Description

This error indicates an attempt to create a table with encryption settings that conflict with the encryption configuration of the target tablespace. It commonly occurs when trying to mix encrypted and unencrypted objects or keys in an incompatible manner.

Known Causes

3 known causes

⚠️

Incompatible Encryption Setting

Attempting to create a table with an encryption attribute (e.g., encrypted or unencrypted) that conflicts with the target tablespace's encryption configuration.

⚠️

Tablespace Lacks Encryption Support

Trying to create an encrypted table within a tablespace that is not designed or configured to store encrypted objects.

⚠️

Encryption Key Mismatch

The specified encryption key or algorithm for the table is incompatible with the default encryption of the tablespace.

Solutions

4 solutions available

1. Create Table with Matching Encryption Settings easy

Ensure the new table's encryption matches the tablespace's encryption.

1

Identify the encryption status of the target tablespace. You can do this by querying the `information_schema.FILES` table.

SELECT FILE_ID, FILE_NAME, TABLESPACE_NAME, ENGINE, COMPRESSION, ENCRYPTION FROM information_schema.FILES WHERE TABLESPACE_NAME = 'your_tablespace_name';

2

If the tablespace is encrypted, create the new table with the same encryption settings. This often involves specifying the `ENCRYPTION` clause during table creation. The exact syntax depends on your MySQL version and whether you're using InnoDB or another engine.

CREATE TABLE your_new_table (...) ENCRYPTION='Y';
-- Or if using a specific algorithm:
CREATE TABLE your_new_table (...) ENCRYPTION='AES';
-- For older versions or specific configurations, you might need to ensure the default tablespace encryption is set correctly.

3

If the tablespace is not encrypted, create the new table without specifying any encryption.

CREATE TABLE your_new_table (...);

2. Recreate Tablespace with Desired Encryption medium

Modify the tablespace itself to have the encryption needed for the new table.

1

Determine the current encryption of the tablespace. Use the query from Solution 1.

SELECT FILE_ID, FILE_NAME, TABLESPACE_NAME, ENGINE, COMPRESSION, ENCRYPTION FROM information_schema.FILES WHERE TABLESPACE_NAME = 'your_tablespace_name';

2

If the tablespace encryption is incompatible, you'll need to recreate it. This involves backing up the data, dropping the tablespace, creating a new tablespace with the correct encryption, and then restoring the data.

SHOW CREATE TABLE your_table_in_tablespace;
-- Backup data from tables in the tablespace
-- DROP TABLE your_table_in_tablespace;
-- DROP TABLESPACE your_tablespace_name;
-- CREATE TABLESPACE your_tablespace_name ... ENCRYPTION='Y'; -- Or desired encryption
-- CREATE TABLE your_table_in_tablespace ... TABLESPACE = your_tablespace_name;

3

After recreating the tablespace with the correct encryption, you can then create your new table within it.

CREATE TABLE your_new_table (...) TABLESPACE = your_tablespace_name;

3. Use a Different Tablespace for the New Table easy

Create the new table on a tablespace that has compatible encryption.

1

Identify or create a tablespace that has the desired encryption settings. You can check existing tablespaces using `information_schema.FILES` or create a new one.

CREATE TABLESPACE new_encrypted_tablespace ADD DATAFILE 'new_encrypted_tablespace.ibd' ENCRYPTION='Y'; -- Or desired encryption

2

Create your new table and explicitly assign it to this compatible tablespace.

CREATE TABLE your_new_table (...) TABLESPACE = new_encrypted_tablespace;

4. Disable Table Encryption Temporarily (If Applicable) medium

For transient issues or testing, temporarily disable encryption.

1

This is generally not a recommended long-term solution as it compromises security. However, if you're in a development or testing environment and encounter this error, you might consider disabling encryption globally or for specific tables if your MySQL version supports it.

-- Check MySQL server variables for encryption settings
SHOW VARIABLES LIKE 'innodb_encrypt%';

-- Temporarily disable (use with extreme caution and only in non-production environments)
SET GLOBAL innodb_encrypt_tables = OFF; -- This might require a server restart depending on version

-- Or for specific tables, if supported by your version:
ALTER TABLE your_table ENCRYPTION = 'N';

2

Create your table while encryption is disabled.

CREATE TABLE your_new_table (...);

3

Remember to re-enable encryption after you've completed your task.

SET GLOBAL innodb_encrypt_tables = ON; -- Or revert to your previous setting
-- Remember to re-apply encryption to existing tables if necessary.
