I have created an Access append query that extracts data from an external database (ODBC connection to Sybase database). The table to which I want to append the records has a Y/N field for which I have written a data validation rule to accept text values of Y or N from a six-position text field in the extracted data file, but Access won't let me do it. I get a type conversion failure message when I try. Is it possible to do this? If so, can you point me in the right direction? Thanks in advance.
