使用Python 实现数据库表结构同步

import pymysql

dbDict = {"test1":"l-beta.test1"}
dbUser = "test"
dbPassword = "123456"

class DBUtils():
  def __init__(self):
    self.conn = pymysql.connect(dbDict['test1'], dbUser, dbPassword)
    self.cursor = self.conn.cursor()

  def dbSelect(self, sql):
    print("------------------------------------")
    print(sql)
    resultList = []
    self.cursor.execute(sql)
    result = self.cursor.fetchall()
    columns = self.cursor.description
    for val in result:
      tempDict = {}
      for cloNum in range(len(columns)):
        tempDict[str(columns[cloNum][0])] = val[cloNum]
      resultList.append(tempDict)
    print("---------------------打印查询结果----------------------")
    print(resultList)
    self.dbClose()
    return resultList

  def dbExcute(self, sql):
    print(sql)
    self.cursor.execute(sql)
    self.dbClose()

  def dbClose(self):
    self.conn.commit()
    self.cursor.close()
    self.conn.close()


if __name__ == "__main__":
  test = DBUtils()
  result = test.dbSelect("select table_name from information_schema.tables where table_schema='testdb1'")
  for dict1 in result:
    test = DBUtils()
    create_table_sql = "create table testdb.%s as select * from testdb1.%s" % (dict1['table_name'],dict1['table_name'])
    print(create_table_sql)
    test.dbExcute(create_table_sql)
