We saw in the previous post how we can deal with data stored in the new VECTOR datatype that was released with MySQL 9.0. We implemented the 4 basic mathematical operations between two vectors. To do so we created JavaScript functions. MySQL JavaScript functions are available in MySQL HeatWave and MySQL Enterprise Edition (you can […]

In this article we see how we can create a component to add UDFs functions to deal with the VECTOR datatype in MySQL.

MySQL 9.0.0 has brought the VECTOR datatype to your favorite Open Source Database. There are already some functions available to deal with those vectors: This post will show how to deal with vectors and create our own functions to create operations between vectors. We will use the MLE Component capability to create JavaScript functions. JS […]

MySQL Shell offer many features to make life easier for DBAs and developers. In this post we discuss some of the options available to when exporting table data to different formats.

We already discussed how we can use MySQL Shell to dump and load data using a multithreaded process. In this post, we will discuss ways we can export data from a table into different formats. Table Export Utility In the global util object in MySQL Shell, there is a method we can use to export table data to various formats (tab-delimited, comma-delimited, etc.). […]

In my last regular expressions post, we discussed subexpressions and how to isolate specific parts of our pattern match. We can then use those subexpressions to replace parts of our pattern with other text. This post will discuss backreferences and how we can use them as part of our pattern match. Backreferences? In regular expressions, backreferences […]
