Re: [Zope] DCOracle 2 and long text fields..How to use them?
Hello Chris, You have to use bind-variables or a stored procedure.

Right, bind vars are the way to go. Unfortunately, Zope doesn't create bind variables for SQL methods, so you have to do it via an external method.

Stored procedures worked excellent for me. Less hassle than external methods in some cases , especially if (like me) you have a Database Administrator to handle them instead of doing it yourself.. ;-) Lazyness is a great virtue on or about, Monday, May 06, 2002, we have reason to believe that Matthew T.
