怎麼實現
復制代碼 代碼如下:
select * from A where A.name like (select B.name from B where B.sex=1)
----------------------------------------------------------------------------------------------------------------------------
sqlserver寫法
復制代碼 代碼如下:
select distinct a.no,a.name from a,b where charindex(b.name,a.name)>0 and b.sex=1
oracle寫法
復制代碼 代碼如下:
select distinct a.no,a.name from a,b where instr(a.name,b.name)>0 and b.sex=1
----- instr() 定位子串 instr('Hello World', 'or') 返回8
