尝试将 python 日期时间插入 SQL DATE

Question

尝试将 python 日期时间插入 SQL DATE，但不断出现错误，提示 OperationalError: near "02": syntax error

import  sqlite3
conn=sqlite3.connect("Date_time3.db")
print("Database Opened successfully")
conn.execute("""
CREATE TABLE ADMIN(
EXPIRE DATETIME PRIMARY KEY
)
""")

这是我的数据库^

import datetime 
import pytz
import  sqlite3

today = datetime.datetime.now()
date_time = today.strftime("%m/%d/%Y, %H:%M:%S")

conn=sqlite3.connect("Date_time3.db")
print("Database Opened successfully")

conn.execute("INSERT INTO ADMIN(EXPIRE) VALUES " +date_time);



conn.commit()
print ("Records inserted successfully")
conn.close()
"""
###Output###
#Database Opened successfully
#Records inserted successfully
#"""
print ("Table ADMIN created successfully")
"""
####Output###
Database Opened successfully
Table ADMIN created successfully
"""

Answer 1

改变这个：

conn.execute("INSERT INTO ADMIN(EXPIRE) VALUES " +date_time);

到

conn.execute('INSERT INTO ADMIN(EXPIRE) VALUES (?)', [date_time]);

由于您是运行 SQL 命令，它们的工作方式与 Python 不同。所以你不能使用 + 运算符。您需要使用 (?)

等占位符
