RE: Re: passing an array variable from a .Net middle tier to a da

Given that I've been developing in .NOT for the past 6 months, I figured I'd chime in here....

.NOT can call PL/SQL just fine. If you use Oracle's ODB.NET (that's Oracle Data Provider for .NET -- a free download from otn.oracle.com), you can use bind an array to a PL/SQL call. In fact, if you look on OTN, you can find an article titled.

        Bind an Array to an ODP.NET Database Command

That said, I have never used the version provided by Micro$oft.

hmm....

earlier in the year i was on a project where I wrote alot of backend PL/SQL that was called through the middle tier. I have no idea how this works. I just assumed it came straight through .NET.

any idea how they might have done that? The front end was a .NET architecture. Sorry for being vague, my extent of knowledge on .NET ends with how to spell it.

If you cant call PL/SQL from .NET than that is a huge weakness in comparisons to java. Will microsoft add featurse to all this? I would think they might not because they want people using SQL Server.

Our .NET architect swears by it and claims .NET has alot of advantages over java.
