Encrypted fields showing up as empty
To explain my situation first...
I have a table with some empty fields and some numbers I wish to encrypt.
I perform a select statement to check how many fields are not empty (I get 56), e.g
"SELECT number from customer WHERE NOT number = '' ";
I then encode this using AES_ENCRYPT(number,keystr)
Then try the count query again as written above but this time I have fewer entries (I get 3) that are not empty.
Any ideas why this may be?
