Question

I want to buy Pre-owned iPhone 5 and I am asking the difference between the preowned and the refurbished . Also, I wanted to know if the preowned iPhonewill be having hardware problems or any scratches on the device

Answer 1

Also be aware that "when-create-record" may fire more often than you expect, like when:
1. the form is opened and/or the operator first navigates into the block (you likely expect it to fire here, but what if the operator simply wants to query this time?);
2. the operator navigates past the last record retrieved by a query;
3. the operator does a clear-record, clear-block or clear-form;
etc.
The "pre-insert" trigger will fire exactly once for each record at commit time. The only way it could be fired multiple times is if a database trigger or other, later form trigger fails with an error, and the operator fixes the problem and attempts the save again, then the pre-insert will fire again for each record.
