ThinkPHP2.0读取MSSQL提示Incorrect syntax near the keyword '_PHP
ThinkPHP
问题代码如下:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
|
出现的情况是使用 query 可以正确读取到数据,而使用M方法,则无法读取,会报出 Incorrect syntax near the keyword 'AS'. 错误
原因是DbMssql.class.php驱动的查询语句有问题。
由于TP2.0 的 MSSQL 驱动是对SQL 2005有效,但对2000版本则无效,原因是2000版本里没有 ROW_NUMBER 功能,2005才有这个功能作用好像是对数据分页提供便利和效能。
希望官方能够给TP2.0加一个2000的驱动吧,目前采用的临时处理方法是修改ThinkPHP\Lib\Think\Db\Driver\DbMssql.class.php ,将行 25 的 protected $selectSql 在前面加 '//'
并且第326行 的
1 2 3 4 5 6 7 8 9 |
|
改为:
1 2 3 |
|
这样更改后,基本可以满足一般的SQL需求,但不能使用LIMIT,因为 MSSQL 2000 的LIMIT方法是以 top N
这样实现的;
如果觉得麻烦,那么就结合 Adodb 类库吧,这个对MSSQL支持相对好很多。要结合 Adodb 类库我的方法如下:
首先下载 Adodb 类库并解压到 ThinkPHP 的 Vendor 目录中,并把 adodb.inc.php 改名为 adodb.php
然后在项目的 Lib 里建立一个 CommonAction.class.php 内容为
1 2 3 4 5 6 7 8 9 10 11 12 |
|
在项目的其他文件中都要引用到这个 CommonAction.class.php 文才能使用 ADODB,例如:
1 2 3 4 5 6 7 8 9 10 |
|
这样既能使用 Thinkphp 的模块进行简单的数据查询也能使用 Adodb 进行分页数据的查询,实在是没办法中的办法了,这个是个笨办法哦,还是希望 ThinkPHP 能够出一个 MSSQL 2000 版本能用的完美驱动。
