Question

我有一些代码可以将数据输入到列表中，如何将列表中的数据导入数据库中？

import psycopg2
import random
import string
import time

conn = psycopg2.connect(host="localhost",database="postgres", user="postgres", password="potatona1")
cursor = conn.cursor()

FullChar = 'CEFLMPRTVWXYK0123456789#'
total = 4
count = 10
count = int(count)


for i in range(1000):
    for x in range(total): 
        unique_code = ''.join(random.sample(FullChar, count - 1)) + '#'
        unique_code = ''.join(random.sample(unique_code, len(unique_code)))

        list(unique_code)

        postgres_insert_query = """ INSERT INTO employees (id_employee, name) VALUES (%s,%s)"""
        record_to_insert = (1, unique_code)
        cursor.execute(postgres_insert_query, record_to_insert)
        conn.commit()
        count = cursor.rowcount
        print (count, "Record inserted successfully into mobile table")

我想使用python将1000数据导入Postgresql。

我只是尝试这种方法，它有效 conn = psycopg2.connect(host="192.168.13.10",database="postgres", port="5432", user="postgres", password="potatona1") cursor = conn.cursor()

FullChar = 'CEFLMPRTVWXYK0123456789'
total = 1000
count = 10
count = int(count)
entries = []
bcd = ""
flg = ""
rll = ""

def inputDatabase(data): postgres_insert_query = """INSERT INTO unique_code(unique_code, barcode, flag, roll) VALUES (%s,%s,%s,%s)""" cursor.executemany(postgres_insert_query, data) conn.commit()

for i in range(5):
    for x in range(total):    # banyaknya code yang di print
        unique_code = ''.join(random.sample(FullChar, count - 1))
        unique_code = ''.join(random.sample(unique_code, len(unique_code)))

        entry = (unique_code, bcd, flg, rll)
        entries.append(entry)

    inputDatabase(entries)
    print(i)

count = cursor.rowcount
print (count, "Record inserted successfully into mobile table")
