Maksim Zhuravkov updated IGNITE-19307:
--------------------------------------
Environment: (was: The following query fails with "Conversion to
relational algebra failed to preserve datatypes"
{code:java}
@Test
public void test() {
sql("CREATE TABLE tt (id integer primary key, test_key integer)");
sql("INSERT INTO tt VALUES(1, 100)");
assertQuery("SELECT test_key FROM tt UNION ALL SELECT '1000'").check();
}
{code}
Although the same expression with literal works as expected:
{code:java}
@Test
public void test2() {
assertQuery("SELECT 100 UNION ALL SELECT '1000'").check();
}
{code}
Error:
{code:java}
java.lang.AssertionError: Conversion to relational algebra failed to preserve
datatypes:
validated type:
RecordType(VARCHAR CHARACTER SET "UTF-8" NOT NULL TEST_KEY) NOT NULL
