For Tableau, specify a value from 255 to 4000 that suits your environment.
The value specified for the String Describe Type connection option determines whether the String data type maps to the SQL_WVARCHAR or SQL_WLONGVARCHAR ODBC data types.
Max String Size replaces the Max Varchar Size connection option.
