Foreign key is (basename,md5sum,size). Your example shows that a composite key in this case is possible, but it is not appropriate. Use simple key md5sum. Make two tables. Attribute "size" (part of primary key) is redundant. -- Kit _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
