问题是这样的:
1,创建一个存储过程
CREATE PROCEDURE Location
(
@Topcount int,
@Location char(50)
)
as
declare @strCounter varchar(10)
set @strCounter=convert(varchar(10),@Topcount)
exec('select top [email protected]+' * from tt where [_FontOrImage]=1 and [Location][email protected]+' Order By _Start_Time Desc')
GO
2,tt库表里的Location字段为char(50)
结果在查询分析器里查询时出现以下问题:
exec Location 1,'1k'
服务器: 消息 170，级别 15，状态 1，行 1
第 1 行: 'k' 附近有语法错误。
但是,当执行exec Location 1,'1'时可以查询出数据.
而'1k'和'1'字符串在Location字段都存在,为什么出现这样的问题啊?求求各位了!
------解决方案--------------------
- SQL code
--存储过程名不要和变量一样CREATE PROCEDURE [dbo].[sproLocation] ( @Topcount int, @Location char(50) ) as declare @strCounter varchar(10) set @strCounter=convert(varchar(10),@Topcount) exec('select top '+'([email protected]+')'+' * from tt where [_FontOrImage]=1 and [Location][email protected]+'Order By _Start_Time Desc') GO
------解决方案--------------------
- SQL code
--字符串前后要加引号，exec('select top [email protected]+' * from tt where [_FontOrImage]=1 and [Location][email protected]+' Order By _Start_Time Desc') --->exec('select top [email protected]+' * from tt where [_FontOrImage]=1 and [Location][email protected]+''' Order By _Start_Time Desc')
