Scott Suppose I have 2 queries in cftransaction 1- inserts into database 2 reads from database Then <cftransaction action="commit">
is it only after the commit i will be able to see the values in the database? my 1st insert is " load data infile" somehow i cant see my results in database during the process and it is able to get results out of second query that means there is something in DB, but why can't i see it? when i do load data infile in a cftransaction i cant see results in DB Do you have any suggestion DG >Tom, > >The statement about, You should only use cftransaction tag to make sequence >of SQL statements into one atomic unit. > >Is Correct. > >Your Statement about, You should never have anything inside your >cftransaction block that is not SQL related especially if its going to take >a long time (i.e. more than few ms). > >Is not Correct, in the instance of objects and dao's it is the only way to >achieve a transaction for your queries, for example. > ><cftransaction> > <cfset copyRecord = object.Load(id=100) /> > <cfset newObject = Object.CreateRecord() /> > <cfset newObject.setItem(copyRecord.getItem()) /> > <cfset fileObject.SaveImage(form.Somefilename) /> > <cfset newObject.Save(false) /> ></cftransaction> > >Now to role this back for files, you will need to wrap the entire thing in a >cftry block, so that you can delete or whatever you need to do with the >maintenance of the file. > > > >Andrew Scott >Senior Coldfusion Developer >Aegeon Pty.
