Обсуждение: update table sequence

All,

Is there a way I can set the sequence of a table equal to highest row
ID?
For example something like:
select setval('mytable_myrowid_seq',select max(myrowid) from mytable);

I read the documentation but could not find anything relevant.

Thanks in advance,

Egbert.

So close!

select setval('mytable_myrowid_seq',max(myrowid)) from mytable;

That should work if you put in the required parentheses around the
sub-select:

select setval('mytable_myrowid_seq', (select max(myrowid) from mytable));
