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。
