Question

这是我的表有2列和5条记录。如何在临时表的2.5行中显示这5条记录。表示从该表中获取2行，并在存储过程中插入1行的临时表，其中包含4列

第二张图片是临时表我想要数据。如果将来我想在3行中显示10条记录，那么临时表中将有3.1行

表名Party_Details

PID       PartyName     Address 
------------------------------------
1           Shadab      Bareilly
2           Akbar       Moradabad
3           Aqib        Bareilly
4           Majid       Moradabad
5           Shaan       Bareilly

上表有5行。

如何在SQL Server存储过程的临时表的2.5行中显示它？

@GeorgeJoseph

如果我将它们显示为1，则临时表中将有10列，如

PartyName1,Address1,PartyName2,Address2............. PartyName5,Address5

Answer 1

 create procedure SP_Party_Details 
 as
 begin
 declare @id int
 set @id=(select COUNT(*) from Party_Details)

 DECLARE @tempTable TABLE(
    PID int primary key identity(1,1),
    PartyName varchar(20),
    Address varchar(50),
    PartyName1 varchar(20),
    Address1 varchar(50));

 DECLARE @I INT=(select Min(PId) from Party_Details);
 START:               

 If @I%2!=0
      insert into @tempTable(PartyName,Address) select p.PartyName, p.Address from Party_Details p where p.PId=@I
    else    
      update t set t.PartyName1=(select PartyName from Party_Details where PId=@I),
    t.Address1=(select Address from Party_Details where PId=@I) from @tempTable t where t.PId=(select max(pid) from @tempTable)

 SET @I+=1;
 IF @I<=@id GOTO START; 


 SELECT * FROM @tempTable;
 end

 exec SP_Party_Details

Got Expected output

Answer 2

6列

create procedure [dbo].[SP_Party_Details_Three_Step]
as
begin
declare @id int
set @id=(select COUNT(*) from Party_Details)

DECLARE @tempTable TABLE(
    PID int primary key identity(1,1),
    PartyName varchar(20),
    Address varchar(50),
    PartyName1 varchar(20),
    Address1 varchar(50),
    PartyName2 varchar(20),
    Address2 varchar(50));

DECLARE @I INT=(select Min(PId) from Party_Details);
START:             

If((select Count(*) from @tempTable where PartyName2 is null)=0)
    insert into @tempTable(PartyName,Address) select p.PartyName, p.Address from Party_Details p where p.PId=@I

    else if((select Count(*) from @tempTable where PartyName1 is null)>0)
    update t set t.PartyName1=(select PartyName from Party_Details where PId=@I),
    t.Address1=(select Address from Party_Details where PId=@I) from @tempTable t where t.PId=(select max(pid) from @tempTable)     

    else
    update t set t.PartyName2=(select PartyName from Party_Details where PId=@I),
    t.Address2=(select Address from Party_Details where PId=@I) from @tempTable t where t.PId=(select max(pid) from @tempTable)

  PRINT @I;
  SET @I+=1;
IF @I<=@id GOTO START; 


SELECT * FROM @tempTable;
end

exec [SP_Party_Details_Three_Step]

将多行显示到临时表的列中
