Question

I am trying to update cached_name column of callog.calls table in android,but getting sql lite exception .I have been trying this for long but could not able to come up with anything.I have searched a lot but could not find sufficient information about update statement.kindly help.

ContentResolver cr = getContentResolver(); 

            Cursor cur = cr.query(CallLog.Calls.CONTENT_URI,
                null, null, null, null);
ContentValues value=new ContentValues();
value.put("CallLog.Calls.CACHED_NAME","frank");
  cr.update(CallLog.Calls.CONTENT_URI,value,CallLog.Calls.CACHED_NAME, null);

Error:

The syntax of your call to update is wrong. It needs to look like this:

cr.update(CallLog.Calls.CONTENT_URI,value,null, null);

that will update all the values in the table. To update a specific row do:

cr.update(CallLog.Calls.CONTENT_URI,value,CallLog.Calls.CACHED_NAME +" = ?", new String[]{oldName});

where oldName is the value to use in your WHERE clause.
