我有一个由其他人构建的应用程序需要编辑。有一部分代码我找不到正确的语法。。。有人能帮忙吗

POSTGRES中的select语句如下所示：

SELECT collection|| '/' ||color AS collection
FROM table
WHERE series = 'random number' <-- this is controlled by an array in the php

$tableName = $db->getOne('SELECT collection FROM item_series WHERE series = ?', array($series['marriage_1']));
}else{$tableName = $series['marriage_1'];}

我尝试过这个，但它不起作用：

$tableName = $db->getOne('SELECT collection, ".'/'.", color AS collection FROM item_series WHERE series = ?', array($series['marriage_1']));
}else{
$tableName = $series['marriage_1'];}

请帮忙，我已经找了几个小时的答案了

不是这样吗

$db->getOne('select collection || \'/\' || color as collection ...', ...);

还是这个

$db->getOne("select collection || '/' || color as collection ...", ...);

您的尝试：

'SELECT collection, ".'/'.", color AS collection FROM item_series WHERE series = ?'

将此SQL终止到数据库：

SELECT collection, "/", color AS collection FROM item_series ...

PostgreSQL不会因为您试图对字符串文本使用双引号而感到不安，它会认为您试图访问一个名为

的列。此外，您希望连接，并且希望使用

SQL运算符来实现连接。
