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

Example 1 with IsNotNullPredicate

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

the class ExpressionTreeRewriterTest method shouldRewriteIsNotNullPredicate.

@Test
public void shouldRewriteIsNotNullPredicate() {
    // Given:
    final IsNotNullPredicate parsed = parseExpression("col0 IS NOT NULL");
    when(processor.apply(parsed.getValue(), context)).thenReturn(expr1);
    // When:
    final Expression rewritten = expressionRewriter.rewrite(parsed, context);
    // Then:
    assertThat(rewritten, equalTo(new IsNotNullPredicate(parsed.getLocation(), expr1)));
}

Example 2 with IsNotNullPredicate

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

the class InterpretedExpressionTest method shouldEvaluateIsNotNullPredicate.

@Test
public void shouldEvaluateIsNotNullPredicate() {
    // Given:
    final Expression expression1 = new IsNotNullPredicate(COL11);
    final Expression expression2 = new IsNotNullPredicate(new NullLiteral());
    // When:
    InterpretedExpression interpreter1 = interpreter(expression1);
    InterpretedExpression interpreter2 = interpreter(expression2);
    // Then:
    assertThat(interpreter1.evaluate(make(11, true)), is(true));
    assertThat(interpreter1.evaluate(make(11, null)), is(false));
    assertThat(interpreter2.evaluate(ROW), is(false));
