@building,@department)endGO This only inserts the last line in the "oltpLocalization" table. O the other hand, like this:create proc aaaaasdeclare @idAp as int, @macAp as varchar(50), @floorAp as int, @building as varchar(50), @department as varchar(50)while exists (select distinct(idAp) from OLTPLocalization)begin    select @idAp =idAp from OLTPLocalization  where idAp not in (select idAp from dimLocalization)    select @macAp = macAp from OLTPLocalization where idAp = @idAp    select @building = building from OLTPLocalization where idAp = @idAp    select @department = department from OLTPLocalization where idAP = @idApif (@idAp <> null)begin    insert into dimLocalization values(@idAp,@macAp,@floorAp,@building,@department)endendgo this retrieves every distinct idAp in each increment on the while statement. The interess of the while is really selecting each different line in the OLTPLocalization table. I did not find any foreach or for each statement, is there any way to select distinct line by line in a sql table and save each column result in variables, to then insert them in another table? I've also thought about web service, that reads the distinct data from the oltpLocalization into a dataset, and then inserts this data into the dimLocalization table. Is there anything I can do?Any guess?Really needing a hand here!Thanks a lot!

DELETE

WHERE fi_gnmaid IN (
SELECT DISTINCT r2.fi_gnmaid
FROM #revf r1, #revf r2

[Code] ...

I don't want to create this #rev table so that i can avoid the delete statement. But data should not affect. Can i rewrite the above as below:

SELECT [Cusip], [sponfID], GroupSeries, [tran], [AddDate], [SetDate], [PoolNumber], [Aggregate], [Price], [NetAmount], [Interest],
[Coupon], [TradeDate], [ReversalDate], [Description], [ImportDate], MAX([fi_gnmaid]) AS Fi_GNMAID, accounttype, [IgnoreFlag], [IgnoreReason], IncludeReversals, DatasetID, [DeloitteTaxComments], [ReconciliationID],

Sep 18, 2014

I have a 2010 SSIS package where I am reading csv files with different fields and formatted data, I have created separate packages for each file and I am formatting the data to fit the final destination tables data elements, I've been instructed to create 7 separate packages to read each file and the format the data from the 7 csv files, and insert into their table tbl1, tbl2, tbl3...etc then, I'm taking a execute sql task and wanting to insert the tbl1, tbl2, tbl3...etc into destination table that will be the final table for all reports and other uses.

1- should I create a ID?
2- these files will be read once a month
3- I want to append the data, not drop and recreate each run,
4- It's 2012 SQL and 2010 SSIS

Each csv file is in a different format, some have 15 columns, other have 8 I have to parse the data, in SP to align with the fields in the destination table.

5- Can I force RowID to be the next auto gen number from tbl1,for the start of insert for tbl2, then last row of tbl2 for insert of tbl3???

Calculating Value From Two Separate Rows In The Same Table And Inserting As New Row In The Same Table

Hi,

I'm working on a database for a financial client and part of what i need to do is calculate a value from two separate rows in the same table and insert the result in the same table as a new row. I have a way of doing so but i consider it to be extremely inelegant and i'm hoping there's a better way of doing it. A description of the existing database schema (which i have control over) will help in explaining the problem:

id metric_type_id metric_type_name
1 1 Raw
2 2 Fiscal
3 3 Calendar
4 4 Calculated

The problem scenario is the following: Because a certain number of the securities have a fiscal year end that is different to the calendar end in addition to having fiscal data (such as fiscal enterprise value and fiscal earnings etc...) for each security i also need to store calendarised data. What this means is that if security with security_id = 3 has a fiscal year end of October then using rows with ids = 1, 2, 3 and 4 from the metrics_ladder table i need to calculate metrics with metric_id = 83, 84, 85 and 86 (as described in the metric_details table) and insert the following 4 new records into metrics_ladder:

id security_id metric_id value
1 3 101 <calculated value>
2 3 102 <calculated value>
3 3 103 <calculated value>
4 3 104 <calculated value>

Metric with metric_id = 101 (Calendar Enterprise value Historic Year 1) will be calculated by taking 10/12 of the value for metric_id 80 plus 2/12 of the value for metric_id 81.

Similarly, metric_id 102 will be equal to 10/12 of the value for metric_id 81 plus 2/12 of the value for metric_id 82,

metric_id 103 will be equal to 10/12 of the value for metric_id 82 plus 2/12 of the value for metric_id 83 and finally

metric_id 104 will be NULL (determined by business requirements as there is no data for forward year 3 to use).

As i could think of no better way of doing this (and hence the reason for this thread) I am currently achieving this by pivoting the relevant data from the metrics_ladder so that the required data for each security is in one row, storing the result in a new column then unpivoting again to store the result in the metrics_ladder table. So the above data in nmetrics_ladder becomes:

security_id 80 81 82 83 101 102
----------- -- -- -- -- -- --
3 125.45 548.45 145.14 123.32 <calculated value> <calculated value>
4 ...
.
.
.

which is then unpivoted.

The SQL that achieves this is more or less as follows:

*********
START SQL
*********

declare @calendar_averages table (security_id int, [101] decimal(38,19), [102] decimal(38,19), [103] decimal(38,19), [104] decimal(38,19),etc...)


-- Dummy year variable to make it easier to use MONTH() function
-- to convert 3 letter month to number. i.e. JAN -> 1, DEC -> 12 etc...
DECLARE @DUMMY_YEAR VARCHAR(4)
SET @DUMMY_YEAR = 1900;

with temp(security_id, metric_id, value)
as
(
select ml.security_id, ml.metric_id, ml.value
from metrics_ladder ml
where ml.metric_id in (80,81,82,83,84,85,86,87,88,etc...)
-- only consider securities with fiscal year end not equal to december
and ml.security_id in (select security_id from company_details where fiscal_year_end <> 'dec')
)
insert into @calendar_averages
select temppivot.security_id
-- Net Income
,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[80])
+((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[81]) as [101]
,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[81])
+((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[82]) as [102]
,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[82])
+((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[83]) as [103]
,NULL as [104]
-- Share Holders Equity
,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[84])
+((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[85]) as [105]
,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[85])
+((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[86]) as [106]
,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[86])
+((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[87]) as [107]
,NULL as [108]
-- Capex
-- Sales
-- Accounts payable
etc...
..
..
from temp
pivot
(
sum(value)
for metric_id in ([80],[81],[82],[83],[84],[85],[86],[87],[88],etc...)
) as temppivot
inner join company_details cd on temppivot.security_id = cd.security_id

*********
END SQL
*********

The result then needs to be unpivoted and stored in metrics_ladder.

And FINALLY, the question! Is there a more elegant way of achieving this??? I have complete control over the database schema so if creating mapping tables or anything along those lines would help it is possible. Also, is SQL not really suited for such operations and would it therefore be better done in C#/VB.NET.

Many thanks (if you've read this far!)

Updating Table Referencing 2nd Table Using Case

Feb 9, 2008

Hi

Im trying to create an update statement which references two tables (join) and has a CASE clause attached. Not sure where im going wrong...

Using T-sql!!!

update import set import.gone =
from import
inner join stat
ON stat.id = import.id
CASE
WHEN stat.A = import.field2 THEN import.gone = sec.A
WHEN stat.B = import.field2 THEN import.gone = sec.B
WHEN stat.C = import.field2 THEN import.gone = sec.C
WHEN stat.D = import.field2 THEN import.gone = sec.D
WHEN stat.E = import.field2 THEN import.gone = sec.E
WHEN stat.F = import.field2 THEN import.gone = sec.F
ELSE import.gone = null
END

Any help would be greatly appreciated

Updating A Table With Data From A Temp Table

Oct 19, 2007

I am trying to update a table in one database with data from a temporary table which i created in the tempdb.

I want to update field1 in the table with the tempfield1 from the #temp_table

The code looks something like this:

Use master
UPDATE [dbname].dbo.table
SET [dbname].dbo.table.field1 = [tempdb].dbo.#temp_table.tempfield1
WHERE ( [dbname].dbo.table.field2= [tempdb].dbo.#temp_table.tempfield2
AND [dbname].dbo.table.field3= [tempdb].dbo.#temp_table.tempfield3
AND [dbname].dbo.table.field4= [tempdb].dbo.#temp_table.tempfield4)

I get the following error:
Msg 4104, Level 16, State 1, Line 2
The multi-part identifier "tempdb.dbo.#temp_table.tempfield2" could not be bound.
Msg 4104, Level 16, State 1, Line 2
The multi-part identifier "tempdb.dbo.#temp_table.tempfield3" could not be bound.
Msg 4104, Level 16, State 1, Line 2
The multi-part identifier "tempdb.dbo.#temp_table.tempfield4" could not be bound.

What is wrong?
