ENCODE()
ENCODE(string,password)
This function encrypts a given string in binary format and
locks it with the password. You should not use this function for the
password column in the user
table of the mysql database. Use PASSWORD() instead. Here is an example:
UPDATE teachers
SET pwd = ENCODE('test', 'oreilly')
WHERE teacher_id = '730522';The function here encrypts the word test and
locks it with the oreilly password. The results
are stored in the pwd column for the chosen
teacher. To unlock the results, use the DECODE()
function with the same password.
