Mervyn Lobo updated SPARK-56611:
--------------------------------
Description:
h3. Problem
{{ALTER TABLE ... RENAME TO}} fails in these cases:
* Catalog-qualified targets in V2 (catalog incorrectly treated as namespace)
* Table-only targets (namespace not inherited from source)
Example:
{{ALTER TABLE testcat.ns.t1 RENAME TO testcat.ns.t2;}}
Produces incorrect identifier:
{{Identifier.of(["testcat", "ns"], "t2")}}
Expected:
{{Identifier.of(["ns"], "t2")}}
h3. Expected behaviour
* Strip catalog when it matches source
* Inherit source namespace for table-only targets
* Reject cross-namespace renames
h3. To Reproduce
{{CREATE TABLE testcat.ns.t1 USING foo AS SELECT 1 AS id;}}
{{{{}}{}}}{{{}ALTER TABLE testcat.ns.t1 RENAME TO testcat.ns.t2;{}}}{{{{}}{}}}
