最近在忙着优化集团公司的一个报表。优化完成后,报表查询速度由从半小时以上(甚至查不出)到秒查的质变。从修改 SQL 查询语句逻辑到决定创建存储过程实现,花了我 3 天多的时间,在此总结一下,希望对朋友们有帮助。
数据背景
不多说,直接贴西门子中国的开发人员在我司开发的 SSRS 报表中的 SQL 语句:
select distinct b.MaterialID as matl_def_id, c.Descript, case when right(b.MESOrderID, 12) < '001000000000' then right(b.MESOrderID, 9)
else right(b.MESOrderID, 12) end as pom_order_id, a.LotName, a.SourceLotName as ComLot,
e.DefID as ComMaterials, e.Descript as ComMatDes, d.VendorID, d.DateCode,d.SNNote, b.OnPlantID,a.SNCUST
from
(
select m.lotname, m.sourcelotname, m.opetypeid, m.OperationDate,n.SNCUST from View1 m
left join co_sn_link_customer as n on n.SNMes=m.LotName
where
( m.LotName in (select val from fn_String_To_Table(@sn,',',1)) or (@sn) = '') and
( m.sourcelotname in (select val from fn_String_To_Table(@BatchID,',',1)) or (@BatchID) = '')
and (n.SNCust like '%'+ @SN_ext + '%' or (@SN_ext)='')
) a
left join
(
select * from Table1 where SNType = 'IntSN'
and SNRuleName = 'ProductSNRule'
and OnPlantID=@OnPlant
) b on b.SN = a.LotName
inner join MMdefinitions as c on c.DefID = b.MaterialID
left join Table1 as d on d.SN = a.SourceLotName
inner join MMDefinitions as e on e.DefID = d.MaterialID
where not exists (
select distinct LotName, SourceLotName from ELCV_ASSEMBLE_OPS
where LotName = a.SourceLotName and SourceLotName = a.LotName
)
and (d.DateCode in (select val from fn_String_To_Table(@DCode,',',1)) or (@DCode) = '')
and (d.SNNote like '%'+@SNNote+'%' or (@SNNote) = '')
and ((case when right(b.MESOrderID, 12) < '001000000000' then right(b.MESOrderID, 9)
else right(b.MESOrderID, 12) end) in (select val from fn_String_To_Table(@order_id,',',1)) or (@order_id) = '')
and (e.DefID in (select val from fn_String_To_Table(@comdef,',',1)) or (@comdef) = '')
--View1是一个嵌套两层的视图(出于保密性,实际名称可能不同),里面有一张上亿数据的表和几张千万级数据的表做左连接查询
--Table1是一个数据记录超过1500万的表
探索和误区
对原 SQL 语句的分析
查询语句的 where 条件,有大量 @var in … or (@var =”) 的片段。
where 条件有 like ‘%’+@var+’%’。
where 条件有 case … end 函数。
多次连接同一表查询,另外使用本身已嵌套的视图表,是不是必须,是否可替代?
SQL 语句有号,视图中也有号出现。
优化设计
以此类推,可以建立多个临时表,将查询条件汇总。
![](https://filescdn.proginn.com/b97b6db1124f2d876a7d1daf06c2cecd/313e37939e78188caf908eeffc41fe7c.webp)
省去了对变量进行 =@var or (@var=”)的判断。
抛弃 SQL 拼接,提高代码可读性。
尽量想办法使用临时表扫描替代全表扫描。
抛弃 in 和 not in 语句,使用 exists 和 not exists 替代。
和客户确认,模糊查询是否有必要,如没有必要,去掉 like 语句。
注意建立适当的,符合场景的索引。
踩死 “*” 号。
避免在 where 条件中对字段进行函数操作。
对实时性要求不高的报表,允许脏读(with(nolock))。
存储过程
