DeleteCommand, Stored Procedures, And ReturnValue Parameters = Can't Be Done?
Apr 18, 2007
I've a SqlDataSource control that has stored procedures specified for each of its commands: SelectCommand, InsertCommand, UpdateCommand, DeleteCommand . And for Insert, Update and Delete, I've specified asp:parameters for each stored procedure's parameters. Now, my stored procedures all have return values, and I've successfully accessed the return values for Insert and Update, but for some reason, I'm getting very wrong results for Delete. <DeleteParameters>
<asp:Parameter Name="result" Type="Int32" Direction="ReturnValue" />
<asp:Parameter Name="myID" Type="Int32" />
</DeleteParameters>
The moment I add my "result" with the direction ReturnValue, I instantly get a "Procedure or function <storedprocedurename> has too many arguments specified." error. I checked my SQL Profiler, and it seems that the page is passing result as an Input parameter, instead of keeping it as a ReturnValue! e.g.
exec spName @myID=1, @result=NULL
when it should be
exec spName @myID=1
I get the correct behavior with Update and Insert, so I'm wondering whether if this is a bug or by-design behavior or something very screwy with my computer?
Help? Thoughts?

I have the following Stored Procedure:
<code snippet>
UPDATE TRW_USERS
SET user_password = @password
WHERE (user_password = @old_password) AND (user_id = @user_id);
RETURN @@ROWCOUNT
Which when run, returns the correct values 0 if no rows updated 1 if row updated
In my C# I am doing the following:
TRW_USERSTableAdapter userAdapter = new UsersTableAdapters.TRW_USERSTableAdapter();
returnValue = Convert.ToInt32(userAdapter.sp_NewUpdatePassword(sNewHashedPassword, sOldHashedPassword, user_id));
It always returns 0 to returnValue, why?
Many thanks

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

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

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!

I use a stored procedure that is calling several other stored procedurewhich update or append values in several tables. All of them are storedprocedures with input parameters by which they filter rows to be updated orinserted into other tables.Filtration is based on certain actual values on forms (form with severalsubforms).My question is following: How to pass parameters to those stored proceduresthat are triggered by a button?Those stored procedures are not recordset of forms, so I can't pass it usingInput Parameters property of forms (or I can?).Thanks.Zlatko

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!!
Thanks in advance for any of your thoughts

How can I pass a name of a table to a stored procedure.
I want to pass the name as a parameter. The table already exists in the db.
After that, I will do
"SELECT .....

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
FROM PRODUCT
WHERE @Field LIKE @Value
ORDER BY DIV_NO, LN_NO, ITM_NO

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.

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.

Hi,
I was just wondering if something could be explained to me.
I have the following:
1. A table which has fields with data types and lengths / sizes
2. A stored procedure for said table which also declares variables with datatype and lengths/ sizes
3. A function in written in VB .net that uses said stored procudure. The code used to add the parameters to the sql command also requires that i give a data type and size.
How come i need to specify data type and length in three different places? Am i doin it wrong?
Any information is greatly appreciated.
Thanks

I guess I'm the only one with this problem -- couldn't find anything on it in the back questions. Maybe it's a weird problem. :)
Anyway, although I'm not new to SQL, I am a bit new to stored procedures, and MS SQL Server 7. (I've been using mySQL, decent, but doesn't have many features ... )
I used some ASP and stored procedure code from 4guysfromrolla.com for session tracking through SQL Server.
I've modified most of the stored procedures so that they actually work. :)
The tables it uses are simple:
sessions: sessionid (uniqueidentifier), date_stamp (datetime), sessionipaddr(varchar(50))
sessionvalues: sessionid (uniqueidentifier), sessionvalname (varchar(100)), sessionvaldata (varchar(8000))
To answer some questions before they're asked: It's a resume database, and does need to be able to store 8000 characters at a shot. (I'm hoping 8000 is as large as it gets for this particular field.)
There's only one problem now: One of the stored procedures enters information into the sessionvalue field of the table. However, much of our data contains apostrophes ('), and we need to be able to store them. I thought that modifying the execute statement would do it, something like:
EXECUTE sessiondata '{EC8131F6-409A-11D4-8E88-00A0C9E4F36E}', 'ExpWorkDescs', 'Here' + CHAR(39) + "s some data"
This doesn't work. Indeed, even if the concatenation worked, CHAR(39) doesn't in this context.
Then I thought I'd be really clever, and try a trick from mySQL:
EXECUTE sessiondata '{EC8131F6-409A-11D4-8E88-00A0C9E4F36E}', 'ExpWorkDescs', 'Here's some data'
Naturally, that one didn't work, either. (That was a long shot, admittedly!)
This is mission-critical. Not only apostrophes, but quotes and other punctuation marks must be able to be transferred. Anyone know a way to do it?

Hi,
When I execute a stored procedure from an OLE DB Command transformation, where the sp takes a parameter and RetainSameConnection=TRUE and DelayValidation=TRUE are set, I get the error
"Syntax error, permission violation, or other nonspecific error"
If I take out the param or set RetainSameConnection=FALSE on the connection, all is fine again?
Has anyone has come across this?

I am learning T SQL and SQL queries and have limited VB knowledge, and have a some simple queries to run on a table with parameters, and would like verification of the proposed methodology and suggestions.
Simply put, I have a [Transactions] table with columns [Price], [Ticker], [TransDate], [TransType] and calculated columns for [Days] and [Profit].
There are two parameters, [@Dys] (to query a the table for transactions within a certain period[Days = 30] and [@TT] to query only the closed transactions ie... [TransType='C']
I have been studying Stored Procedures and will be writing a Stored Procedure, but need verification if the following will work... Getting the SUM and AVG calcluations for the fields above is not a problem but I need to display SUM and AVG information also for those transactions where [Profit >0] and [Profit <0], which is easy enough by creating a subquery. But the problem is:
1. If I use a SubQuery for [Profit <0] and for [Profit>0], can I create an alias for [Count(*)] (to get a row or transaction count for each, and then divide that into the Total [Count(*)] alias for the Transactions table to get a value for % profitable or Probability (% total Profitable trades versus % total Unprofitable trades)?
2. Or, do I need to create either temporary tables or views to have 3 distinct tables (1 table for Transactoins and 2 temp or Views for [Profit >0] and [Profit <0])?
Any suggestions and advice or examples on how to do this would be appreciated.

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

I've created a search page in my asp.net app that allows the user to enter optional parameters to narrow down the result set. It looks something like:Find all parts where: manuafacturer: <dropdownlist>ANY | manufacturer 1 |... </dropdownlist> model: <dropdownlist>ANY | model 1 |... </dropdownlist> cost: between <textbox> and <textbox> dollarsCurrently I create the SQL command on the fly building the WHERE based on what the user selects. For example if in the form above they select manufacturer = manufacturer1 model = ANY cost = between 10 and 15the WHERE string is ... WHERE manufacturer='manufacturer1' AND cost BETWEEN 10 AND 15Since the user doesn't care about model I leave it out of the WHERE. OK so here is my question. I want to move my queries to strored procedures however I'm not sure how to create the query since it changes based on what the user enters. Using the example above I'm assuming I can create one query with 4 parameters however what value would I use for ANY? parameter1 (manufacturer) = "manufacturer1" parameter2 (model) = ??? parameter3 (price low) = 10 parameter4 (proce high) = 15I see there is an ANY operator in T-SQL but it doesn't look like the right thing to use. Should I use LIKE '%'? Seems that using LIKE would result in addition overhead.ThanksSimon

Is there a way to combine 2 stored procedures with a different set off parameters.
Basically my 1st stored procedure has the following parameters:
1.@PlanID
2.@FinancialYearID
3.@RangetypeID
My second stored proc has the following:
1.@FinancialYearID
2.@IndicatorID
3.@VersionID
I have researched and so far nothing seems to be working. There is a conflict between the FinancialYearID of the 1st and 2nd stored procs.
My overall result is the combination of the 1st and 2nd storedprocs in 1.

Hi everyone
I have just starting creating some stored procedures for our system and have a question related to management of these.
When using input parameters using the following syntax:
CREATE PROCEDURE sp_someInputProcedure
@Username as varchar(16)
@Password as varchar(12)
@Name as varchar(50)
@Address as varchar(60)
@Zip as int
@City as varchar(30)
...
etc.
This is all well and good, but what if I make a change in the datamodel - for instance changing a datatype or the length of a varchar - do I need to remember to manually update all stored procedures that uses these columns/variables?
Seems like a bit of a hazzle. Is there an easier way to do this?
Many thanks,

Consider a situation where a stored procedure taking a varbinary(max) (BLOB) input parameter then calls a nested stored procedure and passes along that varbinary(max) as an input parameter to the nested stored procedure.
Is a copy of the BLOB provided to the nested stored procedure (passed by value) OR is the BLOB passed by reference.
My interest is in understanding the potential memory hit when handling large BLOBs in this environment.
For example, if the BLOB is 200MB, will SQL server need to allocate memory for a new copy each time it's passed to another stored procedure?
Looks like table type parameters are passed by reference, but I haven't been able to find any info on BLOBS in this context.

There is a form in an Access Project (.adp, Access front end with SQLServer) for entering data into a table for temporary storing. Then, byclicking a botton, several action stored procedures (update, append) shouldbe activated in order to transfer data to other tables.I tried to avoid any coding in VB, as I am not a professional, but I havefound a statement in an article, that, unlike select queries, form's InputProperty can't be used for action queries. Therefore, parameters can bepassed to action stored procedure only by using ADO through VB.As I'm not very familiar with VB, I had to search in literature.So, this is a solution based on creating Parameter object in ADO and thenappending values to Parameter collection.Please, consider the following procedure I created for passing parametersfrom form's control objects (Text boxes) to a stored procedureDTKB_MB_UPDATE:Private Sub Command73_Click()Dim cmd As ADODB.CommandSet cmd = New ADODB.Commandcmd.ActiveConnection = CurrentProject.Connectioncmd.CommandText = "DTKB_MB_UPDATE"cmd.CommandType = adCmdStoredProcDim par As ADODB.ParameterSet par = cmd.CreateParameter("@DATE", adDBTimeStamp, adParamInput)cmd.Parameters.Append parSet par = cmd.CreateParameter("@BATCH_NUMBER", adVarWChar, adParamInput, 50)cmd.Parameters.Append parSet par = cmd.CreateParameter("@STATUS", adVarWChar, adParamInput, 50)cmd.Parameters.Append parSet par = cmd.CreateParameter("@DEPARTMENT", adVarWChar, adParamInput, 50)cmd.Parameters.Append parSet par = cmd.CreateParameter("@PRODUCTION", adVarWChar, adParamInput, 50)cmd.Parameters.Append parSet par = cmd.CreateParameter("@SAMPLING_TYPE", adVarWChar, adParamInput,50)cmd.Parameters.Append parcmd.Parameters("@DATE") = Me.DATEcmd.Parameters("@BATCH_NUMBER") = Me.BATCH_NUMBERcmd.Parameters("@STATUS") = Me.STATUScmd.Parameters("@DEPARTMENT") = Me.DEPARTMENTcmd.Parameters("@PRODUCTION") = Me.PRODUCTIONcmd.Parameters("@SAMPLING_TYPE") = Me.SAMPLING_TYPEcmd.ExecuteSet cmd = NothingEnd SubUnfortunately, when clicking on the botton, the following error apears:"Run-time error'-2147217913 (80040e07)':Syntax error converting datetimefrom character string."Obviously, there is some problem regarding parameter @DATE. In SQL Server itis datetime, on the form's onbound text box it is short date (dd.mm.yyyy)data type. I have found in literature that in ADO it should beadDBTimeStamp.So, what is the problem ?Greetings,Zlatko

(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
SqlConnection(connectionString)
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.
Thanks in advance,
Scott Chang

I have added a gridview and under its properties i have changed AutoGenerateDeleteButton and AutoGenerateEditButton to true.
The problem is... when I try and delete a record, I get this error: Deleting is not supported by data source 'SqlDataSource1' unless DeleteCommand is specified
If I try and update.. i get the error: Updating is not supported by data source 'SqlDataSource1' unless UpdateCommand is specified.
Can someone please help me out... maybe with some code... or a link to a tutorial..
Thanks
