Examples with ArithmeticBinaryExpression io.confluent.ksql.execution.expression.tree.ArithmeticBinaryExpression used on opensource projects

Example 36 with ArithmeticBinaryExpression

use of io.confluent.ksql.execution.expression.tree.ArithmeticBinaryExpression in project ksql by confluentinc.

the class ExpressionParserTest method shouldParseExpression.

@Test
public void shouldParseExpression() {
    // When:
    final Expression parsed = ExpressionParser.parseExpression("1 + 2");
    // Then:
    assertThat(parsed, equalTo(new ArithmeticBinaryExpression(parsed.getLocation(), Operator.ADD, ONE, TWO)));
}

Example 37 with ArithmeticBinaryExpression

use of io.confluent.ksql.execution.expression.tree.ArithmeticBinaryExpression in project ksql by confluentinc.

the class PartitionByParamsFactoryTest method shouldAppendNewKeyColumnToValueIfPartitioningByKeyExpression.

@Test
public void shouldAppendNewKeyColumnToValueIfPartitioningByKeyExpression() {
    // Given:
    final Mapper<GenericKey> mapper = partitionBy(ImmutableList.of(new ArithmeticBinaryExpression(Operator.ADD, new UnqualifiedColumnReferenceExp(COL0), new StringLiteral("-foo")))).getMapper();
    final ImmutableList<Object> originals = ImmutableList.copyOf(value.values());
    // When:
    final KeyValue<GenericKey, GenericRow> result = mapper.apply(key, value);
    // Then:
    assertThat(result.value, is(GenericRow.fromList(originals).append(OLD_KEY + "-foo")));
