DROP Command

SQL Drop command used to remove a table definition and all the data, indexes, triggers, constraints and permission specifications for that table.

Drop command is used to delete table structure as well as all of table data.

If you may use SQL DROP command, You should be very careful. Because, once a table is deleted then all the information available in that table will also be lost forever. In other words we can say that we didn't rollback this data.

In short, DDL commands are auto-committed that means it permanently save all the changes in the database.

We didn't drop entire row. Because, this command is used only for drop whole table (table data and table structure )  or database.
