I have the following SQL statement as source in my Transform Data Task...
select * from dbo.BWR_GETINFO_RESULTS where cFileId = ?

and in the DTS Package Properties, my input global variable is assigned like this...
name is fileid
type is string
value is {4EA8FB8B-09FB-43A5-99C0-B767C73C3D30}

also in the Parameters Mapping of the Transform Data Task...
the Parameter 1 is set to fileid

Everything looks fine but when I click on the preview button I got this...
Error Source : Microsoft OLE DB Provider for SQL Server
Error Description : No value given for one or more required parameters.

It seems the global variable is ignored by the SQL execution.
Someone can explain the cause and an other way to do?
Thank you!
