ups....sorry - i forgot to attach the database :-) (See attached file: econDB.dump) ------------------------------------------------------- hello mysql-team, i am sorry if i do not correctly report this bug, but i do not know how i should make it sure with a script, that you can verify or repeat this bug. however i have a dump of my mysql-database attached to this mail and hope it will be enough. i am using mysql source distribution 3.23.36 with bdb-tablehandler on a linux server. my problem is that the result sets i receive from my tables are not always correct. if i do the select statement: >SELECT MA_Key FROM Counsel_Skill WHERE MA_Key=1 AND CO_Key=1 GROUP BY MA_Key the result set should contain one record (1). sometimes (and i do not know when and why) i receive an empty result set. if this error occurs i do the select statement: >SELECT MA_Key FROM Counsel_Skill WHERE MA_Key=1 AND SK_Key=10 GROUP BY MA_Key and afterwards the first select statement again: >SELECT MA_Key FROM Counsel_Skill WHERE MA_Key=1 AND CO_Key=1 GROUP BY MA_Key and then it works!!!!! i do not understand this - can you help me with this problem - it is really important!!!! thanks a lot bye kerstin
