sql server中返回 result table 函数的俩中写法

1，直接返回表结构数据

USE [CmxSystem]
GO
/****** Object: UserDefinedFunction [dbo].[Fun_CarsTransferList] Script Date: 2018/10/31 星期三 19:21:50 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER function [dbo].[Fun_CarsTransferList](@EntId int ,@UserNo varchar(30),@PageNo int)
returns table
as
return
(
   with CarsTransferInfo as(
   select c.TransferNo,b.ChineseName,c.FromUser,c.ToUser,c.CrtDate,c.ToEntId,
   (case c.Status when '0' then '未审批'when '1' then '审批通过'when '2' then '审批拒绝' end) Status
   from CarsTransfer c inner join EnterpriseUsersBaseInfo a
   on c.EntId=a.EntId
   inner join EnterpriseBaseInfo b
   on a.EntId=b.ID
   where c.EntId=@EntId and a.UserNo=@UserNo
   )
   , BaseInfo as(
   select a.ChineseName as name ,a.ID from EnterpriseBaseInfo a where ID in(
   select c.ToEntId from CarsTransfer c
   where c.EntId=31 )
   )

   SELECT TOP 20 *   FROM
       (
           SELECT
               ROW_NUMBER () OVER (ORDER BY id ASC) RowNumber ,c.TransferNo,c.ChineseName,c.FromUser,c.ToUser,c.CrtDate,c.ToEntId,
           c. Status,b.name
           from CarsTransferInfo c inner join BaseInfo b
           on c.ToEntId= b.ID
       ) A
   WHERE
A.RowNumber > (@PageNo - 1) * 20

)

2，返回表函数中需要使用变量做一些判断的方法在返回表数据

USE [CmxSystem]
GO
/****** Object: UserDefinedFunction [dbo].[Fun_AccountEntry] Script Date: 2018/10/31 星期三 19:23:45 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER FUNCTION [dbo].[Fun_AccountEntry]( @RdNo varchar(30),@EntId int)
RETURNS @Table TABLE(
RdNo varchar(20),
   EntId int ,
   Amount int,
   CrtDate datetime,
   Remark varchar(50),
   PayDocNo varchar(30),
   AccoutType varchar(30),
   CarsVin varchar(20),
   WhCode varchar(20),
   ArCode varchar(20)
)
AS
BEGIN
DECLARE @str char
select @str = LEFT(@RdNo,1)
   if (@str)='R'

   INSERT @Table select top 1 a.RdNo,a.EntId,a.Amount,a.CrtDate,a.Remark,a.PayDocNo,
   (CASE b.AccoutType
WHEN '1' THEN '充值'
               WHEN '2' THEN '费用'
               WHEN '3' THEN '预约'
               WHEN '4' THEN '退款'
END) as AccoutType
   ,b.CarsVin,'',''
       from EnterpriseRechargeDetm a inner join AccountEntry b on a.RdNo = b.BillNo
       where a.EntId=@EntId and a.RdNo=@RdNo

if (@str)='O'
INSERT @Table select a.BillNo,a.EntId,a.Amount,a.CrtDate,'','',b.WhCode,b.ArCode,

       (CASE a.AccoutType
WHEN '1' THEN '充值'
               WHEN '2' THEN '费用'
               WHEN '3' THEN '预约'
               WHEN '4' THEN '退款'
END) as AccoutType,
       a.CarsVin
       from AccountEntry a inner join OrderDetm b
       on a.BillNo=b.OrderNo
       where a.EntId=@EntId and a.BillNo=@RdNo

if (@str)='I'
INSERT @Table select a.BillNo,a.EntId,a.Amount,a.CrtDate,'','',b.WhCode,b.ArCode,
       (CASE a.AccoutType
WHEN '1' THEN '充值'
               WHEN '2' THEN '费用'
               WHEN '3' THEN '预约'
               WHEN '4' THEN '退款'
END) as AccoutType
           ,a.CarsVin
       from AccountEntry a inner join OrderDetm b
       on a.BillNo=b.OrderNo
       where a.EntId=@EntId and a.BillNo=@RdNo
RETURN
END
总结：应为函数中不能创建临时表所以使用该方法

RETURNS @Table TABLE(
RdNo varchar(20),
   EntId int ,
   Amount int,
   CrtDate datetime,
   Remark varchar(50),
   PayDocNo varchar(30),
   AccoutType varchar(30),
   CarsVin varchar(20),
   WhCode varchar(20),
   ArCode varchar(20)
) 相当于就是创建了临时表

在使用 insert @Table select * from table 的方法吧数据查出来赋值给新建的表中在返回
