Re: Using CFLock around a query
Yes and no. In one case, I found concurrent queries and I also found 2 sessions hitting the same table. >Did you find any concurrent queries? >For a deadlock you need at least two SQL sessions hitting the same object. > > > >It is not unlikely this can deadlock, but to be certain we need to see >the actual SQL. This is the SQL Update DMSdata Set PolicyNumber = '345627' where ID = '94631' The strange thing is also, the second case, which was when we got the error, on a different day, on a different table, but we couldn't find 2 sessions that hit the table at the same time. The query is similar, but the tablename is different and there are a lot more columns being updated.

RE: using cflock with scope vs name
In short, name locking provides more flexibility and granularity but also requires better planning on lock usage. My personal best practice is to always use scope locking for memory variables. However that doesn't mean there is no place for name based locks. For example, when I modify a file using cffile, I try to wrap the tag in a lock like this... Then I use a readonly lock whenever I read from the file. -Original Message- From: David Schmidt [mailto:[EMAIL PROTECTED]] Sent: Tuesday, May 14, 2002 10:42 AM To: CF-Talk Subject: using cflock with scope vs name Is there a benefit to use the name= attribute rather than the scope= attribute in a cflock statement.

If you're locking memory variables (Session, Application, Server) on CF 4.5.x or 5, I'd recommend using the SCOPE attribute. If you're locking something else, or you're using CF 4.0.x, use the NAME attribute.

Allaire has changed their recommendation since CF 4.5 came out, and their recommendation has certainly been a moving target. The current recommendation is to use it for all memory variables, and to use the SCOPE attribute when you lock memory variables. I didn't read the entire thread, so you've probably already stated that, but it's important enough to reiterate.

session.sessionid is a value which is set by the CF server, not by the user, and is based on the CFID and CFToken cookies.
