HI, I don't know is it bad or not but I face queries the work quite long time.
the sql is : select * from log_answers_index limit 0,10 and it takes too much time for me to receive the result. I got indexes on most of the fields, i got primary key which is auto_increment int(11). When I did explain on the query I got this : type : ALL rows : 123010 all other cells are empty. When I do : select * from log_answers_index where log_entry_index between 1 and 10 i got type : range For me it is strange that the primary key is not used when there is LIMIT clause without WHERE one.
