MySQL Tutorial - Order By
MySQL for Engineers / Technologists

MySQL is a freely available open source Relational Database Management System (RDBMS) that uses Structured Query Language (SQL). SQL is the most popular language for adding, accessing and managing content in a database. It is most noted for its quick processing, proven reliability, ease and flexibility of use.

MySQL is an open-source relational database management system. Its name is a combination of "My", the name of co-founder Michael Widenius's daughter, and "SQL", the abbreviation for Structured Query Language.

MySQL Tutorial - Order By
We can use ORDER BY statement to make MySQL results easier to read and understand. A common way to do this in the real world is to order a big list of items by name or amount. The way to order your result in MySQL is to use the ORDER BY statement.

What ORDER BY does is it takes the a column name that you specify and sorts it in alphabetic order (or numeric order if you are using numbers).





Query: Show all records not containing the name "Paul" AND the Alarms on Node 'SCADA3' order by the Time.

SELECT * FROM [table name] WHERE name != "Paul" AND NodeName= 'SCADA3' ORDER BY TimeIn;
