The BIT data type is used to store bit values. If you assign a value to a BIT(M) column that is less than M bits long, the value is padded on the left with zeros. For example, assigning a value of b'101' to a BIT(6) column is, in effect, the same ...

In numeric contexts, MySQL treats a bit literal like an integer. To ensure numeric treatment of a bit literal, use it in numeric context. For example, a bit literal assigned to a user-defined variable is a binary string by default. To convert a bit ...A leading 0b is case-sensitive and cannot be written as ...

block_encryption_mode takes a value in aes-keylen-mode format, where keylen is the key length in bits and mode is the encryption mode. For example, this statement causes the AES encryption functions to use a key length of 256 bits and the CBC mode: ... The MySQL server maintains many system variables that affect its ...
