Can any one provide me details of the parameters to be monitored in sql server 2005
Currently i am monitoring
SQLServer : Buffer Manager : Buffer Cache Hit Ratio
SQLServer : Databases : Log Flushes / Sec
SQLServer : Databases: Transactions / Sec
SQLServer : Access Methods : Page Splits / Sec.....
1) Please provide if any other relevant parameters to be monitored by perfmon.
2) Which are the most essential parameters to be monitored.
3) Is there any query or trace that will provide me performance details in SQL.
4) Can i have a query that get me the most resource consuming process or query in sql server.
5) wht parameters do i need to monitor on weekly and monthly basis for sql server 2005.
It would be very helpful if you guys could provide me help on these.
Thanks in advance
I have a user defined function which has 5 parametes to pass, now while running the Table Valued Function using hardcoded parametes value its taking only 10 seconds , but while running the UDF by declaring the parametes value and assigned them value its taking more than 3 minutes.
here is the example
First case
select * from UDF_Test('A',76,'C',987,''X')
This one taking only 10 minutes to run.
Second case
Declare @P1 varchar,
@P2 Int, @P3 varchar, @P4 int, @P5 varchar
SET @P1 = 'A'
@P2= 76
@P3='C' @P4 = 987 @P5='X'
Select * from TVF_Test(@P1,@P2,@P3,@P4,@P5) as test where test.column1=@P1
I have run into a very odd issue with the performance of one of our stored procedures. The SP seems to perform very poorly if I embed the parameters directly into the query. If I declare local variables to hold the parameter values, the SP runs a lot faster. This stored procedure takes about 26 seconds: CREATE PROCEDURE dbo.jk_ReportData_Get @startDate datetime, @endDate datetime, @entityID int, @reportID int AS select sum(amount_mtd) Amount, account_id, entity_id from data where account_id in (select paramvalue from cellparameter where cell_id in (select cell_id from report_reportsection rrs inner join reportsection rs on rrs.reportsection_id = rs.id inner join reportsection_cell rsc on rs.id = rsc.reportsection_id where report_id = @reportID)) and thedate between @startDate and @endDate and data.entity_id = @entityID group by account_id, entity_id GO
When I change it to the following, it takes less than one second: CREATE PROCEDURE dbo.jk_ReportData_Get @temp1 smalldatetime, @temp2 smalldatetime, @temp3 int, @temp4 intAS declare @startDate datetimeset @startDate = @temp1declare @endDate datetimeset @endDate = @temp2declare @entityID intset @entityID = @temp3 declare @reportID intset @reportID = @temp4 select sum(amount_mtd) Amount, account_id, entity_id from data where account_id in (select paramvalue from cellparameter where cell_id in (select cell_id from report_reportsection rrs inner join reportsection rs on rrs.reportsection_id = rs.id inner join reportsection_cell rsc on rs.id = rsc.reportsection_id where report_id = @reportID)) and thedate between @startDate and @endDate and data.entity_id = @entityID group by account_id, entity_id GO Can anyone explain this please??? :) Notice it is the same query in both cases. The only difference is in the parameters...
Hi all, I have a report which uses two different datasets. The first one is used to get the required data and the second one is to get the customer name to be used in a parameter. I had a major performance issue with the report as the first dataset is very complex. And after I did a lot of SQL tuning to the first dataset, it is now working fine with an acceptable performance. The problem now is when I tried to add a condition in this dataset to be used by the parameter like WHERE CUSTOMER_NAME IN (@CustName ) The performance of the report is getting very bad again and the report can take more than 15 min. to get the result. The second dataset is a simple query that is used to get the customer name from the customer table so I don€™t think it is the problem. Any ideas? Do you think it has anything to do with the SSRS parameters. Thanks all.
I have a query with 9 parameters that run as follows (approximate timing): 1. Using prepared statement: 1,7 sec 2. Re-using the same statement: 1,7 sec 3. Using prepared statement, no parameters (the params are hardcoded): 20 ms 4. Using statement+resultset+rs.getFirst: 20 ms 5. from inside SQL analyzer: instantly
So, I observe a problem when using parameters. Do I miss something, do I have to do something?
If the actual query may help, I will post it promptly.
Hi, I am interested if anyone else has come across performance problems with the SQL Server linked servers to SQL Server. I suspect that the OLE DB Provider that I am using perhaps has some performance issues when passed parameters.
I have set the dynamic paramters option on, and use collation compatible.
Hi all, From the "How to Call a Parameterized Stored Procedure by Using ADO.NET and Visual Basic.NET" in http://support.microsft.com/kb/308049, I copied the following code to a project "pubsTestProc1.vb" of my VB 2005 Express Windows Application:

Dim testCMD As SqlCommand = New SqlCommand("TestProcedure", PubsConn)
testCMD.CommandType = CommandType.StoredProcedure
Dim RetValue As SqlParameter = testCMD.Parameters.Add("RetValue", SqlDbType.Int)
Console.WriteLine("Number of Records: " & (NumTitles.Value))
End Sub
End Class
////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// The original article uses the code statements in pink for the Console Applcation of VB.NET. I do not know how to print out the output of ("Book Titles for this Author:"), ("{0}", myReader.GetString(2)), ("Return Value: " & (RetValue.Value)) and ("Number of Records: " & (NumTitles.Value)) in the Windows Application Form1 of my VB 2005 Express. Please help and advise.
I have a SSRS report with four parameters,and I want to be able to enter information for two of the parameters and run the report opposed to all four of them. However, when I select allow blanks and only select the parameters that I want to run the report by, the report come back blank..Essentially, I want to be able to the run report by different parameters without having to enter information for all parameters at the same time.
Hello Everyone,I have a very complex performance issue with our production database.Here's the scenario. We have a production webserver server and adevelopment web server. Both are running SQL Server 2000.I encounted various performance issues with the production server with aparticular query. It would take approximately 22 seconds to return 100rows, thats about 0.22 seconds per row. Note: I ran the query in singleuser mode. So I tested the query on the Development server by taking abackup (.dmp) of the database and moving it onto the dev server. I ranthe same query and found that it ran in less than a second.I took a look at the query execution plan and I found that they we'rethe exact same in both cases.Then I took a look at the various index's, and again I found nodifferences in the table indices.If both databases are identical, I'm assumeing that the issue is relatedto some external hardware issue like: disk space, memory etc. Or couldit be OS software related issues, like service packs, SQL Serverconfiguations etc.Here's what I've done to rule out some obvious hardware issues on theprod server:1. Moved all extraneous files to a secondary harddrive to free up spaceon the primary harddrive. There is 55gb's of free space on the disk.2. Applied SQL Server SP4 service packs3. Defragmented the primary harddrive4. Applied all Windows Server 2003 updatesHere is the prod servers system specs:2x Intel Xeon 2.67GHZTotal Physical Memory 2GB, Available Physical Memory 815MBWindows Server 2003 SE /w SP1Here is the dev serers system specs:2x Intel Xeon 2.80GHz2GB DDR2-SDRAMWindows Server 2003 SE /w SP1I'm not sure what else to do, the query performance is an order ofmagnitude difference and I can't explain it. To me its is a hardware oroperating system related issue.Any Ideas would help me greatly!Thanks,Brian T*** Sent via Developersdex http://www.developersdex.com ***
Hi, I have an app in C# that executes a query using SQLCommand and parameters and is taking too much time to execute.
I open a SQLProfiler and this is what I have :
exec sp_executesql N' SELECT TranDateTime ... WHERE CustomerId = @CustomerId', N'@CustomerId nvarchar(4000)', @CustomerId = N'11111
I ran the same query directly from Query Analyzer and take the same amount of time to execute (about 8 seconds)
I decided to take the parameters out and concatenate the value and it takes less than 2 second to execute.
Here it comes the first question... Why does using parameters takes way too much time more than not using parameters?
Then, I decided to move the query to a Stored Procedure and it executes in a snap too. The only problem I have using a SP is that the query can receive more than 1 parameter and up to 5 parameters, which is easy to build in the application but not in the SP
I usually do it something like (@CustomerId is null or CustomerId = @CustomerId) but it generate a table scan and with a table with a few mills of records is not a good idea to have such scan.
Is there a way to handle "dynamic parameters" in a efficient way???
When I query the ReportServices WS and scan the parameter dependencies for SalesRep it says there are four dependencies: FromDate, ToDate, DivisionalOffice and Manager!!!
If I change "dsSalesRep" to use "DivisionalOffice.Value" the ReportingServices WS parameter dependency scan returns only one dependency for "SalesRep" parameter!!!( This is the correct behavior )
Has anybody seen this behavior and more importantly, is there a work around?

Hello all, Given: string commandText = "Categories_Delete";SqlCommand myCommand = new SqlCommand(commandText, connection);myCommand.CommandType = CommandType.StoredProcedure; Is there a reason NOT to use myCommand.Parameters.AddWithValue("@CategoryID",CategoryID); I'd prefer to use that over myCommand.Parameters.Add("@CategoryID", SqlDbType.Int, 4).Value = CategoryID; as I have these functions being created dynamically and hope to get away from a big lookup to try to convert System.Types into SqlDbTypes. [shudder] It seems that ADO.NET makes an implicit conversion to the valid type. If this is correct then I can move on fat dumb and happy. Anyone have any good insight? Thanks,

Hi, The following code doesnt work. I am trying to get data from a table according to a querystring. Id like the data in the columns 'hello' and 'hello2' to be meta name and content. But it says
The name 'hello' does not exist in the current context
command.CommandText = "SELECT hello, hello2 FROM table WHERE ID=@ID"; command.Parameters.AddWithValue("@ID", Request.QueryString["ID"]); command.ExecuteNonQuery(); HtmlMeta meta = new HtmlMeta(); meta.Name = "Description"; meta.Content = "first" + hello; Page.Title = "first" + hello2; Header.Controls.Add(meta);
I need to add parameters to my SQL string, like Where [EndDate] >= @HStart AND [EndDate] <= @HEnd, I tried to Dim variables but it caused an error. Can anyone help me with this?
Thank You,
Sub BindDataCurrent() Where [EndDate] >= @HStart AND [EndDate] <= @HEnd" 'MyCommand.Parameters.Add("@HStart", SqlDbType.VarChar, 80).Value = HistoryStartText.Text 'MyCommand.Parameters.Add("@HEnd", SqlDbType.VarChar, 80).Value = HistoryEndText.Text ConnectStr = ConfigurationSettings.AppSettings("ConnectStr") Dim MyConnection As SqlConnection = New SqlConnection(ConnectStr) MyConnection = New SqlConnection(ConnectStr)
Dim SQL As String = "Select [Campaign_ID], [Campaign Type], [Campaign Date], [EndDate],[Comment] FROM tblCampaignTracking Where [EndDate] >= @HStart AND [EndDate] <= @HEnd" Dim DA As SqlDataAdapter = New SqlDataAdapter(SQL, MyConnection) Dim DS As New DataSet DA.Fill(DS, "tblCampaigns") MyEditDataGridCurrent.DataSource = DS.Tables("tblCampaigns").DefaultView MyEditDataGridCurrent.DataBind() End Sub
I'm having a bit of trouble with SQL Parameters. I can't seem to define the type when creating the parameters.
Here's what I've done:
I have a function that processes my request and returns a datatable:
Public Function Grab_Data(querystring asn string, params() as SqlParameter) as DataTable ... dims all the necessary variables Try ...creates the connection and command Dim p as SqlParameter For each p in params p = command.parameters.add(p) p.direction = parameterdirection.input Next ...opens connection, creates dataset and fills it Finall ....disposes connection and command End Try Return datatable End Function
I call this function by: ...dim the necessary variables querystring = "SELECT * FROM Tbl_Users WHERE Joined>=@date" dataTable = Grab_Data(querystring, New SQLParameter("@date", DateTime.Today))
My code works fine and I get the results that I want, but no where in my code is the type of the parameter defined.
I tried calling the function like: Grab_Data(querystring, New SQLParameter("@date", SQLDBType.DateTime, DateTime.Today))
But when I do this, I get an error saying that no value is assigned to @date.
Can anyone tell me what I need to modify so that I can pass the type of the parameter to the function?
The reason why I am not explicity defining the parameters in the function is because I can reusing the function numerous times throughout my code. So some calls have three parameters passed to it and some and none.
Hi all, I know I could do something like this in SQL:
select customers.name from customers where customers.name = request.form("txtname")
but my question is, can I have a user pick the operator (such as =,>,<,>=,<=) from a dropdown box and pass it the the sql statement as a parameter such as:
select customers.name from customers where customers.name request.form("txtoperator") request.form("txtname")
Hi all, I am using classic ASP and SQL Server 2005. Can I use parameters like @whatever in my asp code or are they for stored procedures exclusively? I am trying to change the output of a request.form into a paramater so I can prevent SQL injection I am aware of using trim to counter this but I wasn't sure of the best practice.
I want to build a spaceship with ligthspeed capabilities and I don't even know what a wrench is.
I have a set of date parameters in reporting services which are defaulted to 3/01/08. How can I make them to the current month so that six months from now they are not still reading 3/01/08
ALTER PROCEDURE dbo.SkillSearch ( @skillname char(255) ) AS SET NOCOUNT ON SELECT * FROM Skill WHERE SkillName LIKE @skillname
However, when I run dbo.skillsearch 'ph%'
I get an empty set, while dbo.skillsearch 'php' returns the results expected.
I am therefore assuming that I can't use a parameter for a LIKE clause with any wildcards?
Is there any way around this other than manually building the SQL statement in the SP and then executing it? I'd obviously prefer to not have to do it that way for all the SQL Injections and related reasons.
Wouldn't this also kill my query optimization benefits, manually building the statement each time?
I am trying to use the URL to pass a parameter to a report. I have tried several ways to make this happen with no effect. My report is using a sproc that has a int parameter. I have tried make a list of partial parameters and passing the parameter I want through the URL. I hide the prompt. I put NULLs and Blanks allowed. I have created a linked report then hid the prompt. I used parameters=false instruction. Here is the basic URL http://reportsrv/Reports/Pages/Report.aspx?ItemPath=%2fActiveTasks%2fProject+Details&rs:Command=Render&ProjectID=56.
hi i need to know what's the syntax in reporting services query in a where statement to get values where comment card name like '%'&@RestaurantName&'%'. This syntax is giving me an error. i need to get the rows where the comment card name contains the restaurant name got from the parameter. can anyone give me the right syntax please?
I have a table of 25-30 million properties, from which are retrieved~150 centered on a point, based on the parameters -- coordinates,property type and date of transaction. There's an SP (also implementedas a function returning a table) to return the desired records.This look-up takes the most time in the C# program that calls it, andshould be optimized. It was suggested that instead of having an SP onthe server, each time the program should create an SP that is the same,however without any parameters -- with the values hard-coded. Thenexecute it, and drop it. This way, the execution plan will becustomized for the specific parameters. I tried it and it turns outthe suggested method is noticeably faster, even compared to recompilingan SP every time. I was wondering if there is a way to get equivalentperformance out of an SP or UDF that has parameters, or is thisapproach necessarily going to be less optimized than hard-codednon-parameters.Thanks,Jim
i am new to ssrs and am trying to generate a report with 4 parameters. 2 of which are dates. The other 2 are drop downlists. Now the report works fine when i enter all 4 parameters. But in some cases i want to leave one of the parameters unentered . It doesnt all me to do that. Gives a error saying i need to enter the parameter. How do u get aroud this issue ?
I have seperate dataset for this parameters list and am using a where clause in my main query.
Hi, I'm trying to generate a report on a DMX query I have created and I would like to pass a parameter into a DMX query containing an OPENQUERY statement. Currently I just do the following:
...OPENQUERY([data source],'SELECT ''@CompanyName'' AS [CompanyName]')...
It does not pass the parameter through though... my query always returns no results! Could anyone help please? Thanks!
