使用变量的 Python SQL 查询？

Question

如果这看起来太简单了，但刚刚开始编码并且似乎无法弄清楚问题是什么，请道歉。 我已经用用户输入的变量替换了硬编码值，并且数据正在保存到数据库中，但我似乎无法将其显示出来。 我的 cur.execute 选择行不正确吗？

import sqlite3
conn = sqlite3.connect("OS_Employee.db")

with conn:
cur = conn.cursor()
try:
    ID = input("Please enter your Employee ID: ")
    FirstName = input("Please enter your First Name: ")
    LastName= input("Please enter your Last Name: ")
    Email = input("Please enter your Employee Email: ")
    Password = input("Please enter your Desired Password: ")

    cur.execute ("""INSERT INTO Employee VALUES (?, ?, ?, ?, ?)""",
                 (ID, FirstName, LastName, Email, Password))

    cur.execute("SELECT EmployeeID FROM Employee WHERE (EmployeeID = ?", (ID, ))

    results = cur.fetchall()
    print(results)
except:
        print("Connection Failed")enter code here

如果缩进看起来很奇怪，它只是在 stackoverflow 上，因为 idk 如何让它正确粘贴，实际代码中没有缩进错误。 谢谢！

Answer 1

尝试替换您的行：

cur.execute("SELECT EmployeeID FROM Employee WHERE (EmployeeID = ?", (ID, ))

与：

cur.execute("SELECT EmployeeID FROM Employee WHERE EmployeeID = ?", (ID, ))

括号似乎不匹配。

尝试这个：

    cur.execute ("INSERT INTO Employee VALUES ({}, {}, {}, {}, {})".format(ID, FirstName, LastName, Email, Password))
