Hi,
I have a stored procedure that runs for approx 5 mins , its developed by our developers.
I need some suggestions that could improve the performance of this SP and probably reduce its time to run, this SP also causes blocking to other processes.
Stored Procedure:

Nearly 650 lines of code and no execution plan, nor any suggestion that you've attempted to fix this yourself?
We're unpaid volunteers and you've been around long enough to know better.
You should at least take the time to identify which parts of the script are problematic. I doubt that it's all bad.
If you haven't even tried to resolve your issue, please don't expect the hard-working volunteers here to waste their time providing links to answers which you could easily have found yourself.

I understand your concern, also I am just looking into it myself, I just needed some quick suggestions like, 1) Recompile the SP 2) Remove usage of TEMPDB etc...not asking for complete explanation and dedication to it. thanks

Its actually taking around 5 mins, I will provide more details soon. thanks

I would start with the parts that are reaching across databases. Here's a few:
select top 1 * from CoreHistory..PRODUCT where PRODUCT_ID = c.PRODUCT_ID order by SESSION_ID desc
select top 1 * from CoreHistory..MEDIA where MEDIA_ID = c.MEDIA_ID order by SESSION_ID desc
select top 1 * from CoreHistory..MEDIA_INDEX where MEDIA_INDEX_ID = c.MEDIA_INDEX_ID order by SESSION_ID desc
select top 1 * from CoreHistory..MEDIA_INDEX_SEGMENT where MEDIA_INDEX_ID = c.MEDIA_INDEX_ID order by SESSION_ID desc
select top 1 * from CoreHistory..M_TRACK where TRACK_ID = c.TRACK_ID order by SESSION_ID desc
select top 1 * from CoreHistory..PHONETIC where PHONETIC_ID = c.PHONETIC_ID order by SESSION_ID desc

Could step through a statement at a time or insert some logging steps to help identify which statements that are taking the most time and tune them as needed.
January 11, 2019 at 6:32 am
Stuff like this is going to kill performance:
convert(int, sessionUpdate.OBJECT_ID / @idRange) = 6
I didn't read every line or go through it all, but a quick scan showed that. I'll bet it's all over the place and similar code smells will be there too.

Perfect thanks guys for your responses, I need some tips like these.

If you run the stored procedure with SET STATISTICS TIME ON you will be able to work out which statement(s) is/are taking up the time.

One other thing I dislike is differed binding. What is that you ask? This is using differed binding: select top 1 * from CoreHistory..PRODUCT where PRODUCT_ID = c.PRODUCT_ID order by SESSION_ID desc. Instead of specifying the schema of the table PRODUCT in the CoreHistory database you have used the .. notation. This will default to dbo except if the user running this query has a different default schema. Unless you need this functionality you really should explicitly specify the schema.
Other than that, I haven't looked through the code as it is long and I am at work so no time at them moment (maybe later or when I get home). If you could post the actual execution plan for the execution of the procedure (as a .sqlplan file), that I would look at quicker than the code at the moment.

Did you mean deferred binding, by any chance?
I definitely agree that it should be avoided unless necessary.

Yikes. Just glanced back through and spotted this:isnull(c.DBAction, '') != ''
That's another performance killer. You have a ton of tuning opportunities here without even looking at execution plans for all these queries. I would also examine whether or not all the manipulation of the data in temp tables is necessary. How much of that can be done in one query (note, I'm not advocating for a single query to do this, just some reduction in the quantity) instead of a hundred separate calls. After fixing the bad code smells and reducing the work, I'd break out the execution plans to understand how the optimizer is treating the resulting queries. However, at this point, too much easy work is available to start sweating execution plans.

I'm also seeing a ton of things like this PARTY_ID > 0 in statements that are creating temp tables. Is that an identity field? If so aren't you basically just selecting the entire table?
