use of org.apache.calcite.rel.metadata.RelColumnOrigin in project calcite by apache.

the class RelMetadataTest method checkTwoColumnOrigin.

// WARNING:  this requires the two table names to be different
private void checkTwoColumnOrigin(String sql, String expectedTableName1, String expectedColumnName1, String expectedTableName2, String expectedColumnName2, boolean expectedDerived) {
    Set<RelColumnOrigin> result = checkColumnOrigin(sql);
    assertTrue(result != null);
    assertEquals(2, result.size());
    for (RelColumnOrigin rco : result) {
        RelOptTable actualTable = rco.getOriginTable();
        List<String> actualTableName = actualTable.getQualifiedName();
        String actualUnqualifiedName = Iterables.getLast(actualTableName);
        if (actualUnqualifiedName.equals(expectedTableName1)) {
            checkColumnOrigin(rco, expectedTableName1, expectedColumnName1, expectedDerived);
        } else {
            checkColumnOrigin(rco, expectedTableName2, expectedColumnName2, expectedDerived);
        }
