In a select query i have used the join conditions, will it affect query performance.Explicitly I didn't used the join command, Will it make any difference.
It'll make sure you don't miss any join conditions between two tables so it'll be helpful in that respect, I didn't read your whole query but with a 7 table join it's very easy to miss doing a match on one or more tables.
It shouldn't take more than a couple of minutes to rewrite your query and find out the answers..
