RE: substring date fields in logical files

Yes you can James...........

Here is an example of SST out parts of a field, in this case it is a date
field.

        ==================================================================
       *
       *   The field TRSHFD is a date field with CCYYMMDD (20010801).
       *
       *   Substring out the century and year from TRSHFD.
      A            FCCYY              I      SST(TRSHFD 1 4)
       *
       *   Substring out the month and day from TRSHFD.
      A            FMMDD              I      SST(TRSHFD 5 4)
       *
       *   Sort by MMDD first and then the CCYY.
      A          K FMMDD                     DESCEND
      A          K FCCYY

I hope this will help you.

Subject: substring date fields in logical files


I have a physical file that contains a date field in it.  I want to create
a logical file over it that is keyed by just the year and month portion of
the date field.  The DDS manual tells me that I can't use SST on date
fields.  Anyone know a way I can create a field in a logical file that is
a portion of a date field?
