Question

I’m trying to have a look at the tables generated in h2 db used in Grails project, but something’s amiss.

I connect to the browser console at http://127.0.1.1:8082/ but all that’s there to browse is INFORMATION_SCHEMA and Users. How do I get tho the tables used/generated by the app?

Just started building out the app and only few domain classes are in place and I’m trying to get a feel for working h2. Prior to that I’ve been using PostgreSql in all projects so this is very unnerving for the moment.
Thanks in advance

Answer 1

Are you using the right JDBC URL when logging in?

The default in grails is jdbc:h2:mem:devDB.

When an non-existing URL is given, like jdbc:h2:blabla, an empty database is created, with the default INFORMATION_SCHEMA and Users as you described.

Make sure you connect to the URL where your grails application stores its tables. You can find the URL in $GRAILS_PROJECT/config/DataSource.groovy, after the url definition.

environments {
  development {
    dataSource {
      pooled = false
      logSql = false
      username = "sa"
      password = ""

      dialect = "com.hp.opr.hibernate.dialect.H2Dialect"
      driverClassName = "org.h2.Driver"
      dbCreate = "create-drop"
      url = "jdbc:h2:mem:devDB;DB_CLOSE_DELAY=-1;MVCC=TRUE"
    }
  }
}
