Thanks. But to do the UPDATE i have to write each column name (for recrd 4) and with its column name (for record 2) which is quite alot to write :P

UPDATE MOD48_00_2007 SET te_cognome= te_cognome, te_paternita= te_paternita WHERE N_GEN= 9

so it will be like that? But i have to set each column name = to the column name.
And i have to do it for echt field? isn't there any other way..
"I hate writting :P"

And Andrew can explain a bit the setval()

Thanks

At a surtain point i need to replace a record with another

For example i have inserted 4 records. (1, 2 ,  3 , 4) I need to
replace all the values from the record 4 to the record 2 but
keeping the n_gen serial key. And then delete the record 4. So that
the next record i insert will take the n_gen 4

If I understand you correclty, you can do an UPDATE to record 4 to
record 2, then do a setval() on the sequence.  The setval() is
tricky, though, because you have the problem that other connections
could be using it.  I'd lock the table in question while you did all
this.
