hello Community

I have to carry out a massive conversion of the datawindows of my application to bring it from oralce to postgresql.

Unfortunately, the application was developed by setting the parameter of 'Outer Join Syntax' to 'PB'.

This annoys PostgreSQL. I have to convert that parameter to 'ANSI'.

 

Which is the best strategy?

 

Thanks in advance for your reply

Hi Gimmy;

   The LibraryExport () and LibraryImport () commands work on DW objects. So you could write a utility to walk through all the DWOs  via the libraryDirectory() command. Changing all the PB join syntax to ANSI.

Food for thought. HTH

The only caveat is if the DWO uses a real SQL statement vs a "PBSELECT". The latter means that the DWO creates the various DML commands "on-the-fly". So changing the join type in the DWO source should be all you need to do. However, if the previous PB developers "hard coded" the SQL statement then you would need to *manually* rewrite the SQL statement. When I taught the PB courses for PowerSoft & then Sybase, I always stressed about using the PBSELECT and never hard coding the SQL in a DWO for just this type of reasons. At least with your utility though, you can identify the non-PBSelect DWOs and then create a manual ToDo list.

BTW, I created a PB utility for doing almost all of what I described. You are welcome to download & modify it for your purposes.
