nhibernate connecting to legacy database - nhibernate

Question

I am connecting to a legacy sqlserver database. One of the tables has column name "Primary". The scripts are failing due to that.
Script generated by nhibernate:
SELECT locations0_.CustomerID as CustomerID1_, locations0_.LocationID as LocationID1_, locations0_.LocationID as LocationID2_0_, locations0_.Primary as Primary2_0_,locations0_.CustomerID as CustomerID2_0_
FROM dbo.tblLocation locations0_
WHERE locations0_.CustomerID=?
Class:
public class Location
{
public virtual int LocationID { get; set; }
public virtual Customer Customer { get; set; }
public virtual int? CustomerID { get; set; }
public virtual string LocationName { get; set; }
public virtual string Address1 { get; set; }
public virtual string Address2 { get; set; }
public virtual string Address3 { get; set; }
public virtual string City { get; set; }
public virtual string StateOrProvince { get; set; }
public virtual string PostalCode { get; set; }
public virtual datetime? LTimeStamp{ get;set; }
public virtual bool Primary { get; set; }
}
Map:
public class TblLocationMap : ClassMap
{
public TblLocationMap()
{
Table("tblLocation");
//LazyLoad();
Id(x => x.LocationID).GeneratedBy.Identity().Column("LocationID");
References(x => x.Customer).Column("CustomerID");
Map(x => x.LocationName).Column("LocationName").Length(50);
Map(x => x.Address1).Column("Address1").Length(200);
Map(x => x.Address2).Column("Address2").Length(200);
Map(x => x.Address3).Column("Address3").Length(200);
Map(x => x.City).Column("City").Length(100);
Map(x => x.StateOrProvince).Column("StateOrProvince").Length(100);
Map(x => x.PostalCode).Column("PostalCode").Length(20);
//Map(x => x.Primary).Column("Primary").Not.Nullable();
//Map(x => x.LTimestamp).Column("LTimestamp");
HasMany(x => x.Contacts).KeyColumn("LocationID");
}
sql:
CREATE TABLE [dbo].[tblLocation]
(
[LocationID] [int] IDENTITY(1,1) NOT NULL,
[CustomerID] [int] NULL,
[LocationName] nvarchar NULL,
[Address1] nvarchar NULL,
[Address2] nvarchar NULL,
[Address3] nvarchar NULL,
[City] nvarchar NULL,
[StateOrProvince] nvarchar NULL,
[PostalCode] nvarchar NULL,
[Primary] [bit] NOT NULL,
[RecTimestamp] [timestamp] NULL,
(
[LocationID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO
GenericADOException:

Answer 1

I suspect Primary is a reserved word and is not getting escaped properly, therefore try implicitly escaping the column name with back ticks....
e.g.
Map(x => x.Primary).Column("`Primary`").Not.Nullable();
NHibernate will automatically swap your backtick with square braces if you are using MsSql server [Primary]
Strange that the schema is generating square braces but the select SQL isn't.
