Re: AW: SQL Date Range Problem with Between

Thank you, Doug.

You helped me to clear my brain cell clog with the concat :-) Discovery is the mission !

I want to share the final result, which is nice and clean.

Select sum(SALES)
       From DaySALES
      WHERE CPY = 22 and STR = 1234 AND
       CALY || DIGITS(CALM) || DIGITS(CALD)
       BETWEEN '20090714' AND '20090810';

I am using host values for the BETWEEN :FrmDate And :Todate and in cpy and str,in my actual code.

Performance : Statement ran successfully   (31 ms) - via iseries navigator

Greatly Appreciate all the nice people, who share their skills to educate others.

where concat(caly,concat(calm,cald))
between '20090714' and '20090810'

The Concatenation below works but the results are bad ..
Select sum(SALES)
From DaySales
WHERE CPY = 22 and SDSTR = 1234 AND
DIGITS(2009) CONCAT'-' CONCAT DIGITS (07) CONCAT'-'
CONCAT DIGITS(15) BETWEEN '2009-07-14' AND '2009-08-10';

I tried:
Select sum(SALES)
From DaySales WHERE CPY = 22 and SDSTR = 1234 AND
DIGITS(2009) CONCAT DIGITS (07) CONCAT DIGITS(15)
BETWEEN '20090714' AND '20090810';

Off by Ml.s

Suggesting that "results are bad" and "off by Ml.s" is not
helpful to those who might choose to assist.

The DIGITS() function will not automatically cast to a character
string matching the length of the numeric literal. The numeric
field or literal will need to have exactly two-digits in precision,
or must be CAST as such [before casting to its DIGITS character
string form]. The literals will be treated as integer, which have
a precision of ten. Per that error, the latter requests the
equivalent of:
"AND '000000200900000000070000000015' BETWEEN '20090714'..."

Multiplication below, Returns Zeo (.)

Select sum(SALES)
From DaySales WHERE SDCPY = 88 and SDSTR = 1234 AND
((2009*10000) + (07*100) + 15) BETWEEN '20090714' AND

'20090810';

<<SNIP>>

Similar to the prior poor explanation of results, what does
"returns zeo (.)" mean? Perhaps "zero records"? Seems odd, since
even though the expression is numeric and the comparison values are
character strings, the implicit cast of either should give the
results just as if all were instead, proper DATE data type values.
