I have an old app that I'm trying to recode and improve performance.
From the start it makes three seperate calls to a db, checks to see if the record exists, if it doesn't it adds it, then takes the data from all three and inserts it into a final call.
Here is a quick example of the script
Select * from table1 where id = " & tempVariable
If Not RS.EOF Then
strTable1 = RS("SomeRec")
Else
RS.ADDNEW
RS("SomeRec") = tempRec1
RS.UPDATE
RS.Requery
strTable1 = RS("SomeRec")
End If
RS.CLOSE
Select * from table2 where id =2
If Not RS.EOF Then
strTable2 = RS("SomeRec")
Else
RS.ADDNEW
RS("SomeRec") = tempRec2
RS.UPDATE
RS.Requery
strTable2 = RS("SomeRec")
End If
RS.CLOSE
Select * from table3 where id =3
If Not RS.EOF Then
strTable3 = RS("SomeRec")
Else
RS.ADDNEW
RS("SomeRec") = tempRec3
RS.UPDATE
RS.Requery
strTable3 = RS("SomeRec")
End If
RS.CLOSE
I've got a performance issue. Here's in global what the sp (Let's call it SP_A) does. Step 1 Call a different SP (Lets call it SP_B) and store the output in a variable Step 2 SP_B runs a select statement that returns 1 value Step 3 SP_A uses this value as a parameter in a select statement. Step 4 The result of the SP_A is the result of the select statement (744 rows (always))
All tables used in SP_A and SP_B are temp tables. Total performance of SP_A is between 0.090 and 0.140 seconds.
The problem is that this SP is called 180 times from outside SQL server. That means that the total processing time is somewhere between 21 and 25 seconds.
When I move the entire processing to within SQL server I gain only 2 seconds. So I lose 2 seconds in connecting to the database 180 times.
Can someone give me some pointers on where to look for performance wins?
I'm new to programming with the ReportViewer object and this issue has me stumped: it appears if you have some optional parameters in your report, and a way to refresh that report with different parameter values, the report "remembers" parameter values from previous calls to SetParameters() on subsequent renderings of the report. If a parameter is included in a call to ServerReport.SetParameters() on the first rendering, but not included in a subsequent call and the report is re-rendered, the previous value of the parameter (rather than the default value) appears to be used.
Here's a snippet of some test code I wrote within an ASP.NET 2.0 test application:
retVal[paramCount++] = new ReportParameter("Name", txtName.Text);
if (txtAddress.Text != "")
retVal[paramCount++] = new ReportParameter("Address", txtAddress.Text);
if (txtZip.Text != "")
retVal[paramCount++] = new ReportParameter("Zip", txtZip.Text);
return retVal;
}
The test report was written to simply echo back the values of the parameters that are specified. The report definition allows NULL to be specified for the parameters.
The test app was written so if I enter a blank value for Name, Address or Zip, the corresponding parameter does not get created in C# and does not get sent to the report server. If I view the report with all three values (parameters) filled in, I see the parameters echoed back to me in my simple report as expected. If I clear the parameter values the first time the report is rendered, none are sent to the report server and I get no values echoed back in my report, also as expected. I can change the values and click on the View Report button and see the new values for the parameters as expected. However, if I clear any previously-specified parameters and click on View Report, the previously-specified values for the ones that are now cleared are still displayed by the report.
So my question is: once a parameter has been sent to the report, how does one "unsend" it on subsequent refreshes? I know I can create the parameter and set its value to null...but I have a situation here where that can cause errors. It'd be better if I could simply leave out the unspecified parameters and have the report refresh and render as if I were rendering it for the first time.

I am running a query to pull data from 2 tables. However multiple data elements could be attached to one unique ID which when I run the query it repeats causing the entire data set to give inaccurate numbers. How to achieve this:
IS there a way to combine all matching rows in a table so that itoutputs as one row, for example:tblMyStuffUniqueID int IDENTITYParentID intSomeSuch nvarchar(50)SomeSuch2 nvarchar(50)Table data:UniqueID ParentID SomeSuch SomeSuch21 1 Dog Bark2 1 Cat Meow3 3 Cow Moo4 3 Horse Whinnie5 5 Pig OinkDesired query result from Query:SELECT ??? as myText from tblMyStuff WHERE ParentID = 3myText = Cow Moo, Horse WhinnieHelp is appreciated,lq

The users to groups relationship is many-to-many, which is why I created the intermediate table. I would like to return a recordset like: userid, name, groupids 12344, 'Bob', '123,234,345'
If I try to just select groupid from groupadmins: select userid, name, (select groupid from groupadmins where groupadmins.userid = users.userid) as groupids from users
then I'll get an error that a subquery is returning multiple results. Some users are not group admins and those that are may have a single or multiple groups. The only thing I can think of is to select the groupids seperately and use a cursor to loop through the results and build a string with the groupids. Then I would select the string with the rest of the fields that I want for return. Is there a better way to do this?
Hello, I need to generate a report, which should display 4 reports. Two tables and some charts. I have all these reports (I mean the .RDL files) individually. I can render the reports separately. But, now the need is to combine these reports in the one RDL file. Is this possible? If yes, how?
Also, I tried to create a stored procedure, which would call all these 4 SP inturn and provide 4 result sets. I thought of have an RDL by calling only this SP which would give 4 result sets. But infortunately, it gave only the first SP's result set. So, I have to combine the 4 RDL files into one to show on the Reporting Console. Can anyone please help me in this? Help would be grately appreciated.
Thanks a lot. Let me know if the question is not clear.

Hi. I’m having a conceptual problem with tracking sales vs. call center calls. Each record in the fact table represents a call to the call center. In this record are various facts and foreign keys that map to marketing campaigns, etc. The product sold ID is NULL on no sale, and filled in for a sale. When creating MDX to retrieve data by campaign, for example, to track the number of calls for a campaign vs. it’s sales, that works fine (because there’s a column labeled sale that’s either 0 or 1 for the sale and I just sum it). This way I get the conversion percentage of calls to sales.
But when creating MDX to track the product sold, as soon as I do a crossjoin on campaign and products sold, for example, I lose the total calls- the number of calls is the same as the sales (similar results as a SQL join). Am I doing something wrong or is it conceptually impossible to track this type of metric down to the product when there are NULLs in the fact table? I’ve tried converting the nulls to a NONE category, but that doesn’t stop the crossjoin from not giving me the desired results, plus I then have to filter out NONE as a product. Is that why a lot of sample warehouses have a separate sales cube?
I am attempting to see if an application is calling a particular stored proc. i have the Profiler setup to only display the login and it is. I have all items set to display under Stored Procedures, but I can't see names of procedures in the Text Data.
hi all. when i worked with oracle before, it was very common to call a function from inside a s.procedure. now, someone talled me that in sqlserver this is not a best performance approach, and i should try to avoid this. is this true?
My Problem is that I don€™t know really what does a call means.
We got a SQL Standard Edition. Can I install as many instances I want in a Server? How many users can access the Server at the same time?
If I use SQL authentication, and two users use this logging information, how many calls do they made? 2 one per each user (PC) or just 1 one per logging.
If I have a client / server application, and the server access the SQL Server using SQL authentication. Can I have unlimited number of clients?
I'd like to keep state between calls to a UDF (mainly for caching purposes). I can shove an object into the appdomain using SetData and read it using GetData, but that requires the assembly to be set to UNSAFE. I'm confident I can secure the DB and the assembly fairly well, but I like defense in depth, and if there's another way to save state between calls to a UDF, I would prefer those.
Is there another way to store state between calls to a UDF, without putting data into DB tables or using things that will require the assembly to have such a wide permission set?
Suppose my database has 3 table A though C and I need to get the number of records in each. I could do it as individual selects like SELECT 'A' AS 'Table', COUNT(*) AS 'Count' FROM A SELECT 'B' AS 'Table', COUNT(*) AS 'Count' FROM B SELECT 'C' AS 'Table', COUNT(*) AS 'Count' FROM C
or SELECT 'A' AS 'Table', COUNT(*) AS 'Count' FROM A UNION SELECT 'B' AS 'Table', COUNT(*) AS 'Count' FROM B UNION SELECT 'C' AS 'Table', COUNT(*) AS 'Count' FROM C
Is there any problem in unioning statements like these? In reality there were over a hundred tables and the TSQL was generated by looping through SYSOBJECTS. I eventually used the first construct as the XML was simpler to generate.
I need to develope a stored procedure (eventually called by a trigger) that creates a record in an event table for all the descendants of a drawing. There are 3 tables involved as example tables shown below:
DwgTable
DwgID (integer)--drawing record identifier
PrntDwgID (integer)--parent drawing record identifier (a previously defined DwgID from this table)
DwgEventTable
DwgEventID (integer)--record identifier
DwgID (integer)--value from DwgTable
EventID (integer)--value from EventTable
EventTable
EventID There are other fields in two of the tables and only the fields shown in the DwgEventTable, but only the fields shown are required for adding a record in the DwgEventTable for a new event in the EventTable. The problem is identifying all the DwgID's of the descendant of the DwgID where the EventID occurred. There may be 0 to N descendants in 0 to N generations. I need to add a record for the original DwgID and all the descendant DwgID's in the DwgEventTable for the event identified by EventID.
I could do this from the client side, but a better place would be from the server side. I need some clue(s) on how to start coding a recursive stored procedure in SQL Server 2005. From what I have read, you cannot create a managed code procedure that appends or updates records--if managed code can add/modify records then I can do the above with managed code procedure.
