Bagaimana cara memasukkan beberapa data ke dalam database Sqlite 3

Melalui kode berikut saya mengambil data dari Db, namun saya perlu memasukkan beberapa data ke dalam database Sqlite3 dengan kode ini sebelum pernyataan pilih. Adakah yang bisa memberi tahu saya di mana saya harus meletakkan kueri penyisipan dan bagaimana cara menjalankannya.

Saya memilih data melalui kode berikut:

sqlite3* database;

- (void)initializeDatabase 
{   
    list=[[NSMutableArray alloc] init];
    BOOL success;
    NSFileManager *filemanager=[NSFileManager defaultManager];
    NSError *error;
    NSArray *paths=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory= [paths objectAtIndex:0];
    NSString *writablePath=[documentsDirectory stringByAppendingPathComponent:@"SymbolTalk.sqlite"];
    success=[filemanager fileExistsAtPath:writablePath];
    if(!success)
    {
        NSString *defaultDBPath=[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"SymbolTalk.sqlite"];
        success=[filemanager copyItemAtPath:defaultDBPath toPath:writablePath error:&error];
        if(!success)
        {
            NSAssert1(0,@"Failed to create writable databasefile withw message %@.",[error localizedDescription]);
        }
    }

    //Specify where to get the database from
    NSArray *paths=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory= [paths objectAtIndex:0];
    NSString *path=[documentsDirectory stringByAppendingPathComponent:@"SymbolTalk.sqlite"];

    //Open the database
    //might have to make database as property
    if(sqlite3_open([path UTF8String], &dataBase) ==SQLITE_OK)
    {
        const char *sql="select filename from scenes";
        sqlite3_stmt *statement;

        if(sqlite3_prepare(dataBase, sql, -1, &statement, NULL) == SQLITE_OK)
        {
            while (sqlite3_step(statement) == SQLITE_ROW) 
            {
                //NSLog(@"%@",[NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 0)]);
                [list addObject:[NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 0)]];
            }
        }
    }
}
