尝试将数据插入 PostgreSQL 数据库。
Python 代码:
myFields = ((DOT_Number,),(Entity_Type,),(Operating_Status,),(Legal_Name,),
(Phone,),(Address,)
)
query = """ INSERT INTO saferdb_question( DOT_Number, Entity_Type, Operating_Status, Legal_Name, Phone, Address)VALUES ( %s, %s, %s, %s, %s, %s);"""
cur.execute( query, myFields)
出现错误:
Traceback (most recent call last):
File "scraper.py", line 189, in <module>
cur.execute( query, myFields)
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/psycopg2/extras.py", line 144, in execute
return super(DictCursor, self).execute(query, vars)
psycopg2.ProgrammingError: column "dot_number" of relation "saferdb_question" does not exist
LINE 1: INSERT INTO saferdb_question( DOT_Number, Entity_Type, Oper...
来自 PostgreSQL 的创建表的 SQL:
CREATE TABLE public.saferdb_question
(
id integer NOT NULL DEFAULT nextval('saferdb_question_id_seq'::regclass),
"DOT_Number" character varying(10) COLLATE pg_catalog."default" NOT NULL,
...
"Phone" character varying(15) COLLATE pg_catalog."default" NOT NULL,
"Address" character varying(200) COLLATE pg_catalog."default" NOT NULL,
)
WITH (
OIDS = FALSE
)
TABLESPACE pg_default;
ALTER TABLE public.saferdb_question
OWNER to postgres;
最佳答案
终于解决了这个问题。 这些列必须用引号引起来。这是最终的查询字符串:
query = """ INSERT INTO public.saferdb_question( "DOT_Number", "Entity_Type", "Operating_Status", "Legal_Name", "Phone", "Address")VALUES ( %s, %s, %s, %s, %s, %s);"""
