python中mysql语句:
1、删除语句,根据条件删除数据
def DeleteInventory(self,Delete_goodsID):
DeleteInventory_sql=("DELETE FROM inventoryinformation WHERE goodsID= %s")
asd = self.conn.execute(DeleteInventory_sql,Delete_goodsID)
return asd
这里 用 %s 代替了传入的参数 Delete_goodsID 然后用其父类BaseBusiness 里面的 execute 方法,来执行SQL语句
2、修改语句,根据条件修改数据
manager_sql=("update manager set managerPassword= %s where managerID= %s ")
3、查询语句,根据条件查询所需的数据
select_sql=("select managerID,managerPassword from manager where managerID= %s and managerPassword= %s
")
4、添加语句,根据条件添加数据
sql=("INSERT INTO customer(customerID,customerName,customerAddress,customerBankAccount,customerPayee,""customerAccountNumber,customerContacts,companyTelephone,contactPhone,customerFax) VALUES(%s,%s,%s,%s,%s,%s,%s,%s,%s,%s)")
这样,基本的增删改查都有了,而且SQL语句中因为是传入的参数,可以避免一些SQL注入问题,还是比较好的
