Setting user_version in sqlite

Question

I have seen other questions on here about reading the user_version, and that seems to be working fine for me. However I\'m trying to use sqlite in FMDB to set my version nu

I was about to post a bounty when I figured out the issue. And as often happens, I was just being a bonehead

I was doing executeQuery where I should have been doing executeUpdate

_db = [self openDatabase];
[_db executeUpdate:[StudentController creationString]];
[_db executeUpdate:[ReadingController creationString]];
[_db executeUpdate:[SessionController creationString]];
NSLog(@"User version is %i", userVersion);
NSString *query = [NSString stringWithFormat:@"PRAGMA USER_VERSION = %i", userVersion];
[_db executeQuery:query];

should instead be:

_db = [self openDatabase];
[_db executeUpdate:[StudentController creationString]];
[_db executeUpdate:[ReadingController creationString]];
[_db executeUpdate:[SessionController creationString]];
NSLog(@"User version is %i", userVersion);
NSString *query = [NSString stringWithFormat:@"PRAGMA USER_VERSION = %i", userVersion];
[_db executeUpdate:query];

executing a Pragma is NOT a query, executeQuery doesn't do anything with it. It is instead in the same category as UPDATE, INSERT, and DELETE.
