Managed Stored Procedures (GetClusterDiscrimination) Crash - Any Suggestions?

Dec 21, 2006

I profiled the following on my Analysis server:



CALL System.Microsoft.AnalysisServices.System.DataMining.Clustering.GetClusterDiscrimination('Page Aggregate By Month2','001','010',0.0005,true)



Internal error: An unexpected exception occured. Execution of the managed stored procedure GetClusterDiscrimination failed with the following error: Exception has been thrown by the target of an invocation.Object reference not set to an instance of an object..



Any ideas ?

Sp_sproc_columns Does Not Seem To Work On Managed Stored Procedures

Jul 10, 2007

Hi,



I have written a stored procedure using C#.NET. I deployed it to SQL Server, and everything works fine.



However, an Third-Party app needs to see what parameters it can use for this SP by executing sp_sproc_columns <SP name>



sp_sproc_columns

Seems to work on normal SP's written in T-SQL, but not on Managed SP's. On my SP, sp_sproc_columns does not seem to work. It does not return the parameters. On normal SP's, it does.



Anyone have an idea why this is?

Error Deploying Managed Stored Proc

Jul 24, 2006

When I try to deploy this managed stored proc assembly on SQL Server 2005 I get this error:
Failed to initialize the Common Language Runtime (CLR) v2.0.50727 with HRESULT 0x8007000e. You may fix the problem and try again later
I looked on the net but found no documentation about it.  I know the CLR v2.0 is working as I have some ASP.NET apps running from this server that use it.  Any ideas?

Add User Assembly In Managed Stored Procedure

May 4, 2006

I am developing a managed stored procedure in VS.NET 2005 and I am trying to add a reference to an user developed assembly (not a system one) but adding a reference to it is not possible as it doesnt let me import assemblies but rather reference the few limited ones in a list. Why is this??

Managed Code In SQL Server 2005 And Stored Procedure Name Qualification

Mar 11, 2008

All --
Please help.
I am using managed code in SQL Server 2005 and have a question about stored procedure name qualification.
With a VS.NET 2005 Pro Database project, when I use >Build, >DeploySolution, it works great but my stored procedures are named with qualification using my domainusername.ProcName convention, something like this...
XYZ_TECHKamoskiM.GetData
 ...when I want them to be named with the dbo.ProcName convention, something like this...
dbo.GetData
...and I cannot see where this can be changed.
Do you happen to know?
Please advise.
(BTW, I have tried going to this setting >Project, >Properties, >Database, >AssemblyOwner, and putting in the value "dbo" but that does not do what I want.)
(BTW, as a workaround, I have simply scripted the procedures, so that I can drop them and then add them back with the right names-- but, that is a bit tedious and wasted effort, IMHO.)
Thank you.

Stored Procedures 2005 Vs Stored Procedures 2000

Sep 30, 2006

Hi,



This Might be a really simple thing, however we have just installed SQL server 2005 on a new server, and are having difficulties with the set up of the Store Procedures. Every time we try to modify an existing stored procedure it attempts to save it as an SQL file, unlike in 2000 where it saved it as part of the database itself.



Thank you in advance for any help on this matter

All My Stored Procedures Are Getting Created As System Procedures!

Nov 6, 2007



Using SQL 2005, SP2. All of a sudden, whenever I create any stored procedures in the master database, they get created as system stored procedures. Doesn't matter what I name them, and what they do.

For example, even this simple little guy:

CREATE PROCEDURE BOB

AS

PRINT 'BOB'

GO

Gets created as a system stored procedure.

Any ideas what would cause that and/or how to fix it?

Thanks,
Jason

Using A Stored Procedure To Query Other Stored Procedures And Then Return The Results

Jun 13, 2007

Seems like I'm stealing all the threads here, : But I need to learn :) I have a StoredProcedure that needs to return values that other StoredProcedures return.Rather than have my DataAccess layer access the DB multiple times, I would like to call One stored Procedure, and have that stored procedure call the others to get the information I need. I think this way would be more efficient than accessing the DB  multiple times. One of my SP is:SELECT I.ItemDetailID, I.ItemDetailStatusID, I.ItemDetailTypeID, I.Archived,     I.Expired, I.ExpireDate, I.Deleted, S.Name AS 'StatusName', S.ItemDetailStatusID,    S.InProgress as 'StatusInProgress', S.Color AS 'StatusColor',T.[Name] AS 'TypeName',    T.Prefix, T.Name AS 'ItemDetailTypeName', T.ItemDetailTypeID    FROM [Item].ItemDetails I    INNER JOIN Item.ItemDetailStatus S ON I.ItemDetailStatusID = S.ItemDetailStatusID    INNER JOIN [Item].ItemDetailTypes T ON I.ItemDetailTypeID = T.ItemDetailTypeID However, I already have StoredProcedures that return the exact same data from the ItemDetailStatus table and ItemDetailTypes table.Would it be better to do it above, and have more code to change when a new column/field is added, or more checks, or do something like:(This is not propper SQL) SELECT I.ItemDetailID, I.ItemDetailStatusID, I.ItemDetailTypeID, I.Archived,     I.Expired, I.ExpireDate, I.Deleted, EXEC [Item].ItemDetailStatusInfo I.ItemDetailStatusID, EXEC [Item].ItemDetailTypeInfo I.ItemDetailTypeID    FROM [Item].ItemDetails IOr something like that... Any thoughts?

How To Save Stored Procedure To NON System Stored Procedures - Or My Database

May 13, 2008

Greetings:

I have MSSQL 2005. On earlier versions of MSSQL saving a stored procedure wasn't a confusing action. However, every time I try to save my completed stored procedure (parsed successfully ) I'm prompted to save it as a query on the hard drive.

How do I cause the 'Save' action to add the new stored procedure to my database's list of stored procedures?

Thanks!

Stored Procedure Being Saved In System Stored Procedures

Apr 7, 2006

We recently upgraded to SQL Server 2005. We had several stored procedures in the master database and, rather than completely rewriting a lot of code, we just recreated these stored procedures in the new master database.

For some reason, some of these stored procedures are getting stored as "System Stored Procedures" rather than just as "Stored Procedures". Queries to sys.Objects and sys.Procedures shows that these procs are being saved with the is_ms_shipped field set to 1, even though they obviously were not shipped with the product.

I can't update the sys.Objects or sys.Procedures views in 2005.

What effect will this flag (is_ms_shipped = 1) have on my stored procedures?

Can I move these out of "System Stored Procedures" and into "Stored Procedures"?

Thanks!

SSIS And Stored Procedures Results Stored In #Tables

Mar 26, 2008

Hello
I'm start to work with SSIS.

We have a lot (many hundreds) of old (SQL Server2000) procedures on SQL 2005.
Most of the Stored Procedures ends with the following commands:


SET @SQLSTRING = 'SELECT * INTO ' + @OutputTableName + ' FROM #RESULTTABLE'

EXEC @RETVAL = sp_executeSQL @SQLSTRING


How can I use SSIS to move the complete #RESULTTABLE to Excel or to a Flat File? (e.g. as a *.csv -File)

I found a way but I think i'ts only a workaround:

1. Write the #Resulttable to DB (changed Prozedure)
2. create data flow task (ole DB Source - Data Conversion - Excel Destination)

Does anyone know a better way to transfer the #RESULTTABLE to Excel or Flat file?

Thanks for an early Answer

Calling Stored Procedures From Another Stored Procedure

May 8, 2008

I am writing a set of store procedures (around 30), most of them require the same basic logic to get an ID, I was thinking to add this logic into an stored procedure.

The question is: Would calling an stored procedure from within an stored procedure affect performance? I mean, would it need to create a separate db connection? am I better off copying and pasting the logic into all the store procedures (in terms of performance)?

Thanks in advance

John

Calling A Stored Procedure Inside Another Stored Procedure (or Nested Stored Procedures)

Nov 1, 2007

Hi all - I'm trying to optimized my stored procedures to be a bit easier to maintain, and am sure this is possible, not am very unclear on the syntax to doing this correctly.  For example, I have a simple stored procedure that takes a string as a parameter, and returns its resolved index that corresponds to a record in my database. ie
exec dbo.DeriveStatusID 'Created'
returns an int value as 1
(performed by "SELECT statusID FROM statusList WHERE statusName= 'Created') 
but I also have a second stored procedure that needs to make reference to this procedure first, in order to resolve an id - ie:
exec dbo.AddProduct_Insert 'widget1'
which currently performs:SET @statusID = (SELECT statusID FROM statusList WHERE statusName='Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
I want to simply the insert to perform (in one sproc):
SET @statusID = EXEC deriveStatusID ('Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
This works fine if I call this stored procedure in code first, then pass it to the second stored procedure, but NOT if it is reference in the second stored procedure directly (I end up with an empty value for @statusID in this example).
My actual "Insert" stored procedures are far more complicated, but I am working towards lightening the business logic in my application ( it shouldn't have to pre-vet the data prior to executing a valid insert). 
Hopefully this makes some sense - it doesn't seem right to me that this is impossible, and am fairly sure I'm just missing some simple syntax - can anyone assist?

Help With Stored Procedures

Hello I have two stored procedures
@ID INT
AS
SELECT (CASE WHEN NUM >= 10 THEN CAST(PAID AS FLOAT) / CAST(NUM AS FLOAT) * 100 WHEN NUM < 10 THEN 0 END) AS PER
FROM (SELECT (SELECT COUNT(*) AS Expr1

Events AS E ON E.id = D.Event_id
WHERE (D.Transaction_type = 1) AND (D.Player_id = @ID)) AS NUM,
(SELECT COUNT(*) AS Expr1
FROM Event_data AS D LEFT OUTER JOIN
Events AS E ON E.id = D.Event_id
WHERE (D.Transaction_type = 1) AND (D.Transaction_value > 0) AND (D.Player_id = @ID)) AS PAID) AS X

(SELECT SUM(TRANSACTION_VALUE)
FROM EVENT_DATA WHERE PLAYER_ID=@ID AND TRANSACTION_TYPE=1
GROUP BY PLAYER_ID),0) AS WINNINGS FROM PLAYERS P
undefined P
 
The first returns a percentage for player wins, the second gives me a photo and sums the player winnings
 I would like to combine the results so I can get the percentage and wininngs in one query,  in another matter all together I would like create a procedure like the first but instead of returning only one player, I would like to return the percentage for each player
Thanks in advance for any light you can shine on this.
