Python 如何實現數據庫表結構同步
近日,某個QQ 群里的一個朋友提出一個問題,如何將一個DB 的表結構同步給另一個DB。針對這個問題,我進行了思考與實踐,具體的實現代碼如下所示:
# coding:utf-8import pymysqldbDict = {'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('---------------------打印查詢結果----------------------') 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)
示例代碼操作簡單,通俗易懂,所以沒有過多的注釋,如有疑問的小伙伴們,可在文章下方評論。
