My problem is this (apologies if this is a little long ... hang in there):I can define a function in VB.NET with optional parameters that wraps a SQL procedure:
Sub Test(OptionalByVal Arg1 As Integer _
Optional ByVal Arg2 As Integer _
Optional ByVal Arg3 As Integer

I am trying to speed up the development phase by using codesmith for generating the business class DAL and info class for the tables of my project. There are about 50 tables with relationships parent child many to many and for retrieving data I have to code several inner joins in stored procedures. I have to combine fields from many tables and this makes working with the info class difficult. Is there anyway to generate info class from stored procedures or to be more exact is there a way to parse the result set of the stored procedure and to generate the info class with properties for every column in that result set.
View 3 RepliesI have a problem during defining a Sub routine in VB.Net. I am defining a sub routine which is as under
Private Sub ActivateControls(rdbutton as RadioButton, Optional txt as Textbox, Optional txt2 as Textbox)
End sub
When I call this sub routine It gives me the Error that Each Optional Parameter must specify a default value. So, Here I can't understand that what can be the default value of a textbox. What default value I can use here to remove this error.
I think this is a pretty basic question, but I just want to clarify. If I have a variable with a null value, and pass it as a parameter that is optional, will the parameter get the null value, or the default value?
dim str As String = "foo"
dim obj As Object

I have a stored procedure to update a table, but needs a couple of values from another table.
the first two selects get the value from the table and then are used in the update statement.
The select statments:
Select @iStatusDropDownValueID = iDropDownValueID
From DropDownValue
Inner Join DropDownValueType On DropDownValue.iDropDownValueTypeID =
[Code].....
First, the values that are retrieved by the first two select statements are always the same. So they could be passed in by the code itself. I don't know that this will speed things up at all, just make the entire stored procedure better and easier to read.
Second, if the "Value Name" should change this store procedure will break (which is possible, but not often).
I am looking for any insight into the Best Practices for this situation.

Hey Guys, I have a problem with something that should be pretty simple. I have stored procedure that I pass 1 input parameter and expect 2 output parameters back. Instead I get this error:
"Procedure or function 'MESSP_Get_PLCKitColour' expects parameter '@KitNo', which was not supplied."
I would appreciate some help with this.

Everyone here has always been such great help, either directly or indirectly. And it is with grand hope that this, yet again, rings true.For clarification sakes, the Stored Procedure is running under FireBird and the VB is of the .NET variety

in my SQL 2005 database I have defined this stored procedure:
CREATE PROCEDURE [dbo].[CheckOrders] (
@PK_Customer uniqueidentifier,
@Amount bigint OUTPUT)
[code]....
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?
I am using LLBLGEN Pro to generate a data layer...some of my stored procs have parameter name as "date"...so this is cauing a problem when I compile in VS2010...I have to go through the class and change the function parameters "date" to "[date]".
Is there a way to inject these changes in LLBLGEN Pro during code generation?
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.
View 2 RepliesI have a two part question really. The first part is about a stored procedure I have almost perfectly correct. This stored procedure below currently returns all the rows found in a table. I need to get only one value based on a unique value field in the table. The unique field is called descriptor. So I need to know what I do to modify the current SP to make it look for a unique descriptor value in that field and then hand back the resulting data the stored procedures generates. I am also looking for a code sample in VB.NET that would initiate the call with the correct descriptor parameter handed into the stored procedure and get back the result. My understanding is typically stored procedures generally return an integer to signify success or failure of it executing. Again I need to have the SP perform a query and then act on the data (as it does now) and then hand back the given result to VB. Apparently the VB call is subtlety different when you need a value back.

I create a dictionary in a function which I pass to the function executing the sproc.
Dim PParamDict As New Dictionary(Of String, String)
PParamDict.Add("sname", name)
PParamDict.Add("sdescription", description)
PParamDict.Add("sLoggedInID", LoggedInID)
PParamDict.Add("sCompanyID", CompanyID)
The dictionary gets passed to the function PParamDict -> ParameterDict
Dim dbComm As New MySqlCommand(ProcedureName, PConnection)
Dim pair As KeyValuePair(Of String, String)
For Each pair In ParameterDict
dbComm.Parameters.AddWithValue(pair.Key, pair.Value)
[Code] .....
This works as long as the PParamDict.Add statements are in that order. If they're in a different order they get passed as they come in. This is the most ridiculous thing I've ever seen, I'm passing the keys to the MySqlCommand which are defined letter for letter in the sproc.

I have one problem when passing value to parameters for Crystal Report Viewer. The parameters are from Stored Procedure which I have defined.
My aim is to accept values from user and display it accordingly. I try to write code as below in Button View Click Event:
[code=language]
Dim rptdoc As New ReportDocument
rptdoc.Load(Application.StartupPath & "ReportsSummaryAdsRecordBetweenDate.rpt")
'@startdate is parameter in stored procedure
[Code].....
But the problem is that Crystal Report Viewer does not accept my passed values and prompt me to input values for @startdate and @enddate in its dialog box.
i'm trying to execute a SQL stored procedure with a parameter that needs the SQL datetime format as:
Dim str_runproc As String
str_runproc = "exec UP_stopactivity @Activity='" & DGV_currentactivities.CurrentRow.Cells(0).Value & "' ,@Client='" & DGV_currentactivities.CurrentRow.Cells(2).Value & "',@starttime='" &
DGV_currentactivities.CurrentRow.Cells(3).Value & "'"
the DGV_currentactivities.CurrentRow.Cells(3).value is a datetime value that is put into a Datagridview via another stored procedure. When I run it in sql, it lists as a correct SQL datetime: 2011-04-27 05:54:51.003, in the datagridview it lists as: 27/04/2011 5:54:51

I have three ways of adding parameters to my query commented out above. The all seem to return 1781 records (which is all of the records) and will not filter out to what the UserName variable equals which should reduce it to 32 rows.
I use a Console.WriteLine to show that the UserName is indeed my username. But it seems to not be getting passed to the query properly. I tested the Stored Procedure before even starting in on the program, so I know it functions properly. I just don't know what I'm missing from a VB.NET perspective to get the same results into my DataTable.
