Script:列出没有主键或唯一索引的表-优快云博客

本文提供两个Oracle SQL脚本：一是用于查找缺少主键的表；二是用于查找没有唯一约束或唯一索引的表。这些脚本排除了系统schema，并帮助数据库管理员快速定位可能存在的数据完整性问题。

以下脚本可以用于列出数据库中没有主键的表，已排除了系统schema:

REM List tables with no primary key

SELECT owner, table_name
  FROM dba_tables
 WHERE 1 = 1
       AND owner NOT IN
              ('SYS',
               'SYSTEM',
               'SYSMAN',
               'EXFSYS',
               'WMSYS',
               'OLAPSYS',
               'OUTLN',
               'DBSNMP',
               'ORDSYS',
               'ORDPLUGINS',

               'CTXSYS',
               'AURORA$ORB$UNAUTHENTICATED',
               'XDB',

  FROM dba_constraints
 WHERE constraint_type = 'P'
       AND owner NOT IN
              ('SYS',

以下脚本可以用于列出数据库中没有唯一约束或索引的表，已排除了系统schema:
