如何在 Django 中使用 sql 文件创建 postgressql 数据库？请指导我一步一步。我有 sql 如下

Question

这里是 sql 我想转换成 postgresql 数据库的文件代码

CREATE TABLE banks (
        name character varying(49),
        id bigint NOT NULL
    );

--
-- Name: branches; Type: TABLE; Schema: public; Owner: siva; Tablespace: 
--

CREATE TABLE branches (
    ifsc character varying(11) NOT NULL,
    bank_id bigint,
    branch character varying(74),
    address character varying(195),
    city character varying(50),
    district character varying(50),
    state character varying(26)
);


--
-- Name: bank_branches; Type: VIEW; Schema: public; Owner: siva
--

CREATE VIEW bank_branches AS
 SELECT branches.ifsc,
    branches.bank_id,
    branches.branch,
    branches.address,
    branches.city,
    branches.district,
    branches.state,
    banks.name AS bank_name
   FROM (branches
     JOIN banks ON ((branches.bank_id = banks.id)));

然后有 120k 行输入使用标准输入

COPY banks (name, id) FROM stdin;
COPY branches (ifsc, bank_id, branch, address, city, district, state) FROM stdin;

我用的是django3.2,psycopg2.8,postgrsql13,windows10

Answer 1

ERROR: character with byte sequence 0x90 in encoding "WIN1252" has no equivalent in encoding "UTF8"

对于这个错误，我将文件转换为 ANSI 并在记事本中删除了所有在 UTF8 中不可见的 ANSI 字符。

然后运行按照来自 psql 的命令 shell

psql -h localhost -d databasename -U username -f "c://path_to_file.sql"
