Examples with SqlDecimal io.confluent.ksql.schema.ksql.types.SqlDecimal used on opensource projects

Example 1 with SqlDecimal

use of io.confluent.ksql.schema.ksql.types.SqlDecimal in project ksql by confluentinc.

the class DecimalUtilTest method shouldWidenIntAndDecimal.

@Test
public void shouldWidenIntAndDecimal() {
    // Given:
    final SqlDecimal smallerPrecision = SqlTypes.decimal(4, 3);
    final SqlDecimal largerPrecision = SqlTypes.decimal(11, 0);
    // Then:
    assertThat(DecimalUtil.widen(smallerPrecision, SqlTypes.INTEGER), is(SqlTypes.decimal(13, 3)));
    assertThat(DecimalUtil.widen(SqlTypes.INTEGER, largerPrecision), is(SqlTypes.decimal(11, 0)));
}

Example 2 with SqlDecimal

use of io.confluent.ksql.schema.ksql.types.SqlDecimal in project ksql by confluentinc.

the class DecimalUtilTest method shouldAllowImplicitlyCastOnHigherScale.

@Test
public void shouldAllowImplicitlyCastOnHigherScale() {
    // Given:
    final SqlDecimal s1 = SqlTypes.decimal(2, 1);
    final SqlDecimal s2 = SqlTypes.decimal(2, 2);
    // When:
    final boolean compatible = DecimalUtil.canImplicitlyCast(s1, s2);
    // Then:
    assertThat(compatible, is(false));
}

Example 3 with SqlDecimal

    final SqlDecimal s1 = SqlTypes.decimal(5, 2);
    final SqlDecimal s2 = SqlTypes.decimal(6, 3);
    // When:
    final boolean compatible = DecimalUtil.canImplicitlyCast(s1, s2);
    // Then:
    assertThat(compatible, is(true));
}

    when(visitor.visitDecimal(any())).thenReturn("Expected");
    // When:
    final String result = SqlTypeWalker.visit(type, visitor);
    // Then:
    verify(visitor).visitDecimal(same(type));
    assertThat(result, is("Expected"));
}

Example 5 with SqlDecimal

use of io.confluent.ksql.schema.ksql.types.SqlDecimal in project ksql by confluentinc.

the class DecimalUtil method widen.

/**
 * Return a {@link SqlDecimal} wide enough to hold either the {@code t0} or {@code t1} types.
 *
 * <p>Both sides must support implicit casting to {@link SqlDecimal}.
 *
 * @param t0 the first type
 * @param t1 the second type
 * @return a type wide enough to hold either type.

    final SqlDecimal lDecimal = DecimalUtil.toSqlDecimal(t0);
    final SqlDecimal rDecimal = DecimalUtil.toSqlDecimal(t1);
    final int wholePrecision = Math.max(lDecimal.getPrecision() - lDecimal.getScale(), rDecimal.getPrecision() - rDecimal.getScale());
    final int scale = Math.max(lDecimal.getScale(), rDecimal.getScale());
