How to resolve synonym creation error in Oracle?

If you encounter an error while creating a synonym in Oracle, you can try the following solution:

1. Check permissions: Make sure you have the CREATE SYNONYM permission. You can use the following command to check if the current user has this permission:
2. Retrieve all records from the USER_SYS_PRIVS table where the PRIVILEGE is ‘CREATE SYNONYM’.
3. Check the naming of synonyms: Ensure that the names of synonyms do not conflict with other objects (such as tables, views, functions, etc.) and that the names do not use Oracle reserved words. Try creating synonyms using different names.
4. Check for the existence of objects: ensure that the referenced objects (tables, views, functions, etc.) exist and are in the correct schema. Use the following command to check if the objects exist:
5. Retrieve all objects from the database where the object’s name matches ‘object_name’.
6. Check mode qualifiers: Make sure that the correct mode qualifier is used when creating synonyms if the object is not in the current mode. For example, if the object is in SCHEMA_A, the syntax for creating a synonym should be:
7. Make a synonym called synonym_name for the object_name in schema A.
8. Check tablespace restrictions: Verify that the current user has sufficient privileges to access the tablespace if the synonym references objects in different tablespaces.
