Android :: Only First Table In Create Table Statement Being Created

May 28, 2010

The table "credentials" does show up in the adb shell.

I've checked logcat and it doesn't seem to report a problem...

CODE:........

I've been pouring over this and I bet its some silly syntax typo! Or, at least I hope it is something trivial.

Android :: Sqlite Exception No Such Table?

Nov 13, 2010

I have decided that I hate SQL and for that purpose I am trying to make a helper class that I can reuse over and over and never have to mess with it again but it isnt working!

Here is what i have right now:

CODE:.........

I have included several System.out.println() statements to help me debug the code and find problems so please ignore them. PrintDB is another test that I wrote that I am using to make sure everything is working. Now this is what I have written to make sure everything is working....

CODE:.....................

Running this code everything goes great and all the System.out.println() statements have the right information in them until it gets to the databaseView.setText(db.printTable(tableName));
part and it throws an exception

CODE:................

This has me so confused because that same line of code is used in the getColNames() method that was called several times before this and ran with no problem. Also if the table didn't exist wouldn't it have thrown an exception when I called insertRow()? I called that method 5 times in a row with not a single exception thrown! What is happening here?

Implement onCreate() in your DBOpenHelper. Put there content of the createTable() method.

Why would it be necessary to create the table in the onCreate() method? If I were to do this would I be able to use my existing method to do so and just call it from this method?

And the second why you don't use content providers and uri >concept which is already SQLless?

Android :: Game - Duplicating Entire Table (SQLite)

Apr 6, 2010

In my game I am handling the loss of a character (represented programmatically with their own table) - however there are 4 such tables. I would like to know if there is a simple way to simply tell SQLite to make character 2's entire table equal character 3's? Just trying to not leave a gap in the lineup.

I was considering pulling all the data, sorting it out, putting it into the table and then deleting - I just wanted to know if there was a nifty shortcut to tell SQLite that I wanted to duplicate an entire table at another preexisting table?

Android :: Detect If A Table Contains A Column In Droid / Sqlite

Apr 20, 2010

So I have an app on the market, and with an update I want to add some columns to the database. No problems so far. But I want to detect if the database in use is missing these columns, and add them if this is the case. I need this to be done dynamically and not just after the update to the new version, because the application is supposed to still be able to import older databases. Normally I would be able to use the PRAGMA query, but Im not sure how to do this with Android. I cant use execSQL since it is a query, and I cant figure out how to use PRAGMA with the query()-function.

Ofcourse I could just catch exceptions and then add the column, or always add the columns to each table before I start to work with it, but that is not a neat solution.

Android :: Copy Row Data From One Table To Another In SQLite Droid?

Oct 11, 2010

How do i efficiently copy a row data from one table to another table, where both of them are the same structure. i could go the much harder way of retrieving initial values from the row in the first table and then inserting to the second table. But i feel there is a more efficient way this can be done.

Android : SQLite Cursor Out Of Bounds Exception On SELECT Count FROM Table

Jun 22, 2010

The following function is giving me an out of bounds exception...

public void count(){
SQLiteDatabase db = table.getWritableDatabase();
String count = "SELECT count(*) FROM table";
Cursor mcursor = db.rawQuery(count, null);
int icount = mcursor.getInt(0);
System.out.println("NUMBER IN DB: " + icount);}

It's meant to return the number of rows in the database. Anybody know whats wrong? am I perhaps doing this task the wrong way?

Android :: Insert Data On Sqlite Database Table From Word Or Excel Document?

May 22, 2010

In my project, I would like to create a database with single table. I would also like to insert data on this table from word or excel document. is it possible? if so please how can I do it? some code snippets would be of great help. I have four different activities which I would like them to interact with this single table. the first is the main activity and its purpose is just to launch the other three activities according to user choice. so it has no interaction with the DB. but the other three activities will read from the table whenever called. Can you please tell me how to call the dbhelper on these activities? I am unable to do this and I am currently creating one db per each activity which is not the optimal way.

Sqlite Query - Record Is Being Returned If Table Is Empty?

Mar 21, 2012

I've a problem with a query in sqlite3.

The query is very simple:

SELECT MAX (INIT_DATE) INIT_DATE FROM TABLE;

When my application execute this query, and the table is empty, a record is returned. I can't understand why a record is being returned if the table is empty. It should return cero results.

I've tried to execute the query in two different ways:

cursor = db.query(true, "TABLE", new String[] {"MAX(INIT_DATE) AS INIT_DATE"}, null, null, null, null, null, null);

cursor = db.rawQuery("SELECT MAX(INIT_DATE) AS INIT_DATE FROM TABLE", null);

Android :: How To Create A Sqlite Dist Db Function

Feb 28, 2010

We are building an Android App that will use user's current location (lat, long) and show top 50 venues around the current location, sorted by distance.We have these venues stored in an SQLite DB. We plan to ship with the sqlite DB with the app.In order to fetch only the relevant top 50 closest venues, we want to define a db function DIST (to calculate distance between two points) and use it in our query.How can I define a custom SQLite function for Android Apps? What will be the Java API call to do this?We have successfully implemented this approach in our iPhone App - using Objective C.

Android :: How To Use SQLite Database? (Create / Open)

Apr 18, 2010

I am trying to use

SQLiteDatabase.openDatabase( "/data/data/edwin11.myapp/databases/myapp.db", null, (SQLiteDatabase.CREATE_IF_NECESSARY | SQLiteDatabase.NO_LOCALIZED_COLLATORS));

To create/open a database instead of making use of the SQLiteOpenHelper (because I want to pass in the flag SQLiteDatabase.NO_LOCALIZED_COLLATORS. However, I am getting this exception for that line of code:

04-18 09:50:03.585: ERROR/Database(3471): sqlite3_open_v2("/data/data/edwin11.myapp/databases/myapp.db", &handle, 6, NULL) failed

04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at android.database.sqlite.SQLiteDatabase.openDatabase(SQLiteDatabase.java:638)...

Doing some testing just before that line of code (using File.isExists) shows that the file /data/data/edwin11.myapp/databases/myapp.db does not exist. Would that be the cause of the error? (Or am I just using SQLiteDatabase.openDatabase the wrong way?) Would it help if I create the file beforehand? (Shouldn't that be taken care of by the SQLiteDatabase.CREATE_IF_NECESSARY flag that I passed in?) If creating the file manually is the way to go, is it just an empty file, or do I have to write something to it?

Android : Create A Sqlite Database That I Can Manually Input Data From My Computer

Nov 30, 2009

I have certain needs that I am having trouble making an app for. I was hoping to be able to create a sqlite database that I can manually input data from my computer and search the data on my droid. I wanted to set up tags or full data search within each sqlite database object so and pull up a listing of best matches for the given search term.

The use for it is that I work on an Air Force Base and my job is very broad. I wanted to custom build an app that I could list all of the information pertaining to my job and be able to search it as I work to find solutions to problems way quicker than we are doing it now.

Is there any such app. I've been trying to create my own and it looks like it would be a mix between notepad and searchable dictionary but not quite.
