Memcached delete Command

The Memcached delete command is used to delete an existing key.

Syntax:

The basic syntax format for the delete command is as follows:

delete key [noreply]

Parameter descriptions are as follows:

set tutorialpro 0 900 9
memcached
STORED
get tutorialpro
VALUE tutorialpro 0 9
memcached
END
delete tutorialpro
DELETED
get tutorialpro
END
delete tutorialpro
