Hi,Using Chandu Thota's book Mappoint.net I attempted to set up a findnearby query using his example Implementing Spatial Search Using SQL Server.
The book uses C# I have attempted to convert the code to call the stored procedure as follows:
TryDim units As Int16 = 0
Dim cmd As SqlCommand = New SqlCommand("FindNearby")
'Assign input values to the sql command
cmd.CommandType = CommandType.StoredProcedurecmd.Parameters.AddWithValue("@CenterLat", latitude)
cmd.Parameters.AddWithValue("@CenterLon", longitude)cmd.Parameters.AddWithValue("@SearchDistance", distance)
cmd.Parameters.AddWithValue("@Units", units)Dim con As New Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("VehicleMarshallConnectionString").ConnectionString)
If con.State = ConnectionState.Closed Then con.Open()
If con.State = ConnectionState.Open Then
cmd.Connection = conDim dreader As SqlDataReader = cmd.ExecuteReader()
If dreader.Read() Then
If Not dreader.IsDBNull(1) ThenDim ordnum As String = dreader(1).ToString
End If
End If
End IfIf con.State = ConnectionState.Open Then con.Close()
Catch ex As Exception
Finally
End Try
The code returns no values but when I execute the stored procedure from the server explorer in visual studio I get the records I would expect in the output window. How would I read the returned values from my code.
Output Window
Running [dbo].[FindNearby] ( @CenterLat = 53.10531, @CenterLon = -2.4769, @SearchDistance = 100, @Units = 0 ).
ID ordnum ProxDistance
----------- ------------------------- -------------------------
1 009999/USP 0
2 109999/USP 14.5971373147639
3 119999/USP 57.7144756947325
No rows affected.
(3 row(s) returned)
@RETURN_VALUE = 0
Finished running [dbo].[FindNearby].

I have a package that I have been attempting to return a error code after the stored procedure executes, otherwise the package works great.
I call the stored procedure from a Execute SQL Task (execute Marketing_extract_history_load_test ?, ? OUTPUT)
The sql task rowset is set to NONE. It is a OLEB connection.
I have two parameters mapped:
tablename input varchar 0 (this variable is set earlier in a foreach loop) ADO.
returnvalue output long 1
I set the breakpoint and see the values change, but I have a OnFailure conditon set if it returns a failure. The failure is ignored and the package completes. No quite what I wanted.
The first part of the sp is below and I set the value @i and return.
CREATE procedure [dbo].[Marketing_extract_history_load_TEST]
@table_name varchar(200),
@i int output
as
Why is it not capturing and setting the error and execute my OnFailure code? I have tried setting one of my parameter mappings to returnvalue with no success.

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?

Hi
I have decided to approach the problem here
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=103310
by using a Stored procedure, someone mentioned it's possible
for a SP to read the contents of a text file ?
IS it ?
For example i have a DB table
with fields to,from,subject,body
problem is the body field references a file (full path)
and i need to extract all info into a txt file
the full txt body, so can i perform some sort of inner
operation on the select body .. part of the SP ?

I have a stored procedure that selects the unique Name of an item from one table.Â
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)
How can I code a stored procedure to do this?

Problem Description:
Stored Procedure hanging when try to execute in READ_ONLY Database. Though the stored procedure is highly complicated,it runs smoothly on the same server if the Database option is set to READ/WRITE. Not all stored procedures are hanging in READ_ONLY database,only if the stored procedure tries to retrieve more records (say 10000 ).
If the SQL Statements present inside the stored procedures are executed,they are getting executed perfectly but hangs if it is executed as stored procedure.
On restarting the SQL Server, stored procedure getting executed only for the first time in READ_ONLY database but executing it again for the second time, it starts hanging. ( I tried executing the stored procedure after clearing the procedure cache but still hangs ).
Environment:
Windows NT 4.0 (Service Pack 5 )
SQL Server 7.0 ( Service Pack 3 )
Multi Processor ( 2 - 500 Mhz )
Let me know if you need more information on it.

In a stored procedure, I am trying to create a table and then read it from within that SP or from another one (nestsed). When I run the below code (simplified version of my real SP), no records are returned even though I know that there is data. The table is created and records are inserted, I just cannot read the records from the SP or one that calls it with an EXEC.
Any ideas? My code is listed below. (When I get this to work, I plan to convert the code to manipulate a temporaty table).
Alter Procedure spWod_rptWoStatusSummary_9
As
BEGIN
CREATE TABLE tblStatusSummary (TckStaffCd_F Char(3), RecType Char(20))
INSERT INTO tblStatusSummary
SELECT TckStaffCd_F, RecType
END
BEGIN
Select * from tblStatusSummary
end

Hi guys I know this is a really common question, and I have read loads of replies on it but everything I try does not work. I have written a small stored procedure in SQL server to upload images to a table and return the new ID using scope_identity. I have tested it and it works fine. here it is:******* @siteID numeric(18,0), @imgNum numeric(18,0), @title NVarchar(50), @MIMEtype nchar(10), @imageData varbinary(max)ASBEGINSET NOCOUNT ONdeclare @imageID intINSERT INTO [site_images] ([img_siteID], [img_num], [img_title], [img_MIME], [Img_Data]) VALUES (@siteID, @imgNum, @Title, @MIMEType, @ImageData) SET @imageID = SCOPE_IDENTITY()RETURN @imageIDSET NOCOUNT OFF************If I run this in management studio express it runs fine and returns the ID under 'return value'. The problem I have is trying to actually call that return value in VB. If I try using these lines:Dim returnParam As SqlParameterreturnParam = New SqlParameter("@imageID", SqlDbType.UniqueIdentifier)returnParam.Direction = ParameterDirection.OutputcmdTest.Parameters.Add(returnParam)withcnBKTest.Open()cmdTest.ExecuteNonQuery() imageIDparam = returnParam.value.toStringcnBKTest.Close() I get the error "procedure has too many arguments specified"And if I try to access the return value like this: imageIDparam = cmdTest.Parameters("@return_value").ValueI get the error "@return_value is not contained by this sqlparametercollection" What am I doing wrong? Any help would be greatly appreciated. Robsa

Hi all,Is there anyway to get a returned value from a called Stored Procedure from within a piece of SQL? For example, I have the following code...DECLARE @testval AS INTSET @testval = EXEC u_checknew_dwi_limits '163'IF (@testval = 0)BEGIN PRINT '0 Returned'ENDELSEBEGIN PRINT '1 Returned'END...which
as you can see calls a SP called 'u_checknew_dwi_limits'. This SP
(u_checknew_dwi_limits) actually returns a value (1 or 0), so I want to
assign that value to the '@testval' variable (as you can see in my
code) - but Query Analyser is throwing an error at me. Is this the
correct way to do this?ThanksTryst

I have a Stored procedure (sql 2000), that inserts data into a table. Then, I add this, at the end: Return Scope_Identity()
I have the parameters for the sProc defined and added to the Command, but I'm having a really lousy time trying to figure out how to get the return value of the Stored PRocedure. BTW - I'm using OleDB instead of SQL due to using a UDL for the connection string.
I have intReturn defined as an integer
I've tried :Dim retValParam As OleDbParameter = cmd.Parameters.Add("@RETURN_VALUE", OleDbType.Integer)retValParam.Direction = ParameterDirection.ReturnValueintReturn=cmd.Parameters("@RETURN_VALUE").Value
whenever I add this section - I get an error that there are too many arguments for the sProc.
I've tried:intreturn=cmd.ExecuteNonquery - tried adding a DataReader - using ExecuteScalar - I've tried so many things and gotten so many errors - I've forgotten which formations go with which errors.
What is the best way to do this in the code part (VB.Net)?
Thanks ahead of time

I don't know whey this code does not return the values when I run it in sql server 2005 manager.set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
ALTER PROCEDURE [dbo].[usp_usr_Add]

@LName nvarchar(30),
@UserName nvarchar(20),

DECLARE @usrID int
DECLARE @usrEmail int
SELECT @usrID = NULL
SELECT @usrEmail = NULL
SELECT @usrID = usrID FROM usr WHERE usrName = @UserName
IF (@usrID IS NOT NULL )
BEGIN
RETURN 1
END
SELECT @usrEmail = usrID FROM usr WHERE usrEmail = @Email
IF (@usrEmail IS NOT NULL)
BEGIN
RETURN 2
END
INSERT INTO usr (usrFName, usrLName, usrName, usrPassword, usrEmail, usrCountry, usrAIM, usrJoinDt)
VALUES (@FName, @LName, @UserName, @Password, @Email, @Country, @AIM, GetDate())
RETURN 0
END
When i run this code i executes fine except when the two conditions become true they do not return thier values, nor does it return 0 when it inserts a row.

In one of my SSIS jobs I have an 'Execute SQL Task' which is calling a stored procedure. This SP returns 0 or 1, if the SP returns 1 the package needs to stop executing. Is there a way to get the value that is returned from the SP and either continue or stop the job from continuing to run?
so if value is 0 it goes to the next step, if its 1 it stops running

Greetings All,
I am a newbie to SSIS and need some help. I need to get the return value from a stored procedure into a SSIS variable. I'm assuming I would use an OLE DB Command but I havn't a clue on how to capture the return value. Can someone get me started on how I can do this?
Note, the return value is actually an identity of the inserted value. I need this value in my data flow for further processing.
Thanks is advance!

Hi
I was wondering how I could pass on the following parameters from an ini file to a stored procedure within a DTS package. The parameters in the ini file look like:
[DatabaseCleaner]
! -- TableToBeCleaned_N=<table name>,<months to hold on db>,<months to hold on hd>
! -- <N> must be a successive number starting from 1 ...
TableToBeCleaned_1=Transactions,24,24
TableToBeCleaned_2=Payments,24,24
TableToBeCleaned_3=PresenceTickets,24,24
As I do not know how many tables that will be declared in the ini file I have to loop through until the last parameters and pass it over to the SP.
How can I do that? Any idea?
Thanks

In general as understand if we have a stored procedure that does operations like inserts or updates, it makes perfect sense to use a rollback operation within a transaction.
So, if something goes wrong and the transaction does not complete, all changes will be reverted and an error description will be thrown for example.
Nevertheless, does using a rollback within a try catch statement, make sense in a read only stored procedure, that practically executes some dynamic sql just to select data from some tables?
I have around 100 Stored procedures, all of them read only. Today a colleague suggested adding try-catch blocks with rollback to all of them. But since they are just selecting data, I don't see a clear benefit of doing so, compared to the hassle of changing such a big number of SP's.

I am have stored procedure that accepts one parameter and returns a single value
The sp works fine.
My question is how do I set the c# webpage to return the single value.
I need a specific example of how to code.
this is how the code should work.
A blank form is loaded, when the user clicks submit I need the code to pull the Login name from the text box and check to see if it exist. I have the sp working the way I need it to. But I can figure how to pull the single value into a variable in the code behind.
I am using dataset elsewhere on the site, so I created a ds the calls the sp. Can it work this way?
thanks,
