2. Declare a Model DSPDBR outfile
3. Execute DSPDBR command and store the results in out file
declared in step 2.

Answer / abhishek
Hi Friends,
There is no command which directly deletes all the
depandent logical.
Regarding use of option delete dependant file under CHGPF:
Consider example below:
Lets say PF has 3 fields... Fld1, Fld2 & Fld3
First LF has key field as Fld1.
Second LF has key field as Fld2
1. Pl note that delete dependant file option will only come
when you specify the source name and libr along with object
name & libr.
2. Lets say, I have removed one of the field named Fld2
from my PF. Obviously, my second LF is of no use, as field
use by this file is removed. Now, if I specify, DELETE
DEPENDANT FILES as *YES under CHGPF command, it will first
change my PF properties (as expected) and will also delete
SECOND LOGICAL FILE (as it has a dependant field).
Hope, it helps. Cheers.

run the following sql:
drop table <filename> cascade;
And all the logicals based on the file being deleted will
magically disappear.

i have copied a pf from another one and after updating that
pf ,i used it in my program.It was giving me an error.
After compiling the program i have found that it was
refering to previous record name.
Then in command line in CHGPF i mentioned program name and
source file name.
you will get 'Delete dependent logical file' option,make
it '*yes'.
That is how i deleted all the references.
