🆓Warning
Always follow naming conventions for collection type.
Reason
SQL identifiers share the same namespace as PL/SQL identifiers. Follow naming conventions to prevent naming conflicts, improve readability, and clearly indicate the scope without forcing the use of qualified names. A common practice is to use a prefix and/or suffix to distinguish the identifier types.
Recommendations
A collection type should include the name of the collected objects in their name. Furthermore, they should have the suffix _ct to identify it as a collection.
Optionally prefixed by a project abbreviation.
Examples
employees_ctorders_ct
