Although there's an answer to this question here the circumstances are different however. For instance, in one application System.Data.SQLite works perfectly while in this one keeps on throwing this exception on the following line: SQLiteSync.SqliteClientSyncProvider clientSyncProvider = new SQLiteSync.SqliteClientSyncProvider(connStr...
Ok, so currently I have this code in my program: 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...
I am creating an android app that is basically a listing of information on Mushrooms. I get this information from an sqlite database. I have a global singleton with a services class inside it in which I use to access my db. Almost every activity accesses the db. Is it better to leave my db open all the time or open and close it as I ...

Here is the line I have to create an instance of the ExpandableDataAdapter: ExpandableDataAdapter confDataAdapter = new ExpandableDataAdapter( t...
Hi Friends, Lets say , I have an Mobile App (iPhone or Android). When I upgrade the App to its version, does the Sqlite data that my earlier version had would be wiped out or not? ...
I'm using Django with an sqlite backend, and write performance is a problem. I may graduate to a "proper" db at some stage, but for the moment I'm stuck with sqlite. I think that my write performance problems are probably related to the fact that I'm creating a large number of rows, and presumably each time I save() one it's locking, u...
I would like to verify my Core Data store (SQLite file) before loading it so that if there is any corruption, the app won't simply crash and burn. Using the iPhone SDK, is there a way to verify an SQLite file (1) generally that it is not corrupted, and (2) more specifically, whether or not the SQLite file matches one of the possible data...

I have an image file stored on a remote server. I only have HTTP access to the server, so I'm getting its content using file_get_contents(URL) I need to store this content in a local sqlite3 database in a field of type 'blob'. I'm using the PDO object to connect to the database, and I'm using $db->exec("INSERT INTO myTable (myImageBlo...
Hi everyone, I guess the best thing to do is to show the code what I'm doing at the result: This works: if (sqlite3_column_text(statement, 0)) { [marker setObject:[NSNumber numberWithInt: sqlite3_column_int(statement, 0)] forKey:@"id"]; } This always returns false for the if statement: if (sqlite3_column_int(statement, 0)) { ...
Hi, I am evaluating the SQLite database for my requirement. Do SQLIte support the store procedures ? If yes then what is the limitations? Does SLIte support the range? Thanks Saurabh ...
Lets say I have a database table which consists of three columns: id, field1 and field2. This table may have anywhere between 100 and 100,000 rows in it. I have a python script that should insert 10-1,000 new rows into this table. However, if the new field1 already exists in the table, it should do an UPDATE, not an INSERT. Which of ...
It seems that sqlite won't allow me to create a temporary view in a read-only db. Am I missing something? If it's TEMPORARY, I figured db connection mode shouldn't matter. I even specified "PRAGMA temp_store = MEMORY" -- it didn't help. Is there a reasonable alternative to using views? ...
So I've recently completed this tutorial and it works great, but I'm a little stuck on reading the data from my database. I'm now reading from the database file thanks to Orsol by using this tutorial but I'm looking now for a method I can call which will return me the values of a given field. Or at least a method that let's me execute S...
For example, I want my users to be able to click a button "Get new quote" which will start a new row in the the database for data to start being stored, but I'm unsure of how to store activity independent (or cross activity) data, like the _id of the row, which I will need to requery and update the row when new data becomes available on ...
I have an app which uses a large amount of data which has been compiled outside the app (on my main PC). The app is for my personal use so there are no complications with having to distribute data updates to other users. However, I am currently following a very convoluted and time-consuming procedure each time I want to update the data, ...
I have a SQLite table with a field named FullFilename. Now, I want to select the rows of files in a certain folder. Let's say the table contains: c:\folder\file1.jpg c:\folder\file2.jpg c:\folder\subfolder\file1.jpg c:\anotherfolder\file1.jpg And I want to select only the rows with files in "c:\folder\". Not in a subfolder "c:\folder\...
Hi again people of stackoverflow. I have a routine that has a step that I find unnecessary lets say you want to get all the images from a gallery, and limit a certain number of images per page. $db = PDO object $start = (pagenum x images per page) $limit = (images per page) $itemsdata = $db->query("SELECT id,name FROM gallery LIMIT $sta...
I'm a newbie with DBLink and Sqlite. When DbMetal generates Nortwind.cs (C#) it marks some methods with a Table attribute: [Table(Name="main.Categories")] // C# After I used DbMetal to create a Nortwind.vb (VB.Net) file, the test program aborted because there was no table named "main.Categories". However, when I removed "main.", it ...

First i build my scaffolds, add the references to migration files, add belongs_to has_many to models than get my database up and runinig with basic rake db:migrate command. And then it doesn't work, I guess there is a missing step which i cannot figure out :S By the way i ...
