Anyway, you need to add a Data Conversion between the Source and the Lookup, and convert the column to DT_STR. In my case, because I want the output column name to be EmployerPAYEReference, I changed the original CAST in the Source to name the column INP_EmployerPAYEReference, and then set the converted column name to EmployerPAYEReference.

Feb 8, 2016 · I initially thought a Lookup transformation would be appropriate but I cannot use Full Cache because it attempts to load 350M rows in the cache! If I use No Cache, the process of looking up just 10,000 rows is horrendously slow (even though the …
