I have a complex SQL Server query that needs a performance improvement. The query is the return of a function (ie, the function returns the query statement). I think that performance improvements on this query should be: indexes to be created on tables involved and create one or more indexed views (I know there are limitations, specifications and commands to be performed on the database for this, so if indexed view is to be done on this project, all these items need to be specified as well.)
The file for this query is attached.
The best description of the steps that are intended to be performed (as long as the price is good as well) wins this project. (I don´t need the solution on your description, just the prove that "you know what you are talking about" :) ).
Thanks!
Hello,
As an expert in SQL, i am very much interested to optimize your query. I have checked your attached function and it is tough to understand the query this way. Can you please send me the generated query from this function?
Most of the time Index View is not possible in an existing database as it needs much changes. So i would like to avoid indexed view. Indexing in the tables might do the thing. How many records are there in the related tables, how much time it is taking currently and how much time you are expecting after optimization? Please let me know more detail and also the generated query.
Thanks

Hi
How are you?

I am sure I can deliver high quality product
Please consider working with me.
I will do my best.
Thanks.
I have 6 year of experience in database development so i can do this as soon as possible. I have hands on experience in sql server, performance tuning, and database structure. I am goo d in DBMS.
I will:
[1] meticulously study the execution plan of your query and optimize the part that is consuming the most time in query execution.
[2] break the query in small pieces and examine the execution plan / time of each separate piece (divide and conquer approach)
[3] investigate the possibility of incorporating window functions in the query
[4] examine if parameter sniffing comes into play resulting in a non optimal query execution plan
To verify my expertise on SQL Server you can review my Stack Overflow profile (search for user Giorgos Betsos).
You dont see any reviews in here as i am new to join the site. But i am not new to tuning SQL queries. I wrote so many complex sql queries and tuned very big queries.
