symfony doctrine：generate-module命令时出现sql语法错误

Question

所以，我的问题是......

我正在尝试执行此命令：

  

php symfony doctrine：generate-module --env =“my_env”--non-verbose-templates backend city_theme CityTheme

暂停后，我收到此错误：

  

SQLSTATE [42000]：语法错误或访问冲突：1064 SQL语法中有错误;检查与MySQL服务器版本对应的手册，以便在第1行的“？LIMIT 1”附近使用正确的语法。查询失败：“ SELECT c.id AS c__id，c.city_theme_id AS c__city_theme_id，c.description AS c_ description，c.excursions AS c _excursions，c.image AS c_ image，c.keywords AS c _keywords,c.name AS c_ name，c .slug AS c _slug，c.title AS c__title FROM city_theme_data c WHERE（c.city_theme_id =？）LIMIT 1 “

此模型的schema.yml是：

CityTheme: 
  columns: 
    city_id: integer 
    lang: string(2) 
    guides: string 
  relations: 
    City: 
      class: City 
      local: city_id 
      foreign: id 
      foreignAlias: CityThemes 
      onDelete: CASCADE 

CityThemeData: 
  columns: 
    city_theme_id: integer 
    description: {type: string(255)} 
    excursions: string 
    image: {type: string(255)} 
    keywords: {type: string(255)} 
    name: {type: string(255)} 
    slug: {type: string(255)} 
    title: {type: string(255)} 
  relations: 
    CityTheme: 
      class: CityTheme 
      local: city_theme_id 
      foreign: id 
      foreignAlias: CityThemesData 
      onDelete: CASCADE 

有什么建议吗？

提前致谢。
