|
||
* 版本号: v1.0
|
||
* 创建日期: 2016-03-21
|
||
* 最后修改日期: 2018-04-27
|
||
* 功能: 对PDO类的简单封装，暂仅支持MSSQL、MYSQL、ORACLE
|
||
* by: bahamut
|
||
**************************************************************************
|
||
* 2016-03-21：
|
||
* 创建文件。
|
||
* 2016-03-22：
|
||
* 增加ORACLE支持。
|
||
* 2016-03-25：
|
||
* 增加EXCEL文件导出。
|
||
* 2016-03-29：
|
||
* Request方法新增回调函数的支持，ExportToFile方法支持指定新的查询语句和参数。
|
||
* 2016-04-14:
|
||
* 增加Succeeded方法来判断pdo类的errorcode值是否成功。
|
||
* 增加对MYSQL的支持（MYSQLHelper类），在Connect方法中，创建PDO对象后，立即执行"use database;"语句（如果不执行，mysql会报'no selected database'的错误。）。
|
||
* 2016-04-20:
|
||
* 修改Connect方法，参数提供默认参数，并可支持数组方式传递。
|
||
* 2016-05-01:
|
||
* 新增LastInsertId方法，用来获取最后一次新增数据时产生的自动编号。
|
||
* 2016-05-10:
|
||
* 新增错误返回值(ERRORCODE_CUSTOMFIRST、ERRORCODE_CUSTOMLAST)，用于提供后期扩展。
|
||
* 2016-05-11:
|
||
* 新增ReplaceValue函数用来处理特殊字符。
|
||
* 2016-05-12:
|
||
* 修改SetErrors方法，errorinfo总是获取最后一个元素（如果是对象或者数组）。
|
||
* 2016-05-20:
|
||
* 增加FetchStyle成员, 用来设置提取记录时的提取方式（默认PDO::FETCH_OBJ）。
|
||
* 2016-07-08:
|
||
* MYSQLHelper增加可用参数charset，用来指定数据库的编码，默认为utf8
|
||
* 2016-08-05:
|
||
* 新增GetParameterList方法，用来处理传入类型为array与object的参数。
|
||
* 2017-01-05:
|
||
* 新增BindParameter和LoadStream属性, 用来支持大数据类型。
|
||
* BindParameter为true表示强制按传入的参数大小绑定参数到pdo对象中，
|
||
* LoadStream为true表示将判断查询语句中的返回值类型，如果为resorce则会用stream_get_contents去读取这个资源的实际值
|
||
* 2017-04-01:
|
||
* 新增接口IDatabaseHelper用于描述DatabaseHelper类的方法。
|
||
* 2017-04-06:
|
||
* 新增SQLCommand类来实现sql语句的封装。
|
||
* 2017-04-10:
|
||
* 新增CommandParameters类和CommandParameter类，用于扩展DatabaseHelper的Request和Execute方法。
|
||
* 扩展DatabaseHelper的Request和Execute方法，让传入的参数支持CommandParameter类型。
|
||
* 作废BindParameter和LoadStream属性, 总是支持大数据类型.
|
||
* 2017-07-03:
|
||
* ISQLCommand新增CallStoredProcedure方法用来调用存储过程或函数.
|
||
* 2017-07-16:
|
||
* ISQLCommand新增Union方法用来连接其他结果集（union all语句）.
|
||
* 2017-07-24:
|
||
* IDatabaseHelper接口增加方法NextRowset用来移动当前记录集指针（用于多记录集时切换记录集操作），
|
||
* IDatabaseHelper接口增加方法Records用来获取当前已打开的记录集，
|
||
* DatabaseHelper类增加属性OnConnected(连接), OnDisconnected(断开连接), OnBeforeOpen(打开记录前), OnAfterOpen(打开记录后), OnBeforeExecute(执行命令前), OnAfterExecute(执行命令后), OnError(错误)用来捕捉事件。
|
||
* 2017-12-14:
|
||
* 解決了在設置條件時（where, join on, having等）當設置值為null時，出現的bug.
|
||
* 2018-01-21:
|
||
* 增加ExportToBrowser方法（无需服务器端缓存临时文件。）用于导出excel文件。
|
||
* ExportToBrowser方法导出并没有做分页处理，如果后期出现out of memory的情况则需要做分页导出。
|
||
* 2018-04-27:
|
||
* IDatabaseHelper改名为IPDOHelper, DatabaseHelper改名为PDOHelper.
|
||
* 2018-05-28:
|
||
* PDOHelper增加CacheRecord属性用来控制在执行有回调函数的查询语句时，是否把查询到的记录缓存到本地。
