The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Query taking exceptionally long time

Asked by Marcusw in MS SQL Server

Tags: take, time, why

could somebody give me some ideas as to what is wrong with this query

select count(*) TOTAL ,
sum(case when GotContact = 1 then 1 else 0 end) GotContact,
sum(case when GotPhone = 1 then 1 else 0 end) GotTel,
sum(CASE WHEN GotEmail = 1 THEN 1 ELSE 0 END) GotEmail
from Data..tblCompany
WHERE (ID in (select ID from tbl1 where Code in (f222','e896','w834'))
or SIC in ('74111') (=)

it does not seem to run, i've left it for over 30 min but it just keeps running

if i run the same code without the line
or SIC in ('74111')
it runs in 1.5 seconds

or if i remove
(ID in (select ID from tbl1 where Code in (f222','e896','w834')))
it runs in about 5 seconds.

it is counting a lot of data
tblCompany has around 3 million records and tbl1 has around 50 million.

tblCompany has a clustered index on its ID and tbl1 has a clusterd index on code.

i have no ideas why the 2 together take so long
