Python獲取MySQL的創建表sql，保存到文件中

import os
import pymysql


path = r'D:\Projects\sql'
if not os.path.isdir(path):
    os.mkdir(path) 

conn = pymysql.connect(host='192.168.1.17', user='root', passwd="password", db='db1')
cur = conn.cursor()
cur.execute('''SELECT 
    TABLE_SCHEMA,TABLE_NAME
    FROM information_schema.tables
    WHERE TABLE_SCHEMA in('db1')
    ORDER BY TABLE_SCHEMA,TABLE_NAME''')
table_list = cur.fetchall()
for table in table_list:
    sql = 'show create table `{}`.`{}`'.format(table[0], table[1])
    print(sql)
    cur.execute(sql)
    create_table_list = cur.fetchall()
    create_table_sql = create_table_list[0][1]    
    create_table_sql = create_table_sql.replace('CREATE TABLE ', 'CREATE TABLE `{}`.'.format(table[0]))
    #print(create_table_sql)
    # 每個建表sql保存到一個文件
    filepath = os.path.join(path, '{}.{}.sql'.format(table[0], table[1]))
    with open(filepath, 'w') as rows:
        print(create_table_sql, file = rows)

cur.close()
conn.close()
