Question

Have a database with table name status and column name is column1. I need to update this.

I have a String value in Activity1 <

Answer 1

Follow this code,it return no. of rows effected while updating.

SQLiteHelper helper;
public int updateName(String oldName,String newName)
{
SQLiteDatabase db = helper.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(this.NAME, newName);
String [] whereArgs={oldName};

int count = db.update(helper.TABLE_NAME, values, helper.NAME+" =? ",whereArgs);
 return count;
 }

where helper is an object of class that extends SQLiteOpenHelper like the code below..

static class SQLiteHelper extends SQLiteOpenHelper
{
 ....////
 private static final String DATABASE_NAME = "databaseName";
 private static final String TABLE_NAME = "TABLENAME";
 private static final int DATABASE_VERSION = 1;
 private static final String UID = "_id";
 private static final String NAME = "Name";
 private static final String PASSWORD = "Password";
 private static final String CREATE_TABLE ="CREATE TABLE "+ TABLE_NAME +"(" + UID + " INTEGER PRIMARY KEY AUTOINCREMENT," + NAME + " VARCHAR(255)," + PASSWORD + " VARCHAR(255));";

 public SQLiteHelper(Context context) 
 {
    super(context, DATABASE_NAME, null, DATABASE_VERSION);
    this.context = context;
    Message.Message(context, "Constructor Called");


}

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


    try {
        Message.Message(context, "OnCreate Called");
        db.execSQL(CREATE_TABLE);
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        Message.Message(context, "" + e);
    }

}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    // TODO Auto-generated method stub

    try {
        Message.Message(context, "onUpgrade Called");
        db.execSQL(DROP_TABLE);
        onCreate(db);
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        Message.Message(context, ""+e);
    }

}
      }
