Thoughts on UUID

The new function in FM12 Get(UUID) seems like a real boon, especially for those deployments that will be both desktop and idevice.

 

I am at the start of a small system, building it from scratch in FM12.

 

My thought is to use the UUID as the key field for a record, since it is my understanding that it would be absolutely, totally unique.

 

I am looking for opinions about using a calculation field for this primary key vs using an autoentered calc for the key.

 

The reason I ask is that I often use a technique for creating child records that *pushes* the creation by matching a global field in the parent [null value] with the key field in the child. This does not seem to work if the key field in child is a calculation; it does if the key field is an auto-entered calc.

 

Your opinions are appreciated.

 

Michele
