帮助优化SQL查询

Question

我有一个巨大的查询,这些年来逐渐增长,所有的iv都是为了满足增长而增加子程序.我现在的问题是这个查询大约需要3分钟才能运行.有人可以帮我优化这个查询

正如你可以看到这两个子程序是相同的,唯一的区别是select语句的总和.有没有办法我只能运行其中一个子程序来查找总和？

我显示了完整的查询,请有人帮助我吗？

确定 - 这样的事情:

SELECT ENTRY_1.AGE, ENTRY_1.REP_CODE,CONTACT_1.NAME, ENTRY_1.GOODS,
           sum((d2.total_goods-d2.total_cost)*et2.sign) 
           , sum((d2.total_goods)*et2.sign) 
.
.
. CODE TAKEN OUT
.
.
    FROM 
            detail d2 
            join entry e2 on d2.entry_id=e2.entry_id 
            join entry_type et2 on et2.entry_type=e2.entry_type 
            join rep r2 on e2.rep_code=r2.rep_code 
            join contact c2 on r2.contact_id=c2.contact_id 
            where ((d2.detail_type = 'O' and d2.charged_qty<d2.qty 
            and d2.nocharge_qty=0) 
            or (d2.detail_type = 'N' and e2.entry_type in('SINV','SCRN','DREC','DSRF'))
            or (( e2.entry_type = 'SJIN' ) and ( d2.total_goods = 0 ))) 
            and c2.contact_id=contact_1.contact_id 
            and (e2.year_num=entry_1.year_num and e2.period_num=entry_1.period_num))      MTD_GP
, ENTRY ENTRY_1 INNER JOIN REP REP_1 ON
         (REP_1.REP_CODE = ENTRY_1.REP_CODE)
          INNER JOIN CONTACT CONTACT_1 ON
         (CONTACT_1.CONTACT_ID = REP_1.CONTACT_ID)
    WHERE ( ENTRY_1.ENTRY_TYPE = 'SJOB' )
           AND ( ENTRY_1.AGE = 0 )

当然,这个想法是你将连接移动到下面 - 将它们从SELECT子句中取出并将它们(一次)放入FROM和WHERE子句中. - 我做的剪切和粘贴不是很正确,但你明白了(你也没有提供完整的查询以实际用作基础)
