JPA 为带有列定义的 MySql8 生成不正确的 SQL 查询

Question

I am using Springboot JPAs to generate a MySql8 table. It works fine unless I try to use the columndefinition in the Column annotation.

 @Column(columnDefinition = "boolean default false")
    private Boolean example;

I tried replacing boolean with TINYINT but MySql8 should support boolean as far as I am aware.

I get an error during the table generation:

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 ' boolean default false at line 5

To me it looks like the generated SQL Syntax has additional quotation marks but I am unsure how to fix the issue.

 create table `exampleTable` (
       `id` bigint not null auto_increment,
        `example` `boolean default false`,
        primary key (`id`)
    )

EDIT: I found my Issue in this question: Spring JPA globally_quoted_identifiers incorrectly quoting column type TEXT

Answer 1

if you want to set the default value of the example to be false then you can write it like this and remove columnDefintion from there

private Boolean example=false;

Answer 2

Disable quotes by adding spring.jpa.properties.hibernate.globally_quoted_identifiers=false to application.properties file

But after disabling, you will not be able to use column and table names that match mysql keywords (eg desc ). Workaround by adding an underscore:

@Column(name = "desc_")
String desc;
