Here's the sequence to get this re-create this problem.
1) install orion server
2) get release 1 jdbc drivers from microsoft
3) install confluence under orion
4) define data-sources in orion
5) create empty db in ms sql server
6) startup orion, setup confluence to point to new empty db
7) login to confluence after setup, create 1 space
8) exit confluence, shutdown orion and restart
9) try to access confluence and get this error:

org.springframework.jdbc.UncategorizedSQLException: (HibernateAccessor): encountered SQLException [[Microsoft][SQLServer 2000 Driver for JDBC]ResultSet can not re-read row data for column 2.]; nested exception is java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]ResultSet can not re-read row data for column 2.

From microsoft, the problem is the following:
For nvarchar,image,text types the driver throws exception when the order you retrieved is differ from the order you access the result

There are three tables in confluence with type 'Text' - CONTENT, EMAILTEMPLATES, and PAGETEMPLATES. I'm guessing the problem is with one of these tables. Here is more of the server log error:
