记一次日终环境批量数据SQL优化

环境：阿里云EC2服务器/oracle 11.2.0.1

一天下午2点多，发现alert告警，看到一条SQL执行报01555错，具体如下所示：

![Image 1][]![Center][]

![Image 1][]

执行超过1831s，才执行完，结果查出来一共也就需要9w多数据，为何如此的慢

![Image 1][] ![Center 1][]

![Image 1][]

之后同事在一些表上添加了索引，勉强日终可以跑过去，但是还是比较慢

CREATE INDEX IDX\_F\_ACCINVESTBILL\_01 ON F\_ACCINVESTBILL("MANAGERID", "ACTUALPAYDATE");

CREATE INDEX IDX\_F\_ACCPLANCOLLECTRECEIPT\_01 ON F\_ACCPLANCOLLECTRECEIPT("AUDITDATE");

然后手动执行了一下这条添加过索引的SQL语句

select u.usercode, 
        
                u.username, 
        
                u.orgid,

可以看到执行 了143s，逻辑读106734311也就是1亿多逻辑读。

可见虽然添加索引优化以后，从1831s降到了143s， alert也不再 报01555错，但是资源消耗可以看到很高。

然后先尝试进行将标量子查询挪下来进行改写。改写SQL如下：

select u.usercode, 
        
                u.username,

                                       trunc(t.BUSINESSDATE, 'mm') then 
        
                                   trunc(t.BUSINESSDATE, 'd') - 6 
        
                                  else 
        
                                   trunc(t.BUSINESSDATE, 'mm') 
        
                                end begindate 
        
                           from f_vsmsysdate t) and d.BUSINESSDATE 
        
                  group by a1.MANAGERID, b1.proid) x, 
        
                (select a.proid, a.managerid, count(1) signcount 
        
                   FROM F_accinvestbill a,f_vsmsysdate d 
        
                  where a.ACTUALPAYDATE between 
        
                        (select case

                                       trunc(t.BUSINESSDATE, 'mm') then 
        
                                   trunc(t.BUSINESSDATE, 'd') - 6 
        
                                  else 
        
                                   trunc(t.BUSINESSDATE, 'mm') 
        
                                end begindate

          where u.id = r.userid 
        
            and u.id = f.userid 
        
            and f.proid = p.ID 
        
            and r.roleid = s.id 
        
            and s.rolecode = 'FX02' 
        
            and v.id = u.orgid 
        
            and u.validflag in ('0', '1') 
        
            and r.useflag = '1' 
        
            and p.PROTYPE in ('00', '01', '06') 
        
            and x.MANAGERID(+) = u.id 
        
            and x.proid(+) = f.proid 
        
            and y.proid(+) = f.proid 
        
            and u.id = y.managerid(+)

然而却报了如下错;

![Image 1][] ![Center 3][]

![Image 1][]

也就是说两个标量子查询对外关联了同一张表，SQL语句无法这么写，故而报错。

C:\\Users>oerr ora 1417

01417, 00000, "a table may be outer joined to at most one other table"

// \*Cause:  a.b (+) = b.b and a.c (+) = c.c is not allowed

// \*Action: Check that this is really what you want, then join b and c first

//          in a view.

然后无奈重新改写如下：

select v.usercode, 
         
                 v.username, 
         
                 v.orgid,

然后继续修改，索性直接把标量子查询全盘拿下来，原来的查询结果作为一张临时视图来看，修改SQL如下：
