How To Run Sqlite Script
Dec 31, 2010
I don't need to develop an app, how best to do the following, with a script or however is best.
1) Back up a database file /data/data/someapp/databases/database.db
2) Open a database file /data/data/someapp/databases/database.db
3) run some queries
4) close database
That's it - simple. I need to periodically run this script to make some database updates.
I know I can use the sqlite3 shell, but I really don't feel like going through the process everytime of bringing up the shell, opening the database and running the sql file. I want to be able to simply have a script I can click on that will do everything.

I want to create a table whose primary key will be some other field and not _id . The below table gets created but the value of _id remains null :
"create table accounts ("+BaseColumns._ID+" integer , profile_name text primary key" +" name text not null);";
My doubt is wont _id get auto incremented if we do not place "+BaseColumns._ID integer primary key autoincrement+" .

I'm new to Android, I just finished the Notepad Tutorials, where we can create SQLite Databases to save notes. So I wanted to know if it was possible to "import" my own SQLite database (not created with my App but with a 3rd-party software) to my project, and if the answer is yes, where should I save my SQLite databse and how can I have access to it.

I 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):
Code...

I'm doing a application that will use a database with serialized object. The objects will be already serialized and the user will just display things. On a PC I would just make an XML but with android I'm not sure. Can I make an XML and "unpack" it when the user launch the application for the first time or should I do something else?

I 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?

I 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.

Firstly, 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.

I've been using my Activity class to access my DB which made my program freeze sometimes.
So I decided to use AsyncTask instead to handle the DB.
My problem is I don't know how to instantiate my SQLite DB "TheDB" from AsyncTask's class
CODE:.............
This worked fine on the Activity class, but it I dont know how to use it here
TheDB's constructor is TheDB(Context context) but this class is not a "context" so how can i use my DB here?

I am developing a app using android C2DM. sqlite3 is my back-end. Everything is just working fine but am struck with an performance issue regarding sqlite3. so my question is 'can i place the database code somewhere where it will be executed only once i.e The dvm(dalvik vertiual machine) should execute the code pertaining to the db only once; during the successive run the dvm should not go thru the (db)code because the db had been created.
More specifically, my app send msg to all the phones which has my app. so when an app at the client end receives a msg, the dvm should not execute this code : SQLiteDatabase db;
//use tat ref to open or create a table
db = openOrCreateDatabase( "/data/data/de.vogella.android.c2dm.simpleclient/app_database/file__0/0000000000000001.db", SQLiteDatabase.CREATE_IF_NECESSARY, null);
try
{
[code]....
Because everytime a msg comes this code ll be executed.

I am trying to adapt my application from a confirmation model to an undo model. For those of you who don't know, this is where you can delete something with one click but if it was a mistake you can undo it just as easily, as opposed to interrupting the user every time he/she wants to do something to ask the annoying "Are you sure you want to...?" question via dialog.
My app is backed by the Android SQLite DB and I want to be able to undo a limited set of delete and update operations. Also, I only need to be able to undo one sequential change and the information does not have to stick arround for very long.
Everything I read on undo/redo says to use a command model to store the data. My question is how can I store the database changes in a lightweight restorable way?

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.

Is it really necessary to close an SQLite database that your activity has opened (database is in local memory or on SD card)? I would think it would be good practice, but I noticed that the Android samples such as the Notepad tutorial and SearchableDictionary sample do not do this. I've also seen sample code where the database is consistently opened, read from, and closed, but that would seem to add unnecessary overhead.

I have set a content provider, for some reason I am able to to delete a row this way:
getContentResolver().delete(myUri, "_id=" + "3", null);
but i am not able to delete a row that way:
getContentResolver().delete(myUri, "NAME=" + "chris", null);
getting this error:
02-15 15:48:08.197: ERROR/AndroidRuntime(3043): android.database.sqlite.SQLiteException: no such column: chris: , while compiling: DELETE FROM User WHERE NAME=chris
I have checked my database file, and it is there.. but for some reason i can delete columns from my database only by the _id column, how can i fix this?
error:
02-15 15:48:08.197: ERROR/AndroidRuntime(3043): android.database.sqlite.SQLiteException: no such column: idanmoshik1: , while compiling: DELETE FROM User WHERE USER_NAME=idanmoshik1.
