Sql Server行转列示例：

--创建部门表，写入数据 create table Table_Dep( depid varchar(10), dname varchar(50) ) insert into Table_Dep values('1','国内业务一部') insert into Table_Dep values('2','国内业务二部') insert into Table_Dep values('3','国内业务三部') insert into Table_Dep values('4','国际业务部')  --创建业绩表，写入数据 create table Table_Yeji( mon varchar(20), depid varchar(20), yj varchar(30) ) insert into Table_Yeji values('一月份','1','10') insert into Table_Yeji values('一月份','2','10') insert into Table_Yeji values('一月份','3','5') insert into Table_Yeji values('二月份','2','8') insert into Table_Yeji values('二月份','4','9') insert into Table_Yeji values('三月份','3','8')  --输出结果：部门、名称、一月份、二月份、三月份 select A.depid,A.dname,B.一月份,B.二月份,B.三月份 from Table_Dep A left join  (select depid, MAX(case mon when'一月份' then yj else null end)'一月份', MAX(case mon when'二月份' then yj else null end)'二月份', MAX(case mon when'三月份' then yj else null end)'三月份' from Table_Yeji group by depid) B on A.depid=B.depid  --pivot函数行转列 select A.depid,A.dname,B.一月份,B.二月份,B.三月份 from Table_Dep A left join  (select * from Table_Yeji pivot(max(yj) for mon in(一月份,二月份,三月份))tb) B on A.depid=B.depid
