Hello,
you need to use execute command
i.e.
execute 'alter table ........ ' || newcol || ';'

Subject: using vars in ddl in procedure call
Hi:
v9.0.1 on linux.
Trying (failing) a test to see if I can run ddl in a procedure where elements of the ddl are vars. Consider...
create or replace function newcol (text) returns integer as $$
declare
newcol alias for $1;
begin
alter table target add column newcol text;
return(0);
end;
$$ language plpgsql;
This successfully adds a column called "newcol" instead of what I passed it as an arg.
Any suggestions on how to make this work?
Thanks !
