Extracting Valuable Insights from Your Data

When working with strings in SQL, the SUBSTRING() function is a game-changer. It allows you to extract specific parts of a string, giving you valuable insights into your data. But how does it work?

The Basics of SUBSTRING()

The SUBSTRING() function takes three arguments: the string column, the start position, and the length of the substring. Using this function, you can extract specific parts of a string, such as the first three characters of each customer’s first name.

Taking it to the Next Level: SUBSTRING() with JOIN

But what if you need to extract data from multiple tables? That’s where the power of SUBSTRING() with JOIN comes in. By combining these two functions, you can extract specific data from multiple tables, such as the first five characters of each item name in orders made by UK customers.

Filtering Data with SUBSTRING() and WHERE

Sometimes, you need to filter your data based on specific string patterns. That’s where the SUBSTRING() function with the WHERE clause comes in. By combining these two functions, you can filter your data to include only specific patterns, such as customers whose first name starts with “Jo”.
