Oracle中检查外键是否有索引的SQL脚本分享


复制代码 代码如下:

COLUMN COLUMNS format a30 word_wrapped
COLUMN tablename format a15 word_wrapped
COLUMN constraint_name format a15 word_wrapped
SELECT TABLE_NAME,
       CONSTRAINT_NAME,
       CNAME1 || NVL2(CNAME2, ',' || CNAME2, NULL) ||

       NVL2(CNAME5, ',' || CNAME5, NULL) ||
       NVL2(CNAME6, ',' || CNAME6, NULL) ||
       NVL2(CNAME7, ',' || CNAME7, NULL) ||
       NVL2(CNAME8, ',' || CNAME8, NULL) COLUMNS
  FROM (SELECT B.TABLE_NAME,

               USER_CONSTRAINTS B

         GROUP BY B.TABLE_NAME, B.CONSTRAINT_NAME) CONS

 (SELECT COUNT(*)
          FROM USER_IND_COLUMNS I
         WHERE I.TABLE_NAME = CONS.TABLE_NAME
           AND I.COLUMN_NAME IN (CNAME1, CNAME2, CNAME3, CNAME4, CNAME5,
                CNAME6, CNAME7, CNAME8)

         GROUP BY I.INDEX_NAME)

在上面的基础上修改了一下,可以检查所有的用户。
复制代码 代码如下:

SET linesize 400;
COLUMN OWNER format a10 word_wrapped
