Re: [firebird-support] Issues migrating from FB 1.5 to 2.5

Hi Karol, I think you are right on, I found this which is what I suspect is 
throwing the error in 2.5 (but not so in 1.5). I might have to go back to my 
old box running 1.5.  Do you know if it is possible to convert and downgrade a 
2.5 *.fdb file to a 1.5 version ?
 Multiple Hits to Same Column Now Illegal
 It is no longer allowed to make multiple “hits” on the same column in an 
INSERT or UPDATE statement. Thus, a statement like
   INSERT INTO T(A, B, A) ...
      or
   UPDATE T SET A = x, B = y, A = z
      will be rejected in Firebird 2.n, even though it was tolerated in 
InterBase and previous Firebird versions.
