我不断收到各种形式的错误，例如下面的列，但我在我的代码中看不到任何错误，例如逗号或 ' 在错误的地方等，有没有人知道这里有什么问题，可能很明显。我附上了我认为最相关的部分数据库代码。
android.database.sqlite.SQLiteException：表 MEAL_PLAN 没有名为 plan_recipe 的列（代码 1 SQLITE_ERROR[1]）：，编译时：INSERT INTO MEAL_PLAN（plan_name，plan_recipe）值（'Plan Name'，'14'）
更新
语法都是正确的，但是否与创建/调用它们的顺序有关，这可能导致此问题，我找不到问题所在。请帮忙
