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 <

I am trying to insert rows into my database, but nothing gets persisted. Here is my helper class:
package com.android.cancertrials;
import java.util.Calendar;
import java.util.GregorianCalendar;
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;

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.
I am new to android development.currently i am facing a problem while inserting/retrieving image to sqlite database using android Code...
View 1 Replies View RelatedI 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?
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)

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?

View 3 Replies View RelatedIve developed a DB for use with my app but I've realised that I actually want extend my db to incorporate images! I will be hosting the db online but for now I am using it locally for development purposes. To create my db I have been using SQLiteBrowser, which I think is a standalone version of the Firefox SQLiteManager plugin, however I cant see a way to insert an image. I recognise that an image will have to be transfered into a byte array and stored as a blob, but rather that developing this element of the db programatically, I was wondering if the was a gui tool to help me skip this developmental element.
View 1 Replies View RelatedI'm working on a simple Android app, it is much like any other simple Database app. I have 4 EditText fields where the user inputs 4 different small pieces of text. I want this text to be inserted in to my Database table in the corrects rows for my columns. I am not really sure how to go about doing this. I know onClickListener needs to be used but not sure how to use it.
View 3 Replies View RelatedHow do I use an SQL statement on an sqllite database to insert the current date in UTC. I found the NOW function but what format is that in? This will be on mobile devices so everyone will have a different locale, however, I need a standard time format because the device will compare the dates with my server. Also, is there a way to automatically update a 'modified' field when the data in the row is changed like you can in MySQL?
View 2 Replies View RelatedI need to insert approximately one million rows of data (spread over 4 tables) - each row has one or two numeric fields, and two or three text fields (normally quite short). Single-column indexes on all the fields. After doing some tests on the emulator with a small test set, I extrapolated (assuming the last row will be inserted with a similar speed to the first row) my results to figure out that this would take about 15 hours (I have a Core 2 Duo running Vista). However, then I tried running the small test set on my Hero and I was surprised to see it run more than four times faster. I would guess it would take about 3 hours on the Hero. Alternatively, I could make the pre-populated database available as a download on the first run but this is likely to be a 120MB download. I have a few questions I'm hoping someone can help me with: 1. SQLite performance on the actual device being 4-5 times faster compared to the emulator - is this normal/expected? 2. Do the figures above generally sound fast/slow/normal (sorry this is so vague)? 3. From a user perspective - would it be best to provide a 120MB download or a 3 hour "first-time initialisation" step (plus 6MB download)?

How do you do that? - i.e. insert the status-bar within ones own 'full- screen' View?

View 2 Replies View RelatedWhen I insert the USB cable, I can go to notifications and mount the SD card so I can transfer files to and from my PC. This all works fine. Lets say I am all done with the connection to my PC so I want to disconnect the USB cable. I go to notifications and select "turn off USB storage". I get the message that I need to "unmount the host". So I go to settings and unmount the SD card, go back to notifications and turn off usb storage. Done, all this works fine too. Later in the day, I want to browse some videos and picture that are located on my SD card. I get the message "SD card unmounted". No problem, I will just go to setting and mount it? However, not mount option exists in settings. The only way I can mount the SD card after it has been unmounted, is to insert a USB cable, go to notifications and select mount, or to power off my phone and then power it back on.
