Re: [EXTERNAL] Getting last Friday's date

Highly recommend having a date conversion aka "calendar" table.

You might check out this article from Gene Cobb
https://www.ibm.com/support/pages/system/files/inline-files/$FILE/Converting%20Legacy%20Date%20Fields%20to%20DB2%20Web%20Query%20Dates%20Part%20I.pdf

I've read a number of articles about them over the years, for various
RDBMSs.

One in particular stands out, but my google-fu is failing me this morning.

Thanks for that! Aside from being really fast, it also will give you as
many dates that fit as you want. Cool.

I use a table from IBM called DATE_CONV for a lot of my date converting
(JOIN is faster than converting). I think this was included with web

query

in QWQCENT library.

select dc_date from date_conv
where dc_date <= current_date and dc_day_name='Friday'
order by dc_date desc
fetch first row only;

Result is 2023-08-04

Of course, you can return your date in virtually any date format.

Subject: [EXTERNAL] Getting last Friday's date

I need to retrieve the date from last Friday. If it is Friday, I want

the

current date. Anyone have a routine that does that before I start
developing one? Seem like a good SQL problem but the program using it
would be in CLLE.

Thoughts?
