H2 file embedded mode runscript on creating db(not initializing connection)

Question

I need to create H2 file db on demand(first connection) from backup-ed script. As I understand it could be done only by using two different urls:

• jdbc:h2:file:sampledb;INIT=RUNSCRIPT FROM 'create.sql'; (Should be executed only one time)

• jdbc:h2:file:sampledb;IFEXISTS=TRUE;

The problem is that in application connection to db is coming from JNDI so I should set up only one correct url. Does any ability exist to specify parameters based on some condition? And how to get this conditionn from H2? (Something like jdbc:h2:file:sampledb;!{dbixists}=runscript...). Or some ternary operation is allowed?

Answer 1

I would simply include IF NOT EXIST clauses inside the create.sql script and run it everytime. It would create the DB model only if there is no proper model at all.
