ODBC error...please help

["Radim Klasek" <radim@klasek.org>]

Does anybody know, what does it mean:

SQL error: [Microsoft][ODBC Visual FoxPro Driver]File 'datum_format.prg' does not exist., SQL state S0002 in SQLExecDirect 

I'm using DATUM_FORMAT function in SQL command and this error is shown.

Thank you, Radim
