Update And Delete Statement Issues
Oct 7, 2007
I'm working on a address book where customers can add, edit and delete address book entries. For the life of me I can't figure out what I'm messing up with the Update and Delete statements of this feature. Can someone please help me.
Here's my code:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConflictDetection="CompareAllValues"

Hi AllgI have problem in using the SQLDataSource. When in VS 2005 I drag and drop the SQLDataSource onto my page and then add a GridView control.I bind the GridView control to the SQLDataSource control. But the problem is it does not generate the INSERT, UPDATE, and DELETE statements. The dialog box is inactive. The screenshots may help. please help me in this regard. I also tried it for Accesscontrol but the same problem. Sorry for my poor English!. thanks in advancehttp://img205.imagevenue.com/img.php?image=27550_1_122_203lo.JPGhttp://img139.a.com/img.php?image=28285_2_122_937lo.JPG

I have created a Dynamic Merge statement SCD2 Store procedure , which insert the records if no matches and if bbxkey matches from source table to destination table thne it updates old record as lateteverion 0 and insert new record with latest version 1.
I am getting below error when I ahve more than 1 bbxkey in my source table. How can I ignore this.
BBXkey is nothing but I am deriving by combining 2 columns.
Msg 8672, Level 16, State 1, Line 6
The MERGE statement attempted to UPDATE or DELETE the same row more than once. This happens when a target row matches more than one source row. A MERGE statement cannot UPDATE/DELETE the same row of the target table multiple times. Refine the ON clause to ensure a target row matches at most one source row, or use the GROUP BY clause to group the source rows.

I have a four tables called plandescription, plandetail and analysisdetail. The table plandescription has the columns DetailQuestionID which is the primary and identity column and a QuestionDescription column.
The table plandetail consists of the column PlanDetailID which the primary and identity column, DetailQuestionID which is the foreign key attribute of plandescription table and a planID column.
The third table analysisdetail consists of a analysisID which the primary and identity column, PlanDetailID which is the foreign key attribute of plandetail table and a scenario.
Below is the schema of the three tables
I have a two web form that will insert, update and delete data into these three tables in a two transaction. One web form will perform CRUD operations in plandescription and plandetail table. When the user inserts QuestionDescription and planid in this web form, I will insert the QuestionDescription Value in the plandescription table and will generate a DetailQuestionID value and this value is fed to the plandetail table with the planid. Here I will generate a PlanDetailID.
Once this transaction is done, I will show the second web form in which the user enters the scenario and this will be mapped with the plandescription using the PlanDetailID.
This schema cannot be changes as this is the client requirement. When I insert values I don’t have any problem. However when I update existing data, I need to delete existing PlanDetailID in the plandetail table and recreate PlanDetailID data for that DetailQuestionID and planID. This is because, the user will be adding or deleting a planID associated with the QuestionDescription.
Once I recreate PlanDetailID for that DetailQuestionID and planID, I need to update the old PlanDetailID with the new PlanDetailID in the third table analysisdetail for the associated analysisID.
I created a #Temp table called #DetailTable to insert the values analysisID, planid and old PlanDetailID and new PlanDetailID so that I can have them in update statement once I delete the data from plandetail table for that PlanDetailID.
Then I deleted the plandetailid from the plandetail table and recreate PlanDetailID for that DetailQuestionID. During my recreation I fetched the new PlanDetailID’s created into another temp table called #InsertedRows
After this I am running a while loop to update the temp table #DetailTable with the newly created PlanDetailID for the appropriate planID’s. The problem is here. When I have the same number of planID’s for example 2 planID’s 1,2 I will have only two old PlanDetailID and new PlanDetailID for that planID and analysisID.But When I add a new PlanID or remove a existing planID I am getting null value for that newly added or deleted planID. This is affecting my update statement of analysisdetail table as PlanDetailID cannot be null.
I tried to remove the Null value from the #DetailTable by running the update statement of analysis detail in a while loop however its not working.
DECLARE @categoryid INT = 8
DECLARE @DetailQuestionID INT = 1380
/*------- I need the query to run for the below three data.
Here i'm updating my planids that already exists in my database*/
DECLARE @planids VARCHAR(MAX) = '2,4,5'

I have 3 tables, with this relation:
tblChats.WebsiteID = tblWebsite.ID
tblWebsite.AccountID = tblAccount.ID
I need to delete rows within tblChats where tblChats.StartTime - GETDATE() < 180 and where they are apart of @AccountID. I have this select statement that works fine, but I am having trouble converting it to a delete statement:
SELECT * FROM tblChats c
LEFT JOIN tblWebsites sites ON sites.ID = c.WebsiteID
LEFT JOIN tblAccounts accounts on accounts.ID = sites.AccountID
WHERE accounts.ID = 16 AND GETDATE() - c.StartTime > 180

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.

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?

Hi,I would like to delete a record from a table on the condition that a corresponding ID is located in another table, ie. deleting an email message if the user ID is listed as a recipient in a recipient table etc. Here is my SQL statement: DELETE FROM id_email_message WHERE (id_message IN (SELECT id_message FROM recipients
WHERE id_user = 324) AND message.id_message_status = 2) OR (id_message IN
(SELECT id_message FROM message WHERE id_owner = 324 and id_message_status = 2)) The problem is the multiple select statements paired with the delete statement is too much overhead for the server and I always get a timeout server error (at least that's what I'm guessing, the error page and tracing isn't much helpful). Is there a more efficient way to do this?Thanks.Eitan

Hello there... I'm creating a ASP.net Web Application and storing all my data in SQL database.I'm trying to create a Stored Procedure to Delete info from a table:- I have 3 tables: A, B and C: A's primary key is aID and has no foreign key B's primary key is bID and has 1 foreign key: aID (linking this table to table A); C's primary key is cID and has 1 foreign key: bID (linking this table to table B);- As you can see, all 3 tables are linked (A to B and B to C)I want to be able to DELETE all info from C only by giving aID, is this possible in SQL? I can retrieve the info easily through a SELECT statement and using an INNER JOIN (*). I also know how to do solve this by coding it in C# but I'd have to create some unnecessary variables and more than 1 Stored Procedure when it's probably possible to do all in one!* SELECT cID FROM C INNER JOIN B ON B.bID = C.bIDWHERE A.aID= whateverIf anyone knows the solution to my problem, please don't hesitate :p Thanks,SuperJB

When does the DELETE statement physically deletes the records? For example, if I execute the DELETE statement and in the middle of the execution I understand that it is wrong. What will happen if I stop it? Will it delete the records partially? I think the deletion happens when the full statement is done but need an expert answer. Thank you.

Hello
I am trying to delete a row from one table and I expected it to also be removed from the subsequent child tables, linked via foreign and primary keys.
However, when I tried to delete a row in the first table I saw this error:
DELETE FROM [dbo].[Names_DB]WHERE [LName_Name]=N'andrews'
Error: Query(1/1) DELETE statement conflicted with COLUMN REFERENCE constraint 'FK_LName_Name'. The conflict occurred in database 'MainDB', table 'Category_A', column 'LName_Name'.
I went to the very last table in the sequence and I was able to delete the row without problems, but it did not effect any of the other tables.
Please advise.
I need to make many changes in these tables, should I use a trigger instead, if so what is the code to trigger each table? I am new to triggers.
Thanks
Regards
Lynn

Hey guys...
I am trying to tidy up my code a bit and have one SQL command (Sub class) to call when needing to insert, update, delete and select.
I have got one class I am testing with that delete from a table support_ticket and then calls RunSQL() again to delete the corresponding tickets in Support_Reply.
however it only seems to want to delete from one table at a time...as i commented out the first sql and it worked and the second fires...but if the first one is active it doesnt fire.
Do anyone on the forum know why this has happened?
Sub DeleteUserTicket(sender as Object, e as EventArgs)
Dim strSQL1 = "DELETE FROM Support_Ticket WHERE (TicketID = " & txtticketID & ")"
RunSQL(strSQL1)
strSQL1 = "DELETE FROM Support_Reply WHERE (TicketID = " & txtticketID & ")"
RunSQL(strSQL1)
End Sub
'One class to run the sql statements for the entire page this will reduce in repetitve code as well as reduce code size
Sub RunSQL(strSQL)
Dim objCmd As SqlCommand
Dim sqlConn = New SqlConnection(strConn)
objCmd = New SQLCommand(strSQL, sqlConn)
objCmd.Connection.Open()
'Check that the rows can be deleted if not then return a error.
Try
objCmd.ExecuteNonQuery()
response.redirect("ticketsystemtest2.aspx")
Message.InnerHtml = "<b>Ticket " & txtticketID & " Closed</b> <br/>"
Catch ex As SqlException
If ex.Number = 2627 Then
Message.InnerHtml = "ERROR: A record already exists with " _
& "the same primary key"
Else
Message.InnerHtml = "ERROR: Could not update record, please " _
& "ensure the fields are correctly filled out <br>" & ex.Message & " " & ex.Number
Message.Style("color") = "red"
End If
End Try
objCmd.Connection.Close()
sqlConn = nothing
objcmd = nothing
End Sub
cheers

Hi,
I've got a table with about 500 000 records and growing monthly by about 40 000 records
When I perform the following query:
DELETE from [myTable] WHERE Month = '07' AND Year='2005'
This query will take about 10 minutes to execute. Columns Month & Year are both indexed.
Surely MSSQL can't be this slow on only 500 000 records.
Must I do some other database optimization ???
Thanks

Hello, currently I have a query like this:
PHP Code:
SELECT *
FROM relations INNER JOIN
paths ON relations.path = paths.path_id
WHERE
(paths.links = '161') AND (relations.node1 = 162) OR
(paths.links = '161') AND (relations.node2 = 162) OR
(paths.links = '162') AND (relations.node1 = 161) OR
(paths.links = '162') AND (relations.node2 = 161) OR
(paths.links LIKE '162%') AND (relations.node1 = 161) OR
(paths.links LIKE '%162') AND (relations.node2 = 161) OR
(paths.links LIKE '161%') AND (relations.node1 = 162) OR
(paths.links LIKE '%161') AND (relations.node2 = 162) OR
(paths.links LIKE '%161;162%') OR
(paths.links LIKE '%162;161%')
ORDER BY relations.node1
Don't pay attention to the 161 and 162 things, is just test data, now my problem is that I want to transform that into a DELETE statement, but I can't find the right way to do it, so far I managed to do something like:
PHP Code:
DELETE relations
FROM relations INNER JOIN
paths ON relations.path = paths.path_id
WHERE
(paths.links = '161') AND (relations.node1 = 162) OR
(paths.links = '161') AND (relations.node2 = 162) OR
(paths.links = '162') AND (relations.node1 = 161) OR
(paths.links = '162') AND (relations.node2 = 161) OR
(paths.links LIKE '162%') AND (relations.node1 = 161) OR
(paths.links LIKE '%162') AND (relations.node2 = 161) OR
(paths.links LIKE '161%') AND (relations.node1 = 162) OR
(paths.links LIKE '%161') AND (relations.node2 = 162) OR
(paths.links LIKE '%161;162%') OR
(paths.links LIKE '%162;161%')
But that would delete only from the relations table and not from the paths table. I need to delete from both tables.
Can anyone help me please? Its kinda urgent.
Thansk!

Hi,
I need to delete the following records (from enrollment_fact):
SELECT
a."STU_SID",
a."SCHOOL_YEAR",
a."DATE_SID",
a."LOC_SID"
FROM "dbo"."ENROLLMENT_FEX2" b,
"dbo"."LOCATION_DIM" c
LEFT OUTER JOIN
"dbo"."ENROLLMENT_FACT" a
on c."LOC_SID" = a."LOC_SID"
WHERE
b."LOC_KEY" = c."LOC_KEY"
and
a."DATE_SID" between b."MIN_DATE" and b."MAX_DATE"
This is the approach (excuse the misuse of the concat function, but you get the idea)
DELETE FROM "dbo"."ENROLLMENT_FACT"
WHERE CONCAT (a."STU_SID", a."SCHOOL_YEAR", a."DATE_SID", a."LOC_SID")
IN (
SELECT DISTINCT CONCAT (a."STU_SID",
a."SCHOOL_YEAR",
a."DATE_SID",
a."LOC_SID"
)
FROM "dbo"."ENROLLMENT_FEX2" b,
"dbo"."LOCATION_DIM" c
LEFT OUTER JOIN "dbo"."ENROLLMENT_FACT" a
ON c."LOC_SID" = a."LOC_SID"
AND a."DATE_SID" BETWEEN b."MIN_DATE"
AND b."MAX_DATE")
comments? better way? (without using an sp)

I have a rather tricky SQL delete query I’m trying to perform, preferably without cursors. I have the following data set, where I want each of the first changes to the status.
IDStatus
1Good
2So-So
3So-So
4Bad
5Bad
6Bad
7Bad
8Bad
9So-So
10Good
So given the above data set I would want to delete the following IDs: 3, 5, 6, 7, and 8. As they not the first in order. The problem is that while I can get isolate and save first instance of each status (in this case 1, 2, and 4), I can’t get the what I want. Is there a SQL way of accomplishing this.

I have duplicate rows of data with the exact same data, for multiple sets of data.For example,
1 Fred Flintstone
1 Fred Flintstone
2 Barney Rubble
2 Barney Rubble
etc...
If I use the delete and where command, it will delete both rows and I want to keep one of them. I don't want to copy down each one and re insert as there are too many columns for each one and there are too many rows also.I was thinking of a delete row-number command in a where statement. but tried multiple forums and its not working.

Is it possible to create a function that deletes records from a table ?
CREATE FUNCTION F_TSImported_Delete()
returns int
as
Begin
delete from ts_imported
return 0
end
GO
This throws error like this:
Invalid use of side-effecting or time-dependent operator in 'DELETE' within a function.
