While some software applications can live in an ecosystem where all dates and times can be stored in a single time zone with no conversions needed, many cannot.

In the last few articles in this series, you learned about three important data manipulation language (DML) statements: SELECT, INSERT, and UPDATE. The statements make it possible to retrieve, add, and modify data in a MySQL database. Another DML statement that is just as important is DELETE, which lets you remove one or more rows from a table, including temporary tables. In this article, I focus exclusively on the DELETE statement to help round out our discussion on the core DML statements in MySQL. Overall, the DELETE statement is fairly basic, but one that’s no less necessary to have in your arsenal of DML tools.

Object Relational Mapping is a database abstraction technique that aids developers in manipulating and interacting with SQL databases using the data types provided in the programming language. ORMs (Object Relational Mappers) are tools (libraries, modules, packages) that provide the functionality for interacting with SQL databases. Popular ORMs are the Prisma ORM for JavaScript, TypeScript, Hibernate … Read more
At the turn of the millennium, I was a young adult, just finished education and starting my very first job at a software company. I was excited, enthusiastic, and felt well-prepared for a life of “Office 9 to 5” and was looking forward to earning my keep. But I was naïve when it came to … Read more

The previous installment of this series examined aggregate subquery removal and subquery coalescing, describing the latter as similar in some ways to an inverse for “Or Expansion” and “Join Factorization”. In this instalment, it’s time to take a closer look at Or Expansion and we’ll move on to Join Factorization in the next instalment.… Read more
Once data is inserted into a table, data typically needs to be maintained as time goes on. To make changes to an existing row or a number of rows, in a table, the UPDATE statement is used.

In the previous article in this series, I introduced you to the SELECT statement, one of several SQL statements that fall into the category of data manipulation language (DML), a subset of statements used to query and modify data. Another DML statement is the INSERT statement, which lets you add data to MySQL tables, both … Read more
Before data can be read from of a SQL Server database table, the table needs to contain rows of data. One of the most typical ways to get data into a table is to use the INSERT statement. One row or multiple rows can be inserted with a single execution of an INSERT statement. You … Read more
For the first time in eleven years of travel, I became profoundly sick while on the road. No, I’m not sharing details of any kind. What I will share is just this; I wasn’t prepared. When I travel, I look at the weather, where I’m going, how long, and I pack accordingly. I have my … Read more
I book my travel almost exclusively through a single airline and its affiliates. There are a lot of reasons for this, but the big one is status. And no, not so I get upgrades (although they are very nice), but so when things go wrong, I have a hotline to getting them fixed. However, I … Read more
Said no manager ever. Money is the one thing every candidate at any job interview is advised never to mention. The salary on offer for the role is treated almost like a *dirty secret. Job advertisements only reveal a band or range, which makes sense to a certain extent, given that the candidate may be … Read more
