[SOLVED] html Composer (text Box variable)

Hi all,
I have a text box (Html composer) that takes a number and passes it to a procedure. When I type a number it works fine. However, when there is no number (blank field) it fails to generate the report. Here is the code I used to check for 0 or null value in the .fex

-IF ('&XFIELD' EQ '' OR 0 OR NULL) THEN GOTO XFIELD;
WHERE (FIELDA EQ '&XFIELD');
-XFIELD

Please note the Field in the DB I am verifying against is Number(7)

Please advise.

Do you get an error message?

I would code the IF statement slightly differently:

-IF &XFIELD.EXISTS EQ 0 GOTO XFIELD;
-IF &XFIELD EQ '' OR &XFIELD EQ 0 GOTO XFIELD;
WHERE (FIELDA EQ '&XFIELD');
-XFIELD

Set a default value of 0 for the variable so it will have that value if the user does not enter one.

-DEFAULT &XFIELD = 0
-IF (&XFIELD EQ 0) GOTO XFIELD ;
WHERE (FIELDA EQ &XFIELD);
-XFIELD

HINT: Always use a DEFAULT for variable which may / may not be present. Actually, why not always use a DEFAULT for a variable? It makes easy testing and HTML Composing... I do something like
-DEFAULT &MyVar = '*' ;
-SET &MyVar = IF &MyVar EQ '*' THEN This ELSE That ;
... Continue with code
However, if your variable is coming in for the composer (Launch Page) then why not pass in a FOC_NONE? Then there's no need for branching...

-DEFAULT &XFIELD=FOC_NONE;
-SET &XFIELD=IF &XFIELD EQ 0 THEN FOC_NONE ELSE &XFIELD;

TABLE FILE ZZZ
PRINT
...
WHERE FIELDA EQ &XFIELD;
END


Make sure to place the WHERE statement that checks for &XFIELD in a separate line,without mixing with other conditions. When FOC_NONE is passed, WebFOCUS Server's 'Describe' layer will remove the entire line.
