It is true that triggers can be used to achieve referential integrity. However you don't have to hand craft them. The front page of the wiki links to the document explaining it: http://www.sqlite.org/cvstrac/wiki?p=ForeignKeyTriggers But the SQLite team has already done all the work for you. The SQLite source includes a program named 'genfkey' that will create the triggers. You can simply do: genfkey ./test.db | sqlite3 ./test.db Just run it again if you change your schema and it will drop the old triggers and supply new ones (by default). This is the README: http://www.sqlite.org/cvstrac/fileview?f=sqlite/tool/genfkey.README You can find the program in the tool subdirectory if you CVS checkout the SQLite code, or grab it using a browser from: http://www.sqlite.org/cvstrac/dir?d=sqlite/tool Roger -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkmTsjEACgkQmOOfHg372QSnQQCfUTQn0DaSwplXm/Gq8lSbAoXw eU0An1ygaYUSZhtifTz37fybb+A8MbBS =EUri -----END PGP SIGNATURE----- _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
