delete table deletes entire table if we want to delete or else we can delete specific column or row.

if we wish to simply get rid of the data but not the table itself? For this, we can use the TRUNCATE TABLE command. The syntax for TRUNCATE TABLE is

TRUNCATE TABLE "table_name"

Answer / kalyan

it deletes the data in the table. And Delete command deletes
the entire table with data.
