どのようにこれらの問題を解決できますか?Android SQLiteデータベースCREATE TABLEエラー

プロセス:com.example.burhanozen.sqlitedb、PID:4658 android.database.sqlite.SQLiteException: "INTEGER" 周辺:構文エラー(コード1)、コンパイル中:表 students_table(IDを作成INTEGER PRIMARY KEY AUTOINCREMENT、名前テキスト、SURNAME TEXT、MARK INTEGER

com.example.burhanozen.sqlitedb.dbHelper.onCreate(dbHelper.kt:16)-at -at com.example.burhanozen.sqlitedb.dbHelper .insertData(dbHelper.kt:28) -at com.example.burhanozen.sqlitedb.MainActivity $ addData $ 1.onClick(MainActivity.kt:62)

これが主な活動です:

class MainActivity : AppCompatActivity() { 

    internal val helper = dbHelper(this) 


    override fun onCreate(savedInstanceState: Bundle?) { 
     super.onCreate(savedInstanceState) 
     setContentView(R.layout.activity_main) 

    addData() 


    viewAll() 


    } 

    fun viewAll(){ 
     kayitGoster.setOnClickListener{ 
      val res = helper.allData 
      if(res.count == 0){ 
       showMessage("Hata","Veri bulunamadı") 
       [email protected] 
      } 

      val buffer = StringBuffer() 
      while(res.moveToNext()){ 
       buffer.append("Id : " + res.getString(0) + "\n") 
       buffer.append("Name : " + res.getString(1) + "\n") 
       buffer.append("Surname : " + res.getString(2) + "\n") 
       buffer.append("Mark : " + res.getString(3) + "\n") 


      } 




     } 
    } 

    fun showMessage(title:String, message:String){ 
     val builder = AlertDialog.Builder(this) 
     builder.setCancelable(true) 
     builder.setTitle(title) 
     builder.setMessage(message) 
     builder.show() 

    } 



    fun addData(){ 
     gonderButon.setOnClickListener { 
      helper.insertData(
        editisim.text.toString(), 
        soyisim.text.toString(), 
        not.text.toString()) 

     } 

    } 



} 

そして、ここではdbHelper.kt

class dbHelper (context : Context) : SQLiteOpenHelper(context,DATABASE_NAME,null,1) { 


    override fun onCreate(db: SQLiteDatabase) { 
     db.execSQL("CREATE TABLE $TABLE_NAME (ID INTEGER PRIMARY KEY AUTOINCREMENT," + 
       "NAME TEXT," + 
       "SURNAME TEXT," + 
       "MARK INTEGER") 
    } 

    override fun onUpgrade(db:SQLiteDatabase,oldVersion: Int, newVersion: Int){ 
     db.execSQL("DROP TABLE IF EXISTS $TABLE_NAME") 
     onCreate(db) 
    } 

    fun insertData(name:String, surname:String, marks:String){ 
     val db=this.writableDatabase 
     val contentValues = ContentValues() 
     contentValues.put(COL_NAME,name) 
     contentValues.put(COL_SURN,surname) 
     contentValues.put(COL_NOT,marks) 
     db.insert(TABLE_NAME,null,contentValues) 
    } 

    val allData: Cursor 
     get(){ 
      val db=this.writableDatabase 
      val res=db.rawQuery("select * from $TABLE_NAME",null) 
      return res 
     } 


    companion object{ 

     internal val DATABASE_NAME = "students.db" 
     internal val TABLE_NAME = "students_table" 
     internal val COL_ID = "ID" 
     internal val COL_NAME = "NAME" 
     internal val COL_SURN = "SURNAME" 
     internal val COL_NOT = "MARKS" 
    } 
}

使用 'MARK INTEGER' https://sqlite.org/datatype3.html –

であるあなたは、あなたのSQL文で閉じ括弧が欠落しています。あなたが今持っていることは次のとおりです。

Create(db: SQLiteDatabase) { 
    db.execSQL("CREATE TABLE $TABLE_NAME (ID INTEGER PRIMARY KEY AUTOINCREMENT," + 
     "NAME TEXT," + 
     "SURNAME TEXT," + 
     "MARK INTEGER") 

する必要があること:

Create(db: SQLiteDatabase) { 
    db.execSQL("CREATE TABLE $TABLE_NAME (ID INTEGER PRIMARY KEY AUTOINCREMENT," + 
     "NAME TEXT," + 
     "SURNAME TEXT," + 
     "MARK INTEGER)")
