SQL传递参数问题

declare @SqlWhereProject NVARCHAR(500)
set @SqlWhereProject='and ( FProjectNumber like ''%02.C13001%'')'
select * from t_Item_3001 where 1=1 &@SqlWhereProject
在执行以上语句时,为什么老是提示"在将 nvarchar 值 'and ( FProjectNumber like '%02.C13001%')' 转换成数据类型 int 时失败";谢谢!

declare @SqlWhereProject NVARCHAR(500),@sql nvarchar(4000) set @SqlWhereProject='and ( FProjectNumber like ''%02.C13001%'')'set @sql='select * from t_Item_3001 where 1=1 '+ @SqlWhereProject print @sql exec (@sql)
