Outputs the results of a query on a SQLite_ Database as a tabular file.

In addition to the standard SQLite_functions_ regular_expression_ functions are included.

For example, with SQLite table "customers":

    =========== ========== ========== ===================== ========== ============
    #CustomerID FirstName  LastName   Email                 BirthDate  Phone
    =========== ========== ========== ===================== ========== ============
    1           John       Smith      John.Smith@yahoo.com  1968-02-04 626 222-2222
    2           Steven     Goldfish   goldfish@fishhere.net 1974-04-04 323 455-4545
    3           Paula      Brown      pb@herowndomain.org   1978-05-24 416 323-3232
    4           James      Smith      jim@supergig.co.uk    1980-10-20 416 323-8888
    =========== ========== ========== ===================== ========== ============

  ::

    matching:      re_match('pattern',column)

    SELECT FirstName, LastName
    FROM customers
    WHERE re_match('^.*\.(net|org)$',Email)

  Results:

    =========== ==========
    #FirstName  LastName
    =========== ==========
    Steven      Goldfish
    Paula       Brown
    =========== ==========


  ::

    searching:     re_search('pattern',column)
    substituting:  re_sub('pattern','replacement,column)

    SELECT FirstName, LastName, re_sub('^\d{2}(\d{2})-(\d\d)-(\d\d)','\3/\2/\1',BirthDate) as "DOB"
    FROM customers
    WHERE re_search('[hp]er',Email)

  Results:

    =========== ========== ==========
    #FirstName  LastName   DOB
    =========== ========== ==========
    Steven      Goldfish   04/04/74
    Paula       Brown      24/05/78
    James       Smith      20/10/80
    =========== ========== ==========
