How to Safely Add a New Column Without Breaking Production

How to Safely Add a New Column in SQL Without Downtime

A new column can break or save your data. One wrong move and queries slow, indexes fail, or production locks. Done right, it opens new capabilities with no downtime. The difference is planning. Adding a new column in SQL is not just syntax. You choose data types, defaults, nullability, and
