基于基于Sql Server通用分页存储过程的解决方法通用分页存储过程的解决方法
sql server2000分页方式很多，效率吗 当到达10万级以上就有些吃力了，这里暂时不例出来了
sql server2005以上就有了row_number 也是一大进步，详情如下参考
代码如下:
Sql Server2005通用分页存储过程
CREATE PROCEDURE [dbo].[Common_GetPagedList]
(
@TableName nvarchar(100), –表名
@ColumnNames nvarchar(1000) = ‘*’, –字段名集合(全部字段为*，其它逗号分隔)
@OrderClause nvarchar(1000), –排序从句(不包含order by)
@WhereClause nvarchar(1000) =N’ 1=1 ‘, –条件从句(不包含where)
@PageSize int = 0, –每页记录数(0为所有)
@PageIndex int = 1, –页索引(从1开始)
@TotalRecord int output –返回总记录数
)
AS
BEGIN
if (@ColumnNames is null or @ColumnNames=”) set @ColumnNames=’ * ‘
if (@WhereClause is null or @WhereClause=”) set @WhereClause=’ 1=1 ‘
if (@OrderClause is null or @OrderClause=”) set @OrderClause=’ Id desc ‘
–处理开始点和结束点
Declare @StartRecord int;
Declare @EndRecord int;
Declare @TotalCountSql nvarchar(1200);
Declare @SqlString nvarchar(4000);
–统计记录
if(@TotalRecord is null OR @TotalRecord>=0)
begin
SET @TotalCountSql= N’select @TotalRecord = count(*) from ‘ + @TableName +’ where ‘+@WhereClause;
–select @TotalCountSql
EXEC sp_executesql @totalCountSql,N’@TotalRecord int out’,@TotalRecord output;–返回总记录数
end
if @PageSize>0
begin
if @PageIndex<1 set @PageIndex=1
set @StartRecord = (@PageIndex-1)*@PageSize + 1
set @EndRecord = @StartRecord + @PageSize – 1
set @SqlString = N’select row_number() over (order by ‘+ @OrderClause +’) as rowId,’+@ColumnNames+’ from ‘+
@TableName+’ where ‘+@WhereClause;
set @SqlString =’select * from (‘ + @SqlString + ‘) as t where rowId between ‘ + ltrim(str(@StartRecord)) + ‘ and ‘ +
ltrim(str(@EndRecord));
end
else
begin
set @SqlString=’select ‘+@ColumnNames+’ from ‘+ @TableName+’ where ‘+@WhereClause +’ order by ‘+@OrderClause
end
–select @SqlString
Exec(@SqlString)
END
