MySQL cannot execute the statement because the supplied ENCRYPTION option is not supported.
MySQL Error 3184 (ER_INVALID_ENCRYPTION_OPTION) means the server rejected an unsupported ENCRYPTION value in a CREATE, ALTER, or SET statement. Use only valid options such as ENCRYPTION='Y' or ENCRYPTION='N', then rerun the command to fix the issue.
ER_INVALID_ENCRYPTION_OPTION
The server throws MySQL Error 3184 with the message Invalid encryption option when a statement contains an ENCRYPTION clause that MySQL does not recognise. The check occurs before the operation is applied, so no data changes are committed.
The error was introduced in MySQL 5.7.11 when InnoDB table encryption became available. It commonly appears in CREATE TABLE, ALTER TABLE, and SET operations that touch file‐level or tablespace encryption settings.
The primary trigger is supplying an unsupported value to the ENCRYPTION option. MySQL 5.7 and 8.0 only accept 'Y' or 'N' (or the keywords YES and NO). Any other string, a misspelling, or an empty value returns error 3184.
The error can also arise when the clause is used in a context where encryption is not permitted, such as a temporary table, a non‐InnoDB engine, or when the innodb_file_per_table setting is OFF.
Replace the invalid option with a supported value and ensure the target object supports encryption. Confirm that the InnoDB plugin is active and innodb_file_per_table is ON. After corrections, rerun the statement.
If the clause is not required, remove it entirely. MySQL defaults to the server's innodb_encrypt_tables setting when the ENCRYPTION clause is absent.
Mistyped value - ENCRYPTION='YES' instead of ENCRYPTION='Y'. Change it to 'Y' or 'N'.
Non‐InnoDB engine - MyISAM tables do not support ENCRYPTION. Switch to ENGINE=InnoDB or drop the clause.
Global variable update - SET GLOBAL innodb_encrypt_tables='AUTO'; will fail because the variable accepts OFF, ON, or FORCE. Supply a valid constant.
Always validate allowable values in the MySQL manual for your server version. Apply syntax highlighting or linting in a modern editor like Galaxy to catch typos early. Use configuration management to standardise DDL scripts and keep server variables aligned.
Enable strict SQL modes in development to surface syntax errors sooner, and include unit tests for schema migrations.
MySQL Error 3183 ER_INVALID_ENCRYPTION_ALGORITHM occurs when the algorithm name is invalid. MySQL Error 1105 may appear if encryption metadata is missing. Their fixes follow the same pattern: supply only supported constants and verify plugin availability.
Values other than 'Y' or 'N' immediately trigger the error.
Only InnoDB tablespaces honour the ENCRYPTION clause. Other engines reject it.
Per‐table encryption requires file‐per‐table mode. Disablement blocks the ENCRYPTION clause.
Older 5.6 versions do not recognise the ENCRYPTION syntax at all.
Raised when an unsupported encryption algorithm is supplied. Use 'AES' on supported builds.
Appears when MySQL cannot encrypt or decrypt the tablespace after a valid ENCRYPTION clause. Check file permissions and keyring plugins.
Occurs in keyring_aws setups when the KMS key is invalid. Verify the ARN and IAM policies.
No. The statement is rejected before execution, so no changes reach disk.
Versions 5.7.11 and later recognise ENCRYPTION='Y' or 'N'. Earlier releases will throw a syntax error.
No. Convert the table to InnoDB first, then apply ALTER TABLE ... ENCRYPTION='Y'.
Galaxy highlights invalid option values in the editor and autocompletes valid ENCRYPTION settings, reducing typos that cause error 3184.
