Example 46 with RequiresDialectFeature

use of org.hibernate.testing.RequiresDialectFeature in project hibernate-orm by hibernate.

the class ClobLocatorTest method testUnboundedClobLocatorAccess.

@Test

    // unsupported; most databases would not allow such a construct anyway.
    // Thus here we are only testing materialization...
