我是Python和SQL的新手。我正在嘗試建立一個簡單的程式碼來建立和存取一個資料庫，然後建立一個表，以便試圖理解SQL的工作原理。為了做到這一點，我有以下程式碼：

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來管理資料庫。我已經呼叫了createTable函數在Company資料庫中建立了表格「Clients」。使用SQL Workbench，我已經新增了一個條目，只是為了檢查我如何在Python中取得該條目。然而，當我呼叫showTable函數時，tableContent的值是空的。除了目前的查詢SELECT * FROM Clients之外，我還嘗試了SELECT * FROM Company.Clients，得到了完全相同的結果。我如何正確存取表中的條目？
