Nested Select Statements

Hello,

I am connecting to a Microsoft SQL Server 2008 database using unixODBC and
FreeTDS on PHP. Everything was going well until the ORM library that I'm
using (Doctrine) attempted to perform a select statement while cycling
through the result set of another query. I received the error:
"SQLSTATE[24000]: Invalid cursor state: 0 [FreeTDS][SQL Server]Invalid
cursor state (SQLExecute[0] at ../pdo_odbc/odbc_stmt.c:254)"

After doing some research, it appears that this behavior is by-design in
FreeTDS (http://www.freetds.org/faq.html#pending). Is this error that I'm
getting because of this implementation detail? If so, are there any plans
to change this behavior? If not, does anyone have any recommendations for a
driver I could use with PHP that would allow this behavior?

Under normal circumstances, I would simply adjust the code myself. However,
since I'm using someone else's library, I don't exactly have this luxury.

Any suggestions are appreciated.
Thank you!
