postgresql: Fast way to update the latest inserted row
- by Anonymous
What is the best way to modify the latest added row without using a temporary table.
E.g. the table structure is
id | text | date
My current approach would be an insert with the postgresql specific command "returning id" so that I can update the table afterwards with
update myTable set date='2013-11-11' where id = lastRow
However I have the feeling that postgresql is not simply using the last row but is iterating through millions of entries until "id = lastRow" is found. How can i directly access the last added row?
