Comma-delimited listsA comma-delimited list (or "list" for short) is a list of items, delimited with commas like this: Harry,Ron,HermioneLists are useful in storing sets or groups. They can serve some of the same purposes that arrays serve in other languages. In databases, lists can conveniently provide a degree of vectorization without requiring a separate table and joins. Lists can be a powerful approach-- the infamous programming language LISP made great use of lists. There are a number of functions for working with lists. Lists can be used...
Since the total length of a comma-delimited list is limited to about 250 characters,
lists are most suitable where individual values are known to be small in size
(such as controlled-vocabulary tags or integer id numbers) and where it is known that
there will not be a huge number of choices.
List members can not contain embedded commas, and there is no provision for escaping a comma.
List members can contain embedded spaces in some situations.
