I have the data in the android(Sqlite Database).How to transfer this database data's to the System Database( like Access or SQL Server).After Transfer this data's i have to use the data in the System.I am new to android. Can anyone help me.
Note:
If the android device have the Database db1.I wish to use the db1 data in the Desktop Application .
You can copy the database file to the desktop, and then open it there with SQLite. You could then export the data to CSV file, and import this one in the database of your choice.
The db file is present in "/data/app/" Your Application Package directory "/databases/" Your DB File.
Copy the file from this location and use the steps provided by Thomas Mueller.

For a schoolproject I have converted a php database from MySQL to MySQLi to use it in my android application.
I've looked into creating a android database using head's first book on android (2017) and according to that I need to manually create and insert every record in the database, but I already have all the data needed and one table even has 113 entries that need to be inserted.
Isn't there a way for me to import the existing database without completely creating it all over again?
Use SQLite browser , hope it helps .
Export SQL file from MySql and put it into assets folder. Read sql file from assets, use 'db.execSQL' method to create and insert all records of sql file. Some of the 'keywords' are working in SQLite of MySql so firstly remove these keywords from file.
I want to upload local sqlite database file at server but in sql format. Is it possible to directly save it in mysql supported format? The file is uploaded successfully on server but its just a flat file of sqlite db. When i open it in editplus or import it in phpmyadmin, it shows error. But when I manually export the database from sqlite manager in .sql extension, it successfully gets open in readable format in editplus. Please help me with this problem. Thanks in advance !
AFAIK you are talking about two completely different things.
Its like comparing a DB dump file to a properly exported file like an xml file with schema and data information from Oracle or MySql
When you export you get a file with or without .sql extension and it means a file with set of queries like DDL or DML create,insert etc. That may be sequentially run to execute all the commands in it and provide you with the right schema and data present in that file.
Whereas a DB file that is created via app is specific to the device and is an .sqlite file which is specific to sqlite browser and that may read it and not a set of queries only that you may open in edit-plus or a text editor.
Sqlite DB file that you find on your device is dynamically generated pages to maintain the integrity of the db.
For more info you must read,
Format of sqlite database
Sorry I don't have code but the idea is,
--Edit with algo--
Assuming you have the create commands for all tables and constraints with you , as they are not going to change most of the time.
You may use this function as a Utility to create and maintain the sql
command list for you parallel to the db you have.
void createExportCommands()
{
...
- Read all tables one by one using a `Cursor`
- Based on specific tables/columns create queries
i.e. String query="insert into "+your_table+" values("+cursor.getString(0),....+");";
- Write this data into a file called export_data.sql and keep updating it in background
}
Perhaps its not the best approach but it will solve your issue.
I used PhoneGap to create a Sqlite db and access it to read data. So I want to find out where the Sqlite file is located in my android device. Please show me
If you use phonegap then your database will be at location
/data/data/package-name/app_database/file__0/0000000000000001.db
And all your tables will be stored there....
If your package is com.exampl.hello then
/data/data/com.example.hello/databases/databasefile
where databasefile is the name of your database.
I've been working on testing trying to get an SQL database off of a website then take all the records and store them into arrays. Problem is that I've tried a ton of downloading methods and I keep getting hit with an error with opening the SQL database. I can't tell if this is actually downloading, if the database is corrupt (I checked it and it looked correct) or if my queries are messed up. Bear with me because I am just learning SQL and Android development.
The file at the link you provide is not a SQLite database. It's an ASCII file that contains SQL statements for creating a database and inserting content. There's no straightforward way to execute the content of that file in an Android app.
To make this work you need to create an actual SQLite database from your SQL file. To do that, install SQLite for whatever your desktop OS is and use this command:
sqlite> .read <filename of your SQL file>
Replace the file on your website with the SQLite file that creates. That should get you past the open error.
What are you doing here is download your database from url and stored it in sdcard.
Now you should open a empty database in your app and then copy your database in your app database and then try to open it.(you are not copying the database) the default location of database is
private String DB_PATH = "/data/data/your package name/databases/";
I have sqlite database in my system i need to add this data base to the device(in the application location).How to do this ????
You basically add code in your application that creates the database the first time it's used (Android will take care of the internals):
http://developer.android.com/guide/topics/data/data-storage.html#db
If your database is not very big - just place your DB file into assets and then during first run your application should just copy SQLite DB file from assets directory to your application data storage. See here
