SQL command for creating a table
Use CREATE TABLE statement
Specify table name and column names with data types
Add any constraints or indexes as needed
SQL commands for inserting, updating, and deleting data from a table.

Truncate and drop are SQL commands used to remove data from a table.
Truncate removes all data from a table but keeps the structure intact.
Drop removes the entire table and its structure.
Truncate is faster than drop as it only removes data.
Drop cannot be undone while truncate can be rolled back.
Truncate resets the identity of the table while drop does not.
Examples: TRUNCATE TABLE table_name; DROP TABLE table_name;
