Coincidentally, I was working on a program using the following code. I was
TRACEing it and when it got to the point of creating "TEMPVIEW" I got the
INVALID DATE VALUE (2418) error.
The columns REJDATE and PRODDATE are date columns from the tables.
PRTO_TRKG_VIEW and DALY_PROD_WTS are views based on underlying tables.
The only thing that may be remotely common to this problem is that I create
the views with one or more UNION statements. There's no reason that should
be a problem.
If someone can see where I should be doing this differently I would welcome
any suggestions. Interestingly, without changing a thing, I re-TRACEd the
program and it ran fine!

It has always been my understanding that you compare DATE columns against
DATE variables. It is possible that you could get away comparing DATE
columns against TEXT variables as R:Base used to be very forgiving on this
type of thing, but it is likely that as the rules are tighten, it might not
work in the future.

Javier, Bernie, Victor, et. al.
Thanks so much to all who have responded. I really appreciate the help and
suggestions.
My bottom line question is: Which is the best practice for using defined
variables against date columns?
Is it best practice to use true date variables (which seems to make the most
sense) or should I be using the text equivalent of a date variable? What
would Wayne or Razzak recommend? Is there a preferred date format that may
be less problematic?
I frequently use the BETWEEN option in my SELECT statements. Would there be
any difference in the way R:Base interprets "BETWEEN" versus using "greater
than or equal" and "less than or equal to" syntax?
Thanks again.

I see your problem...you need to compare DATE type to DATE type; you
expression should be:
SET VAR vmaxdate DATE = ( .#date - 1)
SET VAR vmindate DATE = ( .vmaxdate - 7 )
-- VAR vmaxtext TEXT = .vmaxdate
-- VAR vmintext TEXT = .vmindate
SELECT dispdate, dfct_code, pounds FROM rej_view +
WHERE dispdate BETWEEN .vmindate AND .vmaxdate
-- (where dispdate is a date column)

Javier:
The place in my code where I get the error is when I use the variable
reference in a SELECT statement.
For example:
SET VAR vmaxdate DATE = ( .#date - 1)
--
SET VAR vmindate DATE = ( .vmaxdate - 7 )
--
SET VAR vmaxtext TEXT = .vmaxdate
--
SET VAR vmintext TEXT = .vmindate
--
SELECT dispdate, dfct_code, pounds FROM rej_view WHERE dispdate BETWEEN
.vmintext AND .vmaxtext (where dispdate is a date column)
It's something to do with how R:Base is interpreting the variables at a
particular moment in time. The same variables will be interpreted correctly
at one point in a program and will err out in another part of my program.
I am going to go through my programs and use your suggestion about using the
CTXT function. I'll see if that helps.
Thanks -- Mike

I believe that your code should work correctly; however, I prefer the
following command to convert a DATE value to TEXT:
SET VAR vmintext TEXT = (CTXT(.vmindate))
I am not sure where in your code you get the error. I would think that it
would be if you try to compare/equate variables of different type. You might
try TRACEing your code to determine where you get the error and then make
sure that your variables are properly defined and your expressions have
variables of like type.

Subject: [RBASE-L] - Invalid date value error
Good morning:
I frequently get an "Invalid date value" error in my programs. Based on
advice from the list, I typically create a date variable and then assign the
value to a text variable.
For example:
SET VAR vmindate DATE = ( .#date - 1)
--
SET VAR vmintext TEXT = .vmindate
I then use the text equivalent of the variable in my program using <column>
= .vmintext.
What is perplexing is that I can run a program and get the error message and
then IMMEDIATELY rerun the program and it will run fine with no errors. I
have confirmed the value of the variables using the SHOW VAR command. My
database gets RELOADed daily and I run R:SCOPE against to verify the
database integrity.
Why is this happening? Is there a better way to deal with date values?
I am using R:Base 6.5++ (sorry, my company hasn't given me the money yet to
upgrade to 7.1 -- drat!)
Please help before I go completely crazy!
Thanks
