Examples with CriteriaQueryTranslator org.hibernate.loader.criteria.CriteriaQueryTranslator used on opensource projects

Example 1 with CriteriaQueryTranslator

use of org.hibernate.loader.criteria.CriteriaQueryTranslator in project hibernate-orm by hibernate.

the class SubqueryExpression method createAndSetInnerQuery.

/**
	 * Creates the inner query used to extract some useful information about types, since it is needed in both methods.
	 *
	 * @param criteriaQuery The criteria query
	 * @param factory The session factory.
	 */
private void createAndSetInnerQuery(CriteriaQuery criteriaQuery, SessionFactoryImplementor factory) {
    if (innerQuery == null) {
        //with two-deep subqueries, the same alias would get generated for
        //both using the old method (criteriaQuery.generateSQLAlias()), so
        //that is now used as a fallback if the main criteria alias isn't set
        String alias;
        if (this.criteriaImpl.getAlias() == null) {
            alias = criteriaQuery.generateSQLAlias();
        } else {
            alias = this.criteriaImpl.getAlias() + "_";
        }
        innerQuery = new CriteriaQueryTranslator(factory, criteriaImpl, criteriaImpl.getEntityOrClassName(), alias, criteriaQuery);
        params = innerQuery.getQueryParameters();
        types = innerQuery.getProjectedTypes();
    }
}

Example 2 with CriteriaQueryTranslator

use of org.hibernate.loader.criteria.CriteriaQueryTranslator in project hibernate-orm by hibernate.

the class CriterionTest method testIlikeRendering.

@Test

        final Criterion ilikeExpression = Restrictions.ilike("name", "abc");
        final String ilikeExpressionSqlFragment = ilikeExpression.toSqlString(criteria, translator);
        assertEquals("a.name insensitiveLike ?", ilikeExpressionSqlFragment);
    } finally {
        sf.close();
    }
}

        assertEquals("lowLowLow(a.name) like ?", ilikeExpressionSqlFragment);
    } finally {
        sf.close();
    }
