Re: Assigning Field Name

[jfinney@xxxxxxxxxxx]

Hi Rob

I'm not sure with embedded SQL in the program. If the file changes, would one
have to re-compile the RPG program (like you would if the QADBIFLD file was
declared on the 'F' spec) ?

In any case, in light of the Spock quote, why not use the list object API's to
retrieve the data needed :

No function checks on changed files (and QADBIFLD has changed a few times since
v3r7)
Since it's an API, it runs below the MI

Regards
John.

1)  Don't waste your time by doing a DSPFFD to an outfile.  The file
already exists, and is constantly updated by the system.  The name of the
file is QADBIFLD.  Do a DSPDBR QADBIFLD also.

2)  Instead of &FLDNAM, let's use DBIFLD, (to use the file QADBIFLD).  By
the way, you're not insisting on using 'stone knives and bearskins' are
you?  (Quoting Mr. Spock from Star Trek.)

H ALWNULL(*INPUTONLY)
Fqadbifld  IP   E             DISK
DStmt             S            500A

C                   eval      stmt=*blanks
 /free
   Stmt='Select ' + dbifld + 'into :' + %trim(dbifld) + ' from ' + DBIFIL;
   *inlr=*on;
 /end-free

 * Fix the SQL0312 error in the below, and you'll have it whipped.
 * Got to get back to work.
C/exec sql
C+ Prepare S1 from :Stmt
C/end-exec

C/exec sql
C+ Execute S1
C/end-exec

C     DBIFIL        DSPLY     DBIFLD

Yes ..

this happens all the time.
for example,

programs that DSPFFD to an outfile and then use it.
eg,  IF (&FLDNAM = 'DBMAST') then(goto DBMAST)


However, i suspect your question needs more explanation to get the answer
you are trying to elicit.
