- The number of variables in the RESULT list must match the number of the SELECT list items. Automatic data type conversion
is performed where possible if data types do not match.
- The RESULT clause is part of the CREATE PROCEDURE statement, and does not have a command delimiter.
- The names of the SELECT list items do not need to match those of the RESULT list.
- When testing this procedure, Interactive SQL displays only the first result set by default. You can configure Interactive
SQL to display more than one result set by setting the Show Multiple Result Sets option on the Results tab of the Options window.
