Syntax for WQL Source Query in SSIS Variable
Posted on 2011-03-08
I've got an SSIS package that watches for XML files in a specific folder. The package works when I enter the WQL Query directly into the task editor, but I can't get it to work using the same query as a variable. This must be a syntax issue but I haven't been able to find any examples of creating this kind of query in a variable. The query I'm typing in directly is:
Select * From __InstanceCreationEvent Within 10 Where TargetInstance ISA 'Cim_DataFile' And TargetInstance.Drive = 'C:' And TargetInstance.Path = '\\Data\\' And TargetInstance.Extension = 'xml'
When I tried to set this same query as the expression of a variable and evaluated the expression, I got an error like "...unrecognized token: select". So then i enclosed the whole string in double quotes. It evaluated okay, but when I ran the package in Design mode I got the error "unparseable query."
The scope of the variable is the package. I have 'evaluate as expression' set to True. The data type of the variable is String. If i enter the query without the quotes into the WMI Tester it succeeds and if I enter the query with the quotes i get the same error = unparseable query.
My ultimate goal is to replace the 'C:' and the '\\Data\\' with variables that are set per configuration. I tried that first and now I'm stepping back to get any query to work as a variable.
Can someone help me understand how this WQL query needs to look when the WQL Source Query Type is Variable?
