WILDCARD does not find record when field is blank

In my WHERE conditions I am entering a wildcard ($*) to pick up any value in the field. But when the field has no values, are blank, then no records are displayed.

Ex: WHERE (PGM_CODE EQ '&PGM_CD')
AND (PO_NUMBER EQ '&PO_NBR')
AND (PRIME_APPROVER_ID EQ '&PRIME');

There is always a PGM_CODE and PO_NBR but not always is there a PRIME. When the parameters are displayed I enter a value for PGM_CODE, a $* for PO_NBR and PRIME. But no records are displayed because there are records with blanks in the PRIME field.

Using the MISSING operator is not the approach because the user would not know if the field has values or not. What would be a better approach to address this issue?

G, the more modern way of filtering for all values is FOC_NONE
(there is also a FOC_ALL but i'm a little fuzzy on the distinction)
Instead of entering $*, enter the word FOC_NONE.
Sounds a bit odd, i know, but its quite nice.
See if you get what you want.
And, do please edit your profile to put your setup details in your signature.

As the default behavior when using FOC_NONE is to "internally" comment out the WHERE statement that contains it, I have found occasion that when using FOC_NONE with a compound WHERE, it ignores the whole WHERE statement if it finds a FOC_NONE. Haven't dug into it much, but it's just as easy to code them as separate WHERE statements and not worry about the issue.
Also, on a related note, I found that using 'EQ '$*'' has caused problem for fields that can be null because it excludes records with a null in the field - so it's probably best to start using the FOC_NONE.

Darin

and, as Utah says,
$* won't work if the field is /A1
The test value '$*' is longer than the field value.

Add a -SET for your last test:

-SET &CK_PRIME = IF &PRIME EQ ' ' THEN ';' ELSE
- 'AND (PRIME_APPROVER_ID EQ | '&PRIME' | ');';

then:

WHERE (PGM_CODE EQ '&PGM_CD')
AND (PO_NUMBER EQ '&PO_NBR')
&CK_PRIME

Thanks everyone, good stuff.

The FOC_NONE worked just fine. The actual code had several fields that required the same syntax and I was able to use it for all the prompts.
