MDAC 2.5 SDK - ODBC Desktop Database Drivers
When the Text driver is used, a new table is created using the format specified in Odbcinst.ini. If not specified, tables are created in CSVDELIMITED format. By default, INTEGER columns default to 11 characters and FLOAT columns default to 22 characters. DATE columns use the YYYY-MM-DD format. CHAR and LONGCHAR columns are the width specified in the CREATE statement.
