hello

i have an table with about one million rows , and all my queries is just select by id , what is the best practice to enhance the performance of this table ?

thanks

Best answer I can give with the little detail provided: clustered index on the ID field.

thanks for replaying gvee

i have table `topics` like that
id - title - topic
1 one topic num one
2 two topic num. two
3 three topic num. three
. . .
. . .
. . .
1000000 million topic num. million

and when i want to retrieve topic contents i use this query

SELECT `topic` FROM `topics` WHERE `id`= $topicId ;

sometimes query like that take some time one second or two

so i wonder how can i enhance that ,
