sql语句因语句太长或者太复杂

select a.*, PUR_CONT_LIST_CONTRACT.PUR_CONT_VERIFY_NO from
(SELECT PUR_CONT_BASE_INFO.* FROM PUR_CONT_BASE_INFO PUR_CONT_BASE_INFO LEFT JOIN (
SELECT PM.USABLE_STATUS USABLE_STATUSS, PM.PROJ_NO, PM.PUR_CONT_BASE_INFO_ID PUR_CONT_BASE_INFO_IDS FROM V_PUR_CONT_LIST_MATE_ALL PM
WHERE PM.USABLE_STATUS='1') M ON PUR_CONT_BASE_INFO.PUR_CONT_BASE_INFO_ID = M.PUR_CONT_BASE_INFO_IDS
WHERE PUR_CONT_BASE_INFO.USABLE_STATUS = '1' AND PUR_CONT_BASE_INFO.IS_HISTORY_VERSION <> '1' AND 1=1 AND (M.PROJ_NO = 'ZEC13BA0B00002.121001') AND PUR_CONT_BASE_INFO_ID in (
( select PUR_CONT_BASE_INFO_ID from PUR_CONT_BASE_INFO q where USABLE_STATUS='1' and q.PUR_MANAGER_CODE like '109910040000000000100001000010000[1,3,4,5,6,7]%' or q.PUR_MANAGER_CODE like '1099100400000000001000010000[2,3,4,5]%' UNION ALL SELECT PUR_CONT_BASE_INFO_ID FROM PUR_CONT_BASE_INFO ) ) AND ((AUDIT_STATE='003' and CONT_STATE IN ('001','002') )
or (CONT_STATE IN ('001','002','007','008','011','004'))) ) a left outer join PUR_CONT_LIST_CONTRACT on a.PUR_CONT_BASE_INFO_ID= PUR_CONT_LIST_CONTRACT.PUR_CONT_BASE_INFO_ID ORDER BY a.CREATE_DATE DESC, a.CONT_STATE asc
此为sql语句，我在模糊查询的时候报错，提出来sql，DB2提示我 -101 54001 SQL语句超出了已确定的DB2限制：例如，表的数目太多，语句中的字节太多 ，，我到DBA上

没人么

建议你把in关联查询改为inner join 关联查询

嗯呢 我试试 谢谢

建议楼主将经常查询的关联表做成视图

[tcmakebest]

这不是 MSSQLServer 啊？如果是的话这么点根本不长的。 建立把多余的空格去去掉吧。
