Are there any wildcard characters allowed in a DECODE in WebFOCUS? I've seen dollar signs used as wildcard characters in WHERE clauses, but someone I work with discovered some old code that is using a dollar sign in a DECODE. We just upgraded to 7.6 and when we also discover problems like this, it's easy to conclude that it is a problem with the new version of WebFOCUS. I argue that this never worked because I don't think DECODEs can use wildcards. Can someone definitively tell me whether DECODEs can contain wildcard characters? Thanks for your time!

In my nn years of experience, I've never used a wild-card character in a DECODE.

I've never heard of wild card characters in decode, but seeing the code would be nice. Is it on an ELSE in the decode?

We have found when upgrading...strange things that should not have worked - did in older version...and then suddenly they did not because of "tightening the code".

Using DECODE will only allow you to compare literal values and it will only return a literal value. There is no support for wildcards within a decode. All characters are treated as they are specified. The only operator used internally with DECODE is the EQ operator. If the value offered is not in the decode list, you'll get the values specified by the ELSE clause in the DECODE.
That's all folks.

Thanks GamP for explaining what is happening internally. For those who wanted a code example, I'll give you a generic sample, however I was more interested in simply knowing whether or not DECODE allowed wildcard characters.

For example, wanting to flag all rows containing a CUSIP beginning with '918'...

DEFINE
FILE THIS
FLAG/A1=DECODE CUSIP (
'918$$$$$$' 'Y'
ELSE 'N');
END

To my knowledge, and I have been using FOCUS and WebFOCUS for over 20 years, unless your CUSIP exactly equaled '918$$$$$$', FLAG would always be 'N'.

One correct syntax would be:
FLAG/A1=IF EDIT(CUSIP,'999') EQ '918' THEN 'Y' ELSE 'N';

If you are using FLAG in a where statement eliminate this are replace it with
WHERE EDIT(CUSIP,'999') EQ (OR NE) '918'
rather than
WHERE FLAG EQ 'Y' (OR 'N')
