Hi Avner,

if you are in the DTD editor,

use the menu File=>Duplicate

Hi Uli

what i need is to Export the dtd and it's mapping to the same model but in another database what i use for production

so it is eporting from dvelop db to production db

now , i try to do it using Convert  Data utility

the problem was an error message "OUCDTYP IS MISSING" SO IT DIDN'T CREAT THE O TABLE BY DEFALT

SO I HAD TO CREAT MANUALY A DTD OBJECT CREAT A BIG ONE WITH NESTING AND BIG MAAPING DATA USING THE WIZARD TOOL

THIS DID MANAGE TO  ALTER UNIFACE TO CREAT THE  "OUCDTYP" EXTENTION TABLE FOR THE "UCDTYP" TABLE AT THE DICT MODEL

AND AFTER THAT WAS DONE I  used the Conver Data utiluty and the import ,compile and /urr

and all is well

but it took me good 4 hour's to figure it out look in the : internet  , uniface help , and   again get in the uniface lab mind

Hi Avner,

looks I misunderstood the context of your question:
seems you had a lot of work fighting with the internals of uniface; overflow tables are real killers.

Another option beside the /CPY might have been:

- export the complete model using the standard export functionality.
- take the export file into your editor and delete all packages which are not DTD related
- import this condensed export in your new database

This may do the job as well (if not, please inform us).

To export just the DTD-infos from a model
I wonder if it would be a good idea to provide a tool
where you can filter the information exported.

What do You think about that?

Hi Uli

i think that uniface should change the  consept about how they construct the DTD'S utility

I also do a lot of stdy and work testing uniface 9.4 beta 3

and i found out that it is complitly the same as uniface 8.4

the path to get to DTD'S is not strait forword , there is no mention of DTD'S at the export form

and i think that working with DTD'S is as importand as working with : WEB SERVICE,WEB SERVER . because it an inegral part of it

we have to use DTD'S in an intensive way as all the world  is using  , web services, XML to communicate

Hi Avner,

Following the "di IT ourself" (dITo) initiative,
This is a way to get more support from the current IDF:
Use a special data-model called DTD_TRANSFER to export/import DTDs only.
"Duplicate" allows transfer from/to this model.

As "the lab" sees/implemented DTDs as part of the data model,
there is not so much support splitting the contents of a model for tenasfers.
Same goes if all you want to transfer is a single entity
because you have added some fileds.

Success, Uli

P.S. by the way: have you seen my DTD editor in the download area?

Hi Uli

now that is a good idea , i will try it , thank's
