Example 1 with IfExprDoubleColumnDoubleScalar

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

the class TestVectorConditionalExpressions method testDoubleColumnScalarIfExpr.

@Test
public void testDoubleColumnScalarIfExpr() throws HiveException {
    VectorizedRowBatch batch = getBatch1Long3DoubleVectors();
    VectorExpression expr = new IfExprDoubleColumnDoubleScalar(0, 1, 200d, 3);
    DoubleColumnVector r = (DoubleColumnVector) batch.cols[3];
    expr.evaluate(batch);
    assertEquals(true, 200d == r.vector[0]);
    assertEquals(true, 200d == r.vector[1]);
    assertEquals(true, -3d == r.vector[2]);
    assertEquals(true, -4d == r.vector[3]);

Example 2 with IfExprDoubleColumnDoubleScalar

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

the class TestVectorizationContext method testIfConditionalExprs.

/**
 * Test that correct VectorExpression classes are chosen for the
 * IF (expr1, expr2, expr3) conditional expression for integer, float,
 * boolean, timestamp and string input types. expr1 is always an input column expression
 * of type long. expr2 and expr3 can be column expressions or constants of other types
 * but must have the same type.
