Great article. I was just about to send a very similar article for submission. Guess you beat me to it:)

I second that. The for each loops are a great tool. I use one with variables and script for looping through database backups on my main server to grab the latest dated ones and FTP them over to a secondary backup server (no I'm not really paranoid about losing data!)

Just came across your article and fine it very useful tools for me to learn sqlis. I have a problem with Execute SQL Task in the loop container:
Insert into tmpTlogFileList(FileName)values(@FileName):
Execute SQL Task: Executing the query "insert into tmpTlogFileList (FileName) values (@FileName)" failed with the following error: "Must declare the scalar variable "@FileName".".

Must I declare @Filename as nvarchar(128) from the sql statement?

thanks

Right-click your "Execute SQL Task". In the "Execute SQL Task Editor", go to Parameter Mapping. Add a parameter as follows:

Variable Name - User::varTLogFileName
Direction - Input
Data Type - String
Parameter Name - @FileName
Parameter Size: -1

Hope this is now clear. Best of luck!

Paul,

I get the same error...Here are a bit more detail on execute sql task:
General tab:
resultset: None
connectionType: OLE DB
connection: UserServerConnection
sqlsourceType: Direct input
sqlstatement: insert into tmpTLogFileList(FileName) values (@FileName)
bypassPrepare: True

The Parameter Mapping is same above as you mention, except
for Data Type - Nvarchar, I can't fine the dropdown for String.

I appreciate all you help thanks....

Error: 0xC002F210 at Execute SQL Task, Execute SQL Task: Executing the query "insert into tmpTLogFileList(FileName) values (@FileName)" failed with the following error: "Must declare the scalar variable "@FileName".". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

tran008,

I think you need to provide a bit more basic information about what you are trying to do. Where are you getting the @FileName parameter from anyway? My thoughts are that it should be declared as a User::[varname] in the for each loop and then this mapped across to the parameter in the SQL Task, but without knowing what it is you are trying to do it is hard to be of more assistance.

Best Regards
Terry

As an after thought - depending on what you wish to do of course, you may have to execute the sql statement as a variable. Out of curiosity I just put together a for each loop to save a series of .txt files into a table and this worked well by using a variable for the sql statement. Let me know if you want any further detail on this method.

Best Regards
Terry

thanks...I finally figure this out after long search.

OleDB...connection.

INSERT INTO tempTlogFileList
(FileName)
VALUES (?)

instead of
INSERT INTO tempTlogFileList
(FileName)
VALUES (@FileName)
