Finishing implementation of sql-backend for datebook. But I have to

port the PIM datebook application to use it, before I could debug the
whole stuff.
Thus, PIM-Database backend is finished, but highly experimental. And some
parts are still generic. For instance, the "queryByExample()" methods are
not (or not fully) implemented. Todo: custom-entries not stored.
The big show stopper: matchRegExp() (needed by OpieSearch) needs regular
expression search in the database, which is not supported by sqlite !
Therefore we need either an extended sqlite or a workaround which would
be very slow and memory consuming..

  * Revision 1.8  2003/09/22 14:31:16  eilers
  * Added first experimental incarnation of sql-backend for addressbook.
  * Some modifications to be able to compile the todo sql-backend.
  * A lot of changes fill follow...
  *
  * Revision 1.7  2003/08/01 12:30:16  eilers
  * Merging changes from BRANCH_1_0 to HEAD
  *
  * Revision 1.6.4.1  2003/06/30 14:34:19  eilers
  * Patches from Zecke:
  * Fixing and cleaning up extraMap handling
  * Adding d_ptr for binary compatibility in the future
  *
  * Revision 1.6  2003/04/13 18:07:10  zecke
  * More API doc
  * QString -> const QString&
  * QString = 0l -> QString::null
  *
  * Revision 1.5  2003/02/21 23:31:52  zecke
  * Add XML datebookresource
  * -clean up todoaccessxml header
  * -implement some more stuff in the oeven tester
  * -extend DefaultFactory to not crash and to use datebook
  *
  * -reading of OEvents is working nicely.. saving will be added
  *  tomorrow
  *  -fix spelling in ODateBookAcces
  *
  * Revision 1.4  2002/10/14 15:55:18  eilers
  * Redeactivate SQL.. ;)
  *
  * Revision 1.3  2002/10/10 17:08:58  zecke
  * The Cache is finally in place
  * I tested it with my todolist and it 'works' for 10.000 todos the hits are awesome ;)
  * The read ahead functionality does not make sense for XMLs backends because most of the stuff is already in memory. While using readahead on SQL makes things a lot faster....
  * I still have to fully implement read ahead
  * This change is bic but sc
  *
  * Revision 1.2  2002/10/08 09:27:36  eilers
  * Fixed libopie.pro to include the new pim-API.
  * The SQL-Stuff is currently deactivated. Otherwise everyone who wants to
  * compile itself would need to install libsqlite, libopiesql...
  * Therefore, the backend currently uses XML only..
  *
  * Revision 1.1  2002/10/07 17:35:01  eilers
  * added OBackendFactory for advanced backend access
  *

  * History:
  * $Log$
+ * Revision 1.2  2003/12/22 10:19:26  eilers
+ * Finishing implementation of sql-backend for datebook. But I have to
+ * port the PIM datebook application to use it, before I could debug the
+ * whole stuff.
+ * Thus, PIM-Database backend is finished, but highly experimental. And some
+ * parts are still generic. For instance, the "queryByExample()" methods are
+ * not (or not fully) implemented. Todo: custom-entries not stored.
+ * The big show stopper: matchRegExp() (needed by OpieSearch) needs regular
+ * expression search in the database, which is not supported by sqlite !
+ * Therefore we need either an extended sqlite or a workaround which would
+ * be very slow and memory consuming..
+ *
  * Revision 1.1  2003/12/08 15:18:12  eilers
  * Committing unfinished sql implementation before merging to libopie2 starts..

  * ToDo: Define enum for query settings
  * =====================================================================
  * Version: $Id$
  * =====================================================================
  * History:
  * $Log$
+ * Revision 1.10  2003/12/22 10:19:26  eilers
+ * Finishing implementation of sql-backend for datebook. But I have to
+ * port the PIM datebook application to use it, before I could debug the
+ * whole stuff.
+ * Thus, PIM-Database backend is finished, but highly experimental. And some
+ * parts are still generic. For instance, the "queryByExample()" methods are
+ * not (or not fully) implemented. Todo: custom-entries not stored.
+ * The big show stopper: matchRegExp() (needed by OpieSearch) needs regular
+ * expression search in the database, which is not supported by sqlite !
+ * Therefore we need either an extended sqlite or a workaround which would
+ * be very slow and memory consuming..
+ *
  * Revision 1.9  2003/08/01 12:30:16  eilers
  * Merging changes from BRANCH_1_0 to HEAD
  *
  * Revision 1.8.2.1  2003/06/30 14:34:19  eilers
  * Patches from Zecke:
  * Fixing and cleaning up extraMap handling
  * Adding d_ptr for binary compatibility in the future
  *
  * Revision 1.8  2003/05/08 13:55:09  tille
  * search stuff
  * and match, toRichText & toShortText in oevent
  *
  * Revision 1.7  2003/04/13 18:07:10  zecke
  * More API doc
  * QString -> const QString&
  * QString = 0l -> QString::null
  *
  * Revision 1.6  2003/01/02 14:27:12  eilers
  * Improved query by example: Search by date is possible.. First step
  * for a today plugin for birthdays..
  *
  * Revision 1.5  2002/11/13 14:14:51  eilers
  * Added sorted for Contacts..
  *
  * Revision 1.4  2002/11/01 15:10:42  eilers
  * Added regExp-search in database for all fields in a contact.
  *
  * Revision 1.3  2002/10/16 10:52:40  eilers
  * Added some docu to the interface and now using the cache infrastucture by zecke.. :)
  *
  * Revision 1.2  2002/10/14 16:21:54  eilers
  * Some minor interface updates
  *
  * Revision 1.1  2002/09/27 17:11:44  eilers
  * Added API for accessing the Contact-Database ! It is compiling, but
  * please do not expect that anything is working !
  * I will debug that stuff in the next time ..
  * Please read README_COMPILE for compiling !
