Re: passsing parameters to query/400

[Gwecnal@xxxxxxx]

In a message dated 00-01-12 01:44:14 EST, you write:

If the date is always "today" or "yesterday" or "the last 7 days" or 
something like that, you could change the query to make the selection. To do 
this, define a result field as the difference between the file date and today:

difference = days(current(date) - yourdate))

and select the records you want (difference = 1, difference < 7, whatever).  
If the date in your file is not a date data type (shame,shame) then use the 
substring and concatination operators to put it in the right form, then the 
DATE op code to turn it into a date, then do the subtraction.

difference = days(current(date) - date(substr(yourdate),1,2 || '/' || 
substr(yourdate),3,2 || '/' || substr(yourdate),5,4)

(I don't have the parentheses correct)

On the other hand, if the date needs to be user-selectable, you can't use 
this method.  HTH, Lance
