    Posted: 31 Jul 2007 at 9:08am
I am in the process of rewriting several reports that were originally written in CR6 and run from a VB6 app. In the report I'm working on now there is a comments field that is defined in the Oracle table as data type LONG.  All of the other comment type fields that I've been using are defined as VARCHAR2(2000) and they work fine.  Is there a trick to using a LONG data type?  I should also mention that they display just fine in the CR6 version, and redefining the Database field is not an option.
 
Any help would be greatly appreciated.

I am not a Oracle person but in looking on the web it seems this is  datatype that holds alphanumeric characters (a whole lot of characters).  So it is probably somewhat simitar to the Text datatype in SQL Server.

If that is true I would try the following in a formula

CStr({Yourfieldname}

 
It should convert it to a string which CR can read.
 
Best thought I have....

Thanks for trying to help.
 
Although your suggestion "CStr({Yourfieldname}" didn't work, your reply did get me thinkiing in another direction.
 
I went over to Business Objects and poked around until I came across a solution that made me wonder if my ohoice of OLE DB Provider could be the problem.
 
I was using "Microsoft OLE DB Provider for ODBC Drivers". 
 
I created a new Q'n'D (quick n' dirty) report using "Microsoft OLE DB Provider for Oracle" and the errant Oracle Long field was able to be displayed in the report.
 
Now if I can just figure out a way to change the OLE DB Provider in my real report.
 
Any suggestions?
 
Again, thanks for the help.

Glad to see that John got you on the right track. You can use Database > Set Datasource Location to change providers.

Thats the way it always happen you get an off track answer that leads you to the correct one.  That is the value of forums such as this one. Its a place to share thoughts that lead to solutions. Thanks again to Brian for hosting it.
 
Looks like you have what you need to go on to finishing the project and that is all that matters.
