MySQL Error 1145: GRANT Host/User Argument Too Long
Description
This error indicates that the username or hostname specified in a MySQL GRANT statement exceeds the maximum allowed length. It typically occurs when attempting to create new users, grant privileges, or modify existing user permissions with very long identifiers.
Error Message
The host or user argument to GRANT is too long
Known Causes
3 known causesExcessive Username/Hostname Length
MySQL enforces internal maximum length limits for both user and host identifiers. Specifying a username or hostname that exceeds these limits in a GRANT statement will trigger this error.
Malformed Identifier Input
Accidentally including extra characters, special symbols, or very long, unintended strings when defining a user or host can cause the argument to exceed MySQL's length constraints.
Overly Long Hostname Specification
Using exceptionally long fully qualified domain names (FQDNs) or complex IP address ranges as the host argument can push the identifier beyond MySQL's maximum length, leading to this error.
