The Row Level Locking Message Explained

Screenshot of the row level locking message

A block cipher is a method of encrypting text in which a cryptographic key and algorithm are applied to a whole block of data at once, rather than to each bit at a time.

Row level locking (or record level locking) is where a record is locked whenever it is updated. This is to prevent other users from accessing data being while it is being updated.

When you update a record in an encrypted database that uses row level locking, only the record (row) is encrypted, not the whole database.

When you encrypt a database with row level locking disabled, you will receive the Encrypting with block cipher is incompatible with row level locking. Row level locking will be ignored. message.

What this means is that the whole database will be encrypted — not just the record.
