Author Can I change Data Type on DW automatically?

Hello everybody,

I have to chang a table column data type from int to char. How can I change
automatically the data type used on the datawindow without re-opening and
redesign the DW's?

I still use PB 6.5

Many thanks, Luca.

First why? Next I guess you could programatically export, change, import the
datawindown back on the fly, but again Why? Is this just one or a global
change? Sounds like maybe someone has to change a datatype across a large
application. There used to be a ton of search&replace programs on the web.

Export all your datawindows to textfiles, then open them with a good
texteditor (e.g. textpad), then you can do a search & replace with regular
expressions in all open files at once.

Thank Thomas,

I have tried exporting on srd files, make the changes and then re-import the
files on the same PBL but it seem not working.

Do I have to import the files on another PBL or what?

Thank you, Ciao.

Hi,
the question is, what is not working. Do you get any error messages? For my
substitutions I use PowerGen. Since we use CVS all our objects already
exist as textfiles, so I simply open the necessary objects in textpad do
the search and replace and then make a sync run via powergen on the pbls.
With powrgen you can also export all your objects in an application to
textfiles at once and also generate a .pbg file which is needed for
synchronisation.

No, its a simple export, change and import chain. Since we use PB 8 its also
possible to edit the source of an object in powerbuilder itself. But this
is only possible for one object at a time, so we use powergen together with
textpad.

Be also sure to do the correct changes, simply do the change for one object
in Powerbuilder and make a diff on the textfile before and after the
change, so you can be sure what you have to change in the textfile.

Practice on a test object, make sure you have the steps perfectly before
trying on 100's of objects. I wrote a tool years ago to do this, in PB but
can't find it! Search the web for PB Search & Replace.
