获得执行计划方法六-dbms_xplan.diskplay_cursor

当我们知道一个SQL语句的sql_id后，可以通过使用dbms_xplan.diskplay_cursor方法来获取执行计划。
FUNCTION DISPLAY_CURSOR RETURNS DBMS_XPLAN_TYPE_TABLE
 Argument Name                  Type                    In/Out Default?
 ------------------------------ ----------------------- ------ --------
 SQL_ID                         VARCHAR2                IN     DEFAULT
 CURSOR_CHILD_NO                NUMBER(38)              IN     DEFAULT
 FORMAT                         VARCHAR2                IN     DEFAULT
