Paul,

Actually in the DDS world you can use the command CHGPF and it 
automatically recompiles the file and migrates the data.

The problem with DDS vs SQL is that DDS doesn't contain all of the 
physical constraints, referential constraints, etc, and with DDS you would 
need a make program.  And, since DDS doesn't support many of these new 
features, then people get into a habit of not using them.

Once again, it's the use of the tool and not the tool itself that is a 
problem.  If you use a RUNSQLSTM or some such utility against stored SQL 
source then you will be no worse off than using DDS.  And probably better 
off because of the storage of the constraints, etc.

Re: changing keys of a physical file






Rob--

I want the original source, so when the programmers decide to change 
things around they can start from the last known good point.

I suppose that adding a field to a file using SQL to alter the table 
is 'better' than changing the DDS and recompiling the file, then 
migrating the data...
