没办法了来提问 SQL
[解决办法]

alter proc usp_GetAllLogsSelect_Pages 
AS
begin
declare @Category int,
        @Visible int,
@Uname varchar(50),
@PageSize int,
@PageIndex int,
@x int,
@y int
set @x=(@PageIndex-1)*@PageSize+1
set @y=(@PageIndex)*@PageSize

exec ('select* from(
      select ROW_NUMBER() over(order by ReleaseTime desc) as Rownum,
      LId,LogName,Abstract,CommentNo,ReadNo,UName,Category,ReleaseTime
      from Logs
      where Category='+@Category+' and Visible='+@Visible+' and Uname like '+@Uname+')
      as log
      where Rownum between '+@x+' and ' +@y) 
end

你要把参数传递好
[解决办法]
where Category='+@Category+' and Visible='+@Visible+' and Uname like '+@Uname+')

改成

where Category='+@Category+' and Visible='+@Visible+' and Uname like '''+@Uname+''')

就可以啦你试试吧

最简单的方法是把你的exec改成print，然后调试，通常都是单引号和双引号的问题和类型转换的问题而已

改成

where Category='+@Category+' and Visible='+@Visible+' and Uname like '''+@Uname+''')

哇塞，真的成功了，这是啥原理啊？！！！！

主要的问题在于@uname变量时varchar类型的，在动态拼接语句时，如果是要拼接字符串的值，你要生成如下的语句：
……and Uname like '字符串值'

但你上面的语句拼接的时候少了括住@uname值的引号:
' and Uname like '+ @Uname

那么为了加上引号，拼接的时候必须要写成这样，要把引号写两次：
' Uname like '''+ @Uname + ''''

[解决办法]
create proc usp_GetAllLogsSelect_Pages后面用括号把参数括起来就可以了啊

create proc usp_GetAllLogsSelect_Pages
(
@Category int,
@Visible int,
@Uname varchar(50),
@PageSize int,
@PageIndex int
)
AS
declare @x int,@y int
set @x=(@PageIndex-1)*@PageSize+1
set @y=(@PageIndex)*@PageSize

exec ('select* from(
      select ROW_NUMBER() over(order by ReleaseTime desc) as Rownum,
      LId,LogName,Abstract,CommentNo,ReadNo,UName,Category,ReleaseTime
      from Logs
      where Category='+@Category+' and Visible='+@Visible+' and Uname like '+@Uname+')
      as log
      where Rownum between '+@x+' and ' +@y)
