Calling Stored Procedures On Different Servers
Oct 4, 2004
I'm using reporting services to build a report and I plan on using a stored procedure to gather my data for the report. My question is:
I know it's possible to call a stored procedure from a stored procedure, both within the same dB and in different dB's, but is it possible to call a SP that's on a different server? My gut says "definitely not. at least not easily." But I wanted to see if anyone had any thoughts on this before I pursue a different course of action.

Hi All... I'm calling a stored procedure from C#. I'm sending it input parameters as follows:SqlCommand c = new SqlCommand("AddAuthor", myConnection);c.CommandType = CommandType.StoredProcedure;
c.Parameters.Add(new SqlParameter("@LastName", SqlDbType.VarChar, 100));c.Parameters["@LastName"].Value = "Last";
c.Parameters.Add(new SqlParameter("@FirstName", SqlDbType.VarChar, 100));c.Parameters["@FirstName"].Value = "First";
In my opinion, that works nice - and it's easy. The reference I'm using says I can also specify "output" parameters - instead of supplying a value, one needs to change a property called direction.
But my stored procedure doesnt return any output parameters per se, but it does return a value. That is the last statement in the stored procedure is "RETURN @@IDENTITY" - it returns the identity field after an INSERT... So how do I get that value back in my C# code?
Thanks for the help in advance. Happy 4th to all! : ) -- Curt

Hi,
I was wondering if someone can tell me why my sub for calling stored procedures doesn't work.The string strFinFileId is not null.
I keep getting the following error System.IndexOutOfRangeException: Total
Here's my sub.
'//get GrandTotal Protected Sub GetGrandTotal(ByVal finfileid As String) Dim myConnection As SqlConnection Dim connString As String Dim strFinFileId As String Dim strGrandTotal As Decimal
strFinFileId = finfileid connString = ConfigurationManager.ConnectionStrings("PMOConnectionString1").ConnectionString
myConnection = New SqlConnection(connString) 'you need to provide password for sql server myConnection.Open()
Dim sql1 As String
sql1 = "GetGrandTotal " & Convert.ToInt32(strFinFileId)
Dim myCommand As SqlCommand
'Response.Write(sql1) 'Response.End()
myCommand = New SqlCommand(sql1, myConnection)
Dim reader As SqlDataReader = myCommand.ExecuteReader() While reader.Read() strGrandTotal = reader.Item("Total") LabelGrandTotal.Text = strGrandTotal 'Response.Write(strFinFileId) 'Response.End()
End While reader.Close() myConnection.Close() End Sub
Cheers
Mark :)

I have a stored procedure written to update a table:
The stored procedure has the following parameters:
@Original_TypeID int,
@Type_Desc varchar(35),
@Contact_Name varchar(20),
@Contact_Ad1 varchar(25),
@Contact_Ad2 varchar(25),
@Contact_City varchar(10),
@Contact_Phone varchar(12),
@Contact_Fax varchar(12),
@Contact_Email varchar(35)
And I want to call this procedure when the "update" button is clicked, my code is:Protected Sub UpdateButton_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim myConnection As New SqlConnection(ConfigurationManager.ConnectionStrings("myConnectionString").ConnectionString)Dim myCommand As SqlCommandDim UpdteParam As New SqlParameter()
myConnection.Open()myCommand = New SqlCommand("[dbo].[sp_Update_Types]", myConnection)
myCommand.CommandType = CommandType.StoredProcedure
????????????????????????myCommand.Parameters.Add(UpdateParam)
???????????myCommand.ExecuteNonQuery()
myConnection.Close()
End Sub
Can you please help me with the ????? areas? I don't know how to pass the parameters into the procedure, and also the second set of ??? s, I'm not sure if I am executing the command correctly.
Thank you.

I'm relatively new to SQL Server and I was wondering if there is any way to call a DLL from a regular stored procedure? I believe I've read that the extended stored procedure is a DLL and therefore should be able to call another DLL. Can this also be verified? We're looking to speed up some sections of Visual Basic code which does some heavy I/O work. I've also asked this once before but didn't get an absolute answer - can you write the extended stored procedures in Visual Basic or is C/C++ the only language supported right now?
Thanks.

Is it possible to have a stored procedure in database A while callingit from database B and have it manipulate the tables in database B(whatever the calling database happens to be)?We have a large-scale app that uses many complex stored procedures,and as of now, we're copying the SPs to every new database that iscreated, and it will soon become a nightmare for propagating updatesand fixes. We'd like to keep a master set of the SPs in one DB and"use" them from other DBs so that they only query data and manipulatetables in the calling DB. I hope someone has some suggestions. Thanks.

I have a simple stored procedure:
create procedure sp_testres
@mult1 int,
@mult2 int,
@result int output
as
select @result = (10*@mult1) + @mult2
go
When I call it
declare @result int
exec sp_testres 5, 6, @result output
print @result
(Result is correctly shown as 56).
I then in C# wrote the following:
m_cmd.CommandText = "sp_testres";
SqlParameter param2 = new SqlParameter("@mult2", SqlDbType.Int);
param2.Value = 6;
SqlParameter param1 = new SqlParameter("@mult1", SqlDbType.Int);
param1.Value = 5;
SqlParameter param3 = new SqlParameter("@result", SqlDbType.Int);
param3.Direction = ParameterDirection.Output;
m_cmd.CommandType = CommandType.StoredProcedure;
m_cmd.Parameters.Add(param1);
m_cmd.Parameters.Add(param2);
m_cmd.Parameters.Add(param3);
m_cmd.ExecuteNonQuery();
This works and param3.Value holds the result value.
I also notice that I can supply the parameters in any order, and things work fine.
What I want to know is: can I call the stored procedure with parameters, where I haven't supplied the parameter name, and just rely on the parameter order matching instead?

Hello All,
We are trying to figure out how to make a stored procedure call and pass some inputs using C# and plain ADO. We are able to call an empty stored procedure but cannot pass parameters into a stored procedure.
Does anyone have sample code in C# whereby we can open a connection and pass inputs into a stored procedure? The following is a sample code we are using:
ADODB.Parameter param = new ADODB.Parameter();
param=cmd.CreateParameter("@StoreID", ADODB.DataTypeEnum.adInteger, ADODB.ParameterDirectionEnum.adParamInput,sizeof(int) , 9);
cmd.Parameters.Append(param);
ADODB.Recordset rsInv = cmd.Execute(out objAffected, ref objAffected,-1 );
In the above example, we create a parameter of type integer and try to add it to the ADO Command object. It is supposed to return a recordset. It returns a recordset with record count -1.
Sincerely,
Dwight Kulkarni

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

I have created a cursor using the following type of syntax:
DECLARE MyCursor CURSOR FOR
SELECT ID FROM tblEmployees
OPEN MyCursor
BEGIN
FETCH NEXT FROM MyCursor
END
CLOSE MyCursor
Instead of the SELECT statement (SELECT ID FROM tblEmployees), I actually have a very complex select statement. I have created a stored procedure to handle this select. However, I cannot find a way to call a stored procedure in place of the SELECT statement in the cursor. Is this possible? Thanks.

Hi guys, hoping one of you may be able to help me out. I am using VS 2005, and VB.net for a Windows application.
I have a table in SQL that has a list of Storedprocedures: Sprocs Table: SPID - PK (int), ID (int), NAME (string), TYPE (string)The ID is a Foreign key (corresponding to a Company ID), the name is the stored procedure name, and Type (is the type of SP).
On my application I need to a certain SP depending on the company selected and what page you are on. I have a seperate SP that passes in parameters for both Company, and Type and should output the Name value:
ALTER PROCEDURE [dbo].[S_SPROC] ( @ID int, @TYPE CHAR(10), @NAME CHAR(20) OUTPUT )AS
SELECT @NAME = NAME FROM SPROCSWHERE [ID] = @IDAND [TYPE] = @TYPE
Unfortunately I dont seem to be able to get the output in .Net, or then be able to fill my dataset with the Stored Procedure.Has anyone done something similar before, or could point me in the right direction to solving this problem.
ThanksPhil

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've been trying to copy tables from a linked server to a SQL ServerExpress database. Express seems to have no direct/automatic way to doit, so I've been looking into doing this by hand (i.e., with a T-SQLprocedure).I've discovered some system stored procedures that seem relevant (likesp_tables_ex and sp_columns_ex). But they're procedures, nottable-valued functions, so I'm not sure if I can actually do anythingwith the data they return.If I could get to the data, I thought maybe I could use a cusor and awhile loop to recreate the tables in Express.Is this crazy?Really could use some advice on this.Thanks,-Dan

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?

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

I need a less robust solution that I implement tomorrow that doesn't involve buying third party tools and a more robust long term strategy that could if need make use of third party tools.

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?

Hi Peeps
I have a SP that returns xml
I have writen another stored proc in which I want to do something like this:Select FieldOne, FieldTwo, ( exec sp_that_returns_xml ( @a, @b) ), FieldThree from TableName
But it seems that I cant call the proc from within a select.
I have also tried
declare @v xml
set @v = exec sp_that_returns_xml ( @a, @b)
But this again doesn't work
I have tried changing the statements syntax i.e. brackets and no brackets etc...,
The only way Ive got it to work is to create a temp table, insert the result from the xml proc into it and then set @v as a select from the temp table -
Which to be frank is god awful way to do it.
Any and all help appreciated.

which i've converted to a stored procedure: 1 ALTER PROCEDURE [dbo].[insert_DagVerslagDetail]
2 -- Add the parameters for the stored procedure here
3 @dagverslagdetailID int,
4 @logID int,
5 @categorieID int,
6 @inhoud varchar(100)
7 AS
8 BEGIN
9 -- SET NOCOUNT ON added to prevent extra result sets from
10 -- interfering with SELECT statements.
11 SET NOCOUNT ON;
12 SET @dagverslagdetailID = SCOPE_IDENTITY()
13
14 -- Insert statements for procedure here
15 BEGIN TRANSACTION
16 INSERT LogDetail (LogID, CategorieID, Inhoud)
17 VALUES(@logID, @categorieID, @inhoud)
18 COMMIT TRANSACTION
19 END
Now i would like to call that stored procedure in my previous method, so i've changed it to this:
1 public void AddDagVerslagCategorie(int logID, HistoriekDetail historiekDetail)
2 {
3 SqlConnection oConn = new SqlConnection(_connectionString);
4 string strSql = "insert_DagVerslagDetail";
5 strSql += "values(@logID, @categorieID, @inhoud)";
6 SqlCommand oCmd = new SqlCommand(strSql, oConn);
7 oCmd.CommandType = CommandType.StoredProcedure;
8 oCmd.Parameters.Add(new SqlParameter("@logID", SqlDbType.Int)).Value = logID;
9 oCmd.Parameters.Add(new SqlParameter("@categorieID", SqlDbType.Int)).Value = historiekDetail.CategorieID;
10 oCmd.Parameters.Add(new SqlParameter("@inhoud", SqlDbType.VarChar, 100)).Value = historiekDetail.Inhoud;
11
12 try
13 {
14 oConn.Open();
15 int rowsAffected = oCmd.ExecuteNonQuery();
16 if (rowsAffected == 0) throw new ApplicationException("Fout toevoegen historiek detail");
17 oCmd.CommandText = "select @@IDENTITY";
18 oCmd.Parameters.Clear();
19 historiekDetail.HistoriekDetailID = (int)(decimal)oCmd.ExecuteScalar();
20 }
21 catch (Exception ex)
22 {
23 throw new ApplicationException("Fout toevoegen historiek detail: " + ex.Message);
24 }
25 finally
26 {
27 if (oConn.State == ConnectionState.Open) oConn.Close();
28 }
29 }
Do i still need the lines 17 oCmd.CommandText = "select @@IDENTITY";
19 historiekDetail.HistoriekDetailID = (int)(decimal)oCmd.ExecuteScalar();
Because i've declared the identity in my stored procedure

Hi, I have a stored procedure, and it is expecting an output. If I declared the passing varaible as ref, it compiles fine, but it is not returning any value. If I pass the varaible as out, and add the paramater
MyComm.Parameters.Add(new SqlParameter("@ReturnValue", returnValue)); it gives the following error.
Compiler Error Message: CS0269: Use of unassigned out parameter 'quoteID'.
And if I don't supply the previous statement, the following error occurs.
System.Data.SqlClient.SqlException: Procedure 'CreateData' expects parameter '@ReturnValue', which was not supplied.
How Can I fix this? thanks.
