createUID() uses ActionScript's Math.random() to generate 24 of the 32 bytes of the UID; the other 8 are determined from the current date-time. The chance that these UIDs wouldn't be good enough for database keys is very small. But just in case, couldn't you simply call createUID() again if the database errored because a new row didn't have a unique key? - Gordon ________________________________

This statement from the Flex Live docs on adobe.com states: "This UID will not be truly globally unique; but it is the best we can do without player support for UID generation." Maybe i'm reading that wrong... but i'm not getting the sense that I can guarantee these numbers to be unique across the board and be used to uniquely identify rows in a database... either as the primary key itself but most likely to determine the PK based on the rowGUID column. --Scott --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Gordon Smith" <[EMAIL PROTECTED]> wrote: > > What are your concerns regarding createUID()? > > - Gordon > > ________________________________ > > From: [email protected] <mailto:flexcoders%40yahoogroups.com> [mailto:[email protected] <mailto:flexcoders%40yahoogroups.com> ] On > Behalf Of scott_flex > Sent: Monday, March 05, 2007 4:57 PM > To: [email protected] <mailto:flexcoders%40yahoogroups.com> > Subject: [flexcoders] Not able to generate GUID > > > > > Is there no function or object to generate a GUID, a true globally > unique identifier? > > the createUID is not what i'm looking for, just figured generating a > GUID would be something pretty basic. >
