In Profiler, this is given for clientProcessID: The process id of the application calling sql server. Does this mean, that a particular application, say excel would have the same clientprocessid at that time or is it different?
It's the processID that you see if you open task manager on a client machine. Different every time the application runs.
I could not locate the correct page which explains all the fields.
The link I gave you lists each event that profiler can trace. Each event then lists the columns that event populates and what the values they'll have. I don't think there's a master-list of columns because for some of them their values have different meanings for different events.
