MySQL Error 3514: Aggregate Bitwise Argument Too Large
Description
This error indicates that an aggregate bitwise function (such as BIT_AND(), BIT_OR(), or BIT_XOR()) has been called with an argument whose binary representation exceeds the maximum allowed size of 511 bytes. It typically occurs when attempting to perform bitwise operations on large binary strings, VARBINARY columns, or implicitly converted long strings.
Error Message
Aggregate bitwise functions cannot accept arguments longer than 511 bytes; consider using the SUBSTRING() function
Known Causes
3 known causesArgument Exceeds 511 Bytes
The input expression provided to an aggregate bitwise function directly results in a value that, when represented internally, is larger than the 511-byte limit.
Using Large Data Types
Attempting to perform bitwise operations on columns defined as VARBINARY, BLOB, or long VARCHAR that frequently store data larger than 511 bytes without prior truncation.
Implicit Type Conversion
MySQL implicitly converts a string or numeric value to a binary representation for bitwise operations, and this converted value unexpectedly exceeds the 511-byte limit.
