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

Example 1 with NotExpression

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

the class ExpressionTypeManagerTest method shouldEvaluateBooleanSchemaForNotLikeExpression.

@Test
public void shouldEvaluateBooleanSchemaForNotLikeExpression() {
    final Expression expression = new NotExpression(new LikePredicate(COL1, new StringLiteral("%foo"), Optional.empty()));
    final SqlType exprType0 = expressionTypeManager.getExpressionSqlType(expression);
    assertThat(exprType0, is(SqlTypes.BOOLEAN));
}

Example 2 with NotExpression

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

the class ExpressionTreeRewriterTest method shouldRewriteNotExpression.

@Test
public void shouldRewriteNotExpression() {
    // Given:
    final NotExpression parsed = parseExpression("NOT 1 < 2");
    when(processor.apply(parsed.getValue(), context)).thenReturn(expr1);
    // When:
    final Expression rewritten = expressionRewriter.rewrite(parsed, context);
    // Then:
    assertThat(rewritten, equalTo(new NotExpression(parsed.getLocation(), expr1)));
