NHibernate works without mapping

ISQLQuery query = Session.CreateSQLQuery("SELECT p.*, c.* FROM Product p Left JOIN Product_CustomField c on p.ProductId=c.ProductId");
query.SetResultTransformer(NHibernate.Transform.Transformers.AliasToBean(typeof(Product)));
IList resultList = query.List();

Notes:
Add CusTomField1..5 into Product Class,not need declared in .hbm.xml

Combine with ScalarFields
public class SqlRepository {
...
public IList ListEmployees() {
using (ISession session = _sessionBuilder.GetSession()) {
return session
.CreateSQLQuery(@"
SELECT No_ AS EmployeeNumber, [E-mail Login] AS Username
FROM Employees")
.AddScalar("EmployeeNumber", NHibernateUtil.String)
.AddScalar("Username", NHibernateUtil.String)
.SetResultTransformer(Transformers.AliasToBean())
.List();
}
}
}


Add nHibernate mapping at run time
ISessionFactory sf = new Configuration()
.AddFile("Product.hbm.xml")
.AddFile("Category.hbm.xml")

Postgres configuration

classical paths

# vi /etc/postgresql/8.2/main/postgresql.conf
# vi /var/lib/pgsql/data/postgresql.conf
# vi /opt/Postgres/8.4/data/postgresql.conf


Enable Network:

listen_addresses = 'localhost' to listen_addresses = '*'

You must also have appropriate entries in pg_hba.conf for hosts and
authentication type. You could use something like:

#TYPE DATABASE USER ADDRESS METHOD
local all all password
host all all 127.0.0.1/32 password
host all all 192.168.1.0/24 password

Next line allow all ips
host all all 0.0.0.0/0 md5

Postgres save images


CREATE TABLE images (name text, img bytea);



File file = new File("image.gif");
FileInputStream fis = new FileInputStream(file);
PreparedStatement ps = conn.prepareStatement("INSERT INTO images VALUES (?, ?)");
ps.setString(1, file.getName());
ps.setBinaryStream(2, fis, file.length());
ps.executeUpdate();
ps.close();
fis.close();


setBinaryStream(), transfers a set number of bytes from a stream.
setBytes(), use this method if the contents of the image was already in a byte[].

Retrieving image

PreparedStatement ps = conn.prepareStatement("SELECT img FROM images WHERE name=?");
ps.setString(1, "image.gif");
ResultSet rs = ps.executeQuery();
if(rs.next()) {
byte[] imgBytes = rs.getBytes(1);
}
rs.close();
}
ps.close();


You could have used a InputStream object instead.

Alternatively you could be storing a very large file and want to use the LargeObject API to store the file:


CREATE TABLE imagesLO (imgname text, imgOID OID);

To insert an image, you would use:



conn.setAutoCommit(false); // All LargeObject API calls must be within a transaction

LargeObjectManager lobj = ((org.postgresql.PGConnection)conn).getLargeObjectAPI();

//create a new large object
int oid = lobj.create(LargeObjectManager.READ | LargeObjectManager.WRITE);

//open the large object for write
LargeObject obj = lobj.open(oid, LargeObjectManager.WRITE);

// Now open the file
File file = new File("image.gif");
FileInputStream fis = new FileInputStream(file);

// copy the data from the file to the large object
byte buf[] = new byte[2048];
int s, tl = 0;
while ((s = fis.read(buf, 0, 2048)) > 0)
{
obj.write(buf, 0, s);
tl += s;
}

obj.close();

//Now insert the row into imagesLO
PreparedStatement ps = conn.prepareStatement("INSERT INTO imagesLO VALUES (?, ?)");
ps.setString(1, file.getName());
ps.setInt(2, oid);
ps.executeUpdate();
ps.close();
fis.close();

Retrieving the image from the Large Object:


conn.setAutoCommit(false);

// Get the Large Object Manager to perform operations with
LargeObjectManager lobj = ((org.postgresql.PGConnection)conn).getLargeObjectAPI();

PreparedStatement ps = con.prepareStatement("SELECT imgOID FROM imagesLO WHERE imgname=?");
ps.setString(1, "image.gif");
ResultSet rs = ps.executeQuery();
if (rs.next())
{
int oid = rs.getInt(1);//open the large object for reading
LargeObject obj = lobj.open(oid, LargeObjectManager.READ);

//read the data
byte buf[] = new byte[obj.size()];
obj.read(buf, 0, obj.size());
//do something with the data read here
obj.close();
}
rs.close();
}
ps.close();
