Example 6 with JoinPredicate

use of org.teiid.query.sql.lang.JoinPredicate in project teiid by teiid.

the class TestJoinPredicate method testNonEquivalence3.

/**
 * Test a <code>JoinPredicate</code> object using <code>UnitTestUtil.helpTestEquivalence</code>.
 * <p>
 * This test ensures that two different <code>JoinPredicate</code> objects
 * constructed with different join types but with the same criteria evaluate
 * as not equal.

 * For example:
