Unable to create schema with Castle ActiveRecord
I'm trying to get started with Castle ActiveRecord (following the "Getting started with ActiveRecord" screencast).
I created two ActiveRecord classes, one of them named User
. I added the relevant strings to the app.config
file, and I initialize using:
var config = ActiveRecordSectionHandler.Instance;
ActiveRecordStarter.Initialize(typeof(User).Assembly, config);
ActiveRecordStarter.CreateSchema();
Unfortunately, when I run this, I get the following exception:
Unhandled Exception: Castle.ActiveRecord.Framework.ActiveRecordException: Could not create the schema ---> NHibernate.HibernateException: Incorrect syntax near the keyword 'User'. ---> System.Data.SqlClient.SqlException: Incorrect syntax near the keyword 'User'
I uploaded a small reproduction to http://bitbucket.org/hmemcpy/general, could someone please tell me what have I done wrong?

'User' is a reserved word in SQL server, the SQL command being executed is:
create table User (Id INT IDENTITY NOT NULL,
UserName NVARCHAR(255) null unique,
primary key (Id))
It's illegal to name a table User in SQL server, but it is legal to name it [User].
create table [User] (Id INT IDENTITY NOT NULL,
UserName NVARCHAR(255) null unique,
primary key (Id))
As a solution you can define different names for tables and columns named by reserved words:
[ActiveRecord("[User]")]
public class User : ActiveRecordLinqBase<User>
{
[PrimaryKey]
public int Id { get; set; }
[Property(Unique = true)]
public string UserName { get; set; }
[HasMany]
public IList<Activity> Activities { get; set; }
}
When using a [ ] around the table name, reserved names are allowed. The same is relevant for relation columns:
[ActiveRecord]
public class Activity : ActiveRecordLinqBase<Activity>
{
[PrimaryKey]
public int Id { get; set; }
[BelongsTo("[User]")]
public User User { get; set; }
}
Of course, any other name like [ActiveRecord("SomeUser")]
will work.
