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?
How can I find calls which do not exist in stored procedures and functions?We have many stored procedures, sometimes a stored procedure or function which is called does not exist. Is there a query/script or something that I can identify which stored procedures do not 'work' and which procedure/ function they are calling?I am searching for stored procedures and functions which are still called, but do not exist in the current database.
View 7 Replies View RelatedI created a Switch statement below that surprisingly doesn't throw any errors and some of it actually works. The problem is that the function calls in the 3rd and 4th sections of it below (in bold) are not working.
=switch(HASONEVALUE('s1JudgeIds'[JudgeName]),

SELECT MAX(ID)
FROM [LinkedServer].[Database].dbo.[TableName] (NOLOCK)

The above SQL Script ran successfully up to yesterday. But today its throws the below error message.
Remote table-valued function calls are not allowed.
Now i have modified the SQL script as follows
SELECT MAX(ID)
FROM [LinkedServer].[Database].dbo.[TableName] WITH (NOLOCK)

I want to know how the 1st SQL script runs successfully up to yesterday.

I am trying to figure out what the equivalent of functions is in SQL Server. I mean, does a Stored Procedure in SQL Server replace a module in Access? Can you declare different functions in SQL Server like you can in Access?
Thanks for your help.

Hi, l've created an function [GSM].[KPIAging], and test it in studio by substitule declare value, i.e.
DECLARE @sCellName VARCHAR(8)
DECLARE @dDate DATETIME
SET @sCellName = "CELL1M_1"
SET @dDate = CAST('06/Jun/2006' AS DATETIME)
EXEC GSM.KPIAging @sCellName, 'CSSR', @dDate
It work fine and return the desired result, but when l used this function in SQL,
SELECT DATEKEY, CELLREGIONKEY, CELL_NAME, CELL_ID, CSSR, GSM.KPIAging(Cell_Name, 'CSSR', @dDate)
FROM GSM.GSMCellDaily_vw
WHERE CSSR BETWEEN 0 AND 85
AND FULLDATE = @dDate
AND CM_SERV > 30
AND (TCH_TRAFFIC > 2 AND TCH_SEIZURES_ATTS > 30)
I got the following error, i.e.

Does anyone have any idea on this, and what's the workaround for this?
Thanks you!

Hi, all
I'm using Sql server 2000
I want to make select statement dynamically and return table using function.
in sp, I've done this but, in function I don't know how to do so.
(I have to create as function since our existing API..)
Following is my tials...
1.
alter Function fnTest
( @fromTime datetime, @toTime datetime)
RETURNS Table
AS
RETURN Exec spTest @from, @to
GO
Yes, it give syntax error..
2. So, I found the following
From Sql Server Books Online, Remark section of CREATE FUNCTION page of Transact-SQL Reference , it says following..
"The following statements are allowed in the body of a multi-statement function. Statements not in this list are not allowed in the body of a function: "
.....
* EXECUTE statements calling an extended stored procedures.
So, I tried.
alter Function fnTest
( @fromTime datetime, @toTime datetime)
RETURNS Table
AS
RETURN Exec master..xp_msver
GO
It doesn't work... syntax err...
Here I have quick question.. How to execute statements calling an extended stored procedures. any examples?
Now, I'm stuck.. how can I create dynamic select statement using function?
I want to know if it's possible or not..
I have this function called fn_GetTimedKey() when I run it in my SQL2005 environment it works fine.
When I run it in my SQL2008R2 environment I get the error:
Only functions and some extended stored procedures can be executed from within a function.
The SQL2008R2 server is new. What can I look for?
Here's the code for the function:
BEGIN
DECLARE @v_Key CHAR(12)
EXEC master..xp_usg_gettimedkey_VAL @v_Key OUTPUT
RETURN @v_Key
END
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?
Thank you,
Richard
Hi group,
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?
If you like I can add the SP's
Regards,
Sander
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
INSERT INTO Table4 (Table1, Table2, Table3) VALUES ('" & strTable1 & "', '" & strTable2 & "', '" & strTable3 & "'
These is probably an easy solution however I don't know where to start. Any help or ideas will be greatly appreciated.
Thanks

Hi,
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?
Thanks,
Alex
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.
Any Suggestions?
I am running the code below in a sql job. Exec (@SQL) errors every time but after 4 failures the job fails instead of trying @MaxRetries times. Any idea on why this is happening?

SELECT @error_value = 0
Exec (@SQL)
SELECT @error_value = @@ERROR

I have several SSIS Packages which are called by few different applications. I need to make packages Mutually Exclusive, so that If one is running; calls to any other Package should be put on wait till the running one has finished its execution.
What are the best ways to do this ?
I would sincerely appreciate inputs in this.
I've got a huge inefficiency in my code that I'm trying to fix. I’m coding in VB.NET using ASP.NET and an MSSQL 2000 server.
I’m working in a temporary table that has an identical layout as another, non-temporary table in my database. Once I get the temp table how I want it, I need to insert everything from that table into my main table. Before I can do that, however, I need to delete all the records in the main table with certain fields that match a record’s fields in the temporary table.
Right now, I have a method that builds one delete statement per record in the temporary table and then runs those statements on the main table. Since I’m dealing with the order of 50,000 records (at least) here, building and sending those statements to the server takes forever.
Is there a way I can accomplish the same thing without building and sending such a huge SQL call to the server? If so, how would I go about doing that?
Thanks in advance for whatever help you can give,

I would like to make inner join with results from different exec %procedureName% calls.
thanks.
is it true that I will not be able to use the returned value from an sp that is called on every row from an oledb command transformation? I see all kinds of complaints on the web but cant determine if this would be a waste of time. I'd like to append the returned value (which is calculated and cannot be joined in the buffer) to the data on its way out of the transformation.

I am using internal activation on a queue to process the messages, should an error be encountered I call stored procedure A in the same database to log the error. Part of the processing in stored procedure A is a call to stored procedure B in another database (on the same server), however I have not been able to get this call to B to work. Currently I get the error "The server principal XXXXXX is not able to access the database YYYYYYY under the current security context".
I have tried various combinations (too many to remember) of database owners, roles and permissions as well as EXECUTE AS on both A and B and the Queue but none seem to work. Can anyone give me simple example of a setup which would allow this cross database call to work?
Thanks

I am wondering if it is at all possible to keep an object in memory between calls to a SqlFunction or SqlProcedure.
Every time a row is inserted in to a table, i need to do some processing on the data. The processing becomes many times faster if I can do some preprocessing (the preprocessing is independent of the data inserted into the table). So basically, I want to save the result of the preprocessing, only do it one time, and save the result in a object in memory. Is this at all possible?

I'm having a terrible time trying to figure out how to do this, does anyone have experience?
My code works fine in the report viewer, but all I get from the deployment is #Error symbols. I've added my custom dll file to the config file and gave it full trust, as well as the URL of the web service I'm calling. I've even modified the rest of the codegroups within the file to FullTrust just in case.
I've also added the [assembly: AllowPartiallyTrustedCallers] to the AssemblyInfo class, and [WebPermission(SecurityAction.Assert)] to the constructor of my custom assembly no avail.
I'm at a complete loss now as to why my deployment cannot run this code. As far as debugging goes, Visual Studio is not located on the reporting server, nor is it an option to have it put there. I've been able to run the code with the web service lines commented out, but as soon as I put even the webservice.Credentials = CredentialCache.DefaultCredentials in I'm greeted with the nice and calming #Error.
Any suggestions?
Hi,
I want to retrieve some parameter values from Reporting Services using GetReportParameters from
Microsoft.SqlServer.ReportingServices.ReportService2005.
It works fine unless the parameter types are date/time. In such a case it seems as if the format of the parameter depends on the ReportServices installation:
Example:
On a German installation the date/time format is "dd.mm.yyyy" but on an English installation the format is different (mm/dd/yyyy) (and of course the time part is also different).
Is there a way to determine the format to be expected? (... even in the case I've no knowledge about the server ReportingServices is running.)
I am trying to query a list in sharepoint using its lists.asmx webservice and in turn its GetListItems call. I currently have the call working using the following code in the Querystring for the report
<Query>
<Method Namespace="http://schemas.microsoft.com/sharepoint/soap/" Name="GetListItems"/>
<SoapAction>http://schemas.microsoft.com/sharepoint/soap/GetListItems</SoapAction>
</Query>
This seems to work fine except that the list has some empty fields in the first record and for some unbelivable reason they (the empty fields) do not get returned as part of the dataset unless i put a value into them. I then came across a parameter for GetListItems called viewFields which is supposed to . Tehn sample Soap request is shown as follows
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlnsoap="http://schemas.xmlsoap.org/soap/envelope/">

As i have a parameter for viewfields setup.... What value do i pass to it ??? My XML is in its infancy but i though something along the lines of the following would do as an input.
<FieldRef Name='Title'/><FieldRef Name='Address1'/>
Also, maybe i am going the wrong way about this.Is there an easier way of defining the Parameters as part of the Querystring or do Parameters always have to be setup in the parameters tab (My Parameter values are static and will never change).
I I work for a small business who has a somewhat successful ecommerce site. Our website is based on some VERY large DB's with 10's of millions of records, and 40+GB of images, so we choose to self host so we could easily manage the data. As things have grown and we've cobbled a fair amount of integration between the website databases and our internal systems. Fast forward 4-5 years, the website has grown to the point that self hosting is costing us a fortune in bandwidth costs, so I'm thinking of moving to a co-location facility. If I do that, I need to send the website tables along with it. Is there a replication stradagy that would allow us to have two independant DB's, both able to take updates that would sync with one another? My other thought is to spit the tables on two different DB's and let some of the data live in the co-location facility.. but I am worried about the performance impact for local users.

I have a SQL Server 2005 HTTP endpoint. I create a transaction scope in a client application and call two methods on that endpoint. Will the operations performed in the two methods, really, be in a transaction?
In other words, will SQL Server enlist in the ambient transaction even when I am accessing it through a HTTP endpoint?
