MySQL Error 3513: Unequal Bitwise Operand Lengths
Description
This error occurs when MySQL detects that the two operands in a bitwise operation (e.g., AND, OR, XOR, shifts) do not have the same number of bits. MySQL requires both sides of a bitwise operator to be of equal length for the operation to proceed correctly, often due to implicit type conversions.
Error Message
Binary operands of bitwise operators must be of equal length
Known Causes
3 known causesImplicit Type Conversion
MySQL might implicitly convert one operand to a different size during an operation, leading to a length mismatch with the other operand.
Mismatched Integer Data Types
Performing bitwise operations on columns defined with different integer sizes (e.g., TINYINT and BIGINT) without explicit casting.
Mixing Binary Strings and Integers
Attempting bitwise operations between a VARBINARY string and an integer value, where their internal bit lengths differ.
