I'm using SQLite (system.data.sqlite v. 1.0.60.0) on a Fluent NHibernate project.
I have one program that writes to the DB, and another that reads from it. Occasionally, I get SQLITE_BUSY exceptions, and I need to fix this.
I found several Google references to sqlite_busy_timeout, which (if I understand correctly) will cause SQLite to...

I'm creating a DB using SQLite from .NET, and then inserting 1500 records (15 columns, only 3 with information). At this point the database file size is 73mb!! (huge for the amount of information involved).
If I open SQLite Administrator, and do a Clear Database, it shrinks to only 142kb.
What it's doing that? Anyway to avoid it?

Trying to store property of C#/.NET type byte[] in SQLite. Here is my mapping:
<class name="MyClass" lazy="false" table="MyTable">
<property name="MyProperty" type ="BinaryBlob" access="property" />
</class>
In SQL server it works like a charm even without the explicit type="BinaryBlob" in the mapping. In SQLite I've tried various ...
I want to implement a function for System.Data.SQLite in C#. Implementing the SQLiteFunction interface is easy (seen examples over the Internet).
The question is where should I put the compiled code? Do I need the source to be compiled altogether with the System.Data.SQLite project? Do I have a better option, so that my functions will r...
I'm using SQLite.NET to access my databases, and in one particular case, I need to get a table schema because it's application-specific.
I've been looking through the SQLite.NET forum and google, and it seems very straightforward. If I have a table called MYTABLE, I should be able to do this:
DataTable dt = Connection.GetSchema( SQLit...
I have a Sqlite Database where I am enumerating my directory structure and inserting records into 5 different tables. Total Files + Folders count = 4000. Also there is nested loops. Can say all loops runs for 4000 times cummulative to insert the records. Earlier it was built with Sql Server where it was running absolutely fine. It was t...
Hey guys, I'm currently experiencing a very strange crash in Windows 7 in a C# Windows Forms application developed in Visual Studio 2008.
The app - which works great in both XP and Vista - never really opens; instead, a "this application has caused an error and has stopped working". I made a dummy application with the following source-...
Hello everyone,
This is my first application with a database. I'm using SQLite and Visual Studio. I have the database added, but how do I store and retrieve information from it? I'm using System.Data.SQLite as the .NET wrapper.
The wrapper obviously provides me with methods to create connections and execute queries, but is there an ea...
I consider to use SQLite in a desktop application to persist my model.
I plan to load all data to model classes when the user opens a project and write it again when the user saves it. I will write all data and not just the delta that changed (since it is hard for me to tell).
The data may contain thousands of rows which I will need to ...
I know this question has been posted here before, and I've trawled through as many answers as I could find, but I still can't get the simplest test in the world working.
1) I created my test and ensured it was working in in VS2008 and then opened the the solution in VS2010 (so it's all definlaty working, and all 3.5 code with all the as...

I have a list of items that I want to insert into the database but I do not want any duplicates. So I delete all the items and reinsert all. It's not the most efficient way but it's not many items so it works for me. But I get syntax error near "Insert". I do the following:
DELETE FROM Settings WHERE Type = 'Extensions'
