Python3实现连接SQLite数据库的方法

import sqlite3

db = r"D:\pyWork\test.db"  #pyWork目录下test.db数据库文件
drp_tb_sql = "drop table if exists staff"
crt_tb_sql = """
create table if not exists staff(
  id integer primary key autoincrement unique not null,
  name varchar(100),
  city varchar(100)
);
"""

#连接数据库
con = sqlite3.connect(db)
cur = con.cursor()

#创建表staff
cur.execute(drp_tb_sql)
cur.execute(crt_tb_sql)

#插入记录
insert_sql = "insert into staff (name,city) values ("  #"select * from staff"
cur.execute(select_sql)

#返回一个list，list中的对象类型为tuple（元组）
date_set = cur.fetchall()
for row in date_set:
  print(row)

cur.close()
con.close()
