Research direction
Locate the SQL parser code that handles the 'CONVERT PARTITION' clause, likely in files like SqlParser.java or similar. Examine how the singular 'partition' token is currently processed and add support for the plural 'partitions'. Look for any existing grammar rules or keyword definitions that might need updating. The issue is straightforward: simply accept an alternative keyword. No additional logic changes are required.
