Purpose of ALTER Command in SQL | SQL Shorts

In this YouTube Short, understand the purpose of the ALTER command in SQL — one of the most common DBMS and SQL interview questions.

The ALTER command is used to modify the structure of an existing table, such as:
• Adding a new column
• Dropping (removing) a column
• Modifying column datatype
• Renaming a column or table
• Adding or removing constraints

Very important for Data Analysts, SQL learners, DBMS students, and interview preparation.
