I'm creating a tool using windows form which needs to retrieve data from an Oracle database configured to use odp.net using an Oracle Stored Procedure. I'm planning to use the code below for some basic testing. The Stored Procedure is made up of a number of OUT parameters, some of which have been mapped using the datatypes available in .NET, however other parameters are defined as tables (I guess lists) and i'm not sure how to access this data
Try
Dim oraConnString As String = "Data Source=*****;User Id=******;Password=******;"
Dim oraConnection As New OracleConnection(oraConnString)
I am working on a Asp.net based project and my requiremnent is to generate a PARTNO with the combination of MaterialType+ProductID and - 4digit random number?
NOTE: ProductID is Primary key and also set it to output parameter for example If material type is 500 and product ID generated 55 and random no generated 5434, then part no become 555-5434 how could I store partno in same table, I am somewhat trying like that

I am retrieving the scope_identity of a db entry, and I want to use that variable in a different SqlDataSource, primarily as an but I am unable to access the variable.I have the variable being displayed in a msgbox, and it is displaying properly, I am just unsure how to access it in the SqlDataSource. Here is my code;This is the datasource that inserts the first information and received the scope_identity, as well as the _inserted event; Code:
ALTER PROCEDURE dbo.uspGetOrderTrackingHeaderInfo @ContractID varchar(9) , @SalesRepID int , @StatusID int , @TypeID int , @StartDate datetime [Code]...
We have an c# class, say we have a following method with out parameterpublic class TestCsharpClass{ public Int32 GetNumber(out bool pbNull){ pbnull=true; return 1; }}tlb file for C# project is generated with regasm tool. The above method is called in vb6 application using callbyName Dim number as IntegerDim objTest as TestCsharpClassdim blnNull as Booleannumber = CallByName(objTest,"GetNumber",VbMethod,blnNull) return value 'Number' is fine.But 'blnNull' boolean variable is "False" always.We were unable to get the out parameter value from C# code.Function signatures are defined in the IDL file.Without changing the function signature is it possible to get the resolution/workaround solution for this issue
I am having a stored procedure in sql 2005 the procedure is to retrieve year code between two days it works correctly in sql query analyzer and it returns value [code]...
I have a sql stored procedure with an output parameter. I'm just trying to read the output parameter in my code and I just cannot get it to work. The error I get is: "Procedure or function 'GetFolderData' expects parameter '@RootName', which was not supplied."
It looks like I am supplying this but it's not working.
Here is my stored procedure:
ALTER PROCEDURE [dbo].[GetFolderData] ( @RootID int,
Here's a simple code snippet of a larger function as an example.
Using conn as New SqlConnection("conn string") Using find as new SqlCommand("ExampleProc",conn) Dim rParam as new SqlParameter("@RESULT",SqlDbType.Int)

I know the Output parameter is returned after the SqlDataReader is closed. From what I think I know, the Using statement will call .Dispose on the SqlDataReader, so will that basically wipe out the Output parameter? If so, what is the best method to call a SqlDataReader that also contains Output parameters that closes and disposes everything correctly? Let me add that based on what I've read you only have access to the Output parameter using a SqlDataReader after you call .Close on the SqlDataReader.
When I check the value of nAmount it stil contains the original value -1 the output value didn't return from the stored procedure although the number of records updated is 0 or more. The procedure was checked, it works and there are records updated and the value of @Amount is SET to a value 0 or more. I just don't get the values back. eventough the parameter @Amount is defined as OUTPUT. I also tried with outParam.Direction = Data.ParameterDirection.InputOutput instead of outParam.Direction = Data.ParameterDirection.Output . Same result. How do I get the value back from the stored procedure?
How would I use a value from an output parameter from a stored procedure in a vb 2005 application. I would like to capture a run date from the procedure and show it on several forms in the app.
I'm in the process of switching my application from MSSQL to MYSQL. When I was using MSSQL, I retrieved the last auto increment value via
Private Sub dsImpoundInformation_Inserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles dsImpoundInformation.Inserted _impoundId = e.Command.Parameters("impoundId").Value End Sub
[Code]...
ultimately, I'm just trying to get the last auto increment value but there are other sections of my code in other applications that I plan on switching to MYSQL that depend on output parameters. I have't yet explored using stored procedures but at this time I would like to get this to work in a similar fashion to how I had it with MSSQL.
The mSSQL server I have a stored procedure. That does not have an output parameter.When I run it in SQL Management Studio so the procedure will output 1 cell.
My application uses a third party API. This API uses a few functions that returns a value by reference as one of the function parameters. Problem is according to their documentation, the value I am trying to get out of this function is a string pointer.
So if that made no sense, heres an example of the syntax of the function as shown in their documentation: long ExampleFunction(long ID, long PropNum, char* name, long MaxStringLength) Input Parameters: ID, PropNum Output Parameters: name, MaxStringLength
Thats pretty much all the info I've got. Obviously they are not using VB.Net, looks like C to me. I want to get the name output parameter and work with it, but once I get this value, I cant change anything. I know this is because its a pointer (reference type?) but I am still at a loss as to what to do.
However, I now have the problem when I loop the code string I get the following error: "Parameter '?PassVar' has already been defined.". I never had this problem before I upgraded.
I am very new to programming so sorry for the simple question, but I am at a lose. What the program needs to do is take a user defined starting and ending range, and then build a table based on that range. Inside the table each record will need to have two check boxes.
So for example the user enters in a starting of ABC01 and ending ABC03 and clicks the button the table is populated like this;
I have a User defined table type(UDTT) in Sql 2008 I am writing VB Code to send data to Stored procedure that uses it as a parameter I have found that the datatable i build in VB has have columns in same order as udtt when passing it to SQl from VB Currently I have this roughly
In SQL Server Create type table my_table Field1 varchar(10) Field2 varchar(10)
I am looking for the best way to edit and update the value of a database column that is defined as data type TEXT. You can't use a replace command in SQL and if I read in the value, update the data and update the record, the changes are not applied.
I've create a new VS 2008 Window Form Project using VB. I added an oleDbDataAdapter to the first and only form, set it to a table in my Access 2007 Database (there is only one table, PK field autonum of course and two Memo fields). The Database is in the Project's folder. A standard oleDb Connection object was created, as I expected, then I select the DataAdapter and choose 'Generate Dataset' which produces a standard DataSet called 'DataSet1.xsd'. Now when I build the project I get an error 'Error 1 Type 'FontTest.DataSet1' is not defined.' I do have a reference in my new Project to System.Data.So what the @#%$@ is going on? Why isn't the Dataset create by the DataAdapter being recongized? I can get into the DataSet Designer. The DataTable create is perfect, three columns defined correctly as I expected.
SELECT * FROM tbl_Muffins WHERE OvenLoadId IN ( SELECT OvenLoadId
[code]....
The idea of the query is that I want to specify an OrderId, and I want all Oven Loads that have items from that order in them, as well as ALL OTHER ITEMS in those loads, even though they could be from other orders.The query works as expected, but I'm not able to use it for my Crystal Report I've written it for.I have put this query into a User Defined Function, however I'm unable to use a call to that function as a table source in my Crystal Report. I am using Visual Studio 2003 (I know it is old, the client refuses to upgrade).
Dim tbl as String = Request.QueryString("tb") 'tb value = User Dim sql As String = "Select * From @table Where @Col = @ColVal" Dim para As New SqlParameter
[Code]....
what should I do to run the sql with given table name as parameter and avoid the sql injection.
I want to paste table name as function parameter and function need to return DataSet, this is the my code for that:
Public Function GetTTabele(ByVal tableName As String) As DataSet Dim DAT As SqlDataAdapter = New SqlDataAdapter("SELECT * FROM tableName", nwindConn) Dim DAT As DataSet = New DataSet() DAT.MissingSchemaAction = MissingSchemaAction.AddWithKey DAT.Fill(DAT, tableName) GetTTabele = DAT End Function
Now when I execute this code I'm getting next error: System.Data.SqlClient.SqlException: Invalid object name 'tableName'.
I am trying to execute a stored procedure which has table valued parameters along with other parameters. The only parameters I need to pass values for are latitude/longitude range and dates. For the others, I need to pass null. After a lot of searching and a lot of trial and error, I came up with the following:
Dim empty As IEnumerable = Enumerable.Empty(Of SqlDataRecord)()
I then pass empty for the table valued parameters. This works for the first two tvp's, but on the third one, I get this error:
There are no records in the SqlDataRecord enumeration. Tho send a table-valued parameter with no rows, use a null referece for the value instead.
how to make this work? I do not have control over the database or the stored procedure, so I can't change that. The code that calls the stored procedure is:
