MySQL Error 58: Invalid Variable Suffix
Description
This error occurs when MySQL encounters an unrecognized or invalid suffix character (e.g., 'K', 'M', 'G' for size units) appended to a system variable name. It typically happens when attempting to configure global or session variables with an incorrect unit specifier, preventing MySQL from parsing the variable's value correctly.
Error Message
Unknown suffix '%c' used for variable '%s' (value '%s').
Known Causes
4 known causesIncorrect Unit Suffix
Using an invalid or unrecognized size unit suffix (e.g., 'X' instead of 'K', 'M', 'G') with a system variable that expects size values.
Suffix for Non-Unit Variable
Appending a suffix to a system variable that does not accept or interpret unit suffixes, expecting only a raw numeric value.
Case Sensitivity Mismatch
Using an incorrect case for a valid suffix (e.g., 'k' instead of 'K') if the MySQL version or configuration is case-sensitive for unit specifiers.
Typographical Error
A simple typo or accidental character in the suffix when setting a system variable's value in a configuration file or SQL statement.
