Trigger With Exec Statement Blocking Execution Of Triggering Cmd?
Jul 20, 2005
I have a trigger on a table. I am trying to dynamically log the
changed fields on the table to another table, so I am iterating
through the bits in COLUMNS_UPDATED() to find what's changed, and
getting the column name programatically. This is all working fine.
If I do a regular insert command in my trigger then everything works
fine. However, since I want to retrieve data from the column name
which I got programatically from the inserted and deleted tables (to
get the old and new values) I wanted to do something like this:
insert into auditTransactionLog (TableName,
PrimaryKeyId,ColumnName,OldValue, NewValue, ActionType) EXEC( 'SELECT
(''cmContactInfo''), I.contactID,'''+ @colname+''', D.'+@colname+',
I.'+@colname+', '+@action+' FROM inserted I INNER JOIN Deleted D on
I.ContactId = D.ContactId')
The presence of this line of code appears to be preventing the
updating of the table with the trigger. Is there some reason why I
can't do the EXEC in the trigger? If I did it without EXEC it works
fine but I have no idea of getting at the D. and I. @colname columns
otherwise.
Thanks for any help!

I like to use the table "Inserted" within exec(), but it doesn't work because the scope is different. Does anyone have some sort of solution to this problem? The reason I am doing it this way is because I have a table consist of 200+ columns of bit types that contains permission information (The worest design i have ever seen!).
Code Snippet
--gather column names
declare @ScreenPermissions nvarchar(256)
declare c_Permission cursor
for
SELECT [name]
FROM syscolumns
WHERE id = (
SELECT id FROM sysobjects
WHERE type = 'U'
AND [NAME] = 'ScreenPermissions'
)
and [name] like 'Allow%'
open c_Permission
fetch next from c_Permission
into @ScreenPermissions
while @@fetch_status = 0
begin
exec('INSERT INTO EmployeeInRoles (EmployeeID, RoleID) ' +
'select i.EmployeeID, r.RoleID ' +
'from inserted as i ' +
' inner join ScreenPermissions AS sp on sp.EmployeeID = i.EmployeeID and sp.' + @ScreenPermissions + ' = 1 ' +
' inner join Roles AS r on r.LoweredRoleName = Lower(' + '''' + @ScreenPermissions + '''' + ')' )
fetch next from c_Permission
into @ScreenPermissions
end
close c_Permission
DEALLOCATE c_Permission

Hi, I am facing a problem here. I am trying to make a stored procedure which accepts an input. The input is a table name within the database. The procedure itself then will make an after update trigger for the table. The purpose of making this stored procedure is because the table keeps changing (columns can be added or deleted) and I don't want to make the trigger manually everytime the table changes, instead I want to execute the stored procedure by passing the table's name and the procedure will create the trigger for me. The problem is sql server 2005 has limited the length of any variable to 8000. The create trigger statement can be longer than that. So using a variable to store the create trigger statement and then executing that variable is not an option. That is why I have inserted the statement to be executed into a column in a temp table. Now how do I execute that statement? I have tried this:
EXEC(SELECT QRY FROM temp_Update)
Qry is the column name which holds the create trigger statement. temp_Update is the temporary table. But if I run it, it will give this error:
Msg 156, Level 15, State 1, Line 123Incorrect syntax near the keyword 'SELECT'.Msg 102, Level 15, State 1, Line 123Incorrect syntax near ')'.
Can anybody tell me how to execute a query which is place in a column in a table? If we can't do this, then what is the workaround, maybe how to have a variable that can hold more than 8000 characters? Any suggestion is greatly appreciate it. Thanks.

Hello,
I need to get the count into a local variable:
Select @SQL = 'Select ' + @TotalRowCount + ' = Count(*) )' + ' From ' + @TableName + ' Where ' + @WhereClause
Exec(@SQL)
It complains about ‘…. Integer…’, but even if I use a varchar parm and convert Count to varchar in the sql statement, it still does not work. It does not like the = , or so it says.
Any help greatly appreciated,
Judith

Hi!
Is it possible to call proc with parameter in openrowset?:
declare @str varchar(100);
select @str = 'EXEC SP_HELPTEXT ''createReport''';
select * from
OPENROWSET('SQLNCLI','Server=localhost;Trusted_Connection=yes;', @str)
AS a;
Incorrect syntax near '@str'.
------------------
select * from
OPENROWSET('SQLNCLI','Server=localhost;Trusted_Connection=yes;', 'EXEC
SP_HELPTEXT ''createReport''') AS a;
Msg 7357, Level 16, State 2, Line 1
Cannot process the object "EXEC SP_HELPTEXT 'createReport'". The OLE
DB provider "SQLNCLI" for linked server "(null)" indicates that either
the object has no columns or the current user does not have
permissions on that object.
Best regards

Hi
I've used a temporary table in the stored procedure
I've created it as DECLARE @Temp TABLE (id INT)
in select clause I've used this temp table through the joins..
But I've also used a varchar variable to store my criteria...
which I'm building in the stored procedure
so inorder to use it in the where clause I used
EXEC ('SELECT ....................
FROM @Temp T
LEFT OUTER JOIN ...
LEFT OUTER JOIN ...
WHERE ' + @Criteria )
Unfortunately this is not working.
Giving the errror
Must declare the variable '@TempT'.
I had to use Temporary table using #, which I feel is really waste of memory...
Is there a way by which I can use my Table variable in the EXEC statement.
Thanks In advance

Hi,
I have written a stored proc to bulk insert the data from a data file.
I have a requirement that i need to insert the data into a table of which the name is not known. I mean to say that the table name will be passed as a parameter to the stored proc. And also i need to insert the date that will also be passed as the parameter to the stored proc
The follwing statement works fine if i give the table name directly in the query
Code Snippet
DECLARE @LastUpdate varchar(20)
SET @LastUpdate = 'Dec 11 2007 1:20AM'
INSERT INTO Category
SELECT MSISDN, @LastUpdate FROM OPENROWSET( BULK '\remotemachinedatafile.txt',
FORMATFILE = '\remotemachineFormatFile.fmt',
FIRSTROW = 2) AS a
To satisfy my requirement ( i.e passing the table name dynamically , and the date) , i have formed the query string ( exact one as above ) and passing it to EXEC statement. But its failing as explained below
Code Snippet
@Category - Will be passed as a parameter to the stored proc
DECLARE @vsBulkSQL VARCHAR(MAX)
DECLARE @LastUpdate varchar(20)
SET @LastUpdate = 'Dec 11 2007 1:20AM'
SELECT @vsBulkSQL ='INSERT INTO '+ @Category + ' SELECT MSISDN, ''' + @LastUpdate +''' FROM OPENROWSET ' + '( BULK ' + '''' + '\remotemachinedatafile.txt'+ ''''+ ' ,' +
+ ' FORMATFILE ' + '=' + ''''+ '\remotemachineFormatFile.fmt'+ ''''+ ',' +
' FIRSTROW ' + '=' + '2' + ')' + ' AS a'
Print @vsBulkSQL - This prints the folliwing statement
INSERT INTO Category SELECT MSISDN, 'Dec 11 2007 1:20AM' FROM OPENROWSET ( BULK '\remotemachineDataFile.txt' , FORMATFILE ='\remotemachineFormatFile.fmt', FIRSTROW =2) AS a
Exec @vsBulkSQL - This statement gives the following error
The name 'INSERT INTO Sports SELECT MSISDN, 'Dec 11 2007 1:20AM' FROM OPENROWSET ( BULK '\remotemachineSecond.txt' , FORMATFILE ='\remotemachineFormatFile.fmt', FIRSTROW =2) AS a' is not a valid identifier.
Can any one please point out where am i doing wrong? Or do i need to do anything else to achive the same

How do I use a @variable to hold on value return from an exec ('string command') statement.
Example for:
declare @OldID int
declare @cmd varchar(255)
declare @db varchar(25)
declare @OldOwner varchar(25)
set @db = 'DBNAME'
set @OldOwner = 'USERNAME'
select @cmd = 'select uid from ' + ltrim(rtrim(@db))'..sysusers where name = ' + "'" + ltrim(rtrim(@OldOwner)) + "'"
exec (@cmd)
How can I use @OldID to hold on UID return from this statement.
When I try use:
select @cmd = 'select @OldID = uid from ' + ltrim(rtrim(@db))'..sysusers where name = ' + "'" + ltrim(rtrim(@OldOwner)) + "'"
then I'm getting a error message: @OldID not declare.

Hello,
Is there a way to trigger the execution of a procedure when a database is created ? We're using this 3rd party system in which you only specify the database server. Whenever the users create a new "Storage Area", the system actually creates a new database.
I need to handle backups for that system so I want to create a procedure that will generate a backup device and backup jobs automatically whenever a database is created.
I will also need 2 procedures to handle database renaming and deletion. I searched around but can't find a way to trigger the execution of my procedures.
