Recently MySQL added the ability to write Stored Programs in JavaScript.  This allows developers to leverage JavaScript capabilities for complex data processing and business logic within the database server. We think this is really cool. Here’s why. Why JavaScript? It is ubiquitous It has multiple runtimes It has a huge development eco-system What’s great about […]

MySQL 9.0 is an Innovation Release, but as you may have read in my Quick Peek, I found little innovation. However, one new item caught my eye, and it could be a way to track query performance. MySQL 9.0 EXPLAIN enhancement Here is the syntax that will be referenced in the post. {EXPLAIN | DESCRIBE […]

In this article, we will demonstrate how to have a single MySQL database user account that can connect from specific hosts. We would usually implement it by creating separate user accounts with the same username but different hosts/IPs like <USER>@<HOST1>, <USER>@<HOST2> …. <USER>@<HOSTn>. Then, give those users the same grants(privileges/roles) and settings(password, SSL, etc). Instead […]

Regular expressions are a powerful tool for developers. In this post we will demonstrate how to use regular expressions subexpressions in MySQL

As I have discussed, regular expressions can be a powerful tool for developers. When we use regular expressions to match a pattern and need to replace part of that pattern, subexpressions make it much easier. Subexpressions are specific parts of a pattern that we can reference elsewhere in the process. The Requirement The requirement for […]

MySQL is certainly a powerful open source database management system, but even the most robust engine struggles when queries take an eternity to execute. For DBAs and developers, improving MySQL query performance is an ongoing goal. Efficient query performance is crucial for ensuring the smooth operation and optimal user experience of applications powered by MySQL […]

In my last post about regular expressions (regex), I offered up a solution to requirements to extract text a substring from a larger blob of text. Over the weekend, I was thinking about this solution and wanted to know if it was possible to meet the requirements using a solution based solely on a regular expression. It […]

Regular expressions are a powerful tool for developers. In this post we re-examine a solution from a previous post to see if we can streamline the query and use a pure regex solution.
