RE: SQL String Question -- MIDRANGE-L

Missed the second part....

LRDTE IN (20081231, 20091231, 20101231, 20111231)

I think what you are asking for is:

Mod(lrdte, 10000) = 1231.

HOWEVER, please note that using a function on the LRDTE column will preclude the use of an index over
that column for selection. You might end up forcing a full table scan.

You could do something like so instead:

LRDTE in ( (year(current_date) * 10000) + 01231,
(year(current_date) * 10000) + 11231,
(year(current_date) * 10000) + 21231,
(year(current_date) * 10000) + 31231 )

Subject: SQL String Question

The code below is embedded in an RPG/400 program running in V5R1. It is
accessing BPCS customer orders. I need to increase the level of
sophistication.

I have one routine to get grand total of orders, then others to get
various exception totals, such as FORECAST, Dec-31, various combinations,
which I subtract from total to get "real" customer orders that will be
shipped the customer.

We have in HCPO (customer purchase order) field the word FORECAST for the
purpose of telling MRP to order raw materials.

Some HCPO contain the word FORECAST then some other stuff ... I urgently
need to learn how to select on the basis of the first 8 columns of the
field HCPO with this text, or re-write the program a different way.
Actually several programs, which are using the same technique.

instead of              LORD IN (SELECT HORD FROM ECH WHERE
HCPO<>'FORECAST')

We use the last day of the year to contain Estimated Annual needs of the
customer that have not yet been filled. So I have the following code.

LRDTE IN     (20081231, 20091231, 20101231, 20111231)

I could advance dates in programs like this each year, if I remember them
all, but I would prefer to select on the basis of the last 4 digits of the
8 digit date.

C/EXEC SQL
C+ SELECT SUM(LQORD-LQSHP)
C+                             INTO :ORDWRK
C+ FROM            ECL WHERE LPROD=:ITEM
C+                        AND LCUST=:CUST
C+                       AND LICFAC=:FAC
C+                        AND LWHS>=:YWHS
C+                        AND LWHS<=:ZWHS
C+                         AND LID='CL'
C+                      AND LCLAS<>'11'
C+                      AND LRDTE IN
C+          (20081231, 20091231, 20101231, 20111231)
C+                      AND LORD IN
C+           (SELECT HORD FROM ECH WHERE HCPO<>'FORECAST')
C/END-EXEC
