  -== Recommended reading
  -
  -Here is some recommended reading on understanding SQL in depth.
  - +
  - +
  -SQL: The Complete Reference, 3rd Edition, James R. Groff, Paul
  -N. Weinberg, Andrew J. Oppel
  -
  -This is a comprehensive book which covers up to the SQL:1999 standard.
  - +
  - +
  - +
  -SQL in a Nutshell, Kevin Kline, Brand Hunt, Daniel Kline
  -
  -This is another good book which covers some of the SQL:2003 and
  -SQL:2008 standards. This means it covers a few newer things like
  -window functions which 'SQL: The Complete Reference' doesn't. It also
  -compares some main SQL product dialects.
  - +
  - +
  - +
  -SQL A Comparative Survey, Hugh Darwen +
  -http://bookboon.com/en/sql-a-comparative-survey-ebook
  -
  -This is a book about SQL from a relational theory perspective.
  - +
  - +
  - +
  -SQL and Relational Theory, 2nd Edition, Chris Date
  -
  -This also covers SQL from a partly theoretical perspective.
  - +
  - +
  - +
  -A Guide to the SQL Standard, C. J. Date, Hugh Darwen
  -
  -This is a fantastic book for covering all the little details of the
  -SQL standard in depth. It only covers up to SQL:92.
  - +
  - +
  - +
  -There are several other good books by Chris Date, some with Hugh
  -Darwen and others, for instance 'Introduction to Database Systems',
  -'Temporal Data & the Relational Model, Databases', 'Types and the
  -Relational Model'. Only the first one (Introduction to
  -Database Systems) really relates to SQL.
  - +
  - +
  - +
  -Database Systems: The Complete Book, Hector Garcia-Molina, Jeff Ullman, and Jennifer Widom.
  -
  -This book is very comprehensive and has some interesting sections.
  - +
  - +
  - +
  -Some of the SQL draft standards are available to download for free (follow the
  -links on the wikipedia page for SQL). They are a little tricky to
  -read and understand. You can find some stuff at these links.

positive.code: likely to change the abstract syntax types considerably.
  
  Tested with GHC 7.10.2, 7.8.4 and 7.6.3.

negative.code: queries, plus a good subset of DDL, non-query DML, transaction
  management, access control and session management.

  versions is available here:

  Status: covers a lot of queries already, but the public API is
  probably not very stable, since adding support for all the
