ingo@mysql.com d0c6eb885d Bug#14980 - COUNT(*) incorrect on MyISAM table with certain INDEX ... For "count(*) while index_column = value" an index read is done. It consists of an index scan and retrieval of each key. For efficiency reasons the index scan stores the key in the special buffer 'lastkey2' once only. At the first iteration it notes this fact with the flag HA_STATE_RNEXT_SAME in 'info->update'. For efficiency reasons, the key retrieval for blobs does not allocate a new buffer, but uses 'lastkey2'... Now I clear the HA_STATE_RNEXT_SAME flag whenever the buffer has been polluted. In this case, the index scan copies the key value again (and sets the flag again).		2006-03-10 15:03:04 +01:00
