Vladimir Steshin updated IGNITE-23308:
--------------------------------------
Release Note: Fixed incorrect result in unions in case of different types
of numeric results.
> Calcite. Wrong numeric type coercion with set-op operations.
> ------------------------------------------------------------
>
> Key: IGNITE-23308
> URL: https://issues.apache.org/jira/browse/IGNITE-23308
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.14
> Reporter: Vladimir Steshin
> Priority: Major
> Labels: calcite, ignite-2, ise
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Wrong numers cast with operators like _UNION_ / _INTERSECT_ / EXCEPT.
> Reproducer:
> {code:java}
> public void testUnionWithNumerics() {
> sql("CREATE TABLE t0(id INT PRIMARY KEY, val INT)");
> sql("CREATE TABLE t1(id INT PRIMARY KEY, val DECIMAL)");
> sql("INSERT INTO t0 VALUES (1, 10)");
> sql("INSERT INTO t1 VALUES (1, 10)");
> assertQuery(ignite(0), "SELECT val from t0 UNION select val from t1")
> .returns(new BigDecimal(10))
> .ordered()
> .check();
> }
> {code}
> Error:
> {code:java}
> java.lang.AssertionError: Collections sizes are not equal:
> Expected: [[10]]
> Actual: [[10], [10]]
> {code}
> Or:
> {code:java}
> public void testIntersectWithNumerics() {
> sql("CREATE TABLE t0(id INT PRIMARY KEY, val INT)");
> sql("CREATE TABLE t1(id INT PRIMARY KEY, val DECIMAL)");
> sql("INSERT INTO t0 VALUES (1, 10), (2, 20), (3, 30), (4, 40), (5,
> 50)");
> sql("INSERT INTO t1 VALUES (1, 10), (2, 20), (3, 300), (4, 400), (5,
> 50)");
> assertQuery(ignite(0), "SELECT val from t0 INTERSECT select val from
> t1")
> .returns(new BigDecimal(10))
> .returns(new BigDecimal(20))
> .returns(new BigDecimal(50))
> .ordered()
> .check();
> }
> {code}
> Error:
> {code:java}
> java.lang.AssertionError: Collections sizes are not equal:
> Expected: [[10], [20], [50]]
> Actual: []
> {code}
> Adoption of #IGNITE-21827 and #IGNITE-20649
