################################################################# #author: 陈月白 #_blogs: http://mit() #确认提交 print("INFO:execute sql sucess. sqlLine = ", sqlLine) except Exception as e: print("ERROR:execute sql failed.errorInfo =",e) print("ERROR:FUNCTION executeSql execute failed.sqlLine =",sqlLine) connect.rollback() #回滚db return str(e) + " sqlLine = " + sqlLine #断开连接 connect.close() print("INFO:connect closed.\n") return executeResult else: print("ERROR:param sqlLine is empty or type is not str.sqlLine = ",sqlLine) def executeBatchSql(self,sqlList): """ 批量执行sql exp: executeBatchSql([sql_1, sql_2, sql_3, ...... ]) """ finalResultList = [] if sqlList: for sql in sqlList: executeResult = self.executeSqlLine(sql) finalResultList.append(executeResult) else: print("ERROR:param sqlList is empty.") return finalResultList

测试代码:

# -*- coding: utf-8 -*-from my_code.work_tools import WorkToolsmysql = WorkTools.MysqlTools("localhost","testdbname","rootuername","passwd")#执行单行sqlret1 = mysql.executeSqlLine("show databases")#批量执行ret2 = mysql.executeBatchSql([ "show databases", "show tables", "update students_info set name = '王大花D' where id = 2", "select * from students_info", "error sql test"  #异常sql测试 ])print("ret1 = ",ret1)print("---------------------")for i in ret2: print(i)

测试表:

执行结果:

ret1 = (('information_schema',), ('mysql',), ('performance_schema',), ('sakila',), ('sys',), ('testdb',), ('world',))---------------------(('information_schema',), ('mysql',), ('performance_schema',), ('sakila',), ('sys',), ('testdb',), ('world',))(('students_info',),)()((1, '陈月白', 'male', 25, '20176666', '1351234'), (2, '王大花D', 'female', 19, '19920816', '10086'), (3, '李强新', 'male', 18, '19941025', '10000'), (4, '王鹏', 'male', 20, '19970405', '10010'), (5, '钟齐', 'male', 22, '19970420', '123456789'), (6, '王大花', 'female', 15, '19981024', '12345678'))(1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'error sql test' at line 1") sqlLine = error sql test
