完整的ASP.NET存储过程分页，排序，鼠标移至变色

首先建立一个存储过程如下（MySQL数据库）：
CREATE DEFINER=`root`@`localhost` PROCEDURE `pagination`(
       in tbName varchar(100),   /*表名*/
          fldName varchar(100),  /*排序关键字*/
          pageSize int,          /*每页显示行数*/
          pageIndex int,         /*当前显示第几页*/
          orderType int,         /*排序规则 0升序，1降序*/
          strWhere varchar(2000),/*查询条件 例如where 1=1*/
       out allPages int          /*传出参数 返回总行数*/
)
begin

declare beginRow int;
     declare sqlStr varchar(1000);
     declare limitTemp varchar(1000);
     declare orderTemp varchar(1000);
     declare allPageNum int;
    
     set allPageNum = 0;
     set beginRow = (pageIndex-1)*pageSize;
     set sqlStr = CONCAT('SELECT * from ',tbName);
     set limitTemp = CONCAT(' limit ',beginRow,',',pageSize);
     set orderTemp = CONCAT(' order by ',fldName);
     if orderType = 0 then
         set orderTemp = CONCAT(orderTemp,' ASC ');
     else
         set orderTemp = CONCAT(orderTemp,' DESC ');
     end if;
    
     set @sqlSelect = CONCAT(sqlStr,' ',strWhere,orderTemp,limitTemp);
    
     set @sqlCountRow = CONCAT('select count(*) into @countRow from ',tbName);
    
     prepare sqlstmt from @sqlSelect;
     execute sqlstmt;
     deallocate prepare sqlstmt;
    
     prepare sqlstmt from @sqlCountRow;
     EXECUTE sqlstmt;
     set allPages = @countRow;
     deallocate prepare sqlstmt;

end;
