Dear readers,

When i execute the folowing SQL query, i get the error colomn "WTG"not found.

SELECT detail.avr_ari,;
iif(Detail.avr_wtg=.t.,'J','N') as WTG;
FROM general!detail;
WHERE WTG='J'

Is this an impossible kind of query, to include an expressionalias in the WHERE Clause ?

Any idea's how to solve this ?
