> Key: IGNITE-19307
> URL: https://issues.apache.org/jira/browse/IGNITE-19307
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Environment: The following query fails with "Conversion to relational
> algebra failed to preserve datatypes"
> {code:java}
> @Test

> 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:

> assertQuery("SELECT 100 UNION ALL SELECT '1000'").check();
> }
> {code}
> Error:
> {code:java}
