Wildcard 1


Wildcard 1 : (ICT) A wild card is a symbol that means "Anything can match". It is used in database search queries. For example if you wanted to find all of the men in your database that had a surname starting with Sm, you could use the search term: Sm*. When you run the search, the database would return all records which started Sm... such as Smith, Smythe, Smallwood, Smethwick. If you don't remember the name of a document that you saved, you could use the wildcard to run a search such as *.doc. This would give you a list of every doc file, regardless of its name. A wild card is part of a family of search symbols called 'Regular Expressions'
