SQL基础:Sql Server中实现行数据转为列显示
场景:行数据的某列值想作为字段列显示
1、效果如下
2、解决方案
使用pivot进行行转列,以及结合分组
3、代码如下
select DeptName,InputCode
from FWD_Department
group by DeptName,InputCode
) as a
pivot(
max(InputCode) for DeptName in([随访中心],[全院],[家庭化产房],[妇科二],妇科一)
) piv
创建表:
GO
/****** Object: Table [dbo].[FWD_Department] Script Date: 2022/3/11 14:50:39 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[FWD_Department](
[id] [int] IDENTITY(1,1) NOT NULL,
[DeptName] [varchar](50) NOT NULL,
[InputCode] [nchar](10) NULL,
CONSTRAINT [PK_one] PRIMARY KEY CLUSTERED
(
[DeptName] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
SET ANSI_PADDING OFF
GO
表记录添加:
values(‘随访中心’,’SFZX’)
insert into one(DeptName,InputCode)
values(‘全院’,’QY’)
insert into one(DeptName,InputCode)
values(‘家庭化产房’,’JTHCF’)
insert into one(DeptName,InputCode)
values(‘妇科二’,’FKE’)
insert into one(DeptName,InputCode)
values(‘妇科一’,’FKY’)
