Freeing a Save Set

A save-set structure has a memory duration of PER_STMT_EXEC. Therefore, a save-set structure remains active until one of the following events occurs:

• The mi_save_set_destroy( ) function frees the save-set structure.
• The end of the current SQL statement is reached.
• The mi_close( ) function closes the current connection.

To conserve resources, use the mi_save_set_destroy( ) function to explicitly deallocate the save set once your DataBlade API module no longer needs it. The mi_save_set_destroy( ) function is the destructor function for a save-set structure. It frees the save-set structure and any resources that are associated with it.
