Quick CEILING question

[Knum]

De query <cfquery name='UpdateRating' datasource='#dSn#'> update tableName
set columnA = CEILING(columnA - 1) , columnB = CEILING(columnB + 1)
where id = 89 </cfquery> I can't\don't seem to use\ing CEILING correctly. I
want to try and use the Transact SQL numerical function of CEILING to keep
columnA from ever going negitave. BTW, yes I suck and am using MSAccess as my
DS. I can ROUND but I can't CEILING... Am I just syntaxually-tarded.

Update: I am still looking and I think that CEILING it not the right tack for
me to turn to... I am only dealing with the number 1. That is adding it or
subtracting with the number one. So I came up with a dim-witted, dull,
feebleminded, half-witted, imbecile, moronic, simpleminded, unenlightened,
reactionary, obtuse, stupid, thickheaded, unenlightened, uninformed,
underdeveloped, undeveloped and unprogressive way of doing it. <cftransaction>
<cfquery name='UpdateTable' datasource='#dNs'> update tableName set ColumnA =
ColumnA - 1 where id = 89 and ColumnA <> 0 </cfquery> <cfquery
name='UpdateRating' datasource='ourgardens'> update Books set ColumnA =
ColumnA + 1 where id = 89 and ColumnA <> 32767 </cfquery> </cftransaction>
Still doesn't solve the root problem of not allowing the column to fall into
negitave numbers. Please help... I can't find Jack or his brother Dit-a-Lee on
the net about how to keep it positive.
