I'm trying to export some data from SQL SERVER to EXCEL, with SSIS, and got error on all columns like
[Excel Destination [2]] Error: Column "Contact Id" cannot convert between unicode and non-unicode string data types.
I tried to change data type in the OLE DB Source to be 'Unicode string [DT_WSTR]' or 'Unicode string [DT_STR]', but I get same error no matter which one I use.
