How to Remove a Table from a Database: SQL Command Guide

The correct SQL command to remove a table from a database is 'drop'.

Here's why:

• 'drop' permanently deletes a table and all its data from the database.
• 'truncate' removes all data within a table but keeps the table structure intact.
• 'alter' is used to modify table structures, not for removing tables.
• 'insert' is used to add data to a table, not for deleting tables.

Therefore, to effectively delete a table, the 'drop' command is the only appropriate choice.
