What needs to happen?

Some features are missing:

• Support DDL for DATABASEs (create, use, drop) [Beam SQL] Support DATABASE concept in Beam SQL, with implementation for Iceberg #35641
• If a user has set a DATABASE, they should be able to read an existing table without having to run a redundant CREATE EXTERNAL TABLE... Implement a hierarchy for Beam SQL Calcite Schemas #35787
• If a user does not set a LOCATION property, we should infer the table name from the reference name Implement a hierarchy for Beam SQL Calcite Schemas #35787
  • If it's missing database information, we should infer that from the currently set DATABASE
• Support SHOW statements
  • SHOW CATALOGS
  • SHOW CURRENT CATALOG
  • SHOW DATABASES [ ( FROM | IN ) catalog_name] [ [NOT] LIKE <sql_like_pattern> ]
  • SHOW CURRENT DATABASE
  • SHOW TABLES [ ( FROM | IN ) [catalog_name.]database_name ] [ [NOT] LIKE <sql_like_pattern> ]
• Add Iceberg CDC table
• Support ALTER TABLE, CATALOG

For reference, Flink and Spark syntax
