hy,

Before the last modification (or another!!! ), I could write under
IBOQuery :

SELECT (SUM(xxxx) - SUM(yyyy)) As MySum From table


Now, I can just write that (without the brackets) :


SELECT SUM(xxxx) - SUM(yyyy) As MySum Form Table

if not I obtain the following error message :

ISC ERROR CODE:335544569
...
invalid column reference

but under IBCONSOLE it goes very well.

Is this normal?

I use :
Delphi 4 C/S
IBO 4 Fp
