Examples with DecimalScalarModuloDecimalColumn org.apache.hadoop.hive.ql.exec.vector.expressions.gen.DecimalScalarModuloDecimalColumn used on opensource projects

Example 1 with DecimalScalarModuloDecimalColumn

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

the class TestVectorArithmeticExpressions method testDecimalScalarModuloDecimalColumn.

// Spot check decimal scalar-column modulo
@Test
public void testDecimalScalarModuloDecimalColumn() throws HiveException {
    VectorizedRowBatch b = getVectorizedRowBatch3DecimalCols();
    HiveDecimal d = HiveDecimal.create("2.00");
    VectorExpression expr = new DecimalScalarModuloDecimalColumn(d, 0, 2);
    // test without nulls
    expr.evaluate(b);
    DecimalColumnVector r = (DecimalColumnVector) b.cols[2];
    assertTrue(r.vector[0].getHiveDecimal().equals(HiveDecimal.create("0.80")));
    assertTrue(r.vector[1].getHiveDecimal().equals(HiveDecimal.create("2.00")));
    // entry 2 will be null due to zero-divide
    assertFalse(r.noNulls);
    assertTrue(r.isNull[2]);
    // try again with some different data values
    DecimalColumnVector in = (DecimalColumnVector) b.cols[0];
    expr = new DecimalScalarModuloDecimalColumn(d, 0, 2);
