  • SqlServer、MySql万能分页代码

    sql数据库中常用的分页 我做了一个万能的 用的上的小伙伴拿去耍吧

    go  ----SqlServer万能分页代码
    create procedure [dbo].[sp_datapager]
    @pagesize int,--每一页的大小
    @pageindex int,--页码数
    @tablename varchar(Max),--表的名称
    @keycolumn varchar(20),---主键id
    @columns varchar(200),--要查询出列的名称
    @where varchar(200),---查询条件
    @orderby varchar(100),---排序方式
    @recordcount int out--输出参数,非0则返回要查询表的总记录数

    as
    declare @sql nvarchar(3000)
    declare @rcsql nvarchar(1000)
    set @rcsql='select @rc=count(*) from '+@tablename
    set @sql='select top '+convert(varchar(3),@pagesize)+' '+ @columns+' from '+
    @tablename +' where '+@keycolumn+' not in(select top '+
    convert(varchar(10),(@pageindex-1)*@pagesize)+' '+@keycolumn+
    ' from '+@tablename+')'
    if (@where!='')
    begin
    set @rcsql='select @rc=count(*) from '+@tablename+' where '+@where
    set @sql='select top '+convert(varchar(3),@pagesize)+ @columns+' from '+
    @tablename +' where '+@keycolumn+' not in(select top '+
    convert(varchar(10),(@pageindex-1)*@pagesize)+' '+@keycolumn+
    ' from '+@tablename+' where '+@where+') and '+@where
    end
    if (@orderby!='')
    begin
    if (@where!='')
    begin
    set @sql='select top '+convert(varchar(3),@pagesize)+ @columns+' from '+
    @tablename +' where '+@keycolumn+' not in(select top '+
    convert(varchar(10),(@pageindex-1)*@pagesize)+' '+@keycolumn+
    ' from '+@tablename+' where '+@where+' order by '+@orderby+') and '+
    @where+' order by ' +@orderby
    end
    else
    begin
    set @sql='select top '+convert(varchar(3),@pagesize)+ @columns+' from '+
    @tablename +' where '+@keycolumn+' not in(select top '+
    convert(varchar(10),(@pageindex-1)*@pagesize)+' '+@keycolumn+
    ' from '+@tablename+' order by '+@orderby+')'+' order by ' +@orderby
    end

    end
    declare @param nvarchar(100)
    set @param='@rc int output'
    exec sp_executesql @sql
    exec sp_executesql @rcsql,@param,@rc=@recordcount output

    MySql通用分页加条件

    delimiter //
    drop procedure if exists `WebPager`;
    create DEFINER=`root`@`%` procedure WebPager
    (
    in tableName varchar(4000),-- 表关系
    in selectField varchar(4000),-- 要查询的字段
    in strwhere varchar(4000),-- 条件
    in ordering varchar(1000),-- 排序字段
    in sort int,-- 排序方式 0表示顺序,1表示倒序
    in pageIndex int,-- 当前页数
    in pageSize int ,-- 每页显示的记录数
    out rows int -- 总行数
    )
    begin
    -- declare sqlstr varchar(4000);
    set @sqlstr=concat('select SQL_CALC_FOUND_ROWS ',selectField,' from ',tableName,' where 1=1 ');
    if strwhere is not null then -- 判断条件是否为空
    set @sqlstr=concat(@sqlstr,' and ',strwhere);
    end if;
    if ordering is not null then
    if sort=0 then
    set @sqlstr=concat(@sqlstr,' order by ',ordering);
    end if;
    if sort=1 then
    set @sqlstr=concat(@sqlstr,' order by ',ordering,' desc');
    end if;
    end if;
    set @sqlstr=concat(@sqlstr,' limit ',(pageIndex-1)*pageSize,',',pageSize);

    -- select sqlstr;
    PREPARE distSQL FROM @sqlstr;
    EXECUTE distSQL;
    DEALLOCATE PREPARE distSQL;

    set rows=FOUND_ROWS();-- 获取总记录数
    end; //

    -- call WebPager('card_manager','*','Del_Flag=0 and Balance>1000','Card_Code',1,1,2,@rows); select @rows;
