mysql sqlserver分页_SqlServer、MySql万能分页代码
sql數(shù)據(jù)庫中常用的分頁 我做了一個萬能的 用的上的小伙伴拿去耍吧
go? ----SqlServer萬能分頁代碼
create procedure [dbo].[sp_datapager]
@pagesize int,--每一頁的大小
@pageindex int,--頁碼數(shù)
@tablename varchar(Max),--表的名稱
@keycolumn varchar(20),---主鍵id
@columns varchar(200),--要查詢出列的名稱
@where varchar(200),---查詢條件
@orderby varchar(100),---排序方式
@recordcount int out--輸出參數(shù)，非0則返回要查詢表的總記錄數(shù)
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通用分頁加條件
delimiter //
drop procedure if exists `WebPager`;
create DEFINER=`root`@`%` procedure WebPager
(
in tableName varchar(4000),-- 表關(guān)系
in selectField varchar(4000),-- 要查詢的字段
in strwhere varchar(4000),-- 條件
in ordering varchar(1000),-- 排序字段
in sort int,-- 排序方式 0表示順序，1表示倒序
in pageIndex int,-- 當(dāng)前頁數(shù)
in pageSize int ,-- 每頁顯示的記錄數(shù)
out rows int -- 總行數(shù)
)
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 -- 判斷條件是否為空
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();-- 獲取總記錄數(shù)
end; //
-- call WebPager('card_manager','*','Del_Flag=0 and Balance>1000','Card_Code',1,1,2,@rows); select @rows;
