Description

Bitwise XOR.

The result type depends on whether the arguments are evaluated as binary strings or numbers:

  • Binary-string evaluation occurs when the arguments have a binary string type, and at least one of them is not a hexadecimal literal, bit literal, or NULL literal. Numeric evaluation occurs otherwise, with argument conversion to unsigned 64-bit integers as necessary.

  • Binary-string evaluation produces a binary string of the same length as the arguments. If the arguments have unequal lengths, an ER_INVALID_BITWISE_OPERANDS_SIZE error occurs. Numeric evaluation produces an unsigned 64-bit integer.

Syntax

create table t1(a int, b int unsigned);
insert into t1 values (-1, 1), (-5, 5);
