MariaDB Error 1706: Conflicting Key Update Paths
Description
This error occurs when an `UPDATE` statement attempts to modify a primary key or partition key column, but the target table is referenced multiple times within the same statement. MariaDB detects conflicting or ambiguous paths for updating the key, disallowing the operation to prevent data inconsistency.
Error Message
Primary key/partition key update is not allowed since the table is updated both as '%s' and '%s'.
Known Causes
3 known causesSelf-Join Ambiguity
An `UPDATE` statement uses a self-join or aliases that cause the database to detect multiple, conflicting attempts to modify the same primary or partition key within the transaction.
Complex Subquery Referencing
A subquery within the `UPDATE` statement refers to the same table being updated, creating an unclear or ambiguous path for the primary/partition key modification.
Indirect Key Modification Conflict
The overall structure of the DML operation, possibly involving views or triggers, leads to the primary or partition key being targeted for update through more than one logical route simultaneously.
