Thread: create databases with plpgsql
a novice has the following challenge (problem): I would like to create a certain number of new databases named stud01, stud02...to stud25 with a plpgsql-script. But I have difficulties to create a new database with a script. I saw a lot of different scripts in the manuals to create tables, but no new db. Generally, is it possible at all? Do you may have any suggestions, workarounds, ideas? any help will be appreciated... I tried the these simple script without any loop, unfortunately without success: create or replace function createDB(text) returns text as ' DECLARE DBname ALIAS FOR $1; sqlquery text; result text; BEGIN sqlquery := ''CREATE DATABASE %'', DBname; EXECUTE( sqlquery ); RETURN DBname END; ' language 'plpgsql'; Thank you for your help sirius
As I can now create database is none transactional statment. But function performed only in transaction. So not.
