>>>>>>Hi,

>>>>>>I have a routine where the application gets (via SQL select) records into one cursor from one table, then into another cursor from another table, and then again into the 3rd one. For each cursor I use value of SYS(2015). Since the SQL Select time from one cursor to another may take a second or two or could be less than a second. Can I rely that each value of SYS(2015) is unique if it is called within less than a second?

>>But could the following scenario happen? Say, the application creates a cursor named "MyCursor." Isn't it true that the temp folder of the PC now has a file MyCursor? Then for some reason, the application locks up and does not have a chance to close all cursors. So when user starts the application again ant it attempts to create a cursor "MyCursor" wouldn't you get a message that the file already exists?

I got it. Thank you for clarifying.
