我尝试在我的架构上从文件创建表,但是我收到错误消息。在公共模式上创建的用户表已成功,但我在test1模式上创建的其他表是错误的。我不知道为什么,请帮帮我。 感谢提前。
CREATE SCHEMA test1
--Create sequence
CREATE SEQUENCE test1.table_id_seq START 1;
--Create function to auto generate ID
CREATE OR REPLACE FUNCTION test1.next_id(OUT result bigint) AS $$
DECLARE
our_epoch bigint := 1314220021721;
seq_id bigint;
now_millis bigint;
shard_id int := 1;
BEGIN
SELECT nextval('test1.table_id_seq') % 1024 INTO seq_id;
SELECT FLOOR(EXTRACT(EPOCH FROM clock_timestamp()) * 1000) INTO now_millis;
result := (now_millis - our_epoch) << 23;
result := result | (shard_id << 10);
result := result | (seq_id);
END;
$$ LANGUAGE PLPGSQL;
--Talbe ----users----
CREATE TABLE users

id bigserial NOT NULL PRIMARY KEY,
username varchar(30) NOT NULL UNIQUE,

--Table ----comments----

--Table ----likes----

--Table ----follows----
CREATE TABLE test1.follows

CREATE TABLE teset1.feeds

那么,向我们展示您获得的错误以及您尝试修复错误的内容对您有所帮助。但是,您发布的SQL存在一些明显的问题:
TL; DR 创建此转储文件的人并未密切关注。
解决了上述所有问题后,我设法加载了SQL。
