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;
