Example 1 with FilterCharScalarEqualStringGroupColumn

use of org.apache.hadoop.hive.ql.exec.vector.expressions.gen.FilterCharScalarEqualStringGroupColumn in project hive by apache.

the class TestVectorStringExpressions method testCharScalarCompareStringCol.

@Test
public // Test CHAR literal to string column comparison
void testCharScalarCompareStringCol() {
    VectorizedRowBatch batch = makeStringBatch();
    VectorExpression expr;
    expr = new FilterCharScalarEqualStringGroupColumn(new HiveChar(new String(red2), 8), 0);
    expr.evaluate(batch);
    // only red qualifies, and it's in entry 0
    Assert.assertTrue(batch.size == 1);
    Assert.assertTrue(batch.selected[0] == 0);
    batch = makeStringBatch();
    expr = new FilterCharScalarGreaterStringGroupColumn(new HiveChar(new String(red2), 8), 0);
    expr.evaluate(batch);
    // only green qualifies, and it's in entry 1
    Assert.assertTrue(batch.size == 1);
    Assert.assertTrue(batch.selected[0] == 1);
    batch = makeStringBatch();
    expr = new FilterCharScalarLessEqualStringGroupColumn(new HiveChar(new String(green), 10), 0);
    expr.evaluate(batch);
    // green and red qualify
    Assert.assertTrue(batch.size == 2);
    Assert.assertTrue(batch.selected[0] == 0);
    Assert.assertTrue(batch.selected[1] == 1);
