Example 1 with RoundDateExpression

use of org.apache.phoenix.expression.function.RoundDateExpression in project phoenix by apache.

the class RoundFloorCeilExpressionsTest method testRoundDateExpressionWithMultiplier.

@Test
public void testRoundDateExpressionWithMultiplier() throws Exception {
    Expression dateLiteral = LiteralExpression.newConstant(DateUtil.parseDate("2012-01-01 14:25:28"), PDate.INSTANCE);
    Expression roundDateExpression = RoundDateExpression.create(dateLiteral, TimeUnit.MINUTE, 10);
    ImmutableBytesWritable ptr = new ImmutableBytesWritable();
    roundDateExpression.evaluate(null, ptr);
    Object result = roundDateExpression.getDataType().toObject(ptr);
    assertTrue(result instanceof Date);
    Date resultDate = (Date) result;
    assertEquals(DateUtil.parseDate("2012-01-01 14:30:00"), resultDate);
}

Example 2 with RoundDateExpression
