if during deletion, I choose to set the uniqueKey to recNo delete;

would I reuse the uniqukey instantly on my next creation.

would it cause any problem?

People have reused deleted record numbers, you should be aware of this from the plenty of threads about it, just search . Is not clear that reusing deleted record numbers would not cause a problem when implemented correctly?

I reused deleted record numbers, did not have any issue with it. But if you don't feel comfortable with it, just don't do it. It's not a must requirement, so you are not required too.

Howdy, Ixus!

I too chose to reuse deleted entries.

Champ, I don't get... what is this uniqueKey that you talk about?

You should try leave coding to your .java files and use correctly structured English when writing in forums - make an effort . As the saying goes "you get what you give" - if you put in very little effort with writing your posts then you shouldn't expect people to put much effort into reading or replying to them.

Similarly with problems you are trying to solve, if you don't put much effort into solving them yourself then you shouldn't expect others to either.

I completely agree, couldn't have said it better (also because my English is not that good ) It totally deserves +1
