Scripted delete record best practice

[Drew Sanderson]

What steps do you take when scripting a delete record both in general and specifically when doing a go to related record?

Making sure that you have the record(s) that you definitely want to delete as the found set. You should make sure that you properly error trap, especially when using GTRR as if there are none, you could be deleting out parent records.

What error trapping precautions do you take? Check the parent table? Check the found count?

First I check to see if there is a related record.

If [ IsEmpty ( Child::ChildID ) ]

Set Error Capture [On]

Go to Related Records [show related only]

If [ Get (LastError) ]

Show Custom Dialog ["Error"]

Else

do something

End If

This is okay if you are using GTRR for the current parent record.

However, if you are trying to match on the found set, things are a little different for capturing the error code.

If none of the parent records have matching children records, then it should result in a 401 error.

If the first parent record does not have related records but some of the other parent records do, then it will result in a 101 error.
