Question

我想循环PRINT 3次FOR每次从这个3 SELECT

打印一个单词

PRINT I'm mark  

PRINT HI
PRINT hello
PRINT how are you

我试试这个

DECLARE @i INT
SET @i = 0

PRINT 'Im mark' 
WHILE @i < 1
BEGIN
PRINT 'hi' 
SET @i = @i + 1
END 
PRINT '-------------------'
SET @i = 0
PRINT 'Im mark' 
WHILE @i < 1
BEGIN
PRINT 'hello' 
SET @i = @i + 1
END 
PRINT '-------------------'
SET @i = 0
PRINT 'Im mark' 
WHILE @i < 1
BEGIN
PRINT 'how are you' 
SET @i = @i + 1
END

但它循环所有块3次我希望结果是这样的我想要一个循环它只是一个简单的例子我的工作很大

-----loop I------
I'm mark  
Hi

-----loop II------
I'm mark  
hello

-----loop III------
I'm mark 
how are you

Answer 1

create table #test(id int,col varchar(50));
insert into #test values(1,'HI');
insert into #test values(2,'hello');
insert into #test values(3,'how are you');


declare @msg varchar(50);
declare @i int;
declare @msgTemp varchar(50);

set @msg='I m Mark' + CHAR(13); -- Char(13) is the New Line character in TSQL
set @i=1;

while(@i<4)
      begin
        print @msg

        select @msgTemp=col
        from #test where id=@i

        print @msgTemp + CHAR(13)

        set @i=@i+1;
      end

Drop table #test

循环打印3次FOR每次打印一个字从这3打印
