Hi,
When I:
Begin a transaction
DELETE from <table> where id (PK) = <somevalue>
INSERT INTO <table> VALUES (<values - same PK>)
...
...
...
COMMIT
I get
insert into "itinerary" ("dk", "locator") values ($1, $2) - duplicate
key value violates unique constraint "itinerary_pkey"
<table> = itinerary?
What fields is unique constraint "itinerary_pkey" actually pointing at?
There should be more to the error message. Can you provide the complete
message?
Do I need some particular kind of settings on my transaction to be able
to delete and insert afresh in the same transaction?
In case it is relevant - the first delete will lead to cascaded deletes
on children.
Alternatively I wonder if I change the PK column value to
"<somevalue>-FORDELETION" will I be free to insert under the same
original PK value in the same transaction, then delete the FORDELETE
item just before committing or will I hit the same issue?
Thanks,
Andrew
