The H2 in memory database is very convenient for development because your evolutions are run from scratch when play is restarted. If you are using anorm you probably need it to closely mimic your planned production database. To tell h2 that you want to mimic a particular database you add a parameter to the database url in your application.conf file, for example:
- H2 does not have a uuid() function. You can use random_uuid() instead. Or insert the following line into your 1.sql file:
CREATE ALIAS UUID FOR "org.h2.value.ValueUuid.getNewRandom";
- Text comparison in MySQL is case insensitive by default, while in H2 it is case sensitive (as in most other databases). H2 does support case insensitive text comparison, but it needs to be set separately, using SET IGNORECASE TRUE. This affects comparison using =, LIKE, REGEXP.
MS SQL MODE=MSSQLServer
H2 drops your database if there are no connections. You probably don’t want this to happen. To prevent this add
DB_CLOSE_DELAY=-1 to the url (use a semicolon as a separator) eg:
You can browse the contents of your database by typing
h2-browser at the play console. An SQL browser will run in your web browser.
More H2 documentation is available from their web site.
