Topic: Search ora-01427 in the big request
There is a big request, some screens.
On it the pair of tens inline select which return unique record is scattered.
All is good while integrity of the data as it should be.
But if somewhere there is a violation (for example, the periods start to be intersected), one of breaks with ora-01427.
However, the Oracle does not write which, and it is necessary to search pens for an error further.
Can eat any method to simplify search?
