I have table somewhat like this created by sqlite 2.8.14:
create table t1( created timestamp not null, n int not null, url text not null, primary key(n) );
somehow i've ended up with a database where .dump t1 produces a bunch of
insert into t1 values(NULL,NULL,NULL);
a pragma integrity_check produces output like:
*** in database main *** On page 578 cell 0: Key is out of order On page 1204 cell 4: Key is out of order On page 1161 cell 2: Key is out of order On page 1210 cell 0: Key is out of order On page 1210 cell 6: Key is out of order rowid -500152523 missing from index (t1 autoindex 1) rowid -500152523 missing from index (t1 autoindex 1) rowid -500152523 missing from index (t1 autoindex 1) rowid -500152523 missing from index (t1 autoindex 1) rowid -500152523 missing from index (t1 autoindex 1) rowid -500152523 missing from index (t1 autoindex 1) rowid -500152523 missing from index (t1 autoindex 1) rowid -500152523 missing from index (t1 autoindex 1) rowid -500152523 missing from index (t1 autoindex 1) rowid -500152523 missing from index (t1 autoindex 1) rowid -500152523 missing from index (t1 autoindex 1) rowid -500152523 missing from index (t1 autoindex 1) rowid -500152523 missing from index (t1 autoindex 1) rowid -500152523 missing from index (t1 autoindex 1) rowid -500152523 missing from index (t1 autoindex 1) rowid -500152523 missing from index (t1 autoindex 1) wrong # of entries in index (t1 autoindex 1)
the number of missing rows == the number of NULL rows from the dump.
how does one get into this state where the contraints are ignored? If I were a guessing man, I'd say that space is being reserved and zeroed, but data is never being flushed to disk. Additionally, it seems that a journal file is either not being created, or is being deleted before the database is opened again, so that data is never recovered.
Has anyone seen anything like this and can suggest possible causes?
does your code fork?
