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

Naming as described for tables.

Optionally suffixed by _tmp

Optionally prefixed by a project abbreviation.

Examples

  • employees_tmp
  • contracts_tmp
