  • 0

I’m trying to insert values using ContentValues, I’ve inserted 5 values to 5 columns After I run the application, I’ve only the row with last set of values of ContentValues. The first four set is not inserted.

      ContentValues cv = new ContentValues();
       cv.put("name", "Cs Tech");
       cv.put("name", "Wipro");
       cv.put("name", "TCS");
       cv.put("name", "Infosys");
       cv.put("name", "Cognizant");

       cv.put("mail", "joe@info.com");
       cv.put("mail", "bru@wipro.com");
       cv.put("mail", "jen@tcs.com");
       cv.put("mail", "ram@infosys.com");
       cv.put("mail", "cts@cts.com");

       cv.put("contact", "180 151 2010");
       cv.put("contact", "180 151 2011");
       cv.put("contact", "180 151 2012");
       cv.put("contact", "180 151 2013");
       cv.put("contact", "180 151 2014");

       cv.put("date", "27 Jul 2011");   
       cv.put("date", "27 Jul 2011");
       cv.put("date", "27 Jul 2011");
       cv.put("date", "27 Jul 2011");
       cv.put("date", "27 Jul 2011");

       this.db.insert(TABLE_NAME, "name", cv);

    It is not hard to understand that ContentValues is some kind of a hashtable which implies that this peice of code

        cv.put("name", "Cs Tech");
    cv.put("name", "Wipro");
    cv.put("name", "TCS");
    cv.put("name", "Infosys");
    cv.put("name", "Cognizant");

    is ultimately overwriting the Value with key=”name” 4 times and name is finally getting the last value!

    For this to work, you should do it sequentially like this:

    ContentValues cv = new ContentValues();
       cv.put("name", "Cs Tech");
       cv.put("mail", "joe@info.com");         
       cv.put("contact", "180 151 2010");
       cv.put("date", "27 Jul 2011");

       this.db.insert(TABLE_NAME, "name", cv);

       cv.put("name", "Wipro");
       cv.put("mail", "bru@wipro.com");
       cv.put("contact", "180 151 2011");
       cv.put("date", "27 Jul 2011");

       this.db.insert(TABLE_NAME, "name", cv);

       cv.put("name", "TCS");
       cv.put("mail", "jen@tcs.com");  
       cv.put("contact", "180 151 2012");
       cv.put("date", "27 Jul 2011");

       this.db.insert(TABLE_NAME, "name", cv);

       cv.put("name", "Infosys");
       cv.put("mail", "ram@infosys.com");
       cv.put("contact", "180 151 2013");
       cv.put("date", "27 Jul 2011");

       this.db.insert(TABLE_NAME, "name", cv);

       cv.put("name", "Cognizant");
       cv.put("mail", "cts@cts.com");
       cv.put("contact", "180 151 2014");
       cv.put("date", "27 Jul 2011");

       this.db.insert(TABLE_NAME, "name", cv);
