我是Python和SQL的新手。我正在尝试创建一个简单的代码来创建和访问一个数据库，然后创建一个表，以便试图理解SQL的工作原理。为了做到这一点，我有以下代码：

import mysql.connector
from companyClient import client

def createTable():
    cursor.execute("CREATE TABLE Clients" 
         "(id INT NOT NULL AUTO_INCREMENT,"
        "name VARCHAR (32) NOT NULL,"
        "surname VARCHAR (64) NOT NULL,"
        "PRIMARY KEY (id));")

    print("Table created!")


def showTable():
    print("************** Clients Table *************\n")
    tableContent = cursor.execute("SELECT * FROM Clients")
    

def createEntry():
    cursor.execute("INSERT INTO Company.Clients (name, surname) VALUES ('John','Smith')")

def addUser(userToAdd):
    try:
        cursor.execute("INSERT INTO Company.Clients VALUES %s, %s, %s", userToAdd.id, userToAdd.name, userToAdd.surname)
    except:
        print("It is not possible to add the user. Please try again.")

def findUser(userToFind):
    if(cursor.execute("SELECT * FROM Company.Clients WHERE id = %s "), userToFind.id) :
        return True
    else:
        return False

def removeUser(userToRemove):
    try:
        cursor.execute("REMOVE * FROM Company.Clients WHERE id = %s ", userToRemove.id)
    except:
        print("It is not possible to remove this user. Please try again.")

#server connection 
conexion = mysql.connector.connect(
    host="localhost",
    user="********",
    passwd="*********",
    database="Company"
)

cursor = conexion.cursor()
showTable()

我正在使用SQL Workbench来管理数据库。我已经调用了createTable函数在Company数据库中创建了表“Clients”。使用SQL Workbench，我已经添加了一个条目，只是为了检查我如何在Python中获取该条目。然而，当我调用showTable函数时，tableContent的值是空的。除了当前的查询SELECT * FROM Clients之外，我还尝试了SELECT * FROM Company.Clients，得到了完全相同的结果。我如何正确访问表中的条目？
