Why Hibernate cant create DB? SQLSyntaxErrorException and CommandAcceptanceException

Question

I have three DBs, of which hibernate can only create 2/3. Can someone explain why hibernate can not create a third table "goods"

1: org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL "create table goods (ID integer not null, brand varchar(255), desc varchar(255), model varchar(255), price float(53) not null, type varchar(255), primary key (ID)) engine=InnoDB" via JDBC Statement ---> at Models.Main.main(Main.java:18) <--- 2: Caused by: java.sql.SQLSyntaxErrorException: 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 'desc varchar(255), model varchar(255), price float(53) not null, type varchar(25' at line 1

Answer 1

I went through your code. The only fishy part is

private String desc; 

"DESC" is reserved keyword in databases. If you look closely at the syntax(query) issued in your database, it will show you

CREATE TABLE goods (ID INTEGER NOT NULL,brand VARCHAR (255),DESC VARCHAR(255), model VARCHAR (255), price FLOAT (53) NOT NULL,TYPE VARCHAR(255), PRIMARY KEY (ID)) ENGINE = INNODB 

You can see the "DESC" turns blue and shows that it is reserved keyword for "descending". Try changing it to something else like "descs" or you can define column and change it to something else like`

@Column(name="descs")
private String desc;

It will work.`
