The DELETE Statement

The DELETE statement is used to delete rows in a table.

SQL DELETE Syntax

DELETE FROM table_name
WHERE some_column=some_value

where id="sam";
==============================================================

DELETE FROM table_name
WHERE some_column=some_value AND some_column=some_value

Delete All Rows

It is possible to delete all rows in a table without deleting the table.
This means that the table structure, attributes, and indexes will be intact:

DELETE FROM table_name;
