ProgrammingError: 1064 while executing inspectdb with django and mysql database
ProgrammingError: 1064 while executing inspectdb with django and mysql database
我在 settings.py 中配置了两个数据库：
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'postgres',
'USER': 'postgres',
'PASSWORD': 'password',
'HOST': '127.0.0.1',
'PORT': '5432',
},
'db2': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'database',
'USER': 'user',
'PASSWORD': 'password',
'HOST': 'ip address',
'PORT': 'port',
}
}
托管 db2 的服务器使用 mysql 4.1.2。我正在使用 Python 3.7.3 + django 2.2.5 + mysqlclient 1.4.4.
当我 运行 python manage.py inspectdb --database db2 我得到以下错误：
django.db.utils.ProgrammingError: (1064, "You have an error in your SQL >syntax; check the manual that corresponds to your MySQL server version for >the right syntax to use near 'TABLES' at line 1")
我打印了 'query'，它是：SHOW FULL TABLES
我已经尝试手动连接到数据库（MySQLdb.connect + 游标）并从 table 检索数据并且工作正常。
我的问题和(Error 1064 Django inspectdb)基本一样，但是那个人没有得到任何帮助。希望我会。
我想要完成的是默认使用来自 db2 的数据作为外键。例如，我在默认数据库中描述了一些项目，在 db2 中定义了一些人。我想将 db2 中的一个人与默认的项目相关联。为此，我认为使用 inspectdb 构建模型会有所帮助。
完整输出为：
# This is an auto-generated Django model module.
# You'll have to do the following manually to clean this up:
# * Rearrange models' order
# * Make sure each model has one field with primary_key=True
# * Make sure each ForeignKey has `on_delete` set to the desired behavior.
# * Remove `managed = False` lines if you wish to allow Django to create, modify, and delete the table
# Feel free to rename the models, but don't rename db_table values or field names.

如果我用SHOW TABLES替换SHOW FULL TABLES，我还需要更改函数的return。如果我可以用与当前 return 函数等效但没有 VIEW 部分的方式执行此操作，有什么想法吗？
