While using "Call function in multi-threads" and put remove current element from resource inside the function, it will remove all resource element that has been already used in the function and not only the current element in thread.
Great thanks, will do a bit more reading. I'm not sure what advanced DB settings BAS even has for this kind of thing. TBH I will probably just create a work around and start using a schedule to run with 1 thread regularly until a condition is met. Then the DB is updated in real time and massively minimises the odds of a single row being selected by two scripts. Bit of a pain, but I can't see any options in BAS so far to implement what you're discussing! Best Regards
