使用Python将CSV数据导入到PostgreSQL

Question

我正在尝试使用Python将我的CSV数据导入到PostgreSQL中。当我运行代码时，它在(User)附近显示一个错误。请有人提供帮助。我是编程新手，请原谅我的愚蠢。

import psycopg2
import csv

csv_data = csv.reader(file('SampleData2.csv'))

database = psycopg2.connect (database = "***", user="***", password="***", host="localhost", port="5432")

cursor = database.cursor()
delete = """Drop table if exists Real.SampleDataTwo"""
print (delete)

mydata = cursor.execute(delete)

cursor.execute("""Create Table Real.SampleDataTwo
                (User varchar(55),
                LastUpdate timestamp,
                Week date,
                Builder varchar(55),
                Traffic integer
                );""")

print "Table created successfully"

for row in csv_data:

    cursor.execute("INSERT INTO Real.SampleDataTwo (User, LastUpdate, Week, Builder, Traffic)"\
                "VALUES (%s,%s,%s,%s,%s)",
               row)


cursor.close()
database.commit()
database.close()

print "CSV data imported"

它显示的错误是：

Drop table if exists Real.SampleDataTwo

Traceback (most recent call last):
  File "C:/Users/Programming/Data.py", line 20, in <module>
);""")
ProgrammingError: syntax error at or near "User"
LINE 2:                 (User varchar(55),
                         ^

我认为您缺少id参数：id INT PRIMARY KEY NOT NULL， - Jean-François Fabre

Answer 1

我认为user不能用作列名。请参见https://www.postgresql.org/docs/current/static/sql-keywords-appendix.html#KEYWORDS-TABLE

谢谢MKJ，你说得完全正确。用户不能用作列名。 - Jacob_Cortese

Answer 2

尝试将 User 更改为其他内容，看看问题是否得到解决。如果没有，请尝试运行 PostgreSQL Python 指南中提供的示例：http://www.postgresqltutorial.com/postgresql-python/create-tables/。
