在 T-SQL 过程中建立上限/下限
我正在尝试在我的存储过程中建立上限/下限 下面,最后遇到了一些问题(我没有得到任何结果 其中,如果没有临时表内部连接,我会得到预期的结果)。 我在尝试加入临时表中的列时需要一些帮助#PageIndexForUsers 我的连接声明的其余部分,我搞砸了一些东西 这个声明:
<前><代码>内连接 #PageIndexForUsers ON ( dbo.aspnet_Users.UserId = #PageIndexForUsers.UserId AND #PageIndexForUsers.IndexId >= @PageLowerBound AND #PageIndexForUsers.IndexId <= @PageUpperBound )
此时我可以使用反馈 - 以及有关如何改进的任何建议 我的程序的逻辑(如果您看到其他需要改进的地方)也值得赞赏。
提前致谢...

I am trying to establish upper / lower bound in my stored procedure
below and am having some problems at the end (I am getting no results
where, without the temp table inner join i get the expected results).
I need some help where I am trying to join the columns in my temp table #PageIndexForUsers
to the rest of my join statement and I am mucking something up with
this statement:
INNER JOIN #PageIndexForUsers ON ( dbo.aspnet_Users.UserId = #PageIndexForUsers.UserId AND #PageIndexForUsers.IndexId >= @PageLowerBound AND #PageIndexForUsers.IndexId <= @PageUpperBound )
I could use feedback at this point - and, any advice on how to improve
my procedure's logic (if you see anything else that needs improvement) is also appreciated.
Thanks in advance...

#PageIndexForUsers
中没有足够的行,不是吗?如果 @PageSize = 50 并且您需要 @PageIndex 2,那么您将从
#PageIndexForUsers
中查找第 100 到 149 行。你有这么多行吗?行过滤器应应用于从
FROM dbo.wb_Profiles
开始的较大数据集You don't have enough rows in
#PageIndexForUsers
, no?If @PageSize = 50 and you want @PageIndex 2, then you are looking for rows 100 to 149 from
#PageIndexForUsers
. Do you have this many rows?The row filter should be applied over the larger dataset that starts
FROM dbo.wb_Profiles
