There was a problem hiding this comment.
it seems these can be used in the SELECT statement as well and there are others like dateOnly()
Should we be optimising them all?

We were using them when there are projections (like findNameById and similar) and now also for comparison and ordering.
I tried dateOnly() and got the exception
ORA-40597: JSON path expression syntax error ('$.birthDate.dateOnly()')
JZN-00241: Message 241 not found; No message file for product=XDK, facility=JZN Message 200 not found; No message file for product=XDK, facility=JZN
So I wouldn't like to break something and will use .date() like it was before.
