Error 74 occurs when a command-line or server option is declared without an accompanying value.
MySQL Error 74: EE_OPTION_WITH_EMPTY_VALUE appears when you supply an option like --user= or SET @@global.var='' without a value. Provide a non-empty value or remove the option to resolve it.
%s: Empty value for '%s' specified. EE_OPTION_WITH_EMPTY_VALUE was added in 8.0.13.
MySQL raises error 74 when it detects an option or system variable that has been declared with an equals sign but no value.
The server or client utility cannot determine the intended configuration, so it aborts execution and returns the error.
The error was introduced in MySQL 8.0.13 to make configuration parsing stricter and prevent silent misconfigurations that could cause security or performance issues.
Empty assignment in command-line options such as --host= or --password= triggers the error immediately after startup parsing.
Setting a server variable to an empty string with SET GLOBAL or SET PERSIST statements also causes the error.
Configuration files (.cnf) that include lines like user="" or socket= raise the error during server startup.
Correct the offending option by supplying a valid non-empty value that meets MySQL’s data-type expectations.
If the option is not required, remove it entirely from the command, configuration file, or SQL statement.
Validate option syntax in CI pipelines or editors like Galaxy to catch empty assignments before deployment.
mysqld startup: The service fails because my.cnf contains socket=.
Provide the correct socket path or comment out the line.
Client login: Running mysql --user= but forgetting the username halts the connection. Re-run with --user=root or similar.
Dynamic variable change: Executing SET GLOBAL sql_mode='' without intention resets sql_mode entirely. Specify a desired mode or omit the statement.
Use configuration management tools that lint .cnf files for empty values.
Quote values containing spaces instead of leaving them blank.
Example: --ssl-ca="/path/ca.pem".
Adopt a Galaxy workspace policy that blocks commits with empty option assignments.
Error 77 EE_UNKNOWN_OPTION: Raised when an unrecognized option is supplied. Verify spelling.
Error 1231 ER_WRONG_VALUE_FOR_VAR: Occurs when a variable value is out of range or invalid type. Provide a value conforming to expected type.
Error 3161 ER_INCORRECT_GLOBAL_LOCAL_VAR: Thrown when attempting to set a read-only variable. Remove the SET command or change scope.
.
Both mysqld and client tools like mysql or mysqldump raise the error if an option lacks a value.
Error 74 EE_OPTION_WITH_EMPTY_VALUE was added in 8.0.13 and exists in all later 8.x and 9.x versions.
No. MySQL requires explicit non-empty values. Remove the option to fall back to default behavior.
Galaxy’s editor flags empty option assignments in scripts and offers AI suggestions to complete missing values.
