    Question:

    Is there any way I can change a T-SQL query in a Lookup component during runtime?

     

    Answer:

    1. Create a package scope variable "SQLVariable", change its type to string.

    2. Open the Lookup transformation, type a default SQL clause for it.

    3. Select the data flow task that includes the Lookup and go to its properties. Click on the ellipsis (…) against Expressions, use the expression "@[User::SQLVariable]" for [LookupName].[SqlCommand] property.

     Then you can dynamically change the SQL clause for the Lookup by modifying the value of the variable "SQLVariable".
