近日,某个QQ 群里的一个朋友提出一个问题,如何将一个DB 的表结构同步给另一个DB。
针对这个问题,我进行了思考与实践,具体的实现代码如下所示:

# coding:utf-8 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) |
示例代码操作简单,通俗易懂,所以没有过多的注释,如有疑问的小伙伴们,可在文章下方评论。
