Using NHibernate to execute DDL statements

How can I execute a DDL statement via NHibernate?

To be clear, I don't want to auto-generate my schema from my mapping files. My DDL is stored in plain text files along the lines of:

CREATE TABLE Foo (Bar VARCHAR(10))
GO
CREATE TABLE Hello (World INTEGER)
GO

I want to cycle through these in order and execute each of them. I could just open a SqlConnection and execute via a SqlCommand but I'd like to go through NHibernate if there is a nice way to do this. This is mainly because I want to remain as database agnostic as possible: I have a SQL db now but I might need to implement Oracle or DB2 later...

I'm using .Net v3.51 and NHibernate v2.1. I looked at the NHibernate SchemaExport class but couldn't see a way to use this for this purpose.

Solution

  • You can get an IDbConnection from an ISession's Connection property but you'll need to do this with SqlCommand. Executing DDL is outside of NHibernate's scope.
