SQLite 中没有这样的 Table 错误
No Such Table Error in SQLite
这个论坛上已经有一些帖子解决了这个 SQLite 问题。但是，就我所搜索的而言，我没有找到任何令人信服的解决方案。因此，我发布了我面临的类似问题。我相信这个问题不会被标记为重复。
问题来了。
我正在尝试接收有关需要保存在 Android 应用程序的数据库中的新库存的用户数据。在需要保存的6个数据中，5个数据将使用EditText提供，第6个数据将使用Spinner提供。
但是，虽然运行 activity，但我显示的是SQLException: no such table
但是，数据（来自同一应用程序的另一个 activity）正在成功保存到数据库的另一个 table。我确保在添加新的 table 时更新了数据库版本。我还尝试卸载并重新安装该应用程序（我一直只在我的 phone 上测试该应用程序，因为自安装 Android Studio 以来模拟器一直无法运行）。下面提供Logcat资料和Java代码供参考

MainActivity.java中的onClick方法：
public void addInventory(MenuItem item) {
String inventName = addInventory.getText().toString();
String inventCostPrice = costPrice.getText().toString();
String inventSalePrice = salePrice.getText().toString();
String inventVAT = vat.getText().toString();

Message.message(this, "Inserting a Row was unsuccessful");

Message.message(this, "Successfully inserted a Row");
}
//category.setText(""); clears the EditText's existing user fed data
addInventory.setText("");

}else{
Message.message(this, "Please insert/select a valid " +
"\n" +
"\n - Inventory Name " +
"\n - Cost Price " +
"\n - Sale Price " +

}
}
助手Class方法：
public long insertInventory(String inventName, String inventCostPrice, String inventSalePrice, String inventVAT, String inventSaleTax, String inventSupplier) {
SQLiteDatabase db = helper.getWritableDatabase();
ContentValues contentValues = new ContentValues();
contentValues.put(VivzHelper.COLUMN_INVENTORY_NAME, inventName);
contentValues.put(VivzHelper.COLUMN_INVENTORY_COST_PRICE, inventCostPrice);
contentValues.put(VivzHelper.COLUMN_INVENTORY_SALE_PRICE, inventSalePrice);
contentValues.put(VivzHelper.COLUMN_INVENTORY_VAT, inventVAT);
contentValues.put(VivzHelper.COLUMN_INVENTORY_SALES_TAX, inventSaleTax);
contentValues.put(VivzHelper.COLUMN_INVENTORY_SUPPLIER, inventSupplier);
long inventory_id = db.insert(VivzHelper.TABLE_NAME_INVENTORY, null, contentValues);
db.close();
return inventory_id;
}
Table 在助手中创建 Class:
private static final String TABLE_NAME_INVENTORY = "INVENTORYLIST";
private static final String COLUMN_INVENTORY_UID = "inventory_id";
private static final String COLUMN_INVENTORY_NAME = "inventory_name";
private static final String COLUMN_INVENTORY_COST_PRICE = "cost_price";
private static final String COLUMN_INVENTORY_SALE_PRICE = "sale_price";
private static final String COLUMN_INVENTORY_VAT = "vat";
private static final String COLUMN_INVENTORY_SALES_TAX = "sales_tax";
private static final String COLUMN_INVENTORY_SUPPLIER = "supplier";
private static final String CREATE_TABLE_INVENTORY =
"CREATE TABLE " + TABLE_NAME_INVENTORY + "( " + COLUMN_INVENTORY_UID + " INTEGER PRIMARY KEY AUTOINCREMENT," +
" " + COLUMN_INVENTORY_NAME + " VARCHAR(255)," +
" " + COLUMN_INVENTORY_COST_PRICE + " VARCHAR(255)," +
" " + COLUMN_INVENTORY_SALE_PRICE + " VARCHAR(255)" +
" " + COLUMN_INVENTORY_VAT + " VARCHAR(255)" +
" " + COLUMN_INVENTORY_SALES_TAX + " VARCHAR(255)" +
" " + COLUMN_INVENTORY_SUPPLIER + " VARCHAR(255));";
private static final String DROP_TABLE_INVENTORY = "DROP TABLE IF EXISTS" + TABLE_NAME_INVENTORY;
我尝试了很多资源来解决这个问题，但都无济于事。如有任何帮助，我们将不胜感激。
您错过了一些逗号来分隔下一个字段：
"CREATE TABLE " + TABLE_NAME_INVENTORY + "( " + COLUMN_INVENTORY_UID + " INTEGER PRIMARY KEY AUTOINCREMENT," +
" " + COLUMN_INVENTORY_NAME + " VARCHAR(255)," +
" " + COLUMN_INVENTORY_COST_PRICE + " VARCHAR(255)," +
" " + COLUMN_INVENTORY_SALE_PRICE + " VARCHAR(255)" +
" " + COLUMN_INVENTORY_VAT + " VARCHAR(255)" +
" " + COLUMN_INVENTORY_SALES_TAX + " VARCHAR(255)" +
" " + COLUMN_INVENTORY_SUPPLIER + " VARCHAR(255));";
应该是：
"CREATE TABLE " + TABLE_NAME_INVENTORY + "( " + COLUMN_INVENTORY_UID + " INTEGER PRIMARY KEY AUTOINCREMENT," +
" " + COLUMN_INVENTORY_NAME + " VARCHAR(255)," +
" " + COLUMN_INVENTORY_COST_PRICE + " VARCHAR(255)," +
" " + COLUMN_INVENTORY_SALE_PRICE + " VARCHAR(255)," +
" " + COLUMN_INVENTORY_VAT + " VARCHAR(255)," +
" " + COLUMN_INVENTORY_SALES_TAX + " VARCHAR(255)," +
" " + COLUMN_INVENTORY_SUPPLIER + " VARCHAR(255));";
