mysql嵌套查询语句

SELECT * FROM tb_login WHERE userid NOT IN (SELECT userid FROM tb_login LIMIT 5) LIMIT 4这样吧

select a.TerminalName, a.Capability,c.OrganIDfrom t_terminal a,t_vehicleorgan b,t_userorgan cwhere a.VehicleID=b.VehicleID and b.OrganID =c.OrganID and c.UserID = ?这样试试,最后的userid=?那自己输入一个值

这个好象直接用JOIN查询就可以了吧.select *from 一个评论的表 a,一个评论的表 b, 一个评论的表 cwhere a.id=b.parentID and b.id=c.parentID

一使用SELECT子句进行多表查询SELECT 字段名 FROM 表1,表2 … WHERE 表1字段 = 表2字段 AND 其它查询条件SELECT a.id,a.name,a.address,a.date,b.math,b.english,b.chinese FROM tb_demo065_tel AS b,tb_demo065 AS a WHERE a.

进行嵌套查询的时候子查询出来的的结果是作为一个派生表来进行上一级的查询的,所以子查询的结果必须要有一个别名例如:把mysql语句改成:select count(*) from (select * from ……) as total;问题就解决了,虽然只加了一个没有任何作用的别名total,但这个别名是必须的

sql语句里有嵌套查询,如:select sname from student where sno inselect sno from sc where cno='2';这样得查询可以实现一条指令对两个表操作可在php里我用这个命令来对mysql操作时显示sql语句错误!!不支持,mysql不支持嵌套查询,不

select max(id) from( select id,A,B from table1 where A>0 and B>0)t1加个表别名试试

select yr_student_info.name from yr_student_info where yr_student_info.school_id in (select yr_school_info.id from yr_school_info where yr_school_info.province='上海' and yr_school_info.city='上海')

select SKTNO,SUM(XSJE) XSJE FROM XSJL查询每个收款台的总销售金额.

select * from aaa where time1 in (select time2 from bbb)
