There is few ways to improve performance of sql query. See:
http://www.infoworld.com/article/2628420/database/7-performance-tips-for-faster-sql-queries.html[^]
http://www.developer.com/db/10-ways-to-improve-sql-query-performance.html[^]

At the first look, reducing the numbers of subqueries in WHERE statement might help.

Solution 2

Your query full of sub-queries, even nested.
Remove those sub-queries and replace them with LEFT JOIN (or INNER JOIN where fits better), that will help you...

Can you give me query by removing sub query and apply left join or inner join for above query.

Not really. I do not know your schema, do not know your request, so it is hard to me to directly help you.
You should use Google to find samples (and there are a lot) and implement them for your case...
