Hi!
I'm working with Hibernate and Oracle 8.
I have a problems working with Blobs...

The sourcecode is:

Blob data;

public Blob getData( )
{
return data;
}
public void setTheData(byte[] theData) {
this.data = Hibernate.createBlob(theData);
}

The error is:
Could not synchronize database state with session
java.sql.SQLException: operaci

Try disabling JDBC batch updates. Set in your properties hibernate.jdbc.batch_size = 0

HI!
I did this and now I have other problem:

Commit failed
java.sql.SQLException: ORA-01010: invalid OCI operation

Oracle BLOBs are allways something good for a lot of fun. Please read http://www.hibernate.org/56.html and try the solutions presented there, I think this works, at least most of the time ;)
