Question

declare @sql as varchar(max),@ID int=1,@maxID int 

WHILE 2155>=1       

BEGIN        

 SELECT  @sql= ColumnValue  from table where ID=@ID        

 declare  @table1 table(columnvalue2 nvarchar(max),id int IDENTITY(1,1))         

insert into @table1(columnvalue2)        

 exec (@sql )        

 update table set ColumnValue=isnull(b.columnvalue2,'') FROM table a jOIN 
@table1 b ON a.Id=b.id        

 SET @ID=@id+1        

 END         

SELECT distinct CID,Name,sorder,Locations,columnValue FROM table where isActive = 1 order by Locations,CID,Name

当我执行上述条件时它显示超时。可以为查询超时的任何一个帮助吗？

Answer 1

首先，SET @maxID = <some value>

然后，将WHILE 2155>=1更改为WHILE @ID<=@maxID，否则您的循环将永远不会结束......

while循环在sql中显示超时错误
