SSIS query doesn't update in Execute Sql Task Editor but updates in sql server management studio

Question

Here is the script:

DECLARE @Filename varchar(10)
SET @Filename = 'TubeSta_cycle_log.txt'

UPDATE    Torque.LastUpdate
SET       LastUpdated = getDate()
WHERE     Station  = substring(@Filename,1,CHARINDEX('_', @FileName)-1)

The 'Execute SQL Task Editor' executes with NO errors but doesn't update the table.

Answer 1

Well I see a few possible issues with this.

DECLARE @Filename varchar(10)
SET @Filename = 'TubeSta_cycle_log.txt'

The value added to the parameter is TubeSta_cy so your filename is being truncated.

If you run in SSMS:

select substring(@Filename,1,CHARINDEX('_', @FileName)-1)

The result is TubeSta , do you have a record with that value?

It seems like you need to expand your varchar(50)
