PHP:执行更新查询字符串时出现查询函数错误

我有一个疑问。这个查询与phpMyAdmin一起工作，但是当这个查询由PHP执行时，我有一个错误。原因可能是什么

我的PHP代码是：

var_dump($sql);
query($sql); 

调试时：

这是查询字符串：

 UPDATE searchcolumnsets SET name = "Project X",jsonfields = "[{\"name\":\"cm:contentPropertyName\",\"title\":\"Thumbnailed Content Property Name\",\"description\":\"\",\"datatype\":\"\"},{\"name\":\"cm:defaultHomeFolderPath\",\"title\":\"Percorso cartella homepage\",\"description\":\"\",\"datatype\":\"\"},{\"name\":\"trx:enabled\",\"title\":\"Abilitato\",\"description\":\"\",\"datatype\":\"\"},{\"name\":\"cm:identifier\",\"title\":\"Identificativo\",\"description\":\"\",\"datatype\":\"\"},{\"name\":\"cm:expiryDate\",\"title\":\"Data di scadenza\",\"description\":\"Data di scadenza\",\"datatype\":\"d:date\"},{\"name\":\"cm:hits\",\"title\":\"Conteggio\",\"description\":\"Conteggio\",\"datatype\":\"d:int\"}]" WHERE id = 50

这就是错误：

您的SQL语法有错误；检查与MySQL服务器版本对应的手册，以了解在第1行的“name”：“cm:contentPropertyName”，“title”：“Thumbnaild Content Property name”，“desc”附近使用的正确语法

您可以改用单qoute。 试试这个

UPDATE searchcolumnsets SET name = 'Project X',jsonfields = '[{\"name\":\"cm:contentPropertyName\",\"title\":\"Thumbnailed Content Property Name\",\"description\":\"\",\"datatype\":\"\"},{\"name\":\"cm:defaultHomeFolderPath\",\"title\":\"Percorso cartella homepage\",\"description\":\"\",\"datatype\":\"\"},{\"name\":\"trx:enabled\",\"title\":\"Abilitato\",\"description\":\"\",\"datatype\":\"\"},{\"name\":\"cm:identifier\",\"title\":\"Identificativo\",\"description\":\"\",\"datatype\":\"\"},{\"name\":\"cm:expiryDate\",\"title\":\"Data di scadenza\",\"description\":\"Data di scadenza\",\"datatype\":\"d:date\"},{\"name\":\"cm:hits\",\"title\":\"Conteggio\",\"description\":\"Conteggio\",\"datatype\":\"d:int\"}]' WHERE id = 50
