I'm using DBI to query a SQLite3 database. What I have works, but it doesn't return the columns in order.

(values and columns are just for illustration) I know this i...
I made a model, and ran python manage.py syncdb. I think that created a table in the db. Then I realized that I had made a column incorrectly, so I changed it, and ran the same command, thinking that it would drop the old table, and add a new one. Then I went to python manage.py shell, and tried to run .objects.all(), and it failed, say...

I am looking at a SQLite database owned by a third party process. It appears locked and has a *-journal file. What I don't know, is if the lock is shared or exclusive.

I'm experiencing a very strange issue with string equality in SQLite3. I have a table with a text column named type. If I run select distinct type, 2 from mytable order by type (the 2 is there to get the pipe separator), I get: ... Tops|2 ... Tops|2 i.e., the same column appears twice. This is causing me problems because queries wi...

Hi, I'm an iPhone developer. I'm writing my unit test cases, one of which checks if the app accepts UTF8 strings to be written to a sqlite3 database. I created a test case to generate random UTF8 strings and I can see the ones that fail do so because they contain an apostrophe (') which I need to be accepted. I'm writing to the databa...
