Hello, I have a table that i use to store session
Table Session ID: VARCHAR(16); /* GUID ID */ Expiry_date: Timestamp; Data: Varchar(1000); i use the table like this only : Insert into Session(ID,Expiry_date,Data) VALUES (CHAR_TO_UUID(NewGUID), NOW + 15minutes,...) Update Session Set data=... Expiry_date= NOW + 15minutes where id=... and Date_expired < 'NOW' Select ... from SESSION where ID=... and Expiry_date > 'NOW' THat ok, now the probleme is that i have another thread that one time a day delete all the expired node Delete From SESSION where Expiry_date < NOW - 3 days i use isc_tpb_write + isc_tpb_read_committed + isc_tpb_no_rec_version + isc_tpb_wait for this second thread (but normally as i delete the rec that expire 3 days ago they must not be any probleme of deadlock) but the probleme is that this SQL make hours (days?) to return :( if i replace the isc_tpb_wait by isc_tpb_nowait then i have often some deadlock (why ?? still not understand ...)
