end 
end 

------返回查询结果----- 
exec sp_executesql @strTmp 
--print @strTmp 
SET NOCOUNT OFF 
GO 

怎么在数据库中测试呢？

declare @pageCount int 
declare @Counts int 
exec [dbo].[proc_ListPageInt] "sysobjects", "* ", 20,1,@pageCount output,@Counts output,"id", 0,"","id",0
print @pageCount --这个可有可无 
print @Counts --这个可有可无 

执行效果如下：
