restrictions

see also http://www.sqlite.org/omitted.html

  • no access permissions (other than file permissions); this is not so much a problem, because we use our own tables for access permissions anyways
  • no sequences (need a workaround: use eg. http://www.sqlite.org/faq.html#q1 AUTOINCREMENT)
  • no foreign key constraints

purpose

SQLite is easy to install, and therefore is useful for setting up demo systems for evaluation of OpenPetra.org

tools

  • in PetraTools, see project SQLiteConsole;
    • this is a command line program that allows you to run SQL queries against your SQLite database, even when it is encrypted. I had problems finding a client that connects to our encrypted database on Windows. (On Linux, we cannot use encryption at the moment, so any other graphical SQLite client should work)

issues

  • on Linux, I have not figured out yet, which dll to use;
    • ManagedOnly.dll does not work with encryption, error: System.Data.SQLite.UnsafeNativeMethods:sqlite3_key; see also http://sqlite.phxsoftware.com/forums/p/1508/6579.aspx#6579
    • the other dll also does not run on Linux, even with sqlite3 = 3.6.10; System.Data.SQLite.UnsafeNativeMethods:sqlite3_open_interop
  • for the moment: it works with ManagedOnly.dll, and empty password; only use for testing and development, not for production mode!
