HomeBackend DevelopmentPHP Tutorialphp mssql扩展SQL查询中文字段名解决方法_PHP

一、问题:

数据库是MS SQLServer2000,要把SQLServer2000里的一张表的数据导入MySQL5,其中SQLServer2000表的字段以简体中文命名(强烈建议不要以中文做为字段名)。其实操作就是对SQLServer查询记录,插入到MySQL里。选择的脚本语言是PHP,PHP打开MSSQL和MySQL扩展,对这两个数据库操作都是很容易的问题。
问题就出现在SQLServer中表的字段名是中文,写好的查询语句在SQLServe里测试是通过有记录返回,用PHP的MSSQL扩展查询就是报错。
上网查了资料,网上相关的信息不太多,很多网友都认为是PHP的MSSQL扩展不支持SQL语句中有中文。查了一下资料,PHP的MSSQL是支持SQL中有中文的语句。出现报错问题大多是因为编码的问题,编码数据库和编码与查询语句编码不统一,查询语句到SQLServer里中文部分就成了乱码,造成查询失败。

二、解决方法:

知道了原因,接下来分析解决,确认是编码不统一的问题。解决分以下几步:
1、确认SQLServer 数据库的编码,我的数据编码是GBK。
2、确认当前PHP脚本文件的编码,我的编码是UTF-8。
3、转换SQL查询语句的的编码。
补充:有的网友提到要把PHP的脚本文件编码转成和数据库编码一致,其实这一步大可不必,只要确认你的SQL语句和数据库的编码一致就可以,这里建议不必转换的原因是如果你的PHP脚本文件里包含其它PHP脚本,那也得对所有include或require的脚本文件编码转换,不然PHP脚本编码不统一很容易出错,若互相关联的文件很多,这也是一件很麻烦的问题而且把事情复杂化了。

三、方案:

写一个转换函数,在把SQL操作前把SQL语句编码转换。下面贴出我的范例代码:
复制代码 代码如下:
//编码转换函数
function utf8togb($s) {
return iconv('utf-8', 'gbk//IGNORE', $s); // IGNORE 参数是遇到不成转换的字符时忽略
}
//建议把所有中文字段用英文别名替换,方便下面操作还有编码转换等问题
$sql="SELECT [id], [栏目] as typeid, [正题] as title, [作者] as author, convert(text, [正文]) as body FROM [文章表];";
$sql = utf8togb($sql);

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
