  • Note: for Linux, you need at least sqlite > 3.6.1 installed

• List of Management Tools for SQLite: you can run queries, navigate through the database, etc.

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!
