>From the documentation of the ResultSet interface: "For maximum portability, result set columns within each row should be read in left-to-right order, and each column should be read only once." http://java.sun.com/j2se/1.5.0/docs/api/java/sql/ResultSet.html The same is true in ODBC (and the associated SQL/CLI standard). Some JDBC and ODBC drivers let you access the columns in any order, but some do not. -- Len --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
