-----------------------------------------

             Summary: Sql. Migrate to calcite's UUID
                 Key: IGNITE-25091
                 URL: https://issues.apache.org/jira/browse/IGNITE-25091
             Project: Ignite
          Issue Type: Improvement
          Components: sql
            Reporter: Maksim Zhuravkov


Calcite 1.39 introduced the UUID data type (difference with Apache Ignite's UUID):
* It has its own literal (does not work, there is no RexLiteral for UUID yet)
* It support implicit casts to CHAR/BINARY types and vice versa.

These examples work in vanilla calcite (SqlValidatorTest):

{noformat}
    sql("SELECT CAST(UUID '10000000-2000-3000-4000-500000000000' as varbinary)").ok();
    sql("SELECT CAST(col as UUID) FROM ( VALUES (x'00') ) t(col)").ok();
    sql("SELECT CASE WHEN 1 > 0 THEN UUID '10000000-2000-3000-4000-500000000000' ELSE col END FROM ( VALUES (x'00') ) t(col)").ok();
{noformat}
