无法创建嵌入式H2数据库

Question

I am using the web console of H2 Version 1.4.198 (2019-02-22) to create a embedded database. But I am getting the following error saying "unable to find the database". I want to create the database not open an existing one. I using ubuntu 18.04 and have given execute permisison to h2.jar and h2.sh.

Answer 1

In application.properties or yaml file check spring.datasource.url remove the flag IFEXISTS=TRUE;.

If the flag is set to true, the connection is only established if the database exists. For reference of the flag see http://www.h2database.com/html/features.html#database_only_if_exists

The application properties file should look like as below

application.properties

h2.datasource.driver-class-name=org.h2.Driver
h2.datasource.url=jdbc:h2:file:~/test;DB_CLOSE_ON_EXIT=TRUE;FILE_LOCK=NO
h2.datasource.username=sa
h2.datasource.password=

spring.h2.console.enabled=true
spring.h2.console.path=/h2-console/

It looks like as below (Test Connection is successful)

Answer 2

I get the same error with the latest ( 1.4.198 ) version. It works for me with the stable version - 1 .4.197 . @sagar-bahadur-tamang can you check your version and try suitably?
