在AWS RDS中将sqlite3从Django迁移到mysql时始终报告语法错误
我正在AWS RDS中将django sqlite3迁移到mysql(我对mysql非常陌生)。我所做的是: (1) 首先,我通过在AWS RDS中将sqlite3从Django迁移到mysql时始终报告语法错误,mysql,django,amazon-web-services,sqlite,Mysql,Django,Amazon Web Services,Sqlite,我正在AWS RDS中将django sqlite3迁移到mysql(我对mysql非常陌生)。我所做的是: (1) 首先,我通过sudosqlite3db.sqlite3.dump>/home/ubuntu/temp.sql (2) 然后我尝试了sudomysql-h MYRDSHOSTNAME-u MYUSERNAME-p3306-pmydb
sudosqlite3db.sqlite3.dump>/home/ubuntu/temp.sql
(2) 然后我尝试了sudomysql-h MYRDSHOSTNAME-u MYUSERNAME-p3306-pmydb
(3) 输入密码后,我得到了这个
您的SQL语法有错误;检查与MySQL服务器版本对应的手册,以了解第1行“PRAGMA foreign_keys=OFF”附近使用的正确语法
我尝试删除temp.sql中的第一行,但随后发生了相同的错误,它仍然指向第1行
我还检查了RDS中的mydb,以确保它确实存在。它就在那里(当然是空的)。
RDS上的MySQL引擎版本为5.6.22,django电脑上的MySQL引擎版本为5.6.19
有没有什么我忽略了或做错了?非常感谢你们 SQLite3和MySQL的语法略有不同。看看这个问题:啊哈!谢谢我现在正在玩翻译脚本。sqlite中有一个独特的(xxx,yyy)。我应该在MySQL中删除这个吗?据说在MySQL中没有使用UNIQUE。
