Examples with ADD io.trino.spi.function.OperatorType.ADD used on opensource projects

Example 1 with ADD

use of io.trino.spi.function.OperatorType.ADD in project trino by trinodb.

the class DecimalOperators method decimalAddOperator.

private static SqlScalarFunction decimalAddOperator() {
    TypeSignature decimalLeftSignature = new TypeSignature("decimal", typeVariable("a_precision"), typeVariable("a_scale"));
    TypeSignature decimalRightSignature = new TypeSignature("decimal", typeVariable("b_precision"), typeVariable("b_scale"));
    TypeSignature decimalResultSignature = new TypeSignature("decimal", typeVariable("r_precision"), typeVariable("r_scale"));
    Signature signature = Signature.builder().operatorType(ADD).longVariableConstraints(longVariableExpression("r_precision", "min(38, max(a_precision - a_scale, b_precision - b_scale) + max(a_scale, b_scale) + 1)"), longVariableExpression("r_scale", "max(a_scale, b_scale)")).argumentTypes(decimalLeftSignature, decimalRightSignature).returnType(decimalResultSignature).build();
    return new PolymorphicScalarFunctionBuilder(DecimalOperators.class).signature(signature).deterministic(true).choice(choice -> choice.implementation(methodsGroup -> methodsGroup.methods("addShortShortShort").withExtraParameters(DecimalOperators::calculateShortRescaleParameters)).implementation(methodsGroup -> methodsGroup.methods("addShortShortLong", "addLongLongLong", "addShortLongLong", "addLongShortLong").withExtraParameters(DecimalOperators::calculateLongRescaleParameters))).build();
}

Example 2 with ADD

use of io.trino.spi.function.OperatorType.ADD in project trino by trinodb.

the class TestPolymorphicScalarFunction method testSetsHiddenToTrueForOperators.

@Test
public void testSetsHiddenToTrueForOperators() {
    Signature signature = Signature.builder().operatorType(ADD).returnType(new TypeSignature("varchar", typeVariable("x"))).argumentTypes(new TypeSignature("varchar", typeVariable("x"))).build();
    SqlScalarFunction function = new PolymorphicScalarFunctionBuilder(TestMethods.class).signature(signature).deterministic(true).choice(choice -> choice.implementation(methodsGroup -> methodsGroup.methods("varcharToVarchar"))).build();
    BoundSignature boundSignature = new BoundSignature(signature.getName(), createVarcharType(INPUT_VARCHAR_LENGTH), ImmutableList.of(createVarcharType(INPUT_VARCHAR_LENGTH)));
    function.specialize(boundSignature, new FunctionDependencies(FUNCTION_MANAGER::getScalarFunctionInvoker, ImmutableMap.of(), ImmutableSet.of()));
