DotNet DataSet To CF Structure of Queries

Posted in ColdFusion by rip747 on October 30, 2006

UPDATE: I don’t want to get comments or hate mail saying that I stole this code from Joe and called it my own. I give Joe credit and I even emailed him about it.

I have no idea why Joe Rinehart never submitted this little gem to CFLIB.org (probably because it takes 6 months for your submission to show up). Any who, this is function that he wrote a while back that will take a DotNet Dataset and convert it to a CF structure of queries. I corrected some bugs (it would bomb if there was no record returned) and updated it (it now automatically converts xs:dateTime columns to CF datetime) and submitted it to CFLib. Hopefully someday it will make it into a library there, but for the mean time you can download it below.

I just want to say that Joe Rinehart deserves all the credit for this one. Thanks Joe!!!
