public void testEvaluateCurrentSchemaNotSupported() throws Exception {
    expectedException.expect(UnsupportedOperationException.class);
    expectedException.expectMessage("Cannot evaluate CURRENT_SCHEMA function.");
    Function function = (Function) sqlExpressions.asSymbol("current_schema()");
    Scalar impl = (Scalar) functions.get(function.info().ident());
    impl.evaluate();
}

Example 2 with Function

use of io.crate.analyze.symbol.Function in project crate by crate.

the class EvaluatingNormalizerTest method testEvaluationClusterGranularity.

@Test
public void testEvaluationClusterGranularity() {
    EvaluatingNormalizer visitor = new EvaluatingNormalizer(functions, RowGranularity.CLUSTER, ReplaceMode.COPY, referenceResolver, null);
    Function op_or = prepareFunctionTree();
    Symbol query = visitor.normalize(op_or, transactionContext);
    assertThat(query, instanceOf(Function.class));
}

Example 3 with Function

use of io.crate.analyze.symbol.Function in project crate by crate.

the class EvaluatingNormalizerTest method testEvaluation.

@Test
public void testEvaluation() {
    EvaluatingNormalizer visitor = new EvaluatingNormalizer(functions, RowGranularity.NODE, ReplaceMode.MUTATE, referenceResolver, null);
    Function op_or = prepareFunctionTree();
    // the dummy reference load == 0.08 evaluates to true,
    // so the whole query can be normalized to a single boolean literal
    Symbol query = visitor.normalize(op_or, transactionContext);
    assertThat(query, isLiteral(true));
}

Example 4 with Function

use of io.crate.analyze.symbol.Function in project crate by crate.
