SQL/python/README.md

記得安裝 pymysql

pip install pymysql

資料庫連線設定

import pymysql
db = pymysql.connect(host='140.125.21.65', port=3307, user='VIP125', passwd='@VIPvip125', db='VIP125',
                     charset='utf8')

建立操作游標

cursor = db.cursor()

SQL語法（查詢資料庫版本）

sql = 'SELECT VERSION()'

執行語法

cursor.execute(sql)

選取第一筆結果

data = cursor.fetchone()
print("Database version : %s " % data)

資料讀取(全部)

sql = "select * from test_0525_01"
cursor.execute(sql)
data = cursor.fetchall()
print(f'ALL_data = {data}')

查詢資料(單獨)

sql = "SELECT user_id FROM test_0525_01;"
cursor.execute(sql)
data = cursor.fetchall()
print(f'user_id = {data}')

查詢資料(某筆)

sql = "SELECT *  FROM test_0525_01 WHERE user_id='1000';"
cursor.execute(sql)
data = cursor.fetchall()
print(f'user_id=1000 : {data}')

刪除資料

sql = "DELETE FROM test_0525_01 WHERE user_id='1001';"
cursor.execute(sql)
db.commit()

更新資料

sql = "UPDATE test_0525_01 SET user_name='user_update_1000' WHERE user_id='1000';"
cursor.execute(sql)
db.commit()

資料寫入

test_data = ['1001', 'test_1001']
sql = "INSERT INTO test_0525_01 (user_id,user_name) VALUES (%s,%s);"
cursor.execute(sql, test_data)
db.commit()

關閉連線

db.close()
