Hi

Hi,

I tried this code (to be inserted within a larger psql script)

do $_$
declare
        next int;
begin
        select max(id) + 1 into next from items;
        execute 'create temp sequence tmp_ids start $1' using next;

the parameter can be used only with statements with execution plan (DDL has not execution plan).

you should to use execute format('create temp sequence tmp_ids start %s", next);

Regards

Pavel Stehule
 
end
$_$ language plpgsql;

but that reports a syntax error near $1.
What is the proper way of doing that?

Best regards
Wolfgang Hamann
