![]() We could do this: SELECT senderid, recipientid, min (createdat) FROM messages GROUP BY senderid, recipientid. You can get it done using below query: Schema (MySQL v5.7) create table users( twuserId INT, categoryStatus VARCHAR(100) NOT NULL ) insert into users values. Determining the first message in a conversation is a bit tricky. I have this data in the attached image, some users have a pharmacist category only and some users have a doctor and pharmacist category. The following shows the syntax of the SHOW PROCESSLIST command: SHOW FULL PROCESSLIST Code language: SQL (Structured Query Language) (sql) Accounts with the PROCESS privilege can view all threads. First, we need to define what a conversation is: a pair of (senderid, recipientid) exchanging messages. You then can terminate the idle threads with the KILL statement. ![]() MySQL is ideal for both small and large applications. The SHOW PROCESSLIST command returns all currently running threads. Port : 3306, in the connection info and still nothing as well.Īny idea? Like comment: Like comment: 1 likeĬonst bodyParser = require('body-parser') Ĭonst connection = mysql. MySQL is a widely used relational database management system (RDBMS). The statement requires the SELECT privilege for the mysql system schema, except to see information for the current user. get ( ' /users ', function ( req, res ) )) Īs proposed before in the comments but still nothing. const app = express () // Creating a GET route that returns data from the 'users' table. Next stop is the make sure you can always access that user variable. To do that, you would have to go through the user list, and once the credentials match, return the user. We're still in routes.js! Right below everything else. Even though there is no such command, users can use a MySQL query and get a full list of users in a given MySQL database server. So first off how to get the user, in your log in controller class, where you check if the user exists, and whether the credentials are correct.
