问题：

如何修复“由：org.apache.derby.iapi.error.StandardException：语法错误：遇到”

孙成化
2023-03-14

commandAcceptanceException：通过JDBC语句执行DDL“CREATE table user(user_id integer not null,active integer,email varchar(255),last_name varchar(255),name varchar(255),password varchar(255),password varchar(255),primary key(user_id))”时出错

原因：java.sql.SqlSyntaxErrorexception：语法错误：在第1行第14列遇到“user”。

在检查我的pojo类时，我无法识别出哪里出了问题。

我尝试将“spring.jpa.hibernate.ddl-auto=update”添加到application.properties文件中，但这似乎对我没有帮助

下面是我的类和Stacktrace,非常感谢任何帮助
