在Access中模拟sql server存储过程翻页

sql server中翻页存储过程:
Create PROC blog_GetPagedPosts
(
@PageIndex int,
@PageSize int,
@BlogID int=0,
@PostType int=-1,
@CategoryID int=-1,
@Hiding bit =0,
@Count int output

)
as
DECLARE @PageLowerBound int
DECLARE @PageUpperBound int
SET @PageLowerBound = @PageSize * @PageIndex - @PageSize
SET @PageUpperBound = @PageLowerBound + @PageSize + 1

Create Table #IDs
(
TempID int IDENTITY (1, 1) NOT NULL,
EntryID int not null
)
Insert into #IDs(EntryID) select DISTINCT [ID] from view_Content where CategoryID=@CategoryID and blogID=@BlogID order by [ID] desc
SELECT vc.*
FROM View_Content vc
INNER JOIN #IDS tmp ON (vc .[ID] = tmp.EntryID)
WHERE tmp.TempID > @PageLowerBound
AND tmp.TempID ORDER BY tmp.TempID
SELECT @Count=COUNT(*) FROM #IDS
SELECT @Count=COUNT(*) FROM #IDS
DROP TABLE #IDS
return @Count
GO

在access中由于不支持存储过程,不能建立临时表只能在程序中实现
Access中实现如下,这也是我在myblog Access版中使用的:
public List GetPagedPost(PagedPost p, out int TotalRecords)
{
List list = new List();

using (OleDbConnection conn = GetOleDbConnection())
{
StringBuilder sql = new StringBuilder();
sql.AppendFormat("select [ID] from blog_Content as p ");//构造查询条件
if (p.CategoryID > 0)
{
sql.AppendFormat(",blog_Categories AS c, blog_Links AS l WHERE c.CategoryID=l.CategoryID and (p.ID=l.PostID ) and c.CategoryID={1} and p.BlogID={0} ",p.BlogID, p.CategoryID);
}
else
{
sql.AppendFormat(" where p.blogID={0} ", p.BlogID);
}
if (p.PostType != PostType.Undeclared)
{
sql.AppendFormat(" and p.PostType={0} ", (int)p.PostType);
}
sql.Append(" order by p.[DateUpdated] desc");
// NetDiskContext.Current.Context.Response.Write(sql.ToString());
//NetDiskContext.Current.Context.Response.End();
OleDbCommand MyComm = new OleDbCommand(sql.ToString(), conn);
List IDs = new List(); //获取主题ID列表
conn.Open();
using (OleDbDataReader dr = MyComm.ExecuteReader())
{
while (dr.Read())
{
IDs.Add((int)dr[0]);

}
}

TotalRecords=IDs.Count;//返回记录总数
if (TotalRecords return list;
int pageLowerBound = p.PageSize * p.PageIndex - p.PageSize;//记录索引
int pageUpperBound = pageLowerBound + p.PageSize ;
StringBuilder sb = new StringBuilder();
if (TotalRecords >= pageLowerBound)
for (int i = pageLowerBound; i {
sb.AppendFormat("{0},", IDs[i]);//构造ID in() 条件,取其中一页
}
else return list; //如没有记录返回空表
if(sb.Length>1)
sb.Remove(sb.Length - 1, 1);//删除最后一个逗号
MyComm.CommandText = string.Format("SELECT b.* , c.Account as Account FROM blog_Content b, Blog_Config c where b.BlogID=c.BlogID and b.[ID] in ({0}) order by b.dateadded desc", sb.ToString());
using (OleDbDataReader dr = MyComm.ExecuteReader())
{
while (dr.Read())
{
list.Add(DataHelp.LoadDayBook(dr));
}
}
return list;
}
}
