In this advanced SQL tutorial, we explore the regex_split_to_table() function, which separates a string by a limiter and returns a table with each element in a separate row. We'll show how this function can be useful for complex manipulations. This video is perfect for those looking to level up their SQL string manipulation skills.

In this video, were going to learn how to use the corr() method to create data showing correlation. In the first part of this tutorial, we discussed how to prepare the data for modeling. In this part, well get acquainted with collinear features and the importance of removing redundancy in our data. By removing redundancy, well be able to improve our datas overall accuracy and make it easier to understand. This is an essential step in data analysis, and youll want to pay attention to it when working with data!
