Output Parameters Versus Recordsets In Stored Procedures

Jul 20, 2005

I've read that stored procedures should use output parameters instead of
recordsets where possible for best efficiency. Unfortunately I need to
quantify this with some hard data and I'm not sure which counters to
use. Should I be looking at the SQL Server memory counters or something
else.

Some Problems With Output Parameters In Stored Procedures

Jul 6, 2004

I have written a simple C# console application that create my own Stored Procedures
the code is here
----------------------------------------------------------------------------

static void Main(string[] args)
{
SqlConnection cn;
string strSql;
string strConnection;
SqlCommand cmd;
strConnection="server=(local);database=Northwind;integrated security=true;";
strSql="CREATE PROCEDURE spmahdi @CustomerID nchar(5) @counter int OUTPUT AS SELECT OrderID, OrderDate,RequiredDate,ShippedDate FROM Orders WHERE CustomerID = @CustomerID ORDER BY OrderID SET @counter=@@rowcount";
cn=new SqlConnection(strConnection);
cn.Open();
cmd=new SqlCommand(strSql,cn);
cmd.ExecuteNonQuery();
cn.Close();
Console.WriteLine("Procedure Created!");
}

------------------------------------------------------------------------------------
but it has some errors becuase of my strSql
strSql="CREATE PROCEDURE spmahdi @CustomerID nchar(5) @counter int OUTPUT AS SELECT OrderID, OrderDate,RequiredDate,ShippedDate FROM Orders WHERE CustomerID = @CustomerID ORDER BY OrderID SET @counter=@@rowcount";
I mean in creating the stored procedure
if i delete the Output parameter from my stored procedure
and my strSql would be somethimg like this
strSql="CREATE PROCEDURE spmahdi @CustomerID nchar(5) AS SELECT OrderID, OrderDate,RequiredDate,ShippedDate FROM Orders WHERE CustomerID = @CustomerID ORDER BY OrderID ";
There will be no errors
I use Visual Studio.NET 2003(full versoin)and MSDE(not Sql Server)
Could someone help me solve this problem?
Thanks and Regards.

////////////////////////////////////////////////////////////////////////////////////////////
I try to do an ADO.NET 2.0-VB 2005 programming in my VB 2005 Express to get @percentage printed out in the VB Form1. I read some articles in the websites and MSDN about this task and I am very confused about "How to Work with Output Parameters & Report their Values in VB Forms": (1) Do I need the Form.vb [Design] and specify its properties of the object and classes I want to printout? (2) After the SqlConnectionString and the connection.Open(), how can I bring the value of @percentage to the Form.vb? (3) The following is my imcomplete, crude draft code:

Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.SqlTypes

Public Class Form1

Dim connectionString As String = "Data Source=.SQLEXPRESS;Initial Catalog=pubs;Integrated Security=SSPI;"

Dim connection As SqlConnection = New

Try

connection.Open()

Dim command As SqlCommand = New SqlCommand("byroyalty", connection)

command.CommandType = CommandType.StoredProcedure
...................................................................
..................................................................
etc.
////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
From the above-mentioned (1), (2) and (3), you can see how much I am lost/confused in attempting to do this task. Please help and give me some guidances and good key instructions for getting the output parameter printed out in the FORM.vb in my VB 2005 Express project.

Closed Recordsets From Stored Procedures

Jun 18, 2001

Hello all,

I'm writing some stored procedures that first do an Insert or an Update, and then also do a Select to return a Recordset back to an ADO client. However an Insert or Update causes a closed recordset to be produced in ADO. I can skip over the closed recordset with the NextRecordset method.

So the question is, is there any way of stopping the closed recordset being returned? I don't want to have to call the NextRecordset method from ADO as this would mean that the client would need to know about the implementation of the stored procedure.

Has anyone got any ideas on how to get round this?

Thanks
Dave Sykes

Application/Security Design: Stored Procedures Versus SQL Queries

Mar 7, 2007

Hello everyone,

I don't know what category would be appropriate for this question but security seems to be close enough.

I have this case scenario: I am running an automated application that extracts data from a web site and stores the data into a table on SQL server 2005. This information is not confidential in the extreme of social insurance #'s, bank account #s, but should not be seen by a typical employee (it has no use for them). After the data has been stored, it retrieves the data from the same table, processes it, and updates the same table. This application runs every hour infinitely.

Should all the insert, update, and select queries be stored under a stored procedure? I am not concern with performance. My concern would fall under design and security.

Is it worth to hide the details of inserting/updating/selecting behind a stored procedure? Or should I just allow the program to send select/update/insert SQL queries?

No employee (other then the developer and the DB admin) or customer ever access this table (They do not have permission from SQL). The username and passwords were created with security in mind.



Any thoughts or ideas?

Thanks for your time, Adrian

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 RetValue As SqlParameter = testCMD.Parameters.Add("RetValue", SqlDbType.Int)

RetValue.Direction = ParameterDirection.ReturnValue

Do While myReader.Read

Console.WriteLine("{0}", myReader.GetString(2))

myReader.Close()

Console.WriteLine("Return Value: " & (RetValue.Value))

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.

How To Output Multiple Recordsets On One Row Using SQL?

Nov 8, 2001

Hello Folks,

Using just SQL (within SQL Server 2000), I'm looking to output 2 (or more) recordsets from a one-to-many join between table all on one row. Help! Can someone please show me how to do this if it can be done.

Below is an example of the situation.

Thanks a lot folks, - Jerry


************* Tables *******************

** ITEMS **
ItemID
=======
10
11
12

** ITEMSTOPARTS **
ItemID ---- PartID ---- Funktion
=================================
10 -------- 100 ------- headlight
10 -------- 120 ------- taillight

** PARTS **
PARTID ---- Manf ---- ProductName
=================================
100 ------- M1 ------ Halogens
120 ------- M2 ------ Red Lights


************* Queries *******************

-- QUERY 1 --
==============
(dashes preserve indentation)

SELECT
- i.itemID AS ItemID,
- p1.partID AS HLPartID,
- p1.manf AS HLManf,
- p1.name AS HLName,
- p2.partID AS TLPartID,
- p2.manf AS TLManf,
- p2.name AS TLName


FROM - ZItems i
- - - - INNER JOIN ZItemsToParts ip
- - - - - - ON i.itemID = ip.itemID AND
- - - - - - (ip.funktion = 'headlight' OR
- - - - - - ip.funktion = 'taillight') AND
- - - - - - i.itemID = 10
- - - - LEFT OUTER JOIN ZParts p1
- - - - - - ON ip.partID = p1.partID AND
- - - - - - ip.funktion = 'headlight'
- - - - LEFT OUTER JOIN ZParts p2
- - - - - - ON ip.partID = p2.partID AND
- - - - - - ip.funktion = 'taillight'


************* Output *******************

Using "Query 1" I get this:
(Note: HL = Headlight; TL = Taillight)

ItemID - HLPartID - HLManf - HLName --- TLPartID - TL Manf - TL Name
================================================== ==============
10 ----- 100 ------ M1 ----- Halogens - NULL ----- NULL ---- NULL
10 ----- NULL ----- NULL --- NULL ----- 120 ------ M2 ------ Red Lights


I wish to output the proceeding two record set in one row
Any ideas how this can be done with SQL Server 2000
(with JOINS in the FROM clause)?
- DESIRED OUTPUT:

ItemID - HLPartID - HLManf - HLName --- TLPartID - TL Manf - TL Name
================================================== =============
10 ----- 100 ------ M1 ----- Halogens - 120 ------ M2 ------ Red Lights

Stored Procedure Output Parameters

Aug 3, 2004

Hi

I've an existing SQL 2000 Stored Procedure that return data in many (~20) output parameters.

I'm starting to use it in a .Net c# application and it seems to insist that I setup all the output parameters:
SqlParameter param = cmd.Parameters.Add("@BackgroundColour",SqlDbType.TinyInt);
param.Direction=ParameterDirection.Output;
even if I only need the value of a single one.
Is this right? Is there a way to avoid coding every one every time?

Stored Procedure And Output Parameters

Mar 23, 2007

Hi,

I hope someone can help.

I've written a stored procedure that returns a value via an output parameter.

I'm calling the stored procedure in an sql session is a loop, and it passes the value back correctly the first time, but all subsequent calls the output parameter appears to have the same value. I believe that I'm making some very basic mistake, but I can't work it out.

Here's how I'm calling the stored procedure several times
begin
declare @instrumentid int
exec GetInstrumentId 'OFX,AUDCHF,p,1,2007-03-20 16:54:21.843,2007-06-20,100.1', @instrumentid output;
select @instrumentid
exec GetInstrumentId 'OFX,AUDUSD,c,2,2007-03-20 16:54:21.843,2007-06-20,100.2', @instrumentid output;
select @instrumentid
exec GetInstrumentId 'OFX,AUDCHF,p,3,2007-03-20 16:54:21.843,2007-06-20,100.3', @instrumentid output;
select @instrumentid
end

And this is the start of the stored procedure

Create PROCEDURE [dbo].[GetInstrumentId]
(@Ticket varchar(250), @InstrumentId int output)
AS


If I call the stored procedure once it gives the corect output, if I call it several times the output parameter (@instrumentid ) never changes.

OUT And OUTPUT - Stored Procedure Parameters.

Nov 19, 2006

Hi All,

The following is a code snippit. My main interests are the OUT and OUTPUT parameter keywords. One returns a single value, and the other seemingly a resultset. OUTPUT returns a single value, however OUT seems to return a list of values. Could I please get this confirmed?

Also, I cannot see how the value being returned by OUT is being iterated...

Any help on the obove two matters is appreciated.

Thank You

Chris

Using Stored Procedures With Parameters

Jun 18, 2004

Hi all,

Just a quick question regarding the use of stored procedures with parameters.

How do I call a stored procedure with a different number of parameters?

For example if:

new SqlParameter("@SectionID", "3"),
new SqlParameter("@Sessionid", Session["ID"])

SqlHelper.ExecuteNonQuery(conn, CommandType.StoredProcedure, spName, sqlParams);

were to change to the following on a different page:

new SqlParameter("@SectionID", "3"),
new SqlParameter("@Sessionid", Session["ID"]),
new SqlParameter("@ExtraVariable", ExtraVariable)

SqlHelper.ExecuteNonQuery(conn, CommandType.StoredProcedure, spName, sqlParams);


How would I handle the different number of parameters in the Stored Procedure?

cheers,

Pete

Stored Procedures And Parameters

Jun 23, 1998

I want to create a stored procedure with SQL Server 6.5 that CAN take 3 parameters, all of which are optional. The declaration for the stored procedure is :
CREATE PROCEDURE BackOrdersII @CustCode varchar(10), @FromDate datetime, @ToDate datetime AS
SELECT * FROM ISO_Details
WHERE DATEDIFF(dd, fldEst_Del_Date, getdate()) > 0 AND CONVERT(char(12),fldActual_Del_Date,3)=`01/01/00` AND CONVERT(char(12),fldEst_Del_Date,3)<>`01/01/00` AND fldDeleted<>1
ORDER BY DATEDIFF(dd, fldEst_Del_Date, getdate()) DESC

How do I formulate the procedure to allow me to select from the table, keeping the current WHERE clause but adding extra items to allow the results to be further filtered depending upon which of the parameters are given to the procedure. Any one, two, or all three parameters could be given.

Sorry if this seems like a simple question but I am only just getting into using stored procedures.

Thanks Rupert

Stored Procedures And Parameters

Aug 24, 2004

Have looked everywhere and cannot find the answer! So perhaps someone here can answer.

I have an Access 2000 front-end to a SQL Server 2000 database.

I know how to create Stored Procedures that receive parameters; and also how to open a Stored Procedure in the query results window using the DoCmd object. For example,

Application.DoCmd.OpenStoredProcedure "MyProc", acViewNormal, acReadOnly

Does anyone know of a way to pass parameters to Stored Procedures & open the result using the DoCmd object? Without getting a parm input dialog?

Alternatively, does anyone know of a way to open a Stored Procedure in the query results view without using the DoCmd object?

Will appreciate any guidance you can provide! Thanks!

Which Is A Better Stored Procedures Verse Parameters

Mar 28, 2007

 
 
My colleague and I (both are newbie’s to .NET) are divided on whether to use stored procedures or parameters.
 
His viewpoint is, using stored procedures you are spreading the load i.e. SQL server and web server etc. This is not a good solution because it is not a portable when it has to be relocated.
 
Is he right?
 
I thought to avoid SQL injection it is best to use stored procedures but I do see his reasoning as well.
 
Yazzy is Very confused!!

Passing Parameters To Stored Procedures

Feb 17, 2005

Hello,

I seached around for an answer to this question but didn't have much luck. Hopefully someone can help.

I am passing two parameters from a web page to a stored procedure. The first paramater @Field is the name of the field in the database I want to search, the second @Value is the value to seach for. The @Value works fine but the SP does not seem to recongnize the field parameter. I'm not sure if what I am attemping is not supported or wheather I just need to format the @Field in a different manner. The code and stored procedure is below.

Thanks for your help, Gary

Here is the web code:


Dim conMSS As New SqlConnection(ConfigurationSettings.AppSettings("dsnMSS"))
Dim cmdItems As New SqlCommand("DS-SPRS.dbo.s_ItemLookUp", conMSS)

cmdItems.CommandType = CommandType.StoredProcedure
cmdItems.Parameters.Add(New SqlParameter("@Field", SqlDbType.VarChar, 50))
cmdItems.Parameters.Add(New SqlParameter("@Value", SqlDbType.VarChar, 50))

cmdItems.Parameters("@Value").Value = txtValue.Text & "%"
cmdItems.Parameters("@Field").Value = lstField.SelectedValue

conMSS.Open()
dgdItems.DataSource = cmdItems.ExecuteReader
dgdItems.DataBind()
conMSS.Close()


Here is the stored procedure:



CREATE PROCEDURE s_ItemLookUp

@Field AS VARCHAR(50),
@Value AS VARCHAR(50)

AS


SELECT DIV_NO, DIV_NM, LN_NO, LN_DS, ITM_NO, PRD_DS, ITM_MFG_NO, VND_HFC_NM

I need to create a SP that will accept a varying number of input parameters. A form that the user completes has a several controls that serve to narrow the number of records returned. The more parameters given, the fewer rows returned. In the past I have accomplished this by dynamically building an SQL statement. I dosen't appear possible to pass an SQL statement in a variable to a SP. Any help or pointers would be appreciated.

Identifying Specified Parameters In Stored Procedures

Jul 20, 2005

I am using SQL Server 2000. I have a table with, say, 20 columns. Ihave one procedure which updates all 20 columns at once, accepting aparameter for each column. However, I want to be able to pass anycombination of parameters and only update those columns if passed. SoI created the sp as something likecreate update_t1(@col1 int = null,@col2 int = null,@col3 int = null,....@col20 int = null)asupdate t1set col1 = @col1,col2 = @col2,col3 = @col3,.....col20 = @col20This way I can explicitly specify columns or not as I choose. Forexample I could call "exec update_t1 @col1 = 23, @col4 = 49" to updateonly the first and fourth column. Of course this will obviouslyupdate the remaining columns to null. Is there any way to identifywithin the procedure which parameters were actually specified? Ican't simply do a null check because the user could be updating thevalue to be null. Is there any way for the procedure to know theexact command that invoked it?For example, if I called "exec update_t1 @col1 = 23, @col4 = 49" Iwould want to know only col1 and col4 were specified. If I called"exec update_t1 @col1 = 23, @col4 = 49, @col17 = null" I would want toknow that col1, col4 and col17 were specified, even though col17 wasset to the default of null.

Issue With NULLs And Output Parameters In A Stored Procedure.

Jun 12, 2008

I am trying to set up a stored procedure to return details about an item in my database. Say I use the following declarations for a stored procedure:
 
@Parameter1 int output,
@Parameter2 varchar(200) output,
@Parameter3 int output
 
and then I used a query like:
 
select @Parameter1 = table.field1, @Parameter2 = table.field2, @Parameter3 = table.field3 from table where itemID = 7
 
to populate the output parameters the problem I am running into is that if @Parameter1 is null, then @Parameter2 and @Parameter3 also return as null.  But, If i rewrite the declarations to:
 
@Parameter3 int output,
@Parameter2 varchar(200) output,
@Parameter1 int output
 
then, with the same query, @Parameter3 and @Parameter2 get the values they should, even if @Parameter1 is null
 
does anyone have any ideas?
 
I guess another question is, I am right now in the code itself (not the demonstration here) returning 6 values, since this procedure will only ever return one record, I decided to implement it as output variables, rather than returning a 1 record result set to the application.  Am I better off just returning the 1 record result set then parsing it out into variables in the application?
 
Thanks in advance
