In SQL, the WHERE clause filters rows returned by the FROM clause table in SELECT queries using one or more search condition filters. Oftentimes, in application development, we accept user input values which in turn, are the WHERE clause conditional filters against the table columns.

CodeIgniter 4 Query Builder class has an update() function used to process UPDATE Data Manipulation Language (DML) commands. Using update() as a standalone function call is perfectly valid. However, there is also a set() function used for setting column values as you would with the SET keyword in an SQL UPDATE statement.

I recently learned how to use MySQL to generate MySQL statements for several admin-type Data Definition Language (DDL) SQL queries I needed to execute on the server. For many DBA’s this is likely nothing new and in fact, is a well-used tool in their kit. However, I mostly focus on developer-related tasks, so it is a fresh-in-my-mind learning experience.

Some backstory for context

I’ve recently been porting over an existing vanilla PHP application to CodeIgniter 4. One of the new features is bootstrapping all of the necessary MySQL CREATE TABLE statements dynamically based on information parsed from a .fxl file (which is close kin to a .xml file structure-wise).
