Hi,
I'm trying to create a new database by using a template database. But it is

Hi!
In other RDBMS I found a way to make dynamic statements.
I can use variables, or concat the SQL segments, and execute it all.
:tablename = call CreateTempTable;
insert into :tablename
drop table :tablename
or (FireBird like cursor handling):
sql = select * from || :tablename ||

How do I create cursor or for select in PGSQL with dynamic way?
For example

Just to make sure, you're asking for the logical AND, not the bitwise
