SQL_SET_CURRENT_CURSOR_STMT¶

Applies to: ORAFlex SQLFlex MYSQLFlex PGFlex DB2Flex

This command is used to open a cursor to be used for an SQl statement. The cursor must be created using the SQL_OPEN_CURSOR_STMT, but once it has been created, this command can easily switch between cursors as desired. Optionally a different server can be specified for each cursor by passing the server name to this command as well. If no server is specified, the current server will be used. Note that it is important to close all cursors at the end using SQL_CLOSE_CURSOR_STMT.
