MySQL Error 3944: Query Row Format Restriction
Description
This error indicates that a submitted SQL query violates the `require_row_format` system variable's constraints. It typically occurs when MySQL is configured to enforce row-based replication safety, and the query uses operations that are not considered safe for this format, preventing its execution.
Error Message
The query does not comply with variable require_row_format restrictions.
Known Causes
3 known causes`require_row_format` Enabled
The MySQL server's `require_row_format` system variable is set to `ON`, enforcing that all statements must be safe for row-based replication.
Non-Row-Format Safe Query
The executed SQL query contains operations (e.g., certain DDL, DML, or `LOAD DATA INFILE` statements) that are not considered safe for row-based replication.
Replication Mode Incompatibility
The current replication setup or intended use case requires stricter row-format compliance than the submitted query provides, leading to a rejection.
