While you should always uphold the case-sensitive tablenames, it can be troublesome when migrating from a host that had this option enabled (table & column. Whenever you create database in MySQL, the database/schema has a character set and a collation. All the inside tables are InnoDB with same charset and collation as mentioned. by default, MySQL does not consider the case of the strings This is not quite true.

Here's the gist of what I have: $query = "SELECT id, username, aes_decrypt(lastname,'$vark') AS lastname FROM $dbtable WHERE lastname=aes_encrypt('$lastnameSearch','$vark') ORDER BY id DESC" I'm trying to search through a table via php but having difficulty with case - The problem is the data I'm searching through is encrypted (aes_encrypt) and it doesn't seem to matter what I do the search is case sensitive - I want the search to ignore case. SQL keywords are by default set to case insensitive that means that the keywords are allowed to be used in lower or upper case.
