oracleのdba_tablesからテーブル名をフェッチするクエリ

Question

dba_tab_statisticsでjoinを使用してdba_tablesからテーブル名をフェッチしたいとします。

select table_name 
from dba_tables a, 
    dba_tab_statistics b 
where a.owner like 'Owner' and a.table_name not like '%TMP' 
    and a.LAST_ANALYZED IS NOT NULL and a.table_name = b.table_name 
    and b.stattype_locked IS NULL; 

このクエリでは、個別のテーブル名はありません。どのような変更が必要ですか？

Answer 1

使用それらのいずれか：

SELECT a.table_name 
    FROM dba_tables a, 
     dba_tab_statistics b 
WHERE  a.owner LIKE 'Owner' 
     AND a.table_name NOT LIKE '%TMP' 
     AND a.LAST_ANALYZED IS NOT NULL 
     AND a.table_name = b.table_name 
     AND b.stattype_locked IS NULL 
group by a.table_name ; 

または

SELECT DISTINCT a.table_name 
    FROM dba_tables a, 
     dba_tab_statistics b 
WHERE  a.owner LIKE 'Owner' 
     AND a.table_name NOT LIKE '%TMP' 
     AND a.LAST_ANALYZED IS NOT NULL 
     AND a.table_name = b.table_name 
     AND b.stattype_locked IS NULL ;

別の解決策：

SELECT table_name 
    FROM dba_tables a 
WHERE owner LIKE 'Owner' 
    AND table_name NOT LIKE '%TMP' 
    AND LAST_ANALYZED IS NOT NULL 
    AND exists (SELECT 0 
       FROM dba_tab_statistics b 
       WHERE a.table_name = b.table_name 
       AND b.stattype_locked IS NULL);
