mysql分页存储过程一步一步实现

1. 

CREATE DEFINER=`root`@`localhost` PROCEDURE `P_HoverTreePages`(
    IN `TableName` VARCHAR(200),
    IN `FieldList` VARCHAR(2000)
,
    IN `PrimaryKey` VARCHAR(100),
    IN `Where` VARCHAR(2000),
    IN `Order` VARCHAR(1000),
    IN `SortType` INT,
    IN `RecorderCount` INT,
    IN `PageSize` INT,
    IN `PageIndex` INT,
    OUT `TotalCount` INT,
    OUT `TotalPageCount` INT




)
LANGUAGE SQL
NOT DETERMINISTIC
CONTAINS SQL
SQL SECURITY DEFINER
COMMENT ‘fenye‘
BEGIN

set @sqlStr = CONCAT(‘select * from ‘,TableName,‘ order by ‘,PrimaryKey,‘ desc limit ?,?‘);
     prepare sqlStr from @sqlStr ;
     
     set @hstart=PageSize*(PageIndex-1);
     set @hsize=PageSize;
     execute sqlStr using @hstart,@hsize;

END

调用：

CALL `P_HoverTreePages`(‘t_hovertreenote‘, ‘h‘, ‘hid‘, ‘h‘, ‘h‘, ‘1‘, ‘1‘, ‘3‘, ‘1‘, @hh, @yy)
