android.database.sqlite.SQLiteException : near ": syntax error (code 1): , 编译时:android 编程错误

Question

我创建了一个包含两个表的 android 数据库。第二个尚未初始化，但对于第一个我收到此错误。

这是我的日志。

这是我的 dbhelper。

public class DBHelper extends SQLiteOpenHelper {

        db.execSQL("DROP TABLE IF EXISTS " + TABLE_EXPENSE);
        onCreate(db);
    }
}

这是我的 sqlcontroller。

public class SQLController {

    private DBHelper dbhelper;
    private Context ourcontext;
    private SQLiteDatabase database;

    public SQLController(Context c) {
        ourcontext = c;

    }

    //Getting Cursor to read data from table

        }
        return c;
    }

    //Getting Cursor to read data from table
    public Cursor readExpenseData() {
        String[] allColumns = new String[] { DBHelper.EXPENSE_ID,
                DBHelper.EXPENSE_AMOUNT, DBHelper.EXPENSE_PAYEE, DBHelper.EXPENSE_DATE,
                DBHelper.EXPENSE_CATEGORY, DBHelper.EXPENSE_PAYMENTS };
        Cursor c = database.query(DBHelper.TABLE_EXPENSE, allColumns, null,

    //Updating record data into table by id

        ContentValues cvUpdate = new ContentValues();
        cvUpdate.put(DBHelper.INCOME_AMOUNT, newIncomeAmount);
        cvUpdate.put(DBHelper.INCOME_PAYER, newIncomePayer);

        return i;
    }

    public int updateExpenseData(long expenseID, String newExpenseAmount, String newExpensePayer, String newExpenseDate,
                                String newExpenseCategory, String newExpensePayments) {

        database.delete(DBHelper.TABLE_EXPENSE, DBHelper.EXPENSE_ID + "="
                + expenseID, null);
    }
}

这是我的主要 Activity 。

public class MainActivity extends ActionBarActivity {

    ListView lv;
    SQLController dbcon;
    TextView incomeID_tv, incomePayer_tv, incomeAmount_tv;
    TextView incomeDate_tv, incomeCategory_tv, incomePayments_tv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        dbcon = new SQLController(this);
        dbcon.open();
        lv = (ListView) findViewById(R.id.incomeList_id);

        Cursor cursor = dbcon.readIncomeData();
        String[] from = new String[] { DBHelper.INCOME_ID, DBHelper.INCOME_AMOUNT, DBHelper.INCOME_PAYER,
                DBHelper.INCOME_DATE, DBHelper.INCOME_CATEGORY, DBHelper.INCOME_PAYMENTS};
        int[] to = new int[] { R.id.income_id, R.id.income_amount, R.id.income_payer, R.id.income_date,
                R.id.income_category, R.id.income_payments};

        SimpleCursorAdapter adapter = new SimpleCursorAdapter(
                MainActivity.this, R.layout.income_entry, cursor, from, to);

        adapter.notifyDataSetChanged();
        lv.setAdapter(adapter);

        lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                                    int position, long id) {
                incomeID_tv = (TextView) view.findViewById(R.id.income_id);
                incomeAmount_tv = (TextView) view.findViewById(R.id.income_amount);
                incomePayer_tv = (TextView) view.findViewById(R.id.income_payer);
                incomeDate_tv = (TextView) view.findViewById(R.id.income_date);
                incomeCategory_tv = (TextView) view.findViewById(R.id.income_category);
                incomePayments_tv = (TextView) view.findViewById(R.id.income_payments);

                String incomeID = incomeID_tv.getText().toString();
                String incomeAmount = incomeAmount_tv.getText().toString();
                String incomePayer = incomePayer_tv.getText().toString();
                String incomeDate = incomeDate_tv.getText().toString();
                String incomeCategory = incomeCategory_tv.getText().toString();
                String incomePayments = incomePayments_tv.getText().toString();

                Intent modify_intent = new Intent(getApplicationContext(),
                        IncomeEdit.class);
                modify_intent.putExtra("incomeID", incomeID);
                modify_intent.putExtra("newIncomeAmount", incomeAmount);
                modify_intent.putExtra("newIncomePayer", incomePayer);
                modify_intent.putExtra("newIncomeDate", incomeDate);
                modify_intent.putExtra("newIncomeCategory", incomeCategory);
                modify_intent.putExtra("newIncomePayments", incomePayments);
                startActivity(modify_intent);
            }
        });
    }

DBHelper 的第 55 行是这样的:

db.execSQL(CREATE_INCOME_TABLE);

SQLController 的第 21 行是这样的:

database = dbhelper.getWritableDatabase();

MainActivity 的第 29 行是这样的:

dbcon.open();

我在其他问题中看到它可能来自表名。它们之间有空格，但在我更改它之后，它仍然无法正常工作。

Answer 1

你正在执行命令:

create_income_table income(
    _id INTEGER PRIMARY KEY AUTOINCREMENT,
    income_amount TEXT NOT NULL,
    income_payer TEXT NOT NULL,
    income_date TEXT NOT NULL,
    income_category TEXT NOT NULL,
    income_payments TEXT NOT NULL
);

将 create_income_table 替换为 CREATE TABLE。您需要执行此 SQL:

CREATE TABLE income(
    _id INTEGER PRIMARY KEY AUTOINCREMENT,
    income_amount TEXT NOT NULL,
    income_payer TEXT NOT NULL,
    income_date TEXT NOT NULL,
    income_category TEXT NOT NULL,
    income_payments TEXT NOT NULL
);
