Sqlite insert statement will not put a record in the table - objective-c

Question

Everything in this function seems to work as expected, just no record actually shows up in the database table. If I enter the sql directly through the Firefox sqlite manager plugin, the record appears just fine. Probably something frustratingly stupid, any ideas?
- (IBAction)buttonInsertRecord:(id)sender
{
// initializing db file access
NSFileManager *fileMgr = [NSFileManager defaultManager];
NSString *dbPath = [[[NSBundle mainBundle] resourcePath ]stringByAppendingPathComponent:#"KJV.sqlite"];
// testing to see if database was found
BOOL success = [fileMgr fileExistsAtPath:dbPath];
if(!success)
{
// database not found
labelStatus.text = #"database not found";
}
else
{
// database not found
labelStatus.text = #"database found";
}
sqlite3_stmt *statement;
sqlite3 *dbPointer;
if (sqlite3_open(dbPath.UTF8String, &dbPointer) == SQLITE_OK)
{
NSString *insertSQL = [NSString stringWithFormat: #"INSERT INTO users (user_name, user_id) VALUES ('testuser', null);"];
const char *insert_stmt = [insertSQL UTF8String];
sqlite3_prepare_v2(dbPointer, insert_stmt, -1, &statement, NULL);
if (sqlite3_step(statement) == SQLITE_DONE)
{
labelStatus.text = #"added";
}
else
{
labelStatus.text = #"failed";
}
sqlite3_finalize(statement);
sqlite3_close(dbPointer);
}
}

//your database is not writable because its in the bundle.
NSString *dbPath = [[[NSBundle mainBundle] resourcePath ]stringByAppendingPathComponent:#"KJV.sqlite"];
if you want a readable/writable database, you can do this:
- (void) createEditableCopyOfDatabaseIfNeeded
{
BOOL success;
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *writableDBPath = [documentsDirectory stringByAppendingPathComponent:#"databasename.sqlite"];
NSLog(#"writableDBPath == %#",writableDBPath);
if ([fileManager fileExistsAtPath:writableDBPath])
{
NSLog(#"Database already exist");
}
else
{
NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"databasename.sqlite"];
success = [fileManager copyItemAtPath:defaultDBPath toPath:writableDBPath error:&error];
if (!success)
NSLog(#"Failed to create writable database file with message '%#'.", [error localizedDescription]);
}
}
and heres how you add your data
- (void) addToDatabase
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *databasePath = [documentsDirectory stringByAppendingPathComponent:#"databasename.sqlite"];
if(sqlite3_open([databasePath UTF8String], &mDatabase_update) == SQLITE_OK)
{
NSString *sqlQuery = [NSString stringWithFormat: #"Insert into table
