    Details

      Description

      We do not seem to have a multi-table-specific variation for this assertion failure yet.

      CREATE TABLE t (f INT NOT NULL);
      INSERT INTO t VALUES (0),(0);
      --error WARN_DATA_TRUNCATED
      UPDATE t AS t1 LEFT JOIN t AS t2 ON t1.f <=> t2.f SET t2.f = NULL; 
       
      # Cleanup
      DROP TABLE t;

      Reproducible with at least MyISAM and InnoDB.
      Not reproducible on 10.1.
      No obvious problem on a non-debug build.
