Nhibernate and sql scripts

Question

Dont suppose anyone knows how to execute a sql script from nhibernate. Ive got some static data that I need in a database, that is contained, in a staticData.sql file. When I run my integration tests, I recreate the database with the schema export command, and I need to run this data in. I realise I can get it in using .net, but Id really like to only have one data access technique in my project...

Thanks

Try using NHibernate.ISession.CreateSQLQuery(string queryString)

    private NHibernate.ISession session; // Initialized somewhere

    public void ExecuteSQLFile(string sqlFilePath)
    {
        string sqlScript;

        using (FileStream strm = File.OpenRead(sqlFilePath))
        {
            var reader = new StreamReader(strm);
            sqlScript = reader.ReadToEnd();
        }

        var regex = new Regex("^GO", RegexOptions.IgnoreCase | RegexOptions.Multiline);
        string[] lines = regex.Split(sqlScript);

        foreach (string line in lines)
        {
            IQuery query = session.CreateSQLQuery(line);
            query.ExecuteUpdate();
        }
    }

Here is the documentation: Chapter 16. Native SQL

There's nothing wrong using plain ADO.NET to insert data into the database in integration test. For batch inserts it is even better than NHibernate. The way you put your database in a known state for a test doesn't matter that much, what is important is to test the way you access your data in the application.
