如何在swift 2.0中从sqlite数据库中滑动和删除选中的表视图行数据？

var db: OpaquePointer? = nil
let databasePath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first!.appending("/myDatabase.sqlite")

if sqlite3_open(databasePath, &db) == SQLITE_OK {
    print("成功打开数据库")
} else {
    print("无法打开数据库")
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let selectedRow = indexPath.row
    
    // 获取选中行的数据
    let query = "SELECT * FROM tableName WHERE id = \(selectedRow)"
    var statement: OpaquePointer? = nil
    
    if sqlite3_prepare_v2(db, query, -1, &statement, nil) == SQLITE_OK {
        if sqlite3_step(statement) == SQLITE_ROW {
            let column1 = sqlite3_column_text(statement, 0)
            let column2 = sqlite3_column_text(statement, 1)
            
            let data1 = String(cString: column1!)
            let data2 = String(cString: column2!)
            
            // 使用获取到的数据进行滑动和删除操作
            // ...
        }
    }
    
    sqlite3_finalize(statement)
}

// 滑动选中行的数据
let updateQuery = "UPDATE tableName SET column1 = 'newValue' WHERE id = \(selectedRow)"
if sqlite3_exec(db, updateQuery, nil, nil, nil) == SQLITE_OK {
    print("成功滑动数据")
} else {
    print("无法滑动数据")
}

// 删除选中行的数据
let deleteQuery = "DELETE FROM tableName WHERE id = \(selectedRow)"
if sqlite3_exec(db, deleteQuery, nil, nil, nil) == SQLITE_OK {
    print("成功删除数据")
} else {
    print("无法删除数据")
}
