ALTER proc [dbo].[GetAllForByFiled]
(
@table nvarchar(30),
@filed nvarchar(30),
@condition nvarchar(30)
)
as

declare @tableName varchar(30),@sql varchar(1000)
set @tableName =@table
set @sql='select * from '+@tableName+ ' where ' + @filed + ' = ' + @condition
exec(@sql)
return
我想问下我这个存储过程那里有错????
我将@table 附值老说他附近有语法错误.
新手不怎么回!
谢谢

@condition nvarchar(30)
)
as

declare @tableName nvarchar(30),@sql varchar(1000)
set @tableName =@table
set @sql='select * from '+@tableName+' where '+@filed+'=' +@condition
exec(@sql)
go

exec [dbo].[GetAllForByFiled] N'Orders',N'EmployeeID',5

drop proc [dbo].[GetAllForByFiled]

exec [dbo].[GetAllForByFiled] N'Orders',N'EmployeeID',5
想这样的话那不是参数不能外部传入哦

我只是用来测试而已..你想传入..你就传入咯.

condition是什么类型？如果是char则需要加上引号：

......+ '''' + CONDITION + ''''

nvarchar类型赋值给varchar时，应该能自动转换的吧？

谢谢!的确这样很难确定字段类型!
