Re: filtering records between 2 dates -- RPG400-L

Interesting, Peter - the date() function is very forgiving in this case.

Now I have to ask, should the OP wrap the 2 date values with a DATE function, or should the OP use the syntax as Joe presented it? I prefer the latter, esp. because function calls in WHERE clauses CAN result in a full table scan - not likely here, where the function is run against a literal, though.

Vern

Yes, ORDDAT is a date. Format does not matter except for display purposes.

01/01/1960 is not a date. Try this:

select 01/01/1960 from sysibm/sysdummy1

Now try this:

select '01/01/1960' from sysibm/sysdummy1

And finally, try this:

select DATE('01/01/1960') from sysibm/sysdummy1

Look at the headings in each case.

The 1st one thinks 01/01/1960 is some sort of number.

The 2nd one thinks '01/01/1960' is just a literal constant.

The 3rd one recognizes that it's a date.

I always try to use ISO dates:

where ORDDAT between '1960-01-01' and '2000-12-31'

my sql statement is like below:-

SELECT * FROM p2
WHERE ORDDAT BETWEEN 01/01/1960 AND 31/12/2000

Comparison operator BETWEEN operands not compatible.

File P2 is having ORDDAT field as a date field and is defined using 'L'
data type.

So I want to filter records between some specific date range but unable
to

do so because of the mentioned error.
So need guidance how could i remove this error to get desired results?

Thanks much..
