Android :: Android - Inserting - Updating Multiple Records To SQL Database

Jun 24, 2010

I've just started working with SQL and Android and from what I can see, updates and inserts back to the database need to be handled individually?

I can retrieve a Cursor containing multiple records, but if I wanted to apply an update to each record in the cursor, I can only see how to do this individually, using ContentValues and Update(), and then the cursor requires reloading??

Same with if I wish to create multiple new records, these appear to be required to be inserted individually? Can I not create a List and bulk insert?

To me this seems slow and cumbersome, and there has to be something I'm not yet aware of (searching for answers is failing me... likely due to using incorrect terms being new to android/java)

Here's a very simple example of what I basically what I want to achieve, however there must be a better way to achieve this functionality. (I know there are some other bad practises in here, just creating a quick eample)

Android :: Inserting Two More Rows In To Database

Aug 5, 2009

Looks to me like every time you run your app, you insert two more rows in to the database, so the first it will have 2 rows, then 4, 6, 8, etc. On Wed, Aug 5, 2009 at 1:12 PM, saptarshi chatterjee <

Android :: Data Not Inserting In Sqlite Database

Aug 14, 2010

I am an android application developer. I am developing an application which requires of me to use Sqlite database. I have implemented fetching the data, but i am facing problems when i try to insert data into the Sqlite database. The problem that i am having is that the new data i enter is not fetched, i.e nothing is new is being entered into the database.

this is the method i wrote in Data.java
myDataBase is an object of SQLiteDatabase
public void insertTitle(String Recipe)
ContentValues initialValues = new ContentValues();
initialValues.put(COLUMN_NAME,value);
myDataBase.insert(ZRECIPE, null, initialValues);
}
and i create an object "d" of it in Add.java, where i call the "insertTitle()" method. But nothing is inserted.

Android :: Retrieving Records From A Created Database And Put It In Spinner

I created a database with records in it and everything. I am trying to use its fields and put it in a spinner. The database contains university names.

I created a spinner with:

where I am feeding the spinner the records from an array. I want to do it from the database that I created. I read thru the classes and there are 2 ways but I can't find a proper code to use any of them. I just want to insert the code to get records from the database. It shouldn't be complicated is it?

Android :: Limit Records Fetched - Sqlite Database

Apr 22, 2010

I am trying to fetch sms messages from inbox, sent items and drafts. I would like to do a pagination for my list view for that it's imperative that I fetch records in pages/chunks.

I am not familiar with sqlite which is the database I understand android use to store the data. Can someone tell me how can I restrict the number of records I am fetching by using contentResolver.query?

Also what is the way to pull the sqlite database file onto my machine and browse/query it locally to experiment or see data on my machine?

Are there any other better ways to implement pagination in android?

Android :: SQLite - Inserting String With New Lines Into Database From Csv File

Sep 9, 2010

I am trying to inject a long text entry into a SQLite database, in a TEXT field. This text has new lines in it (i.e. it spans multiple paragraphs). I can get the new lines to show up if I do the INSERT manually:

INSERT INTO "LOGENTRY" VALUES(5,40,'PLACE','line1
line2
line4
',1283990533315,'4A','TEXT','',NULL);

but if I have the equivalent text in a CSV file and attempt to .import it into the table, I get an error that it's expecting more columns than exist (as soon as the new line is encountered, the program assumes it's the end of the input and thus it's missing columns). Is this possible? Or is the only way to manually do each INSERT?

Android :: Does Database Get Completely Removed And Recreated Then Updating An App

Aug 28, 2010

I have an app that uses a database. At startup I check to see if my tables are missing and if so I create them. Works great.

I've noticed that if I "adb uninstall" then the next time I run my app the tables are created again (this is what I need), but what about when updating through the marketplace?

I'm in the process of releasing an update, and I've made major changes to the tables. I'd like it if the tables were completely wiped and re-created, in fact my app needs this to happen. If someone updates and has the old tables then there will be a force close. Does anyone know the specifics of this scenario?

My tables are only for lookup, I store no user data so I dont really care about losing data on the updates.
Of course I know an option is to use some type of "version" table and check to see if I need to manually drop and create, but I was wondering if that was even needed.

Android :: Multiple Successive Queries To A Database

Apr 10, 2009

Has anyone other than me needed to make consecutive queries to a sqlitedatabase? My application works sometimes but other times (about 98% of the time), the app will crash. What I'm doing is using the sqlitedatabase.query(..) to return a cursor which I parse, I make multiple successive queries to the database and parse different recordsets/cursors.

My question would be does a sqlitedatabase need to recover or clean up after a .query is issued?

Android :: Android - Accessing Single Database From Multiple Activities In Application

Dec 15, 2009

I have a todo list type application that stores all of the note data in a sqlite3 database. Each activity in the application needs access to the database to edit different parts of the data in real time.

Currently, I have each activity open its own DBManager object (the helper class I created to manage the database). This is causing problems though and I would like a slightly more global access solution so I don't have to keep opening/closing/creating a database.

I'm considering several options, and would like to hear pros and cons of each as well as other suggestions.

Singleton style. Have a wrapper class that returns a reference to the only database manager so any activity that needs it can use it.

Static Manager. Have the manager class be entirely static members and have it open the database on load. Easily accessible by anyone that needs it (which is everyone).

Merger between 1 and 2. I could make a database manager class that initializes the member singleton instance of the database and all of the data manipulation methods were static. Then I wouldn't even need a reference to the singleton to access the database.

Android :: Sharing Sqlite Database Between Multiple Android Activities

Oct 12, 2009

Can two or more Android Activities open an sqlite3 database for write?

I have two Activities that need to insert data into the same sqlite database. When the second Activity calls SQLiteOpenHelper.getWriteableDatabase() an IllegalStateException is thrown with the message "SQLiteDatabase created and never closed".

I've been able to avoid the Exception by making my database object a singleton but I'm thinking there must be a better way.

Android :: Android ContentProvider Database Query Multiple Tables

May 7, 2010

I'm writing an RSS reader for Android. I've faced a certain difficulty which the problem I can't resolve since databases aren't my expertise.. So i figured out maybe one of you could help me out! I currently have 3 tables (Categories, links and feeds). My goal is too link a feed to multiple categories. Therefor I'm using a Link table. My databases is an Android ContentProvider (sqlite) and looks like the following:

| Categories | | Links | | Feeds |
|------------| |---------| |-------|
| _ID | | Category| | _ID |
| Title | | Feed | | Title |
| URL |

I currently wrote the following code in my FeedListActivity to retrieve a list of links and their feeds.

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

Now my question:

I was wondering how I could optimize this database layout, code or query so I would get my entries in a more efficient way. Because i believe this link table or the query to retrieve links isn't needed! Or am i doing this the correct way?

Android :: Android - Use One SQLiteOpenHelper Class For Multiple Database Files

Nov 20, 2010

My app uses two databases (separate files). To handle these databases I have created two Helper classes which extend SQLiteOpenHelper, one for each database.

I am now going to add a third database and wonder whether I need to create yet another Helper class (and if I used a 4th and a 5th database would I need even more Helper classes), or can I use the same Helper class for multiple databases?

The problem that I see with trying to use just one Helper class is that I can't see how to pass the name of the individual database files to the Helper. At present the name of the database is hard-coded as a Static field of each of the Helper classes, but if I had only one Helper class I would need to be able to pass the different names in to the Constructor when creating the separate Helper objects; the problem is that the SQLiteOpenHelper Constructor seems to be called by Android with just one parameter: the Context.

Android :: Multiple-choice List From The Sqlite Database In Android

Jan 23, 2010

I'm new to Android programming, and I wanted to pull list options from a column of the SQLite database for the user to select. How would I go about doing this? Like, say the database table to be read is called countries, and the columns were ID, country, and capital. How would I let the user pick from the list of capitals and have the application return the information in that row?

Android :: Inserting Data Into Cursor?

Jun 23, 2009

I'm looking for a way to insert data into a cursor that is separate from the SQL database it retrieves the rest of the information from. Is there any way to to this, or is there a different way to add more information to a list view item? What I'm trying to do is to use a date column for each entry in the list to calculate the number of days until that date (and then put that number in the list item). I know how to get the value, but I just cant find a way to put it into the list without it being in the cursor.

My problem lies already in the first three lines. The contact does not seem to be stored. However, consecutive runs of this show, that the internal ID is increased nonetheless.

Is there something I am missing? Do you have to "commit" the changes?
