ошибка поиска запроса андроида sqlite

Question

Я застрял в этом за последние пару часов (к сожалению).

Я создаю приложение с SQLite, где приложение может выполнять все гибкие команды SQL. Я в настоящее время зациклился на том, как искать запрос из столбцов, отличных от ID.

SQLiteDb:

public class SqliteDbTab extends SQLiteOpenHelper 
    { 
public static String DATABASENAME = "androidadvancesqlite"; 
public static String TABTABLE = "TABTABLE"; 

public static String ID = "ID"; 
public static String NAME = "name"; 
public static String PHONE = "PhOnE"; 
public static String MAIL = "mail"; 
public static String ADDRESS = "address"; 
public static String IMAGE = "image"; 

private ArrayList<Helperdb> cartList = new ArrayList<Helperdb>(); 
Context c; 

public SqliteDbTab(Context context) 
{ 
    super(context, DATABASENAME, null, 33); 
    c = context; 
} 

@Override 
public void onCreate(SQLiteDatabase db) 
{ 
    // TODO Auto-generated method stub 

    db.execSQL("CREATE TABLE if not exists TABTABLE(ID INTEGER PRIMARY KEY AUTOINCREMENT," 
      + NAME+ " text, " 
      + IMAGE + " BLOB , " 
      + PHONE + " text , " 
      + MAIL + " text , " 
      + ADDRESS + " TEXT)"); 
} 
@Override 
public void onUpgrade(SQLiteDatabase db, int arg1, int arg2) 
{ 
    // TODO Auto-generated method stub 
    db.execSQL("DROP TABLE IF EXISTS" + TABTABLE); 
    onCreate(db); 
} 

public void addContact(Helperdb productitem) 
{ 
    SQLiteDatabase db = this.getWritableDatabase(); 
    ContentValues contentValues = new ContentValues(); 
    contentValues.put("NAME", productitem.name); 
    contentValues.put("PHONE", productitem.phone); 
    contentValues.put("MAIL", productitem.mail); 
    contentValues.put("ADDRESS", productitem.address); 
    contentValues.put("IMAGE", productitem.image); 
    db.insert(TABTABLE, null, contentValues); 
    db.close(); 
} 

// update 
public void updateContact(Helperdb productList) 
{ 
    SQLiteDatabase db = this.getWritableDatabase(); 
    ContentValues contentValues = new ContentValues(); 
    contentValues.put("NAME", productList.name); 
    contentValues.put("PHONE", productList.phone); 
    contentValues.put("MAIL", productList.mail); 
    contentValues.put("ADDRESS", productList.address); 
    contentValues.put("IMAGE", productList.image); 
    db.update(TABTABLE, contentValues, "ID="+ productList.id, null); 
    db.close(); 
} 

public void emptyProduct() 
{ 
    try { 
     SQLiteDatabase db = this.getWritableDatabase(); 
     db.execSQL(TABTABLE); 
     db.close(); 
     } catch (Exception e) 
     { 
      e.printStackTrace(); 
     } 
} 

public void removeProduct(String id,String name, String phone, String mail,String address,byte[] blob) 
{ 
    try { 
     String[] args = { id }; 
     getWritableDatabase().delete(TABTABLE, "ID=?", args); 
    } catch (Exception e) 
    { 
     e.printStackTrace(); 
    } 
} 

public ArrayList<Helperdb> getProudcts() 
{ 
    cartList.clear(); 
    SQLiteDatabase db = this.getWritableDatabase(); 
    Cursor cursor = db.rawQuery("select * from TABTABLE", null); 
    if (cursor.getCount() != 0) 
    { 
     if (cursor.moveToFirst()) 
     { 
      do 
      { 
       Helperdb item = new Helperdb(); 
       item.id = cursor.getString(cursor.getColumnIndex("ID")); 
       item.name = cursor.getString(cursor.getColumnIndex("name"));      
       item.phone = cursor.getString(cursor.getColumnIndex("PhOnE")); 
       item.mail = cursor.getString(cursor.getColumnIndex("mail"));      
       item.address = cursor.getString(cursor.getColumnIndex("address"));     
       item.image = cursor.getBlob(cursor.getColumnIndex("image")); 

       cartList.add(item); 
      } 
      while (cursor.moveToNext()); 
     } 
    } 
    cursor.close(); 
    db.close(); 
    return cartList; 

} 

public ArrayList<Helperdb> getProudcts(String record) 
{ 
    cartList.clear(); 
    SQLiteDatabase db = this.getWritableDatabase(); 
    Cursor cursor=db.query(true,TABTABLE,new String[]{"ID","name","PhOnE","mail","address","image"},"name"+"=?",new String[]{record},null,null,null,null); 
    if (cursor.getCount() != 0) 
    { 
     if (cursor.moveToFirst()) 
     { 
      do { 
       Helperdb item = new Helperdb(); 
       item.id = cursor.getString(cursor.getColumnIndex("ID"));

     } 
    } 
    cursor.close(); 
    db.close(); 
    return cartList; 
}

Answer 1

Я думаю, вы должны попробовать "имя" + "= ' "+ запись +" %'" вы можете попробовать запрос, как этот

String SEARCH_QUERY = "SELECT * FROM TABTABLE WHERE name like '"+record+"%'"; 

Cursor cursor = db.rawQuery(SEARCH_QUERY, null); 
cursor.moveToFirst(); 
if (cursor.getCount() > 0) 
{ 
    do { 
       Helperdb item = new Helperdb(); 
       item.id = cursor.getString(cursor.getColumnIndex("ID")); 
       item.name = cursor.getString(cursor.getColumnIndex("name")); 
       item.phone = cursor.getString(cursor.getColumnIndex("PhOnE")); 
       item.mail = cursor.getString(cursor.getColumnIndex("mail"));      
       item.address = cursor.getString(cursor.getColumnIndex("address"));     
       item.image = cursor.getBlob(cursor.getColumnIndex("image")); 
       cartList.add(item); 
    } while (cursor.moveToNext()); 
} 
cursor.close();
