我收到了这个SQLiteException：没有这样的表 我无法在代码中看到任何错误。我已经尝试过清理，卸载应用程序而不是再次重新安装，但它没有用。

异常仅适用于TABLE_NAME3，其他表格正常 所以我完全感到困惑，因为控件进入onCreate方法（我在调试器中检查过）和onCreate（）方法内部我正在为所有表执行Create Table查询。正在创建其他表，仅在TABLE_NAME3上获取异常。
我在上面提到的代码中使用的这三种方法（DatabaseContainerAdapter.java）。
public Cursor showBudget(String[] coloumns, String[] month) {
Cursor cr = null;
SQLiteDatabase db = dc.getWritableDatabase();
try {
Cursor cursor = db.query(DatabaseContainer.TABLE_NAME3, coloumns, DatabaseContainer.MONTH + "=?", month, null, null, null);
cr = cursor;
} catch (SQLException e) {
e.printStackTrace();
}
return cr;
}
public long insertBudget(String budget, int month) {
SQLiteDatabase db = dc.getWritableDatabase();
ContentValues cv = new ContentValues();
cv.put(DatabaseContainer.MONTH, month);
cv.put(DatabaseContainer.BUDGET, budget);
// cv.put(DatabaseContainer.ID, System.currentTimeMillis());
long id = db.insert(DatabaseContainer.TABLE_NAME3, null, cv);
return id;
}
public long updateBudget(String budget, String[] month) {
SQLiteDatabase db = dc.getWritableDatabase();
ContentValues cv = new ContentValues();
cv.put(DatabaseContainer.BUDGET, budget);
long id = db.update(DatabaseContainer.TABLE_NAME3, cv, DatabaseContainer.MONTH + "=?", month);
return id;
}
我尝试过这些东西：
没有什么对我有用。

答案 0 :(得分：2)
我认为您忘记在CREATE_TABLE3查询中添加结束括号。它应该是这样的：
public static final String CREATE_TABLE3 = "CREATE TABLE " + TABLE_NAME3
+ " (" + MONTH + " varchar (20) ,"
+ YEAR + " varchar (20) ," + BUDGET
+ " integer(10)) ;";
答案 1 :(得分：0)
关闭CREATE_TABLE3的大括号。 ＆＃39;）＆＃39;在声明结尾处遗漏
答案 2 :(得分：0)
首先，您扩展SQLiteOpenHelper类并在onCreate()方法中创建表。
请检查以下代码 -
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import java.util.ArrayList;

// TABLE_APP_INFO Columns names
private static final String KEY_APP_ID = "app_id";
private static final String KEY_APP_NAME = "app_name";
private static final String KEY_APP_IMAGE = "app_image";

private static final String KEY_CREATED_AT = "createdAt";

super(context, DATABASE_NAME, null, DATABASE_VERSION);

@Override

db.execSQL(CREATE_APP_INFO);
