SSIS Lookup by NVarChar(Max) Column

Question

I want to get id from target table by lookup with NVarChar(Max) column in target table and NVarChar(20) column in source table. But raise error Cannot map the lookup colum

Answer 1

you cant:

The join can be a composite join, which means that you can join multiple columns in the transformation input to columns in the reference dataset. The transformation supports join columns with any data type, except for DT_R4, DT_R8, DT_TEXT, DT_NTEXT, or DT_IMAGE

are you sure you are using the component correctly? You usually lookup by ID to get the text. Can you give more details?
