Query doesn't delete all data it should after update to 11.8.4

    XMLWordPrintable

Details

    • Unexpected results
    • DELETE from the MyISAM or Aria table that had WHERE clause with the non-unique indexed column col=const and EXPLAIN showing "range" on that column, could have deleted only two rows, not all that match the WHERE clause.

    Description

      When I run query

      DELETE FROM `transaction`
      		 
      WHERE product_id = 'p6cA'
      		 
      AND date_of_transaction > '1970-01-01' + INTERVAL 7 DAY
      		 
      AND date_of_transaction < '2024-09-07' - INTERVAL 7 DAY

      on the table contained in the dump file, version 11.8.3 correctly deletes 606 but version 11.8.4 deletes only two rows ( if I then repeatedly run query again, only two rows gets deleted every time ), affects both Aria and MyISAM as per my testing.

      I tried to create more minimal example of this behavior but to no avail, so I suspect it has something to do with the index or data itself.
