Entry, deletion
With relations, you can use a wildcard (@) anywhere in the foreign key to display the records of the primary keys. Here are some examples:
- ab@ = shows all records starting with "ab"
- @ab = shows all records ending with "ab"
- @ab@ = shows all records containing "ab"
- @a@b@ = shows all records containing "a" and containing "b" ("a" first and then "b" next)
