Insert/Update Sql Commands Not Saving To DB
Feb 23, 2007
Here is my problem :
I issue an insert statement to the db. While I am getting a
return value of 1 (1 row was affected) the values never show up into
the db when I open the DB in access. However, I can see the data
when it does an SQL select inside the program. So for instance, I
do an insert into ORDER values (1, 12, 5.99). (1 = item ID, 12 =
quantity, 5.99 = price). I then do a select * from Order, and I
get those values back. When I open the DB in access, in between
doing the insert and the select, I dont see the values there
either. It is like it is making a temporary copy of the DB in
memory during the execution only. When I close the program and
re-F5, the data is no longer there. Maybe we need some kind of
commit transaction? What am I doing wrong? I am using
VB.Net 2005/MS Access 2003. Here is the relevant code :
Private m_Connection As OleDbConnection
''' <summary>
''' Defines the path to the database.
''' </summary>
''' <remarks></remarks>
#If CONFIG = "Debug" Then
Public Const DB_PATH As String = "DBsDB_Test.mdb"
#ElseIf CONFIG = "Release" Then
Public Const DB_PATH As String = "DBsDB_Production.mdb"
#End If
Sub connect(ByVal p_path As String) Implements IPartyDBase.connect
Dim connect_string As String = "Provider=Microsoft.Jet.OLEDB.4.0;" _
& "Data Source=" & p_path
m_Connection = New OleDbConnection(connect_string)
m_Connection.Open()
End Sub
Sub someSub(ByVal stock As StockClass)
Dim tempString
Dim command As OleDbCommand
command = m_Connection.CreateCommand
command.CommandType = CommandType.Text
tempString = "Insert into Stock VALUES (" & stock.ID & ", "
tempString = tempString & stock.Quantity & ", "
tempString = tempString & stock.Price & ")"
Dim tempInt as Integer
command.CommandText = tempString
tempInt = command.ExecuteNonQuery
If Not tempInt = 1 Then
Throw New Exception("Bad addStockToDB into Stock " & tempInt)
End If
End Sub
Sub anotherSub
p_dbase.connect(PartyDBaseAccess.DB_PATH)
p_dbase.someSub()
p_dbase.close()
End Sub
Edit : During execution, looking under bin/debug/DBs, there is a copy
of the database that has all the transactions I did during execution...
but the actual DB isnt being updated/copied over.

Hi there,
I've had a look at this thread - http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=104399&SiteID=1 - but it's a bit old so I thought I'd try to clarify a couple of things.
I have a data flow which inserts or updates a table in a SQL 2000 database.
The insert is done via an OLE DB destination and the update is done via an OLE DB Command.
As stated in the previous thread, when these commands run concurrently issues arise with blocking etc.
The only way I've managed to get around it is by setting the access mode of the insert to OpenRowset.
So 2 questions:
1) Does anyone know how this problem occurrs and what the best way to get around it is?
2) Are there issues around NOT using the fast load options - I've read stuff about the double-byte character set etc but I admit I don't quite understand it.
Thanks.

I've just finished configuring the SELECT command for the SqlDataSource in my ASP.NET 2.0 web app. It works fine and runs against a SQL Server 2005 database, using a stored procedure that I've written.
So, then I went to configure the SqlDataSource for the UPDATE and INSERT commands, and I've written two SP's for those as well. In the designer the second form of the wizard asks for the Select statement. I've already given that for the SELECT statement in the third form, and I also select the INSERT tab to specify the SP I want to use for inserting data and the UPDATE tab to specify the SP I want to use for updating data. However, there appears to be no way that I can specify what the parameters are supposed to be for anything other than the SELECT command, through the designer. Is that correct, or have I missed something?

Hello, what i want is simple.
This is a simple forum, it has several topics (that the users can create), when a user create a topic, its stored in forum_topics. The user can then view the topic and post a response that is store in forum_answer, the user can also add this to his favorite list, forum_favorites is simple, contains a TopicID that refers to the topic, a username of the user that has the topic on his favorite list and a auto increment id to be able to delete specified topic favorites.
Now my question is: when a user posts a answer to Topic X, i want a predefined message to be sent to post_inbox for all the users that has Topic X in their favorite list.
How can i get MS SQL 2005 to get all the users from Topic X and then loop thru them and insert a new post into post_inbox?

I'm running a update on a table and it appears to work. But when I check the data about 10 mins later it has been reversed back to the original form!

Wondering what's the preferred method for this. I've got a scenario that a user is updating some content on a page and I need to update my word catalogs for my search feature. I have some code currently to filter out words that are too small, make sure there are no duplicates and to count how many occurrences there are of each. What I'm wondering is, does it make more sense to do a loop in my code to run all the insert commands to place the new words in the database, should I try sticking them together in one string and parse them when they get up there or is there a better method someone can suggest?

I'm building a simple webform, except Visual Studio and my service provider have combined to drive me nutty.
First, I MUST use an ODBC connection to my remote SQL Server do to some unknown configuartion problem. I've been playing with Visual Studio for only a month, so normally when something goes wrong I can go look in the mirror and find the culprit. This is different. I've got a totally functional web form with a SQL Connection, but when I try to change it to an ODBC Connection, I get the following error.
An OdbcParameter with ParameterName '@CertHolder' is not contained by this OdbcParameterCollection
My coding is fine because I stole it straight from the walkthrough and it works. But the specifications that Visual Studio provide are quite suspect. Please note the failure to include some key "@" signs.

Hello everyone
I'm very new to SSIS and seemed to have stumbled into an expected problem. I'm working on a package that was converted from a DTS package and I have a problem with the Flat File Connection manager. I want to change the file name in my connection, but I do not seem to be able to save the change. After clicking "OK" to save the name change I can then save the package, close BIDS, open everything up again and for some reason the "old" filename is still present in the connection. Note that the "new" file has exactly the same layout as the "old" file, just a different name. And I can oreview the data without any difficulty.
Any ideas on this one...?
Thanks, John

Hi,
I have an application where I'm filling a dataset with values from a table. This table has no primary key. Then I iterate through each row of the dataset and I compute the value of one of the columns and then update that value in the dataset row. The problem I'm having is that when the database gets updated by the SqlDataAdapter.Update() method, the same value shows up under that column for all rows. I think my Update Command is not correct since I'm not specifying a where clause and hence it is using just the value lastly computed in the dataset to update the entire database. But I do not know how to specify a where clause for an update statement when I'm actually updating every row in the dataset. Basically I do not have an update parameter since all rows are meant to be updated. Any suggestions?
SqlCommand snUpdate = conn.CreateCommand();
snUpdate.CommandType = CommandType.Text;
snUpdate.CommandText = "Update TestTable set shipdate = @shipdate";
snUpdate.Parameters.Add("@shipdate", SqlDbType.Char, 10, "shipdate");
string jdate ="";
for (int i = 0; i < ds.Tables[0].Rows.Count - 1; i++)
{
jdate = ds.Tables[0].Rows[i]["shipdate"].ToString();
ds.Tables[0].Rows[i]["shipdate"] = convertToNormalDate(jdate);
}
da.Update(ds, "Table1");
conn.Close();
-Thanks

Hi Guys,
I am trying to automate a basic task using SQL Server 2005 Express.
Currently I have a query script that I run and then save the results as a CSV file. I need to do this on a daily basis and so I am looking to find out how best to go about this. There are a multitude of third party tools that claim to be able to do this - can anyone recommend this or enlighten me of the best way to set up this automation.
All ideas gratefully received!

If I have a table with 1 or more Nullable fields and I want to make sure that when an INSERT or UPDATE occurs and one or more of these fields are left to NULL either explicitly or implicitly is there I can set these to non-null values without interfering with the INSERT or UPDATE in as far as the other fields in the table?
EXAMPLE:
CREATE TABLE dbo.MYTABLE(
ID NUMERIC(18,0) IDENTITY(1,1) NOT NULL,
FirstName VARCHAR(50) NULL,
LastName VARCHAR(50) NULL,
[Code] ....
If an INSERT looks like any of the following what can I do to change the NULL being assigned to DateAdded to a real date, preferable the value of GetDate() at the time of the insert? I've heard of INSTEAD of Triggers but I'm not trying tto over rise the entire INSERT or update just the on (maybe 2) fields that are being left as null or explicitly set to null. The same would apply for any UPDATE where DateModified is not specified or explicitly set to NULL. I would want to change it so that DateModified is not null on any UPDATE.
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
VALUES('John','Smith',NULL)
INSERT INTO dbo.MYTABLE( FirstName, LastName)
VALUES('John','Smith')
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
SELECT FirstName, LastName, NULL
FROM MYOTHERTABLE

I have a web form with a text field that needs to take in as much as the user decides to type and insert it into an nvarchar(max) field in the database behind. I've tried using the new .write() method in my update statement, but it cuts off the text after a while. Is there a way to insert/update in SQL 2005 this without resorting to Bulk Insert? It bloats the transaction log and turning the logging off requires a call to sp_dboptions (or a straight-up ALTER DATABASE), which I'd like to avoid if I can.

I'm working on inserting data into a table in a database. The table has two separate triggers, one for insert and one for update (I don't like it this way, but that's how it's been for years). When there is a normal insert, done via a program, it looks like the triggers work fine. When I run an insert manually via a script, the first insert trigger will run, but the update trigger will fail. I narrowed down the issue to a root cause.
This root issue is due to both triggers using the same temporary table name. When the second trigger runs, there's an error stating that a few columns don't exist. I went to my test server and test db and changed the update trigger so that the temporary table is different than the insert trigger temporary table, the triggers work fine. The weird thing is that if the temporary table already exists, when the second trigger tries to create the temporary table, I would expect it to fail and say that it already exists.I'm probably just going to update the trigger tonight and change the temporary table name.

Hello,I am writing a stored procedure that will take data from severaldifferent tables and will combine the data into a single table for ourdata warehouse. It is mostly pretty straightforward stuff, but there isone issue that I am not sure how to handle.The resulting table has a column that is an ugly concatenation fromseveral columns in the source. I didn't design this and I can't huntdown and kill the person who did, so that option is out. Here is asimplified version of what I'm trying to do:CREATE TABLE Source (grp_id INT NOT NULL,mbr_id DECIMAL(18, 0) NOT NULL,birth_date DATETIME NULL,gender_code CHAR(1) NOT NULL,ssn CHAR(9) NOT NULL )GOALTER TABLE SourceADD CONSTRAINT PK_SourcePRIMARY KEY CLUSTERED (grp_id, mbr_id)GOCREATE TABLE Destination (grp_id INT NOT NULL,mbr_id DECIMAL(18, 0) NOT NULL,birth_date DATETIME NULL,gender_code CHAR(1) NOT NULL,member_ssn CHAR(9) NOT NULL,subscriber_ssn CHAR(9) NOT NULL )GOALTER TABLE DestinationADD CONSTRAINT PK_DestinationPRIMARY KEY CLUSTERED (grp_id, mbr_id)GOThe member_ssn is the ssn for the row being imported. Each member alsohas a subscriber (think of it as a parent-child kind of relationship)where the first 9 characters of the mbr_id (as a zero-padded string)match and the last two are "00". For example, given the followingmbr_id values:1234567890012345678901123456789021111111110022222222200They would have the following subscribers:mbr_id subscriber mbr_id12345678900 1234567890012345678901 1234567890012345678902 1234567890011111111100 1111111110022222222200 22222222200So, for the subscriber_ssn I need to find the subscriber using theabove rule and fill in that ssn.I have a couple of ideas on how I might do this, but I'm wondering ifanyone has tackled a similar situation and how you solved it.The current system does an insert with an additional column for thesubscriber mbr_id then it updates the table using that column to joinback to the source. I could also join the source to itself in the firstplace to fill it in without the extra update, but I'm not sure if theextra complexity of the insert statement would offset any gains fromputting it all into one statement. I plan to test that on Monday.Thanks for any ideas that you might have.-Tom.

Is there an easy way with DTS to pump data from one table to another so that it will update the row if it exists (the source and destination have the same value for the ID colum) or insert it if it doesn't.
I know this can be done with stored procedures/sql by doing IF EXISTS UPDATE ELSE INSERT but there are many tables and columns and this will be very tiime consuming.

I have a page where the user can update stock records. it has 5 x 5 text boxes. If the user has already entered stock before that stock will show up and they can change it and clicking the button it will update, however if they have just entered new data i would assume they would need to insert it, so how do i go about doing this? do i need to use both insert and update in the same sql string?

greetings
I am developing an application for the marketing dept at my company.
Basically users can build the content of an email to be sent to our
subscriber database.
I am wanting the application to initailly save the content into a database, the update the most recently inserted row.
The save button uses the following SQL command:
Dim SqlMethod As String =
"INSERT INTO CZC_email (Offer, SendDate, Destinations, Copy, BannerURL)
VALUES ('" & txtCampaignName.Text & "','" &
calCampaignDate.SelectedDate.ToString("yy/dd/MM") & "','" &
DestinationsSelected & "','" & FreeTextBox2.Text & "', '"
& txtBannerPath.Text & "')SELECT @@IDENTITY AS 'CZ_ID'"
And my update button has this SQL command:
Dim SqlMethod As String =
"UPDATE CZC_email SET SendDate = '" &
calCampaignDate.SelectedDate.ToString("yy/dd/MM") & "', Offer = '"
& txtCampaignName.Text & "',Destinations = '" &
DestinationsSelected & "', BannerURL = '" & txtBannerPath.Text
& "' WHERE CZ_ID = @@IDENTITY "
but it doesnt seem to be updating. anyone know what I'm doing wrong?

I have a GridView on a page, It contains data from 2 joined tables and a command column to Edit/Update. I want to update the data in only one of the tables. If the data exists in the table to be updated there seems to be no problem (obviously). But I get an error when trying to update a record that does not exist (I should think so). Is there a way of Inserting the record before the update is fired?

Is it possible to run a DTS package so that it just updates existing rows rather than a full on insert?
I have an HR db as a source and a health and safety db as destination. records of peoples H+S acheivments and assessments are maintained in the H+S db but i need to keep this topped up with the newly recruited staff details and the existing staff change of details. The DTS need to know to insert where its a new record and to update where its just a change of name or work location etc.
if DTS wont do this, what are my options?
TIA

I have a form that pulls existing information from a database and allows users to edit it. Every field can be left blank if the user wishes. I am having an issue with determining which SQL statement to run. There has to be an easier way to do this then what I am doing. For each filed I process the data this way:
SQL2="select * from 1985ClassList where MailingListID =" & Session("EID")
set aData = oConn.execute(SQL2)
SQL = "Update 1985ClassList SET "
if aData.Fields("FirstName") > " " and Request.QueryString("FirstName") > " " then
SQL = SQL & "'FirstName' = '" & Request.QueryString("FirstName") & "', "
end if
if aData.Fields("FirstName") = " " and Request.QueryString("FirstName") > " " then
strFSQL = strFSQL & "FirstName, "
strVSQL = strVSQL & Request.QueryString("FirstName") & ", "
end if
SQL = SQL & "where MailingListID =" & Session("EID")
set mData = oConn.execute(SQL)
if strFSQL > " " then
SQL1 = "Insert into 1985ClassList " & strFSQL & "VALUES " & strVSQL
end if
set mData = oConn.execute(SQL1)
It works fine for the UPDATE, but not for the INSERT.

Scenario :
MS SQL 2005
Tables:
DETAIL --Here are all the detailed transactions
Customer
Item
Amount
...MoreFields
TOTAL --Here are the accumulated values (1 record by Customer-Item
Customer
Item
Accumulated
...MoreFields
What I want to know is the general logic to
-Read all records from table DETAIL
-If relationship Customer-Item exists in TOTAL table then UPDATE the TOTAL.Accumulated field adding the DETAIL.Amount field
-If relationship Customer-Item doesn't exists in TOTAL table then INSERT a new ecord with the values from DETAIL table
Because of my experience in VB and ADO my first try is to use a Cursor and loop record by record
But I know that is not the only and better solution
May You post some hint or some sample querie on how could be done
Thanks

I'm new to DTS. I read some docs before adventuring into this matter.I still haven't found in all the docs I read if there is some "built-in" DTStask or function or wathever, to do a mixed "insert/update" import from asource, giving a unique field as primary key.I'll try to be more specific. The problem I would like to solve is this:I have a source file (csv) but it could be any source. I must check thisfile for all the records and compare them with the ones in the db (giving aunique field as a way of checking), so that all the records that alreadyexist, are UPDATED, and the others are INSERTED.I guess this is one most common task to accomplish, when you have a localbased application that you regularly update and then you want to export thedata to another "slave" application without using replication. But even ifthis sounds to me like a common task, I found no "buil-in" function for thatin DTS. I read something about "lookups" but it don't know if it's relatedsomehow.. it wasn't very clean.Thanks in advance for suggestions.--:: Massimiliano Mattei:: Project Leader:: E.xtranet V.irtual A.pplication:: www.evagroup.net :: www.commy.biz

Hi Team,
I would like to import a .csv file into my existing table. On the DTS, I would like to check if the record already there then updated, on the other hand, if the record wasn't there then add it. How can I do that using DTS. Please help and thanks.

table2 is intially populated (basically this will serve as historical table for view); temptable and table2 will are similar except that table2 has two extra columns which are insertdt and updatedt
process:
1. get data from an existing view and insert in temptable
2. truncate/delete contents of table1
3. insert data in table1 by comparing temptable vs table2 (values that exists in temptable but not in table2 will be inserted)
4. insert data in table2 which are not yet present (comparing ID in t2 and temptable)
5. UPDATE table2 whose field/column VALUE is not equal with temptable. (meaning UNMATCHED VALUE)
* for #5 if a value from table2 (historical table) has changed compared to temptable (new result of view) this must be updated as well as the updateddt field value.
