Re: Getting the number of records in non-keyed logical files?

[Luis Rodriguez <luis.rodriguez2@xxxxxxxxx>]

Elvis, Rick:

Thanks for your answers.

  That's what I thought of, although there is (was?) always hope :-) ?  


  I wonder what would be faster, using a DDS-based LF or Elvis' proposed 
solution? This CL is executing a 5 sec. loop, and I wanted to avoid the 
sequence of CALL/Open Cursor (or file), etc. 


    Thanks again, 


  Luis Rodriguez

Luis,

Because views are merely SQL statement containers there are no records to 
count.  Each time the view is accessed the SQL statement is executed to 
retrieve the resulting data set.  To get the number of records you will need to 
count the number of records returned by the SQL statement contained in the view 
as posted by Elvis.

I realize it's not purely CL solution, but if ILE is not out of the realm of 
possibilities doing a CALLPRC to a module written in HLL with embedded SQL 
following statement would be my choice:

SELECT COUNT(*) FROM YOURVIEW

Hi all,

Does anybody know how to get the number of records in non-keyed logical files 
(e.g. SQL views)?

RTVMBRD / NBRCURRCD can only get the number of records for keyed LFs. I would 
like to determine, in a CL program, the number of records in a SQL view.


Thanks,

Luis Rodriguez
