I am facing some performance issues in a Stored Procedure. The procedure
needs to return a resultset based on some search criteria. There are around
20 possible search criteria. Below is the SQL query used in my Stored
procedure. Any help to optimize the search will be great:

SELECT LovCode, LovDesc, ParamCode FROM tp_Lov WITH (NOLOCK)

I have a table with 3M rows that contains a varchar(2000) field withvarious keywords. Here is the table structure:PKColumnImageIDFullTextColumnThere is an association table:ImageIDContractIDNow, I want to do a query where the ContractID = x and Contains someword in the FullTextColumn. There is an association table that mapsImages to Contracts - so I can't use the trick of putting the Contractcode in the FullTextColumn.I'm finding that first the FTS service is performing a search on theKeyword (which can take a long time if 100K rows are returned) thenjoining to the association table for the particular contract.Is there anyway to make this faster by telling the FTS service, onlysearch this subset of rows for the keyword based on the contract.Sorry if this sounds convoluted. Appreciate any help you can suggest.Thanks!
Hi, I have Search Critieria which makes use of "LIKE" statement to get records.THis is very simple search just making use of LIKE statment on two Columns of the table.
Example : SELECT ID from tblName WHERE ID LIKE '%PID_01%' AND LID LIKE '%CR_03%'
This works fine and also performace is also good when we have hundreds/thousandsof records. But when records is of lakhs,i feel using LIKE statment will reduce the performance of our search Query.
SO how can we good performance in search ...? I need to optimize my search which result good performace when we have lakhs of records ....?
I have recently taken up performance optimization activity for our database. Can any one suggest a really good source for articles/tutorials/guides etc. on Performance optimization for SQL server 2005.
Does anyone know any good references (web, books etc) about optimizing performance for MSSQL Server 6.5, not seen from a developers perspective but more the admin of the SQL Server?
I`m using a very data comprehensive application and I have the feeling things would run a lot smoother if the database/server was optimized once in a while (like you can do with Access).
our package have design like this, OLEDBSource à Derived Column à Lookup | Matching Records Un Matched Records | | OLEDBCommand OLEDBDestination (Update) (Insert)
and our source & destination table are oracle. when we execute the package the performance is very low and some times its showing like processing ( yellow color) even for 1 hrs .what could be the problem.can any one help us.is there any reason like when we use orcale database this will slow down the performance of package
I am able to get this to work by using nested loops but they are very inefficient and with the size of my tables I cannot afford to use them. There must be a more efficient solution?
Some general rules... (Hope these are clear enough)
- Each person has at least one Initial_Procedure.
- There may be zero, one, or more Procedure_2 for each Initial_Procedure. - If there is more than one Procedure_2 for an Initial_Procedure get the most recent.
- To link Procedure_2 to Initial_Procedure the Initial_Procedure.Completed_DTTM < Procedure_2.Completed_DTTM and Initial_Procedure.Person_ID = Procedure_2.Person_ID
- If there is more than one Initial_Procedure where Initial_Procedure.Completed_DTTM < Procedure_2.Completed_DTTM: Procedure_2.Completed_DTTM Between row 1: Initial_Procedure.Completed_DTTM and row 2: Initial_Procedure.Completed_DTTM --(assuming Initial_Procedure is in order) AND Initial_Procedure.Person_ID = Procedure_2.Person_ID
Some example data.....
Declare @Initial_Procedure table (ID int, Person_ID int, Completed_DTTM datetime) Insert into @Initial_Procedure Select 1, 1, '01/10/2007' union all Select 1, 1, '02/15/2007' union all Select 1, 1, '02/20/2007' union all Select 1, 2, '01/02/2007' union all Select 1, 3, '06/26/2007' union all Select 1, 4, '03/14/2006' union all Select 1, 4, '10/10/2006' union all Select 1, 4, '08/27/2007'
Declare @Procedure_2 table( ID int, Person_ID int, Completed_DTTM datetime) Insert into @Procedure_2 Select 2, 1, '01/09/2007' union all Select 2, 1, '01/15/2007' union all Select 2, 1, '01/16/2007' union all Select 2, 1, '01/17/2007' union all Select 2, 1, '02/19/2007' union all Select 2, 1, '07/25/2007' union all Select 2, 1, '09/02/2007' union all Select 2, 2, '01/01/2007' union all Select 2, 2, '01/14/2007' union all Select 2, 2, '01/20/2007' union all Select 2, 3, '05/04/2007' union all Select 2, 3, '06/27/2007' union all Select 2, 4, '11/06/2006'
Hello,I have a question regarding stored procedure desing that provides theoptimal performance. Let's say we have a table Products that consists ofthree columns: Name, Status, RegistrationTime. All columns are indexed andusers should be able to lookup data by any of the columns. We have two mainoptions to design stored procedures for data retrieval:1. Design separate stored procedures for each search criteria:LookupProductsByName, LookupProductsByStatus, LookupProductsByTime.2. Write a generic stored procedure that will fit any search criteria:CREATE PROCEDURE GetProducts (@Name varchar(20),@Status int = NULL,@FromTime datetime = NULL,@ToTime datetime = NULL)AS BEGINSELECT[Name],[Status],[RegistrationTime]FROM [Products]WHERE [Name]=CASEWHEN @Name<>NULL THEN @NameELSE [Name]ENDAND [Status]=CASEWHEN @Status<>NULL THEN @StatusELSE [Status]ENDAND [RegistrationTime]>=CASEWHEN @FromTimestamp<>NULL THEN @FromTimestampELSE [RegistrationTime]ENDAND [RegistrationTime]<=CASEWHEN @ToTimestamp<>NULL THEN @ToTimestampELSE [RegistrationTime]ENDORDER BY [RegistrationTime]END;The second option is very attractive, because it is obviously easier tomaintain such code. However, I am a little concerned about performance ofsuch stored procedure. It is not possible to foresee what index should beused, index can only be selected each during procedure execution, becausesearch criteria can include either Name, Status or RegistrationTime. Will itmake this SP inefficient? Or perormance difference in such case is not big(if any) and we should choose the second option because of its significantcode reduction?Thanks in advanceVagif AbilovJoin Bytes!
Would any of you give me any ideas for how could we optimize the report on data mining models? (as we know, for the data mining report, we have to select the mining model and the case table)
Hope it is clear for your advices and help.
Thanks a lot in advance and I am looking forward to hearing from you shortly.
How to optimize the following Stored procedure running on MSSQL server 2000 sp4 :
CREATE PROCEDURE proc1 @Franchise ObjectId , @dtmStart DATETIME , @dtmEnd DATETIME AS BEGIN

Hi, Can anyone help me optimize the SELECT statement in the 3rd step? I am actually writing a monthly report. So for each employee (500 employees) in a row, his attendance totals for all days in a month are displayed. The problem is that in the 3rd step, there are actually 31 SELECT statements which are assigned to 31 variables. After I assign these variable, I insert them in a Table (4th step) and display it. The troublesome part is the 3rd step. As there are 500 employees, then 500x31 times the variables are assigned and inserted in the table. This is taking more than 4 minutes which I know is not required :). Can anyone help me optimize the SELECT statements I have in the 3rd step or give a better suggestion. DECLARE @EmpID, @DateFrom, @Total1 .... // Declaring different variables SELECT @DateFrom = // Set to start of any month e.g. 2007-06-01 ...... 1st Loop (condition -- Get all employees, working fine) BEGIN SELECT @EmpID = // Get EmployeeID ...... 2nd SELECT @Total1 = SUM (Abences) ...... 3rd FROM Attendance WHERE employee_id_fk = @EmpID (from 2nd step) AND Date_Absent = DATEADD ("day", 0, Convert (varchar, @DateFrom)) (from 1st step) SELECT @Total2 ........................... same as above SELECT @Total3 ........................... same as above INSERT IN @TABLE (@EmpID, @Total1, ...... @Total31) ...... 4th Iterate (condition) to next employee ...... 5th END It's only the loop which consumes the 4 minutes. If I can somehow optimize this part, I will be most satisfied. Thanks for anyone helping me....
Trying to optimize a query, and having problems interpreting the data. We have a query that queries 5 tables with 4 INNER JOINS. When I use INNER HASH JOIN, this is the result:
(Using SQL Programmer)
SQL Server Execution Times: CPU time = 40 ms, elapsed time = 80 ms.
Now, when timing the code execution on my ASP page, it's "faster" not using the HASH. Using HASH, there are a few Hash Match/Inner Joins reported in the Execution Plan. Not using HASH, there are Bookmark Lookups/Nested Loops.
My question is which is better to "see": Boomark Lookups/Nested Loops or Hash Match/Inner Joins for the CPU/Server?
IS there any way to rewrite this Query in optimized way?

How can I optimazed my query. Since my DB is more then 1 mln it takes a while to do all those join? select * FROM EEMaster eem JOIN NHistory nh ON eem.SNumber = nh.SNumber OR eem.OldNumber = nh.SNumber OR eem.CID = (Replicate ('0',12-len( nh.SNumber))+ nh.SNumber )
I work on tables containing 10 million plus records. What are the general steps needed to ensure that my queries run faster? I know a few: - The join fields should be indexed -Selecting only needed fields -Using CTE or derived tables as much as I can -Using good table reference eg select a.x , b.y from TableA a inner join TableB b on a.id = b.id
I will be happy if somebody could share or add more to my list.

I am writing a query which will display employee details who is handling maximum number of projects. Here I am joining 2 tables. one is LUP_EmpProject, which contain employee id and project id and project date, in this table I have used a composite primary key of employee id, project id and project date. The other table is
EmployeeDetails which contain employee names and employee id.
I want to display the details of the employee who is handling maximum projects. Below given is the code which is working fine. But the query is taking time to execute it. Any body know how to optimize the code so that I can get the result quickly.
Code Snippet SELECT EmployeeDetails.FirstName+' '+EmployeeDetails.LastName AS EmpName, COUNT(LUP_EmpProject.Empid) AS Number_Of_Projects FROM LUP_EmpProject INNER JOIN EmployeeDetails ON LUP_EmpProject.Empid=EmployeeDetails.Empid GROUP BY EmployeeDetails.FirstName+' '+EmployeeDetails.LastName, LUP_EmpProject.Empid HAVING COUNT(LUP_EmpProject.Empid)>0 AND COUNT(LUP_EmpProject.Empid)=(SELECT MAX(Number_Of_Projects) FROM (SELECT COUNT(LUP_EmpProject.Empid) Number_Of_Projects FROM LUP_EmpProject GROUP BY LUP_EmpProject.Empid)AS sub)

where (f1.Grouptitle = @GroupPFR and f1.MetricName = '$ Products')
and ( f2.Grouptitle = @GroupRevenue and f2.MetricName = 'Net Revenue')
group by f1.weekdate
There are many calculations like this in my procedure. and It takes like 3 min to run whole procedure now as I am doing group by.. So In Execution plan it show me that 60% of the query time is take n by SORT operation.. can any one give me any other option to do this.

I have a small tricky problem here...need help of all you experts.
Let me explain in detail. I have three tables
1. Emp Table: Columns-> EMPID and DeptID 2. Dept Table: Columns-> DeptName and DeptID 3. Team table : Columns -> Date, EmpID1, EmpID2, DeptNo.
There is a stored procedure which runs every day, and for "EVERY" deptID that exists in the dept table, selects two employee from emp table and puts them in the team table. Now assuming that there are several thousands of departments in the dept table, the amount of data entered in Team table is tremendous every day.
If I continue to run the stored proc for 1 month, the team table will have lots of rows in it and I have to retain all the records.
The real problem is when I want to retrive data for a employee(empid1 or empid2) from Team table and view the related details like date, deptno and empid1 or empid2 from emp table. HOw do we optimise the data retrieval and storage for the table Team. I cannot use partitions as I have SQL server 2005 standard edition.
Please help me to optimize the query and data retrieval time from Team table.
Hi - I'm short of SQL experience and hacking my way through creating a simple search feature for a personal project. I would be very grateful if anyone could help me out with writing a stored procedure. Problem: I have two tables with three columns indexed for full-text search. So far I have been able to successfully execute the following query returning matching row ids: dbo.Search_Articles @searchText varchar(150) AS SELECT ArticleID FROM articles WHERE CONTAINS(Description, @searchText) OR CONTAINS(Title, @searchText) UNION SELECT ArticleID FROM article_pages WHERE CONTAINS(Text, @searchText); RETURN This returns the ArticleID for any articles or article_pages records where there is a text match. I ultimately need the stored procedure to return all columns from the articles table for matches and not just the StoryID. Seems like maybe I should try using some kind of JOIN on the result of the UNION above and the articles table? But I have so far been unable to figure out how to do this as I can't seem to declare a name for the result table of the UNION above. Perhaps there is another more eloquent solution? Thanks! Peter
I need help in optimizing this query. The major time takes in calling a remote database. Thanks in advance.ALTER PROCEDURE dbo.myAccountGetCallLogsTest@directorynumber as varchar(10),@CallType as tinyint ASdeclare @dt as intSELECT TOP 1 @dt=datediff(day,C.EstablishDate,getdate())FROM ALBHM01CGSERVER.Core.dbo.Customer C INNER JOIN ALBHM01CGSERVER.Core.dbo.UsgSvc U ON C.CustID = U.CustIDWHERE (U.ServiceNumber = @directoryNumber)ORDER BY C.EstablishDate DESCIF @dt>90select DN as Number, Remote_DN as [Remote Number], City, StartTime as [Start Time], EndTime as [End Time] from vw_Call_Logs where DN = '1' + @directoryNumber and call_type = @CallType and datediff(day,starttime,getdate())<90order by starttime descELSE select DN as Number, Remote_DN as [Remote Number], City, StartTime as [Start Time], EndTime as [End Time] from vw_Call_Logs where DN = '1' + @directoryNumber and call_type = @CallType and datediff(day,starttime,getdate())< @dtorder by starttime desc
select count(a.callid) from tbl1 as a inner join tbl2 as b on a.calldefid=b.calldefid where a.programid=175
select count(a.callid) from tbl1 as a inner join tbl2 as b on a.calldefid=b.calldefid where b.programid=175
callid - pk on tbl1 calldefid - nonclustered index on both tbl1 and tbl2 programid - nonclustered index on both tbl1 and tbl2 tbl2 is the smaller table
from my understanding, the second query will run faster because you reduce the records in the smaller table, then join to the larger table (tbl1).
but can you explain to me why limiting the rows on tbl1 first, then joining to tbl2 would take longer?
