dbms_xplan.display_* 能按照 plan_hash_value 只有 display_awr 方法，如果这个SQL PLAN 刚刚生成，没有写入到AWR怎么办呢？
可以将 V$SQL_PLAN 的数据 LOAD 进 PLAN_TABLE 后进行展现：
DELETE FROM plan_table; insert into plan_table( statement_id ,PLAN_ID ,timestamp ,REMARKS ,OPERATION ,OPTIONS ,OBJECT_NODE ,OBJECT_OWNER ,OBJECT_NAME ,OBJECT_ALIAS ,OBJECT_INSTANCE ,OBJECT_TYPE ,OPTIMIZER ,SEARCH_COLUMNS ,ID ,PARENT_ID ,DEPTH ,POSITION ,COST ,CARDINALITY ,BYTES ,OTHER_TAG ,PARTITION_START ,PARTITION_STOP ,PARTITION_ID ,OTHER ,OTHER_XML ,DISTRIBUTION ,CPU_COST ,IO_COST ,TEMP_SPACE ,ACCESS_PREDICATES ,FILTER_PREDICATES ,PROJECTION ,TIME ,QBLOCK_NAME ) SELECT ‘PLAN_‘||PLAN_HASH_VALUE AS statement_id , 0 PLAN_ID ,SYSDATE timestamp ,REMARKS ,OPERATION ,OPTIONS ,OBJECT_NODE ,OBJECT_OWNER ,OBJECT_NAME ,OBJECT_ALIAS ,0 OBJECT_INSTANCE ,OBJECT_TYPE ,OPTIMIZER ,SEARCH_COLUMNS ,ID ,PARENT_ID ,DEPTH ,POSITION ,COST ,CARDINALITY ,BYTES ,OTHER_TAG ,PARTITION_START ,PARTITION_STOP ,PARTITION_ID ,OTHER ,OTHER_XML ,DISTRIBUTION ,CPU_COST ,IO_COST ,TEMP_SPACE ,ACCESS_PREDICATES ,FILTER_PREDICATES ,PROJECTION ,TIME ,QBLOCK_NAME FROM v$sql_plan WHERE PLAN_HASH_VALUE=‘&plan_hash_value‘ AND ADDRESS=(SELECT MAX(ADDRESS) FROM V$SQL_PLAN WHERE PLAN_HASH_VALUE=‘&plan_hash_value‘); SELECT * FROM TABLE(dbms_xplan.display(‘plan_table‘, ‘PLAN_‘||‘&plan_hash_value‘));
使用 dbms_xplan.display 按照 plan_hash_value 查执行计划的方法
