<p>I am having fickle of problem in Oracle 9i</p>

<p>select 1"FirstColumn" from dual;</p>

<p>Oracle throwing error while executing above query. ORA-03001: unimplemented feature in my Production server.</p>

<p>The Same query is working fine in my Validation server. Both servers are with Oracle 9i</p>

<p>Any one have Idea what's wrong...? Is this something configurable item in Oracle server.</p>

What is the full Oracle version on both servers?  9i is a marketing label-- are you comparing a 9.0.1.x database to a 9.2.0.x database?
