MySQL throws Error 1141 when you try to revoke, drop, or display a privilege set that was never granted to a specific user@host combination.
MySQL Error 1141: ER_NONEXISTING_GRANT means the server cannot find the requested privilege entry for the given user@host. Check the exact user and host strings, list current privileges with SHOW GRANTS, and only revoke or drop privileges that actually exist for that account.
There is no such grant defined for user '%s' on host '%s'
Error 1141 appears with the message “There is no such grant defined for user '%s' on host '%s'.” The server is telling you that the privilege set you are trying to revoke, alter, or inspect does not exist in the mysql.user or mysql.db privilege tables.
The error commonly surfaces during REVOKE, SHOW GRANTS FOR, or DROP USER statements on MySQL 5.0+ and MariaDB.
It blocks the operation because the server cannot match any existing GRANT entries for the supplied user and host.
Missing privilege rows are the primary trigger. The account was never granted the privilege, or the record was deleted manually from the privilege tables.
A typo in the user or host portion of the statement can also cause the mismatch.
Replication or migration scripts that revoke privileges out of order frequently hit Error 1141 when they reference users that were already cleaned up on the target server.
First, confirm the exact user@host string. Run SELECT User, Host FROM mysql.user; or SHOW GRANTS FOR 'user'@'host'; to see what exists.
If no rows appear, the account or grant truly does not exist.
Next, adjust your REVOKE or DROP statement to match an existing grant, or issue a GRANT first if you must later revoke it. Always flush privileges or restart the server after direct table edits.
Automated scripts that run REVOKE before GRANT in idempotent deploys often fail on the first run.
Guard the REVOKE with IF EXISTS logic or try-catch handling where supported.
When cloning production to staging, grants for wildcard hosts like '%' might differ. Normalize hosts in your scripts or query the privilege tables to build dynamic REVOKE statements that match.
Keep user creation, grants, and revokes in source control. Use idempotent migration tools that check for grant existence before revoking.
Validate hostnames, especially if DNS or IPs changed.
Galaxy’s SQL editor highlights syntax errors and offers schema-aware autocomplete, reducing typos in user and host identifiers. Collections let teams version controlled GRANT scripts, preventing drift across environments.
MySQL Error 1044 (ER_DBACCESS_DENIED_ERROR) appears when you lack privileges on a database. It differs because the user exists but lacks rights.
Grant the required privileges rather than checking grant existence.
Error 1396 (ER_CANNOT_USER) occurs when creating a user that already exists. Use CREATE USER IF NOT EXISTS or drop the user first to resolve.
.
Mis-spelling the username or specifying an incorrect host like 'localhost' instead of '%' leads MySQL to miss the grant row and raise Error 1141.
If a previous script removed the account, subsequent REVOKE or SHOW GRANTS commands will fail because no grant rows remain.
Privileges may exist for 'user'@'%' but you are revoking 'user'@'localhost'.
MySQL treats them as different identities, so the grant search fails.
Direct deletes from mysql.user or mysql.db remove rows without updating scripts, causing later operations to reference missing grants.
.
No. REVOKE assumes the grant exists and raises Error 1141 if it does not. Add guard logic or query privilege tables first.
The error is built into the privilege system and cannot be disabled. Code defensively instead.
The account string you supplied does not match any row in mysql.user. Verify both user and host exactly.
Galaxy’s editor autocompletes valid user and host tokens, highlights mismatches, and lets teams version control GRANT scripts to avoid drift.
