--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
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))。
