Identifier of an opened cursor, get by calling the wb_exec or wb_psql_execute function.


Popis

This function returns the number of rows in the opened cursor. It is not recommended to use this function for cursors with many records, since a call to this function evaluates the entire cursor, which may take a very long time.
