Re: FW: reset all sequences

Hi,

You could generate a common script to reset all the sequence using:

select 'alter sequence '||relname||' restart with 1 ;' from pg_class where relkind='S' ;

Then execute the output of that script to restart all the sequences from 1. Does that solve your problem?

How can I reset the sequence to “1”
If I use the following statement
Select setval('mytable_id_seq',1);
I put the last value as 1
So when I insert a new row the value will be “2” and not “1” as it should be
I cannot put Select setval('mytable_id_seq',0);

What should I do ??!!

Thx
Pascal

You can do something like:
select * from pg_class where relkind = 'S';
The relname column will give you the sequence name.
