How can I create a new SQLite database, with all tables, on the fly? [duplicate]

Answer 1

For some assistance, you could check out the Public Domain project a friend of mine made: www.codeplex.com/publicdomain.

Along with tons of other useful utilities, look into the Data.SQLHelper.GenerateCreateTablesQuery(DataTable[] tables). Just use SQL for the database type.

Answer 2

You could write a script to do it all, but you could also have a unit test project that tests your database interface. If you do that, then you'll want to be able to create a test database with dummy data for tests only. Basically, my point is that if you use a script file to create the application data and if you want to add unit tests, then you'll need to either have another script file for them, or you will want to create your database in code.

I would advocate the authoring of a class in your code that can create the database schema on the fly for the application and unit tests. Then if you change the schema, you only have to worry about it in one place and not have to deal with things getting out of sync (hopefully).

Since you're using SQLite and C#, I recommend giving SQLite.NET a try. It has made my life a lot easier, and I've been very happy with it thus far.

With SQLite.NET, you would create an SQLiteCommand, set its CommandText to "CREATE TABLE (your schema here)", and then call ExecuteNonQuery to generate the table.

Maybe this will help:

SQLiteConnection.CreateFile("c:\\Ik.db");

Create a new database on the fly and execute a query on it. The query should be something like this:

CREATE TABLE IF NOT EXISTS [Setting](
[ID] INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT,
[Key] NVARCHAR(2048) NULL,
[Value] NVARCHAR(2048) NULL
);
