Example 11 with AggregateFunction

use of io.trino.spi.connector.AggregateFunction in project trino by trinodb.

the class TestSqlServerClient method testImplementCount.

@Test
public void testImplementCount() {
    Variable bigintVariable = new Variable("v_bigint", BIGINT);
    Variable doubleVariable = new Variable("v_double", BIGINT);
    Optional<ConnectorExpression> filter = Optional.of(new Variable("a_filter", BOOLEAN));
    // count(*)
    testImplementAggregation(new AggregateFunction("count", BIGINT, List.of(), List.of(), false, Optional.empty()), Map.of(), Optional.of("count_big(*)"));
    // count(bigint)
    testImplementAggregation(new AggregateFunction("count", BIGINT, List.of(bigintVariable), List.of(), false, Optional.empty()), Map.of(bigintVariable.getName(), BIGINT_COLUMN), Optional.of("count_big(\"c_bigint\")"));
