-----------------------------------------
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}
