Adding a New Column in Production Without Fear

The code stopped running. You need a new column.

A new column changes the structure of your data without touching the rest of the table. In SQL, it starts with ALTER TABLE. You define the name, set the data type, and decide if null values are allowed. The command runs. Your schema shifts. A clean new column means less
