The RENAME SYNONYM statement (rename_synonym_statement) changes the name of a synonym.
Syntax
<rename_synonym_statement> ::= RENAME [PUBLIC] SYNONYM <old_synonym_name> TO <new_synonym_name> <old_synonym_name> ::= <synonym_name> <new_synonym_name> ::= <synonym_name>
The old synonym name old_synonym_name must have been generated by the current database user.
If PUBLIC is specified, the old synonym must be defined as PUBLIC.
A table of the current database user with the new synonym name (new_synonym_name) must not exist already.
