INDEX_STATISTICS updated upon ANALYZE TABLE .. PERSISTENT ...

    XMLWordPrintable

Details

    Description

      ANALYZE TABLE .. PERSISTENT FOR .. INDEXES or FOR ALL shows up in INDEX_STATISTICS. I doubt it is meant to be so (although maybe there is no way to avoid it).

      SET @userstat.save= @@userstat;
      set global userstat= 1;
       
      create table t (a int, key(a)) engine=MyISAM;
      insert into t values (1),(2),(3),(4);
      flush index_statistics;
      analyze table t persistent for all;
      show index_statistics;
       
      # Cleanup
      set global userstat= @userstat.save;
      drop table t;
