Stored Procedure && Returned Values

Dec 23, 2007

I have a stored procedure that selects * from my table, and it seems to be working fine:

 USE myDB
GO
IF OBJECT_ID ( 'dbo.GetAll', 'P') IS NOT NULL
DROP PROCEDURE GetAll
GO
CREATE PROCEDURE GetAll
AS
DECLARE ref_cur Cursor
FOR
SELECT * FROM myTable
Open ref_cur
FETCH NEXT FROM ref_cur
DEALLOCATE ref_cur
 

The problem is, I'm trying to create a DB class, and I'm not sure what Parameter settings I'm supposed to use for my returned values.  Can anyone help me finish this?public class dbGet_base
{
public dbGet_base()
{
_requestId = 0;
}

public dbGet_base(Int64 RequestId)
{
this._requestId = RequestId;
getDbValues(RequestId);
}
public void getDbValues(Int64 RequestId)
{
getDbValues(RequestId, "GetAll");
}
public void getDbValues(Int64 RequestId, string SP_Name)
{
using(SqlConnection Conn = new SqlConnection(ConfigurationManager.AppSettings["WSConnection"]))
using (SqlCommand Command = new SqlCommand(SP_Name, Conn))
{
Command.CommandType = CommandType.StoredProcedure;
Command.Parameters.Add("@Request_Id", SqlDbType.Int).Value = RequestId;
Command.Parameters.Add(??

Can The OLE DB Command Transformation Support Multiple Values Returned By A Stored Procedure Or Is The Limit One Value Only?

Apr 10, 2007

I have no problem getting OLE DB Command transformations to support single returns by a procedure.

For example, exec name_of_procedure ?,?,? OUTPUT



However, I have a stored procedure which accepts 1 input and returns 5 outputs. This procedure works fine at the command line but when I try to incorporate it into a OLE DB Command I don't get the multiple values returned. There's no problem at all configuring the transform as it recognizes all input and output parameters. For some reason I just don't get values returned.



thanks

How To Get The Returned Value From A Stored Procedure?

Sep 26, 2007

Hi,
I use a strong-typed DataSet to build the data access tier of my application, and the IDE generates most of code for me. However I can't find a way to get the value returned by a stored procedure(The stored procedure seems like 'RETURN 0').I noticed that a @RETURN_VALUE parameter is added automatically for each query method, but I don't know how to read the value.
Anybody could help me with the problem? Thanks.

Use Resultset Returned From A Stored Procedure In Another Stored Procedure

Nov 15, 2006

I have a store procedure (e.g. sp_FetchOpenItems) in which I would like to call an existing stored procedure (e.g. sp_FetchAnalysts). The stored proc, sp_FetchAnalysts returns a resultset of all analysts in the system.
I would like to call sp_FetchAnalysts from within sp_FetchOpenItems and insert the resultset from sp_FetchAnalysts into a local temporary table. Is this possible?
 Thanks,
Kevin

Incorrect Value Returned From Stored Procedure

Sep 26, 2006

I have an asp.net 1.1 website that uses sql server 2000 and vb.I have a bit of a dilema, when I run a stored procedure in a webpage it returns the wrong value, but if I run itin the query analyzer the correct value is returned. Dim orderHistory As nlb.OrdersDB = New nlb.OrdersDB

' Obtain Order ID from QueryString
Dim OrderID As Integer = CInt(Request.Params("ID"))

' Get the customer ID too
Dim myNewCustomerId As Integer = 0
myNewCustomerId = orderHistory.GetOrderCustomer(OrderID)



Public Function GetOrderCustomer(ByVal orderID As Integer) As Integer

' Create Instance of Connection and Command Object
Dim myConnection As SqlConnection = New SqlConnection(ConfigurationSettings.AppSettings("ConnectionString"))
Dim myCommand As SqlCommand = New SqlCommand("nlbsp_OrdersCustomerID", myConnection)

' Mark the Command as a SPROC
myCommand.CommandType = CommandType.StoredProcedure

' Add Parameters to SPROC
Dim parameterOrderID As New SqlParameter("@order_id", SqlDbType.Int, 4)
parameterOrderID.Value = orderID
myCommand.Parameters.Add(parameterOrderID)

Dim parameterOrderCustID As New SqlParameter("@customer_id", SqlDbType.Int, 4)
parameterOrderCustID.Value = ParameterDirection.Output
myCommand.Parameters.Add(parameterOrderCustID)

'Open the connection and execute the Command
myConnection.Open()
myCommand.ExecuteNonQuery()
myConnection.Close()

' Return the customer_id (obtained as out paramter of SPROC)

If parameterOrderCustID.Value <> 0 Then
Return CInt(parameterOrderCustID.Value)
Else
Return 0
End If

End Function


the stored procdure is
CREATE PROCEDURE [dbo].[nlbsp_OrdersCustomerID]
(
@order_id int,
@customer_id int OUTPUT
)
AS

/* Return the customer_id from the Orders. */
SELECT
@customer_id = customer_id

FROM
nlb_Orders

WHERE
order_id = @order_id
GO

 I know a particular order_id returns a value of 1. But when I run it in the webpage it always comes back as 2. Any ideas would be appreciated ThanksPete

Stored Procedure - Too Many Rows Returned

Jan 12, 2007

The following query only brings back too much data in the table - there are duplicates and the lab it shows is wrong.
The problem is:  
AND a.calLab = f.ID
in the Where statement.
Some equipment does not need calibration, so, a.calDueDate = 0 AND a.calLab would be NULL or 0.
tblLabs ID field has 1 - 18 (Labs) - no 0 and of course no null
I need to get the rest of the data.
Any suggestions?
Thanks.....

SELECT a.assignedID,
b.Manufacturer,

Stored Procedure Works But Nothing Returned?

Mar 4, 2004

Hello,

I have the following stored prod in SQL server:

CREATE PROC spValidateUserIdAndPassword

@UserIdvarchar(50),
@Passwordvarchar(50)
AS
SELECT tblAdvertisers.UserID, tblAdvertisers.Password
FROM tblAdvertisers
WHERE ((tblAdvertisers.UserID = @UserId) AND (tblAdvertisers.Password = @Password))


I can run it in Query Analyzer and it returns one record as it should. I want it in ASP.NET to return the amount of rows that are effected, e.g that the login is correct.

The code I have is:


public bool ValidateUserIdAndPassword(string userId, string password)
{
sqlCommand.CommandType = CommandType.StoredProcedure;
//the name of the stored procedure
sqlCommand.CommandText = "spValidateUserIdAndPassword";

SqlParameter myParam;

//add the param's to the SP

//userId information for the user
myParam = new SqlParameter("@UserId", SqlDbType.VarChar, 50);
myParam.Value = CStr(userId);
sqlCommand.Parameters.Add(myParam);

//password information for the user
myParam = new SqlParameter("@Password", SqlDbType.VarChar, 50);
myParam.Value = CStr(password);
sqlCommand.Parameters.Add(myParam);

try
{
int rows = sqlCommand.ExecuteNonQuery();

if(rows == 1)
return true;
else
return false;

}
catch(System.Exception er)
{
//for design time error checking
return false;
}



This returns -1...

Please help me

Kind Regards

Stored Procedure Syntax - Value Not Returned

Feb 5, 2004

I have the following stored procedure. The good thing is I finally got the syntax to the point where it doesn't blow up, but I was under the impression the "print" statement would print my result. In this case all I get is the statement ' 1 Row Affected ' which by the way is not the answer I was expecting.

Here's the code:
'
CREATE PROCEDURE createevents
AS

declare @myvariable varchar(700)

declare @myvar varchar(700)

begin
Select @myvariable = d.id
from table1 d, table2 dc where d.class = dc.class

If @myvariable > 0
begin
Select @myvar =dp. class
from table3 dp, table2 dc
where dp.class = dc.class

If @myvariable >= 1
begin
print @myvariable + (',') + @myvar
end
end

else
begin
print @myvariable + ('is empty')
end
end

'
Thanks in advance for any help.

Value That Is Returned If An Insert Is Not Performed From A SQL Stored Procedure.

Sep 14, 2007

I am using the following stored procedure to insert a value into the database. I am new to stored procedures so I need help. Basically this stored procedurewill only insert a value for "CustomerName" if it is not a duplicate value.
So I noticed in My C# when I call this stored procedure, a negative one "-1"is returned if the insert is not performed because of a duplicate value.
Is that correct? Should I be getting back a negative one "-1" ? You seeI thought that a Zero "0" would be returned if the insert was not performed.Not a negative one?
SET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGO
CREATE PROCEDURE [dbo].[CustomerCreate](  @CustomerDescription nvarchar(100),  @CustomerName nvarchar(100),  @LastUpdateDate datetime,  @LastUpdateUser nvarchar(32),  @inserted_record smallint output)
AS
 if exists (select 1 from Customer where CustomerName = @CustomerName) BEGIN
    set @inserted_record = 0
 END    ELSE BEGIN INSERT INTO Customer (  CustomerDescription,  CustomerName,        Active,  LastUpdateDate,  LastUpdateUser ) VALUES (  @CustomerDescription,  @CustomerName,  @LastUpdateDate,  @LastUpdateUser ) END

Limit The Number Of Records Returned In Stored Procedure.

In my ASP page, when I select an option from the drop down list, it has to get the records from the database stored procedure. There are around 60,000 records to be fetched. It throws an exception when I select this option. I think the application times out due to the large number of records. Could some tell me how to limit the number of rows to be returned to avoid this problem. Thanks.

Naming The Result Sets Returned By Stored Procedure

Jul 6, 2004

Greetings

I have a SQL Server stored procedure that performs several queries and therefore returns several "result sets" at any one time.

Wiring it up via ADO.NET I populate a DataSet with a number of items in the Tables collection - which is great - and I can give each item a name for identification purposes once the DataSet is populated.

But I'd like to know if there is some way I can set the names of each result set *within the text of the stored procedure*, i.e. before the DataSet gets populated.

Any help greatly appreciated.

How To Suppress Result Sets Returned From A Stored Procedure?

Aug 28, 2006

I have a novice question. How does one suppress result sets returned from a stored procedure?

I have created a procedure which makes use of multiple stored procedures . The purpose of this procedure (lets call it procA), is to count the rows returned from other procedures. The €œOther€? procedures will return rows having an unknown number of columns. I would like to limit any changes which may be needed to be made to the €œOther€? procs.

Once procA has collected all of the information (@@rowcount) from the inner procedures, then it will return a result set having several columns €“ mainly the subProcedure name and number of rows returned.

The purpose of procA is to query several subsystems and identify which ones need attention.

Cursor While Loop
exec @ProcName @ObjectName,@userID,@syncDate
set @recs = @@rowcount;


My c# program calls the sp as follows:

cmd = DataUtility.GetSQLCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "FetchAdminData";
cmd.Parameters.AddWithValue("@userID", userAlias);
cmd.Parameters.AddWithValue("@adminDate",userDate);
reader = cmd.ExecuteReader();

I do not wish to iterate over each resultSet when I am only interested in the last one. Any suggestions?

SQL 2012 :: SSRS - Force Report To Use Columns Returned From Stored Procedure?

Jul 10, 2015

I have a stored procedure which returns a result set as follows:

(Headers)Total,WV1,WV2,WV3,WV4,WV5.....
(Example data) "Some total name",1,2,3,4,5.....

The WV1, WV2, WV3 column names will be different depending on parameters passed to the stored procedure. In other words, the column names or number of columns aren't fixed (apart from "Total").

What I would like to be able to do is to just force SSRS to use the column headers supplied by the stored procedure as the column names in the report.

NULL Values Returned When Reading Values From A Text File Using Data Reader.

Feb 23, 2007

I have a DTSX package which reads values from a fixed-length text file using a data reader and writes some of the column values from the file to an Oracle table. We have used this DTSX several times without incident but recently the process started inserting NULL values for some of the columns when there was a valid value in the source file. If we extract some of the rows from the source file into a smaller file (i.e 10 rows which incorrectly returned NULLs) and run them through the same package they write the correct values to the table, but running the complete file again results in the NULL values error. As well, if we rerun the same file multiple times the incidence of NULL values varies slightly and does not always seem to impact the same rows. I tried outputting data to a log file to see if I can determine what happens and no error messages are returned but it seems to be the case that the NULL values occur after pulling in the data via a Data Reader. Has anyone seen anything like this before or does anyone have a suggestion on how to try and get some additional debugging information around this error?

How Can I Assign Data Returned From A Stored Procedure Into The Return Table Of A Table Valued Function

Apr 18, 2007

Here is the scenario,
I have 2 stored procedures, SP1 and SP2

SP1 has the following code:

declare @tmp as varchar(300)
set @tmp = 'SELECT * FROM
OPENROWSET ( ''SQLOLEDB'', ''SERVER=.;Trusted_Connection=yes'',
''SET FMTONLY OFF EXEC ' + db_name() + '..StoredProcedure'' )'

EXEC (@tmp)

SP2 has the following code:

SELECT *
FROM SP1 (which won't work because SP1 is a stored procedure. A view, a table valued function, or a temporary table must be used for this)

Views - can't use a view because they don't allow dynamic sql and the db_name() in the OPENROWSET function must be used.
Temp Tables - can't use these because it would cause a large hit on system performance due to the frequency SP2 and others like it will be used.
Functions - My last resort is to use a table valued function as shown:

FUNCTION MyFunction
( )
RETURNS @retTable
(
@Field1 int,
@Field2 varchar(50)
)
AS
BEGIN
-- the problem here is that I need to call SP1 and assign it's resulting data into the
-- @retTable variable

-- this statement is incorrect, but it's meaning is my goal
INSERT @retTableSELECT *FROM SP1

RETURN
END

Transact SQL :: Return Set Of Values From SELECT As One Of Return Values From Stored Procedure

I have a stored procedure that selects the unique Name of an item from one table. 

SELECT DISTINCT ChainName from Chains

For each ChainName, there exists 0 or more StoreNames in the Stores. I want to return the result of this select as the second field in each row of the result set.

SELECT DISTINCT StoreName FROM Stores WHERE Stores.ChainName = ChainName

Each row of the result set returned by the stored procedure would contain:

ChainName, Array of StoreNames (or comma separated strings or whatever)

IDENTITY Values In A Stored Procedure

Oct 18, 2005

Hi All,
This is my stored procedure

CREATE PROCEDURE testProc AS
BEGIN
CREATE TABLE #tblTest(ID INT NOT NULL IDENTITY, Col1 INT)
INSERT INTO #tblTest(Col1)
SELECT colA FROM tableA ORDER BY colA

END


This is my simple procedure, I wanted to know whether the IDENTITY values created in #tblTest will always be consistent, I mean without losing any number in between. i.e. ID column will have values 1,2,3,4,5.....
or is there any chance of ID column having values like 1,2, 4, 6,7,8....

Please reply...

Here the itemid field in DtTable is of type int. Now when i execute the produre it is showing error as the Itemid is int and i am passing a string value to it.
