I have this table:
idsession name num_objects
1 James 1
2 Laure 2
3 Daniel 3
I want to update the table with a new record
2 Laure 4
How can I delete a old record and update a new record with a pl/pgsql function with parameter idsession?
Example: If idsession is in the table then delete old record and update the new. If idsession is not in the table only update the new record.
