View 4 Replies View RelatedAndroid :: Delete Top Row In SQlITE Database
Aug 2, 2010
public void delete(String id, String name, String phonenumber, String time, String message)
{
String[] args={id};
getWritableDatabase().delete("texts", "_ID=?", args);
}
It works fine, and deletes the specified row. However, I also want to implement it so that I can delete the most recent (earliest date) entry in the database, which should be at the top of the table. I know I can do this by altering the last 2 parameters of delete, but I cannot figure out what to change them to.
Android :: Why SQLite Can't Delete Columns?
Feb 15, 2010I have set a content provider, for some reason I am able to to delete a row this way:

Jul 23, 2010Last night I donated and am just waiting for the paid version now, but I have a couple of questions:
1. What exactly is "freezing" an app? Will it remove the app from the app drawer? Will it just prevent it from running?
2. Can I use Titanium backup to delete apps that are safe for delete like amazon.mp3, etc?
3. If I "freeze" an app like backup assistant will it still be on the phone so that it doesn't brick if I do a reset?
4. Can I delete or freeze things like crap ringtones so they don't show up when I am setting a ringtone?

Apr 1, 2009I read in the documentation for SQLite that there should be some core functions and aggregate functions available, but I can't seem to use them in my code.. Can anyone help? Here's the documentation ad: http://www.sqlite.org/lang_aggfunc.html http://www.sqlite.org/lang_corefunc.html There is for example the function count() but how do I use it? I have tried to use it as stated below, but none of the functions in the documentation is available that way (i.e when I type "db." the list that shows in Eclipse documentation doesn't include any of the functions from the SQLite doc except from execSQL):

Android :: Database - XML Or SQLite?

View 3 Replies View RelatedAndroid :: Use Own Sqlite Database?
Mar 5, 2010I put my database field in "assets" folder. And use the code from this blog to copy the database to "/data/data/my_packname/databases/", (This copy code i run it in the onCreate() method when i run this app) then use select * from ... to get data. But it gives me the exception: no such table. Someone told me that if i am attempting to copy the file in SQLiteOpenHelper's onCreate(), it's too late. So the copy file code can not copy the complete file. So i need to use adb or ddms to pull the database first? So, Anyone can teach me how to use my own databse?
View 3 Replies View RelatedAndroid :: SQLite Using The SQLiteOpenHelper
Jun 9, 2010I have a SQLite database, and several tables within that datbase. I am developing a DBAdapter for each table within the database. (reference Reto Meier's Professional Android 2 Application Development, Listing 7.1).
I am using the adb shell to interface with the database from the command line and see that the database is being populated as I expect. Occasionally, I want to drop a table so that I can ensure it's being built properly, from scratch.
The problem is that SQLiteOpenHelper only checks to see if the database exists. Is there a typical solution to writing a helper to also see that the table(s) exists? Basically once I drop a table, the helper checks to see that the database exists and assumes all is well.
Also, the CREATE_DATABASE string used in the reference above only creates the one table. Should I consider using the DBAdapter for an adapter to ALL of my tables? That doesn't seem as clean to me.
Android :: SQLite And ListViews?
Nov 18, 2009Firstly, I have found many examples of how to grab data from a db and place it into a list, however this seems to be all for ListActivites.
My list is part of the UI and therefore I can't use a ListActivity because it does not consume the whole screen (or can I?).
This is the UI:
CODE:........
So, from what ive read I need to grab the data from the db, then place it into some sort of array then use an array adapter to fill the list view. Is that correct? If so, is there some sample code because all I can find is code releated to ListActivites.
