Update Statement Not Working
Oct 2, 2007
I have the following update statement, which when executed, updates zero rows. However, if I replace the first two lines with a SELECT * , I will get records. Can somebody tell me why?
UPDATE [DW_DatamartDB]. [dbo].[FactLaborDollars]
SET [LaborBudget_USD] = Week1
FROM [DW_StagingDB].[ETL].[Transform_FactLaborBudget] BUDGET JOIN
[DW_StagingDB].[ETL].[Transform_FactLaborDollars] LABOR ON
Labor.Location_Code = Budget.Location_Code
JOIN [DW_DatamartDB]. [dbo].[DimDate] DATE ON
Date.FiscalWeekOfPeriod = Labor.FiscalWeekOfPeriod AND
Date.FiscalPeriodOfYear = Labor.FiscalPeriodOfYear
WHERE Labor.FiscalYear = CAST(SUBSTRING(DATE.Date_Code,1,4) AS NVARCHAR(50)) AND
Budget.FiscalYear = CAST(SUBSTRING(DATE.Date_Code,4,1) AS NVARCHAR(50)) AND
Date.FiscalWeekofYear = 1

Hi,
I am trying to write an update query to update rows in one table.
Structure of Table1:
SocialSecurityNumber Varchar(9) -- Primary Key
Name Varchar(30)
Structure of Table2 :
SocialSecurityNumber Varchar(9)
Name Varchar(30)
Table 1 contains:
Row1: "123456789" Sally
Row2: "999999999" Bill
Row3: "333333333" Alex
Table 2 contains:
Row1: "123456789" <NULL>
Row2: "123456789" <NULL>
Basically I want to update the name column in Table 2 (based on the SocialSecurityNumber column) so that after
the update Table 2 will contain:
Row1: "123456789" Sally
Row2: "123456789" Sally
------------------------------------------------------------
First I tried:
UPDATE Table2
INNER JOIN Table1 ON Table2.SocialSecurityNumber = Table1.SocialSecurityNumber
SET Table2.Name = Table1.Name
WHERE Table2.SocialSecurityNumber = Table1.SocialSecurityNumber
This works in Access but not it SQL Server 7.0.
------------------------------------------------------------
Then I tried:
UPDATE Table2
INNER JOIN Table1 ON Table2.SocialSecurityNumber = Table1.SocialSecurityNumber
SET Table2.Name = Table1.Name
Again this works in Access but not it SQL Server 7.0.
------------------------------------------------------------
Finally I tried:
UPDATE Table2, Table1
SET Table2.Name = Table1.Name
WHERE Table2.SocialSecurityNumber = Table1.SocialSecurityNumber
This also did not work.
------------------------------------------------------------
Is there any way to write this update statement without cursors?
Thanks.

I've got the following update statement:
UPDATE ISSUE_ACTIONS
SET BAE_FLAG = 2
WHERE IA_ISSUE_NO = 399
AND IA_SEQUENCE = 20
The fields BAE_FLAG, IA_ISSUE_NO, and IA_SEQUENCE are all of the type int.
When I run this code inside of my windows app (C#),
cmd3.CommandText = "UPDATE ISSUE_ACTIONS " +
"SET BAE_FLAG = 2 " +
"WHERE IA_ISSUE_NO = 437 " +
"AND IA_SEQUENCE = 13";
try
{
cmd3.ExecuteNonQuery();
}
catch (Exception e)
{
throw (e);
}
I get a timeout error:
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
The statement has been terminated.
But when I run the SAME statement from Query Analyzer, it executes without a problem.
Has anyone run into this issue before? How do I get around this?
The CommandTimeout property of cmd3 is set to the default because this is not a complex query and should not take more than .5 seconds to execute.

I have a situation where I want to update a column if and only if it is null.
UPDATE Employee
SET VEmployeeID = CASE WHEN E.VEmployeeID IS NULL
THEN ves.VEmployeeID
END
FROM Employee E
INNER JOIN VEmployeeStaging VES
ON E.EID= VES.EID
But what happens is when I run the procedure every other time I run it, it changes everything to null. The other times it puts the VEmployeeID in.
So what is happening is the times when it is not null (where it is not supposed to do anything) it puts a null in. The next time it works.

here is my code:
Dim cn As New System.Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("LocalSqlServer").ToString())
cn.Open()
Dim adapter1 As New System.Data.SqlClient.SqlDataAdapter()
adapter1.SelectCommand = New Data.SqlClient.SqlCommand("update aspnet_Membership_BasicAccess.Products
set id = '" & textid.Text & "', name = '" & textname.Text & "', price = '" & textprice.Text & "', description = '" &
textdescription.Text & "', count = '" & textcount.Text & "', pictureadd = '" & textpictureadd.Text & "', artist = '" &textartist.Text & "', catergory = '" & textcategory.text & "' where id = " & Request.Item("id") & ";", cn)
cn.Close()
Response.Redirect("database.aspx")
it posts and the page loads but the data is still the same in my datagrid. what could be wrong with this simple statement... i've tried testing the statement above with constant values of the correct type but i don't think that matters because the SqlCommand() accepts a string only anyways.. doesn't it?

The Folowing code is not working anymore. (500 error)
Set objRS = strSQL1.Execute
strSQL1 = "SELECT * FROM BannerRotor where BannerID=" & cstr(BannerID)
objRS.Open strSQL1, objConn , 2 , 3 , adCmdText
If not (objRS.BOF and objRS.EOF) Then
objRS.Fields("Exposures").Value =objRS.Fields("Exposures").Value + 1
objRS.update
End If
objRS.Close
The .execute Method works fine
strSQL1 = "UPDATE BannerRotor SET Exposures=Exposures+1 WHERE BannerID=" & cstr(BannerID)
objConn.Execute strSQL1

I am writing a pgm that attaches to a SQL Server database. I have an Add stored procedure and an Update stored procedure. The two are almost identical, except for a couple parameters. However, the Add function works and the Update does not. Can anyone see why? I can't seem to find what the problem is...
This was my test:
Dim cmd As New SqlCommand("pContact_Update", cn)
'Dim cmd As New SqlCommand("pContact_Add", cn)
Try
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add("@UserId", SqlDbType.VarChar).Value = UserId
cmd.Parameters.Add("@FirstName", SqlDbType.VarChar).Value = TextBox1.Text
[...etc more parameters...]
cmd.Parameters.Add("@Id", SqlDbType.VarChar).Value = ContactId
cn.Open()
cmd.ExecuteNonQuery()
Label1.Text = "done"
cn.Close()
Catch ex As Exception
Label1.Text = ex.Message
End Try
When I use the Add procedure, a record is added correctly and I receive the "done" message. When I use the Update procedure, the record is not updated, but I still receive the "done" message.
I have looked at the stored procedures and the syntax is correct according to SQL Server.
Please I would appreciate any advice...

I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.

i was tasked to created an UPDATE statement for 6 tables , i would like to update 4 columns within the 6 tables , they all contains the same column names. the table gets its information from the source table, however the data that is transferd to the 6 tables are sometimes incorrect , i need to write a UPDATE statement that will automatically correct the data. the Update statement should also contact a where clause
the columns are [No] , [Salesperson Code], [Country Code] and [Country Name]
i was thinking of doing
Update [tablename]
SET [No] =
CASE
WHEN [No] ='AF01' THEN 'Country Code' = 'ZA7' AND 'Country Name' = 'South Africa'
ELSE 'Null'
END
What is the best way to script this

It appears to update only the first qualifying row. The trace shows a row count of one when there are multiple qualifying rows in the table. This problem does not exist in JDBC 2000.

Any ideas why this line is bringing up just titles rather than titles and slogan:
dbsreq = "SELECT data_contents, data_style FROM content WHERE data_language = '" & siaith & "' AND data_type = 'title' AND 'slogan';"
(obviously it's all on one line in my code)
I don't understand why it brings up just 'title', not 'title' and 'slogan'?
Any ideas/fizes/suggestion would be greatfully appreciated.

I have a stored procedure that has an @Style parameter passed into it.
And down at the very bottom of the procedure it has this line:
And Style Like @Style
Now I realize that is not really valid, and I changed it to Style=@Style. But I'd like to understand WHY that isn't working as it was previously.
On our development box (single core X64) it works fine but on our multiple core X64 production box, this doesn't work.
Any ideas?
This is a MS SQL 2005 server we are talking to.

Hello,
I'm writing a fairly involved stored procedure. In this Stored Procedure, I have an update statement, followed by a select statement. The results of the select statement should be effected by the previous update statement, but its not. When the stored procedure is finish, the update statement seemed to have worked though, so it is working.
I suspect I need something, like a GO statement, but that doesnt seem to work for a stored procedure. Can anyone offer some assistance?

I have this statement buried in a sproc:
INSERT INTO PLAN_DEMAND ([YEAR], BOD_INDEX, SCEN_ID)
SELECT PLAN_SHIP.[YEAR], PLAN_SHIP.BOD_INDEX, 1
FROM PLAN_SHIP LEFT JOIN PLAN_DEMAND ON
PLAN_SHIP.[YEAR]=PLAN_DEMAND.[YEAR]
AND PLAN_SHIP.[BOD_INDEX]=PLAN_DEMAND.BOD_INDEX
WHERE PLAN_DEMAND.BOD_INDEX IS NULL
When I run the sproc in QA, the statements returns records to the grid, but does not insert them into the table. If I just copy the statement into QA and execute it, it works fine.
I'm sure it's something obvious (but not to me).
Any help would be much appreciated.

I followed an example using the AdventureWorks database to set up a simple messaging test on one database:
Code Block
-- We will use adventure works as the sample database
USE AdventureWorks
GO
-- First, we need to create a message type. Note that our message type is
-- very simple and allowed any type of content
CREATE MESSAGE TYPE JobRequest
VALIDATION = NONE
GO
-- Once the message type has been created, we need to create a contract
-- that specifies who can send what types of messages
CREATE CONTRACT JobRequestor
(JobRequest SENT BY INITIATOR)
GO
-- The communication is between two endpoints. Thus, we need two queues to
-- hold messages
CREATE QUEUE RequestorQueue
CREATE QUEUE ReceiverQueue
GO
-- Create the required services and bind them to be above created queues
CREATE SERVICE Requestor
ON QUEUE RequestorQueue
CREATE SERVICE Receiver
ON QUEUE ReceiverQueue (JobRequestor)
GO
-- At this point, we can begin the conversation between the two services by
-- sending messages
DECLARE @conversationHandle UNIQUEIDENTIFIER
DECLARE @message NVARCHAR(100)
BEGIN
BEGIN TRANSACTION;
BEGIN DIALOG @conversationHandle
FROM SERVICE Requestor
TO SERVICE 'Receiver'
ON CONTRACT JobRequestor
WITH ENCRYPTION=OFF, LIFETIME= 600;
-- Send a message on the conversation
SET @message = N'Hello, World';
SEND ON CONVERSATION @conversationHandle
MESSAGE TYPE JobRequest (@message)
COMMIT TRANSACTION
END
GO
-- Receive a message from the queue
RECEIVE CONVERT(NVARCHAR(max), message_body) AS message
FROM ReceiverQueue
-- Cleanup
DROP SERVICE Sender
DROP SERVICE Receiver
DROP QUEUE SenderQueue
DROP QUEUE ReceiverQueue
DROP CONTRACT HelloContract
DROP MESSAGE TYPE HelloMessage
GO
This all works fine but if I run the section that creates the message and then copy the RECEIVE section to a new query window and execute it, nothing is returned. If I run the RECEIVE section within the same query window it returns the 'Hello World' message as expected. I am new to Service Broker and so am assuming that I am missing something obvious!!

</SelectParameters>
</asp:SqlDataSource> However, when I click Edit, change something, and then Update it doesn't update the database. However, if I remove the DataField bindings and use the AutoGenerateRows feature it works fine.

I can't specify that for the Type property. Could that be the issue?thx

Hi,
I am trying to concatenate the columns (PrevEmp01, PrevEmp02, PrevEmp03, PrevEmp04, PrevEmp05) into column (ft) using trigger:
CREATE TRIGGER [tg_prevemp_ft_update] ON [tStaffDir_PrevEmp] FOR INSERT, UPDATEASUPDATE tStaffDir_PrevEmp SET ft = PrevEmp01 + ' ' + PrevEmp02 + ' ' + PrevEmp03 + ' ' + PrevEmp04 + ' ' + PrevEmp05
I would expect the (ft) column will be populated accordingly regardless if any of the columns are (Null).But the Trigger will only work when all the 5 columns are populated. If one of the column is (Null), the (ft) column will be (Null) too.Please advise. Many Thanks.

Can someone please tell me why in the bloody hell this isnt working? It ignores the WHERE VENDORID match portion and marks all instances of USERID match to TRUE. I've been banging my head for an hour... have I really forgotten basic sql???!!!!public static void UpdateVendor(VendorEvaluationEntity VEE)
{int vendorid = Convert.ToInt32(VEE.VendorevalVendor);
int userid = Convert.ToInt32(VEE.VendorevalUser);SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["VendorEvaluationConnectionString"].ConnectionString);
SqlCommand cmd = new SqlCommand("Update tblVendorUser set vendoruser_vendor_evaluated = 'true' where (vendoruser_vendor_id = @vendorid) and (vendoruser_user_id=@userid)", conn);SqlParameter pmvendorid = new SqlParameter();
SqlParameter pmuserid = new SqlParameter();pmvendorid.ParameterName = "@vendorid";pmvendorid.SqlDbType = SqlDbType.Int;
pmvendorid.Value = vendorid;
pmuserid.ParameterName = "@userid";pmuserid.SqlDbType = SqlDbType.Int;
pmuserid.Value = userid;
cmd.Parameters.Add(pmvendorid);
cmd.Parameters.Add(pmuserid);
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
}
