Can This Query Be Improved?

The query displayed below currently takes approximately 5-6 seconds to run in SQL Query Analyzer. It returns 685 rows. In my opinion, 5 seconds seems way to long, so I am wondering if there is a way to optimize this query. Does anyone have suggestions on what I could do to improve the performance of this query?

DECLARE @.SearchTerm varchar(200)
SET @.SearchTerm = 'john'

SET NOCOUNT ON

SELECT DISTINCT
SalesLead.SalesLeadID,
SalesLead.Prefix,
SalesLead.FirstName,
SalesLead.LastName,
SalesLead.Email,
SalesLead.Phone,
SalesLead.LastContact,
Schools.SchoolID,
Schools.SchoolName,
Schools.City AS 'SchoolCity'

FROM SalesLead
INNER JOIN jnSalesLeadSchool
ON SalesLead.SalesLeadID = jnSalesLeadSchool.SalesLeadID
INNER JOIN Schools
ON jnSalesLeadSchool.SchoolID = Schools.SchoolID
LEFT OUTER JOIN jnSalesLeadDepartment
ON SalesLead.SalesLeadID = jnSalesLeadDepartment.SalesLeadID
LEFT OUTER JOIN Department
ON jnSalesLeadDepartment.DepartmentID = Department.DepartmentID
LEFT OUTER JOIN jnSalesLeadOpportunity
ON SalesLead.SalesLeadID = jnSalesLeadOpportunity.SalesLeadID
LEFT OUTER JOIN AdoptionOpportunity
ON jnSalesLeadOpportunity.OpportunityID = AdoptionOpportunity.AdoptionOpportunityID
LEFT OUTER JOIN CourseNames
ON AdoptionOpportunity.CourseNameID = CourseNames.CourseNameID
LEFT OUTER JOIN SalesLeadNotes
ON SalesLead.SalesLeadID = SalesLeadNotes.SalesLeadID

WHERE
SalesLead.Active = 1
AND (
SalesLead.FirstName + ' ' + SalesLead.LastName LIKE '%' + @.SearchTerm + '%'
OR SalesLead.Address1 LIKE '%' + @.SearchTerm + '%'
OR SalesLead.City LIKE '%' + @.SearchTerm + '%'
OR SalesLead.Email LIKE '%' + @.SearchTerm + '%'
OR SalesLeadNotes.Note LIKE '%' + @.SearchTerm + '%'
OR Schools.SchoolName + ' - ' + Schools.City LIKE '%' + @.SearchTerm + '%'
OR Department.Name LIKE '%' + @.SearchTerm + '%'
OR CourseNames.CourseName LIKE '%' + @.SearchTerm + '%'
OR AdoptionOpportunity.Term LIKE '%' + @.SearchTerm + '%'
OR AdoptionOpportunity.Chances LIKE '%' + @.SearchTerm + '%'
)

ORDER BY SalesLead.LastName

Thanks in advance!
AaronPerhaps the execution plan has a hint. How much has the distinct? Don't know how expensive it really is. It might be an option to rewrite the whole thing to match the exact search-type so there's no OR-left.

Whats the rowcount without the where-clause?|||Creating an index on Saleslead.Active might help a bit. Enabling full text indexing (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/acdata/ac_8_qd_15_74oj.asp) will help a lot, but at a significant cost in disk space and INSERT/UPDATE performance.

-PatP|||According to the execution plan, the DISTINCT is costing 2%, but I need that to filter out the duplicate information that the OUTER joins cause.

The rowcount without the where clause is 15,617.

According to the execution plan, the two biggest costs are:
38% - SORT(Sorting the Input) - ARGUMENT: ORDER BY:(jnSalesLeadSchool.SalesLeadID ASC)

19% - INDEX SEEK(Scanning a particular range of rows from a non-clusted index) - OBJECT: SalesLeadNotes.IX_SalesLeadNotes.SalesLeadID, SEEK: SalesLeadNotes.SalesLeadID = SalesLead.SalesLeadID|||LIKE '%something'??

That's a scan everytime|||I understand that the wildcard matches are probably the biggest problem area, but is there any way around them besides a full text search?|||I was gonna say...

"Drop back and punt"...

Ah the Giants of yesteryear....

how does this do?

AND (
SalesLead.FirstName + ' ' + SalesLead.LastName
+ SalesLead.Address1
+ SalesLead.City
+ SalesLead.Email
+ SalesLeadNotes.Note
+ Schools.SchoolName + ' - ' + Schools.City
+ Department.Name
+ CourseNames.CourseName
+ AdoptionOpportunity.Term
+ AdoptionOpportunity.Chances
LIKE '%' + @.SearchTerm + '%'
)|||I was gonna say...

AND (
SalesLead.FirstName + ' ' + SalesLead.LastName
+ SalesLead.Address1
+ SalesLead.City
+ SalesLead.Email
+ SalesLeadNotes.Note
+ Schools.SchoolName + ' - ' + Schools.City
+ Department.Name
+ CourseNames.CourseName
+ AdoptionOpportunity.Term
+ AdoptionOpportunity.Chances
LIKE '%' + @.SearchTerm + '%'
)|||Brett,
I actually tried exactly that yesterday before going home. Here is the problem: if any of those fields are null (which some are), the entire string will default to NULL - which means rows are not matched. To combat this, I tried using an ISNULL(field, '') on each field while concatenating, but the overhead of the ISNULL cancelled out the gain.|||OK, then punt...

Or simplify the criteria...

or...and this is my last shot before FULLTEXT

DECLARE @.SearchTerm varchar(200)
SET @.SearchTerm = 'john'

SET NOCOUNT ON
SELECT DISTINCT * FROM (
SELECT
x.SalesLeadID,
x.Prefix,
x.FirstName,
x.LastName,
x.Email,
x.Phone,
x.LastContact,
x.SchoolID,
x.SchoolName,
x.City AS 'SchoolCity'

FROM ( SELECT * FROM SalesLead a
INNER JOIN jnSalesLeadSchool b
ON a.SalesLeadID = b.SalesLeadID
INNER JOIN Schools c
ON b.SchoolID = c.SchoolID

WHERE SalesLead.Active = 1
AND ( REPLACE(a.FirstName, @.SearchTerm, '') <> a.FirstName
OR REPLACE(a.LastName, @.SearchTerm, '') <> a.LastName
OR REPLACE(a.Address1, @.SearchTerm, '') <> a.Address1
OR REPLACE(a.City, @.SearchTerm, '') <> a.City
OR REPLACE(a.Email, @.SearchTerm, '') <> a.Email
OR REPLACE(c.SchoolName, @.SearchTerm, '') <> c.SchoolName
OR REPLACE(c.City, @.SearchTerm, '') <> c.City
) AS X
LEFT OUTER JOIN jnSalesLeadDepartment d
ON X.SalesLeadID = d.SalesLeadID
LEFT OUTER JOIN jnSalesLeadOpportunity f
ON X.SalesLeadID = f.SalesLeadID
LEFT OUTER JOIN SalesLeadNotes i
ON X.SalesLeadID = i.SalesLeadID
LEFT OUTER JOIN Department e
ON X.DepartmentID = e.DepartmentID
LEFT OUTER JOIN AdoptionOpportunity g
ON X.OpportunityID = g.AdoptionOpportunityID
LEFT OUTER JOIN CourseNames h
ON g.CourseNameID = h.CourseNameID

WHERE
OR REPLACE(i.Note, @.SearchTerm, '') <> i.Note
OR REPLACE(e.[Name], @.SearchTerm, '') <> e.[Name]
OR REPLACE(h.CourseName, @.SearchTerm, '') <> h.CourseName
OR REPLACE(g.Term, @.SearchTerm, '') <> g.Term
OR REPLACE(g.Chances, @.SearchTerm, '') <> g.Chances
) AS XXX
ORDER BY LastName|||Thanks Brett, but that query takes exactly the same amount of time. I like your idea of using Replace rather than the wildcard comparison, that was clever.

It looks like fulltext is my last resort - are there any rules agains using fulltext searching on columns that contain such a small amount of text (usually less than 100 characters)?|||ow btw: why the order by on a distinct ?|||What you want is really a full-text search. We are beating this mouse bloody when you really want an ox. Byte the bullet and move on!

Can not registre SQL in Enterprise Manager

Hello,
I try to register a remote SQL Server 2000 installed in a W2003, but it
doesn't work. Afer about 5 or 6 seconds, it says: Timeout expired.
In that network , there is not any firewall and port 1433 is open in the
router. What it really surpises me, is that
I can connect via ODBC to any database of that remote SQL Server2000 and
work wuth tables fine !!!
Using the Enterprise Manager from the W2003 server, we have checked
the following:
-Network Configuration button on the General tab
Is TCP/IP enabled?
-In the Connections tab, the Query time-out value is not set too low (600
seconds)
-There is not a maximum concurrent user connections value set
(unlimited).
Also, we can register others remote servers and work fine.
Any idea ?
Thank you very much !
Charles.It's the login timeout you want to try increasing. See my
reply to your post in .connect for steps to do this.

Charles,
Try increasing the login timeout used by Enterprise Manager.
In Enterprise Manager, go to the menu to Tools, then select
Options. Click on the Advanced tab and increase the login
timeout from the default 4 seconds. Try 10 or 15 seconds
instead and see if that helps.
