Question

I have a SQL script with database dump. How can I execute it using Hibernate’s EntityManager?

I tried it this way:

EntityManager manager = getEntityManager(); 
Query q = manager.createNativeQuery(sqlScript);
q.executeUpdate();

but it works only when sqlScript contains a single SQL query, while I need to run multiple inserts and other complex stuff.

RDBMS:
Oracle Database 11g Express Edition Release 11.2.0.2.0 – 64bit Production

Wrap your query with begin end block. Like

EntityManager manager = getEntityManager(); 
Query q = manager.createNativeQuery("BEGIN " + sqlScript + " END;");
q.executeUpdate();
