Why we should close the connection in JDBC? If we don't do it, what will happen

问题 Communicate with the database in java, we often follow these steps: load a driver get a connection create a Statement or PreparedStatement get the ResultSet close the connection I am confused that we should close connection, all say that create a connection is expensive, so why we can't do like this: static { try { connection = DriverManager.getConnection(connectorURL, user, password); } catch (SQLException e) { e.printStackTrace(); } } We just create a connection as a singleton, and use it

问题 I created an Azure Function App in Visual Studio 2015. The App has a trigger for service bus queues. The app works perfectly when I run it locally. It is able to read the data from the Service Bus queue (configured via a variable named AzureSBConnection) and log it in my database. But it gives me the following error when deployed in Azure: Function ($ServiceBusQueueTriggerFunction) Error: Microsoft.Azure.WebJobs.Host: Error indexing method 'Functions.ServiceBusQueueTriggerFunction'.

问题 I've built a simple web application that does some communication through a node.js server using socket.io. When a user connects, node communicates back info which tells the client to subscribe to certain events. That works fine. But if you let the browser set idle, the client ends up subscribed to the events twice. The subscription process works like this: When a user connects node.js gets a 'adduser' message The two key things that hapen in that function are this: socket.on('adduser',

PHP's PDO is ignoring the ATTR_TIMEOUT option for MySQL when server cannot be reached

由 不想你离开。 提交于 2019-12-06 17:02:50
问题 I'm testing scenarios where the mysql server cannot be reached by putting in a random IP to try to connect to. I set PDO's options to time out after one second using PDO::ATTR_TIMEOUT => 1 . However, it still takes 30 seconds to throw an exception. I'm guessing this timeout only applies to the actual mysql connection time, not to the server on which mysql is running. What PHP options do I need to change to time out the connection to the mysql server? 回答1: Just put ini_set("default_socket
