On, Off

Off

When a connection is opened, the SQL Anywhere ODBC driver uses the setting of this option to determine how CHAR columns are described. If this option is set to Off (the default), then CHAR columns are described as SQL_VARCHAR. If this option is set to On, then CHAR columns are described as SQL_CHAR. VARCHAR columns are always described as SQL_VARCHAR.
