Output Parameters From An SqlDataSource
Feb 21, 2008Hi all,
I have a stored procedure which sets an output variable. How could I access this after calling an SqlDataSource.Select()?
Thanks

Using SqlDatASource Programmatically - Output Parameters
May 13, 2006I am using SqlDataSource programmatically in my data access layer - mainly for convenience but it does generally work fine with no obvious performance issues.
The problem I have is with getting back an output parameter. I have an insert-type stored procedure (in Sql Server 2005) operating on a table with an identity column as the primary key:
ALTER PROCEDURE [dbo].[InsertAlbum](@ArtistID int, @Title nvarchar(70), @NewID int OUTPUT)ASDECLARE @err intINSERT INTO dbo.ALBUMS (ARTISTID, TITLE)VALUES (@ArtistID, @Title)SELECT @err = @@error IF @err <> 0 RETURN @errSET @NewID = SCOPE_IDENTITY()
This works fine when run from Sql Server Management Studio and @NewID has the correct value.
My data access code is roughly as follows:
dsrc = New SqlDataSource()dsrc.ConnectionString = ConnectionStringdsrc.InsertCommand = "InsertAlbum"dsrc.InsertCommandType = SqlDataSourceCommandType.StoredProcedureDim parms As ParameterCollection = dsrc.InsertParametersDim newid As IntegerAddParameter(parms, "ArtistID", TypeCode.Int32, ParameterDirection.Input, 0, album.ArtistID)AddParameter(parms, "Title", TypeCode.String, ParameterDirection.Input, 0, album.Title)Dim p As New Parameter("NewID", TypeCode.Int32)p.Direction = ParameterDirection.Outputparms.Add(p)Try Dim rv As Integer = dsrc.Insert() newid = parms("NewID") Return newidCatch ex As Exception Return -1End Try
The row is inserted into the database, but however I try to define and add the NewID parameter it never has a value.
Has anyone tried to do this and can tell me what I am doing wrong?

Deleted Event On Sqldatasource And Output Parameters... Always NULL!!
Apr 18, 2007I have an event:
Private Sub SqlDataSourceIncome_Deleted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles SqlDataSourceIncome.Deleted
Dim command As SqlClient.SqlCommand
command = e.Command
If command.Parameters("@nReturnCode").Value <> 0 Then
DROPDEAD()
End If
That fires from:
<DeleteParameters>
<asp:Parameter Name="nDeletebyId" Type="Int64" />
<asp:Parameter Name="nOtherId" Type="Int64" />
<asp:Parameter Direction="Output" Name="nReturnCode" Type="Int64" />
<asp:Parameter Direction="Output" Name="nReturnId" Type="Int64" />
</DeleteParameters>
End Sub
When I:
GridViewIncome.DeleteRow(GridViewIncome.SelectedRow.RowIndex)
But nReturnCode is ALWAYS NULL... I even did a stored procedure that just:
ALTER PROCEDURE [dbo].[sp_nDeletebyId]
@nReturnCode bigint output,
@nReturnId bigint output AS
SET @nReturnCode = 0
SET @nReturnId = 0
And STILL got nothing but the NULLS... the insert & update stuff works fine, with identical code... it's just the DELETED event that I can't seem to knock. Has anyone seen this before? The above sample stored proc did return 0 when executed one the server...
and, BTW, the row is deleted!

Transact SQL :: Generic Store Procedure Call Without Output Parameters But Catching Output
Sep 21, 2015Inside some TSQL programmable object (a SP/or a query in Management Studio)I have a parameter containing the name of a StoreProcedure+The required Argument for these SP. (for example it's between the brackets [])
EX1 : @SPToCall : [sp_ChooseTypeOfResult 'Water type']
EX2 : @SPToCall : [sp_ChooseTypeOfXMLResult 'TABLE type', 'NODE XML']
EX3 : @SPToCall : [sp_GetSomeResult]
I can't change thoses SP, (and i don't have a nice output param to cach, as i would need to change the SP Definition)All these SP 'return' a 'select' of 1 record the same datatype ie: NVARCHAR.

SqlDataSource SQL Generation Output On Errors?

control is generating. I am having a difficult time diagnosing
errors such as the following:
Keyword not supported: 'unicode'.
Any help is appreciated.
SqlDataSource Parameters
Apr 4, 2007Is
it possible to specify different parameters for the
select/update/delete stored procedures used by a sqldatasource? When I
'configure the datasource' it lists the different stored procedures for
each command, but when it comes to specifying the parameters it only
lets me do so for the select command. Is there another way to do this
for the other commands?
I have tried doing it manually in the aspx file (using the
DeleteParemeters etc), but I don't know how to reference a specific
cell in the selected row of the gridview for the controlparameter). Any
thoughts?
Parameters Of SqlDataSource
Apr 17, 2007Hello I need help withsetting parameters for SqlDataSource
I have a simple program. I want display date from database on MS SQLSERVER from the table USERS only for current sing on user select by his login.
I save into this variable login current user: string @LOGIN = Context.User.Identity.Name;
I have already done with this way without SqlDataSource:
string login = Context.User.Identity.Name;
SqlConnection conn1 = new SqlConnection("server=CR\SQLEXPRESS;database=myData;integrated security=SSPI");
conn1.Open();
SqlCommand cmd1 = new SqlCommand(" SELECT IN_OUT.TIME_START, IN_OUT.TIME_END, FROM IN_OUT INNER JOIN USER ON USER.USER_ID=IN_OUT.RC_USER_ID where USER.LOGIN=@LOGIN", conn1);
cmd1.Parameters.Add("@LOGIN", SqlDbType.NVarChar, 50);
cmd1.Parameters["@LOGIN"].Value = login;
1.Parameters.Add("@LOGIN", SqlDbType.NVarChar, 50);
cmd1.Parameters["@LOGIN"].Value = login;
Now I don't know how to do with SqlDataSource, what I have to set in SqlDataSource1 yet
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:myConnectionString %>"
ProviderName="<%$ ConnectionStrings:myConnectionString.ProviderName %>" SelectCommand="SELECT IN_OUT.TIME_START, IN_OUT.TIME_END, FROM IN_OUT INNER JOIN USER ON USER.USER_ID=IN_OUT.RC_USER_ID where USER.LOGIN=@LOGIN">

View 3 Replies View RelatedSQLDataSource: How To Use Parameters
Dec 22, 2005I need to do some select & update from VB code behind a web page. Using VS2005, ASP.NET.
To me, the most logical approach would be to use a SqlDataSource. I can select the connection string, predefine select, insert and update queries and call the select(), and other commands from this control.
I need to use parameters in the queries but I cannot connect parameters straight to controls, I need to do it from VB. But nowhere can I find how to set the parameter values from code. I can find all kind of examples from VS2003 or using SqlCommand, but it should be possible from this control as well, but the help documentation is very poor in this respect.
Please provide me with some example.
Kind regards
Issues With An Output Param From A Sproc Using SQLDataSource
Nov 28, 2007I have a stored proc that I'd like to return an output param from. I'm using a SQLDataSource and invoking the Update method which calls the sproc.The proc looks like this currently:
ALTER proc [dbo].[k_sp_Load_IMIS_to_POP_x]@vcOutputMsg varchar(255) OUTPUT
AS
SET NOCOUNT ON ;
select @vcOutputMsg = 'asdf'
The code behind looks like this:protected void SqlDataSource1_Updated(object sender, SqlDataSourceStatusEventArgs e)
{
//handle error on return
string returnmessage = (string)e.Command.Parameters["@vcOutputMsg"].Value;
}
On the page source side, the params are defined declaratively:
<UpdateParameters>
<asp:Parameter Direction="ReturnValue" Name="RETURN_VALUE" Type="Int32" />
<asp:Parameter Direction="InputOutput" Name="vcOutputMsg" Type="String" />
</UpdateParameters>
When I run it, the code behind throws the following exception - "Unable to cast object of type 'System.DBNull' to type 'System.String'"
PLEASE HELP! What am I doing wrong? Is there a better way to get output from a stored proc?
SqlDataSource Setting Of Parameters?

Nov 29, 2007Hello!
I am pulling my hair out over this latest problem. I'm trying to do a simple SQL SELECT statement by taking values from textboxes and inserting them into the WHERE part of the statement. I'm using MySQL and have to use ? prefix for all inserts, that I have working by the way. Now for some reason I cannot get the values from the text boxes to replace the prefixes! Here is my code:
private void submitLogin(object source, EventArgs e) {
if (isPassword(password.Text.ToString()) && isEmail(username.Text.ToString()))
{
ValidateCustomer.SelectParameters["c_email"].DefaultValue = "fish";
ValidateCustomer.SelectParameters["c_password"].DefaultValue = "cakes";
test_label.Text = ValidateCustomer.SelectCommand.ToString();
}
else {
test_label.Text = "Username or Password Incorrect";
}
}
<asp:SqlDataSource runat="server"
ID="ValidateCustomer"
ProviderName="System.Data.Odbc"
ConnectionString ="<%$ connectionStrings:MySQLDatabase %>"
SelectCommand ="SELECT * FROM customer_details WHERE (Customer_Email = ? AND Customer_Password = ?)">
<selectparameters>
<asp:parameter name="c_email" type="String" />
<asp:parameter name="c_password" type="String" />
</selectparameters>
</asp:SqlDataSource>
I have omitted obvious code. The test label, when updated, shows the SQL statement but with the ?. I also use controlparameters that took the values directly from the textboxes but again this did not work. I'm really stuck with this one. Your help is much needed!

SQLDataSource Parameters Question
Apr 10, 2006Can you access the values within sqldatasource parameters
programmatically? I have tried to reference them in the following
ways without any luck.

-SqlDataSource_Contacts.UpdateParameters("original_user_id").ToString
-SqlDataSource_Contacts.UpdateParameters("original_user_id").DefaultValue
-SqlDataSource_Contacts.UpdateParameters("original_user_id").DefaultValue.ToString
-SqlDataSource_Contacts.UpdateParameters.Item("original_user_id")
-SqlDataSource_Contacts.UpdateParameters.Item("original_user_id").ToString
-SqlDataSource_Contacts.UpdateParameters.Item("original_user_id").DefaultValue
-SqlDataSource_Contacts.UpdateParameters.Item("original_user_id").DefaultValue.ToString
Programmatically Specify SqlDataSource Parameters
Apr 27, 2006I have a GridView bound to a SqlDataSource. On page load I would like to programmatically specify a SelectParameter value based on the role of the user. This SelectParameter will be used in my WHERE clause. The closest post I can find is http://forums.asp.net/thread/1233258.aspx but no answer was posted.
What code would I use to modify a SelectParameters value? Is it possible to reference a parameter by name (SqlDataSource1.SelectParameters["usertype"]) or does it have to be by index? (SqlDataSource1.SelectParameters[0])
Alternatively, perhaps I'm going about this in the wrong way, is there a better way to have dynamic GridView content based on the role of the user?
Thank you very much for your help.
Problem With Output Parameter From Stored Procedure Using SqlDataSource
Nov 23, 2005I am having a problem getting the output parameter from a stored procedure that deletes a record. I use the EXACT same process for the insert and update procs and they work fine. For some reason, the delete proc is either not returning an output parameter, or the SqlDataSource (dsCompany) is not able to get the information in the dsCompany_Deleted method. I simply want the proc to return an output value so that when I eventually get around to checking if the record can be deleted due to foreign key restraints, I can deliver the appropriate message to the user.I have highlighted the line that is giving the problem. I also highlighted a default value in the parameter, that when removed causes the app to crash because it is getting a null value back. Thanks in advance to anyone who can help!STORED PROC (eventually I will add foreign key restraints)

SQLDataSource Update Using Parameters Not Working
Jul 10, 2006I'm passing a parameter to a stored procedure stored on my sqlserver, or trying to atleast. And then firing off the update command that contains that parameter from a button. But it's not changing my data on my server when I do so.
I'm filling a dropdown list from a stored procedure and I have a little loop run another sp that grabs what the selected value should be in the dropdown list when the page loads/refreshes. All this works fine, just not sp that should update my data when I hit the submit button.
It's supposed to update one of my tables to whatever the selected value is from my drop down list. But it doesn't even change anything. It just refreshes the page and goes back to the original value for my drop down list.
Just to make sure that it's my update command that's failing, I've even changed the back end data manually to a different value and on page load it shows the proper selected item that I changed the data to, etc. It just won't change the data from the page when I try to.
This is what the stored procedure looks like:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ALTER PROCEDURE [dbo].[UPDATE_sp] (@SelectedID int) AS
BEGIN
UPDATE [Current_tbl]
SET ID = @SelectedID
WHERE PrimID = '1'
END

Using One SqlDataSource For Many DropDownLists, But Ability To Set Parameters?
Jan 3, 2007If I have a lot of dropdowns of similar type but only differ in one field, is there a way to set parameters so that the dropdownlist can specify what the parameter values are?
For example dropdowns: expenseaccount, incomeaccount, assetaccount
SqlDataSource:
SelectCommand="select accountid,accountname from accounts, accounttypest where accounts.accounttypeid=acounttypes.accounttypeid and accounttypes.accounttypename=? order by accountname"
<SelectParameters>
<asp:Parameter Name="accountTypeName" Type="string" />
</SelectParameters>
-------
I would like expenseaccount to be able to specify "EXPENSE", incomeaccount to specify "INCOME", etc...
Or is sqldatasource reusage bad practice?

My stored procedures are tested and verified and the parameter names are the same as the source columns. When I try to run the delete an error that the stored procedure expects the parameter @locationStationId, however this value passes properly for the Update command?!? I tried to change the parameter to original_locationStationID to pass the original value, however this result in Null being passed for the parameter.
I cannot understand why this works for Update and passes the location ID, but will not work for DELETE. Can anyone shed any light onto the matter?
Thanks.OldValuesParameterFormatString="original_{0}" UpdateCommand="spUpdateLocation" UpdateCommandType="StoredProcedure"
DeleteCommand="spDeleteLocation" DeleteCommandType="StoredProcedure">
<DeleteParameters>
<asp:Parameter Name="locationStationId" Type="String" />

Setting Command Parameters For SQLDataSource
Dec 26, 2007I have an SQLDataSource. The SQL is
SELECT UserName, Category, ItemDescription, Size, Price, Reduce, Donate, Sold, ItemNumber, SoldDate, SoldPrice, PrintedFROM Tags WHERE (Printed = @Printed1 OR Printed = @Printed2 OR Printed = @Printed3) ORDER BY ItemNumber DESCThe bit field "printed" can be NULL, True or False.In the Selecting event of the SQLDataSource I have the following to show ALL records. But it does not work. If I remove these parameters it show ALL records.
e.Command.Parameters("@Printed1").Value = Nothing 'ASP.NET 2.0 using Visual basice.Command.Parameters("@Printed2").Value = Truee.Command.Parameters("@Printed3").Value = False
What am I doing wrong???

Dynamically Adding New Parameters To SQLDataSource
Dec 28, 2007CancelSelectOnNullParameterHi,Suppose I have a SQLDataSource with a
SelectCommand="SELECT * FROM STOCKS WHERE USER=@USER ORDER BY STOCK_NAME"
and @USER is set as a session parameter. No problem till this part, but in some postbacks, I wish to add a new WHERE criteria to my SQL, so I do:DSSQL.SelectParameters.Add("@STOCK_NAME", "ABC123");
DSSQL.SelectCommand = DSgvStoklar.SelectCommand.Replace(" ORDER BY ", " AND STOCK_NAME LIKE @STOCK_NAME+'%' ORDER BY ");
gridViewDS.DataBind();
and wish that my SelectCommand is modified and a new parameter is added.
The SQL is modified, however -I guess- new parameter is not added, so I get "Must declare the scalar variable "@STOCK_NAME" error.
How can I solve, any ideas?
Stored Procedure Parameters In SQLDataSource
Jan 19, 2008I want to know how to set parameters for Update Stored Procedure in SQLDataSource
Setting SqlDatasource Parameters From TextBox
Feb 17, 2008I have a sqlDatasource with 3 parameters based on the input of 3 text boxes on the page. The datasource returns sales details for a company based on a from and to date. I am attempting to set the value of the 3 parameters in the Selecting event of the datasource control but I'm not getting any data back. If I set the values literally then I get data back. Also when I step through the code I can see the 3 parameters getting their values from the textboxes and the drop down list as they should. This is driving me insane as I'm new to .net and just can't see what is stopping me retrieving the data when using the form fields to set the datasources parameters. Below is the aspx and the code behind for the page.

Need To Increment Numeric Parameters With SqlDataSource- Help!
May 15, 2008hi,
i am using a sqldatasource with a formview that has three stored procedures associated with it. when i update a record in my formview, i need to increase two parameters that are displayed as labels in the formview by their value plus one.
i can't figure out how to increase the value in the stored procedure, or using the codebehind, or with some script in the html. any solution works for me. any suggestions?
if i can figure out how to increment one of my fields, i can use the same logic for the other. below is an example of what i am trying to do.
in my formview i have three fields: Count, Rate, Price. Count is a label, Rate and Price are editable textboxes. once i commit the update for the values of Rate and Price, i need the value of Count to increase by 1, and then have that value updated in the data base along with the new values for Rate and Price.
is there a way to do this in the codebehind, or in my stored procedure?
i am using Asp.Net 2.0, vs2005, and sql server.
any help is greatly appreciated. thank you.
SQLDatasource, Stored Procs && Parameters
Mar 1, 2006 Hi,
I'm having an issue trying to send parameters to a SQLDatasource object. I"m creating it in code (and I need it to stay there) I have determined that the stored procs called with no parameters work fine. I start having problems when I have any parameters. Interestingly, it doesn't crash. It just fails to run (the onselected event never fires).
dsUser is a protected SQLDatasource property
repMain is a repeater on the aspx sheet
lstUser is a stored proc with one varchar(10) parameter called cSort
Here is my current code that will result in no called to StatementCompleted and no data. Pull cSort parameter from the proc and it works just fine. Obviously I'm setting it wrong.
string cSelect = "dbo.lstUser";
dsUser = new SqlDataSource();
dsUser .ConnectionString = GetConStr();
dsUser .SelectCommand = cSelect;
dsUser .SelectParameters.Add( "cSort", TypeCode.String, "" );
dsUser .Selected += StatementCompleted;
repMain.DataSource = dsUser ;
TIA,

View 7 Replies View RelatedSQLDatasource && Schema Refreshing (with Parameters)
Apr 9, 2006Hi,
I'm having serious issues trying to refresh a schema in a SQLDatasource. It is hooked to a stored procedure that takes two varchar(39) parameters. The default parameters in this case are '%'. Note I am working in the designer.
If I set it up as a stored proc, I can't even get the 'test query' to run in the builder.
If I set it up as a select statement, ala 'exec <procname> @p1, @p2', the 'test query' will run.
In neither case will hitting refresh schema work. It returns 'Invalid length parameter passed to the substring function'
The stored proc is nothing special, simply returning a select based upon the parameters.
Thanks,
Nick H
