坚持数据库Symfony2的MySQL错误

Question

问题：

将实体持久保存到带有理论的数据库中时，出现以下MySQL错误，我的实体名称都不是保留字。 我尝试了许多事情，包括重建数据库和表以及运行doctrine：schema：update，但无济于事。 任何帮助将不胜感激。

错误：

string（601）“执行'INSERT INTO版本（序列，标题，艺术家，长度，体裁，描述，曲目，下载，缩略图，插图）时发生异常。值（？，？，？，？，？，？，？，？ ，？，？，？）'与参数[“ FREELOV”，“ afds”，“ asdf”，“ 2:23”，“ asdf”，“ asdf”，“ fdsaf => 2:23”，“ FREELOV.zip “，” FREELOV.jpg“，” FREELOVThumb.jpg“]：SQLSTATE [42000]：语法错误或访问冲突：1064您的SQL语法有错误；请查看与您的MySQL服务器版本相对应的手册以获取正确的语法在第1行的'release（序列号，标题，艺术家，长度，体裁，描述，曲目，下载，th）附近使用”

RELEASE是MySQL中的保留字 。

如果您确实希望将表命名为release ，则必须在实体中设置表名称并对其进行qoute，如下所示：

<?php

/**
  * @ORM\Enity
  * @ORM\Table(name="`release`")
  */
class Release;

…

但是，如果您仍然可以选择其他名称，建议您这样做。 这样可以避免以后出现很多麻烦。
