"" : [1 (Q1_1) ] Data Type: Unicode string [DT_WSTR ? : (Conditional) (SSIS Expression) When comparing the expressions, the system applies the following conversion rules in the order listed: When the two expressions evaluate to the same data type, a comparison of that data type is performed. The data used for this example is shown below. An expression can contain any combination of variables, functions, operators, and columns from the transformation input. I am currently trying to do this with the derived column transformation in a data flow object. Drag Derived Column Transformation to Data Flow Pane and connect the Flat File Source to it.
