存储过程实现分页

 1 -------------------------------------------------------以下代码为存储过程代码
 2 
 3 CREATE procedure   News_Class
 4 
 5 --资讯新闻百万级分页
 6 
 7 (
 8 
 9 @StrWhere     varchar(100),--条件
10 
11 @PageSize     int,         --页面大小
12 
13 @PageIndex     int        --页面索引
14 
15 )
16 
17 AS
18 
19 declare   @strSQL         varchar(2000)     -- 主语句
20 
21 declare   @strCountSQL   varchar(2000)     -- 总记录主语句
22 
23 declare   @strTmp         varchar(1000)     -- 临时变量
24 
25 Set @strTmp =" Select top " + str(@PageSize) + " Title,AddTime from Tb_News "   --此处注意，需几个字段读几个字段
26 
27 if @StrWhere<>''
28 
29    Begin
30 
31   Set @strSQL=@strTmp + " where ID < (select min(ID) from (select top " + str((@PageIndex-1)*@PageSize)+" ID from Tb_News Where "+@StrWhere+"   order by ID desc)   as tblTmp ) and "+@StrWhere+" order by ID desc"
32 
33    set @strCountSQL="select count(ID) as countx from Tb_News Where "+@StrWhere+" "
34 
35    End
36 
37 else
38

40 
41    Set @strSQL=@strTmp + " where ID < (select min(ID) from (select top " + str((@PageIndex-1)*@PageSize)+" ID from Tb_News order by ID desc)   as tblTmp ) order by ID desc"
42 
43    set @strCountSQL="select count(ID) as countx from Tb_News "
44 
45    End
46 
47 if @PageIndex = 1
48 
49    if @StrWhere<>''
50 
51        Begin
52 
53        Set @strSQL=@strTmp +" Where "+@StrWhere+" order by ID desc"
54 
55        End
56

64 
65 exec (@strSQL)
66 
67 exec (@strCountSQL)
