这是我的代码。

public class DatabaseHelper extends SQLiteOpenHelper {
public static final String DATABASE_NAME ="student.db";
public static final String TABLE_NAME ="student.table";
public static final String COL_1="ID";
public static final String COL_2="NAME";
public static final String COL_3="SURNAME";
public static final String COL_4="MARKS";
public DatabaseHelper(Context context){
    super(context,DATABASE_NAME,null,1);

}

@Override
public void onCreate(SQLiteDatabase db) {

    db.execSQL("Create Table " + TABLE_NAME + "(ID INTEGER PRIMARY KEY AUTOINCREMENT, NAME TEXT, SURNAME TEXT, MARKS TEXT);");

}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    db.execSQL("DROP TABLE IF EXIST"+TABLE_NAME);
    onCreate(db);
}
public boolean insertData(String name,String surname,String marks){
    SQLiteDatabase db=this.getWritableDatabase();
    ContentValues contentValues=new ContentValues();
    contentValues.put(COL_2,name);
    contentValues.put(COL_3,surname);
    contentValues.put(COL_4,marks);
    long result=db.insert(TABLE_NAME,null,contentValues);
    if(result==-1)
        return false;
    else
        return true;
}
    }

有人能帮助我吗？

使用此行创建表： -

 db.execSQL("CREATE TABLE " + TABLE_NAME + "("
                + COL_1+ " INTEGER," + COL_2 + " TEXT," + COL_3+ " TEXT," + COL_4 + " TEXT" + ")";);

请注意编写代码。因为错误的语法会产生错误。所以请编写与我写的相同的代码。

DATA NOT INSERT，导致近表语法错误
