Sqlite3_step() keeps returning SQLITE_MISUSE on this query. Any pointers?

Question

I am trying to open a sqlite db in the viewDidLoad routine and trying to send a sql query through to the db, but the sqlite_step() fails every time. I am not sure what\'s wrong

Answer 1

Have you verified that the statement compiles OK? You have the success = sqlite3_prepare_v2(...); line, but never do anything if success is not SQLITE_OK. Have you verified that it is SQLITE_OK?

On the other hand, if you were to use a wrapper like FMDB, you could replace all of your code above with:

- (void)viewDidLoad {
    [super viewDidLoad];
    NSString *dbname = @"name.sqlite";
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *path = [documentsDirectory stringByAppendingPathComponent:dbname];
    FMDatabase * database = [FMDatabase databaseWithPath:path];

    [database executeUpdate:@"insert into name(nid, name) values(?, ?)", [NSNumber numberWithInt:6], @"testname"];
    [database close];
}

This, IMO, is much easier to debug.
