So I have been trying to create a database using a .sql file. The first time we do it, it works perfectly, but it has to work everytime.If I create a database in postgres myself, the script works perfectly, but if I haven't made the database manually, the script says: psql:script_name:40: ERROR: database dbname does not exist.
This is the code:
--dit is een psql die eerst de database project dropt, vervolgens--maakt hij opnieuw de database project aan.--De de tabellen die hierbij worden gemaakt zijn:--Pathway_C1, Eiwit_C1, Gen_C1, Gen_Go_C1, Go_termen_c1 en Gen_kegg_C1---- PostgreSQL database dump---- Dumped from database version 9.5.14-- Dumped by pg_dump version 9.5.14SET statement_timeout = 0;SET lock_timeout = 0;SET client_encoding = 'UTF8';SET standard_conforming_strings = on;SELECT pg_catalog.set_config('search_path', '', false);SET check_function_bodies = false;SET client_min_messages = warning;SET row_security = off;---- Name: plpgsql; Type: EXTENSION; Schema: -; Owner: ---CREATE EXTENSION IF NOT EXISTS plpgsql WITH SCHEMA pg_catalog;---- Name: EXTENSION plpgsql; Type: COMMENT; Schema: -; Owner: ---COMMENT ON EXTENSION plpgsql IS 'PL/pgSQL procedural language';SET default_tablespace = '';SET default_with_oids = false;DROP DATABASE project;CREATE DATABASE project; \c projectCREATE TABLE Pathway_C1 ( Kegg_co CHAR(8) NOT NULL, PRIMARY KEY (Kegg_co));CREATE TABLE Go_termen_C1 ( Go_nummer CHAR(10) NOT NULL, Go_functie VARCHAR(1000) NOT NULL, PRIMARY KEY (Go_nummer));CREATE TABLE Gen_C1 ( Gen_ID INTEGER NOT NULL, Gen_naam VARCHAR(50) NOT NULL, PRIMARY KEY (Gen_ID));CREATE TABLE Eiwit_C1 ( Eiwit_ID CHAR(12) NOT NULL, Gen_ID INTEGER NOT NULL, Eiwit_naam VARCHAR(500) NOT NULL, Eiwit_Lengte INTEGER NOT NULL, PRIMARY KEY (Eiwit_ID), FOREIGN KEY (Gen_ID) REFERENCES Gen_C1(Gen_ID));CREATE TABLE Gen_Kegg_C1 ( Gen_ID INTEGER NOT NULL, Kegg_co CHAR(8) NOT NULL, PRIMARY KEY (Gen_ID, Kegg_co), FOREIGN KEY (Kegg_co) REFERENCES Pathway_C1(Kegg_co), FOREIGN KEY (Gen_ID) REFERENCES Gen_C1(Gen_ID));CREATE TABLE Gen_Go_C1 ( Gen_ID INTEGER NOT NULL, Go_nummer CHAR(10) NOT NULL, PRIMARY KEY (Gen_ID, Go_nummer), FOREIGN KEY (Gen_ID) REFERENCES Gen_C1(Gen_ID), FOREIGN KEY (Go_nummer) REFERENCES Go_termen_C1(Go_nummer));GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO username; ---- Name: SCHEMA public; Type: ACL; Schema: -; Owner: ---REVOKE ALL ON SCHEMA public FROM PUBLIC;REVOKE ALL ON SCHEMA public FROM postgres;GRANT ALL ON SCHEMA public TO postgres;GRANT ALL ON SCHEMA public TO PUBLIC;---- PostgreSQL database dump complete--enter code herePlease don't pay attention to the comments we put in the script, they are not really important.
