这篇文章主要介绍了Oracle中检查外键是否有索引的SQL脚本分享,本文给出了两个版本的脚本源码,一个查询所有用户,一个查询单用户,需要的朋友可以参考下

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(CNAME3, ',' || CNAME3, NULL) ||
?????? NVL2(CNAME4, ',' || CNAME4, NULL) ||
?????? NVL2(CNAME5, ',' || CNAME5, NULL) ||
?????? NVL2(CNAME6, ',' || CNAME6, NULL) ||
?????? NVL2(CNAME7, ',' || CNAME7, NULL) ||
?????? NVL2(CNAME8, ',' || CNAME8, NULL) COLUMNS
? FROM (SELECT B.TABLE_NAME,
?????????????? B.CONSTRAINT_NAME,
?????????????? MAX(DECODE(POSITION, 1, COLUMN_NAME, NULL)) CNAME1,
?????????????? MAX(DECODE(POSITION, 2, COLUMN_NAME, NULL)) CNAME2,
?????????????? MAX(DECODE(POSITION, 3, COLUMN_NAME, NULL)) CNAME3,
?????????????? MAX(DECODE(POSITION, 4, COLUMN_NAME, NULL)) CNAME4,
?????????????? MAX(DECODE(POSITION, 5, COLUMN_NAME, NULL)) CNAME5,
?????????????? MAX(DECODE(POSITION, 6, COLUMN_NAME, NULL)) CNAME6,
?????????????? MAX(DECODE(POSITION, 7, COLUMN_NAME, NULL)) CNAME7,
?????????????? MAX(DECODE(POSITION, 8, COLUMN_NAME, NULL)) CNAME8,
?????????????? COUNT(*) COL_CNT
????????? FROM (SELECT SUBSTR(TABLE_NAME, 1, 30) TABLE_NAME,
?????????????????????? SUBSTR(CONSTRAINT_NAME, 1, 30) CONSTRAINT_NAME,
?????????????????????? SUBSTR(COLUMN_NAME, 1, 30) COLUMN_NAME,
?????????????????????? POSITION
????????????????? FROM USER_CONS_COLUMNS) A,
?????????????? USER_CONSTRAINTS B
???????? WHERE A.CONSTRAINT_NAME = B.CONSTRAINT_NAME
?????????? AND B.CONSTRAINT_TYPE = 'R'
???????? GROUP BY B.TABLE_NAME, B.CONSTRAINT_NAME) CONS
?WHERE COL_CNT > ALL
?(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)
?????????? AND I.COLUMN_POSITION <= CONS.COL_CNT
???????? 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
COLUMN COLUMNS format a30 word_wrapped
COLUMN TABLE_NAME format a15 word_wrapped
COLUMN CONSTRAINT_NAME format a40 word_wrapped
SELECT OWNER,
???? TABLE_NAME,
?????? CONSTRAINT_NAME,
?????? CNAME1 || NVL2(CNAME2, ',' || CNAME2, NULL) ||
?????? NVL2(CNAME3, ',' || CNAME3, NULL) ||
?????? NVL2(CNAME4, ',' || CNAME4, NULL) ||
?????? NVL2(CNAME5, ',' || CNAME5, NULL) ||
?????? NVL2(CNAME6, ',' || CNAME6, NULL) ||
?????? NVL2(CNAME7, ',' || CNAME7, NULL) ||
?????? NVL2(CNAME8, ',' || CNAME8, NULL) COLUMNS
? FROM (SELECT B.OWNER,B.TABLE_NAME,
?????????????? B.CONSTRAINT_NAME,
?????????????? MAX(DECODE(POSITION, 1, COLUMN_NAME, NULL)) CNAME1,
?????????????? MAX(DECODE(POSITION, 2, COLUMN_NAME, NULL)) CNAME2,
?????????????? MAX(DECODE(POSITION, 3, COLUMN_NAME, NULL)) CNAME3,
?????????????? MAX(DECODE(POSITION, 4, COLUMN_NAME, NULL)) CNAME4,
?????????????? MAX(DECODE(POSITION, 5, COLUMN_NAME, NULL)) CNAME5,
?????????????? MAX(DECODE(POSITION, 6, COLUMN_NAME, NULL)) CNAME6,
?????????????? MAX(DECODE(POSITION, 7, COLUMN_NAME, NULL)) CNAME7,
?????????????? MAX(DECODE(POSITION, 8, COLUMN_NAME, NULL)) CNAME8,
?????????????? COUNT(*) COL_CNT
????????? FROM (SELECT SUBSTR(TABLE_NAME, 1, 30) TABLE_NAME,
?????????????????????? SUBSTR(CONSTRAINT_NAME, 1, 30) CONSTRAINT_NAME,
?????????????????????? SUBSTR(COLUMN_NAME, 1, 30) COLUMN_NAME,
?????????????????????? POSITION
????????????????? FROM DBA_CONS_COLUMNS WHERE OWNER NOT IN ('SYS','SYSTEM','SYSMAN','HR','OE','EXFSYS','DBSNMP','MDSYS','OLAPSYS','SCOTT','EXFSYS','SH','PM','CTXSYS')) A,
?????????????? DBA_CONSTRAINTS B
???????? WHERE A.CONSTRAINT_NAME = B.CONSTRAINT_NAME
?????????? AND B.CONSTRAINT_TYPE = 'R'
???????? GROUP BY B.OWNER,B.TABLE_NAME, B.CONSTRAINT_NAME) CONS
?WHERE COL_CNT > ALL
?(SELECT COUNT(*)
????????? FROM DBA_IND_COLUMNS I
???????? WHERE I.TABLE_NAME = CONS.TABLE_NAME AND I.TABLE_OWNER=CONS.OWNER
?????????? AND I.COLUMN_NAME IN (CNAME1, CNAME2, CNAME3, CNAME4, CNAME5,
??????????????? CNAME6, CNAME7, CNAME8)
?????????? AND I.COLUMN_POSITION <= CONS.COL_CNT
???????? GROUP BY I.INDEX_NAME)
