Im trying to make a REST api using springboot. Normally I would use PHPMyAdmin for the database but trying H2 out for the first time.
Havnt seen these issues come up in my old projects because I make the SQL database outside the project using PHPMyAdmin.
Any help would be extremely grateful.
This is the Maven Output Maven output

This is my schema.sql
DROP TABLE IF EXISTS accounts;
CREATE TABLE accounts (
accountnumber int(9) NOT NULL,
pin int(4) NOT NULL,
balance int(11) NOT NULL,
overdraft int(11) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
DROP TABLE IF EXISTS atm;
CREATE TABLE atm (
note_value String NOT NULL,
note_amount int(11) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
This is my Account object class
@Entity
public class Account {
@Id
private int accountNumber;
private int pin;
private double balance;
private double overdraft;

public Account(int accountNumber, int pin, double balance, double overdraft) {

[*] mark in exceptions from H2 indicates a position of parser error:
… ) ENGINE=[*]INNODB …
You have two problems here.
You cannot use ENGINE=InnoDB etc. in H2 unless MySQL or MariaDB compatibility mode was enabled, you need to append the related flags (;MODE=MySQL and possibly others) to JDBC URL:
https://h2database.com/html/features.html#compatibility
You also need to upgrade H2 to a more recent version, because old unsupported H2 1.4.200 is more restrictive here and cannot parse latin1 as charset name (or you can replace it with UTF8).
There is no such data types as STRING in H2 and in the real MySQL too, you need to use some valid data type, for example, VARCHAR(100).
