-------------------------------------
Fix Version/s: 2.19
> SQL Calcite: Fix CAST to VARCHAR for unmapped Java types
> --------------------------------------------------------
>
> Key: IGNITE-29129
> URL: https://issues.apache.org/jira/browse/IGNITE-29129
> Project: Ignite
> Issue Type: Bug
> Reporter: Kirill Tkalenko
> Assignee: Kirill Tkalenko
> Priority: Major
> Labels: calcite, ignite-2, sql
> Fix For: 2.19
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> A {{CAST}} to {{VARCHAR}} failure was found in the {{SYS.TABLE_COLUMNS}}
> system view. Unmapped Java types should use Ignite’s {{OtherType}} and
> support the same conversion as an explicit {{OTHER}} column:
> {code:java}
> CREATE TABLE T (ID INT PRIMARY KEY, VAL OTHER);
> INSERT INTO T VALUES (1, 'hello'), (2, 42), (3, NULL);
> SELECT ID, CAST(VAL AS VARCHAR)
> FROM T
> ORDER BY ID; {code}
> Expected results: {{{}(1, 'hello'){}}}, {{{}(2, '42'){}}}, {{{}(3, NULL){}}}.
> The system view failure became consistently reproducible after IGNITE-29045
> removed a type-cache collision.
