passing parameters in selectcommand

While updating it passes parameters with updatecommand from dataset

How can it be done in selectcommand

passing parameters from dataset ?

try explaining yourself a litle bit more :-)

or post your code..

I mean before loading data I want to type in the textboxes
and use these as crietria from select command

Hi!

The dataadapter has a SelectCommand and the selectcommand has a parameter collection. So either add the parameter in design time or at run time and change the selectcommand to include a WHERE clause like "WHERE ContractID = @ContractID" where @ContractID is the name of the parameter.

Ofcourse you also have to pass a value to the parameter before trying to fill the dataset.

Code:

---

daContract.SelectCommand.Parameters("@ContractID").Value = txtContractID.Text

---

/Nisse

Yes I did so but it is not accepting the parameters

Did you define the parameter first?

Either by "dim":ing it, and adding it to the parameters collection? or selecting the data-adapter, check the selectcommand property and there create a parameter?

I made the changes in sql statement

select * from ......
where fld1=?....

and it autometically created the parameter but it gave error that it couldn't bind to the parameter?

How about something like this..

Code:

---

Public Sub SelectRecords()
        Dim MyConnection As New SqlClient.SqlConnection
        Dim myCommand As New SqlClient.SqlCommand


        myCommand.Parameters.Add(New SqlClient.SqlParameter("@CustomerID", TextBox1.Text))

        myCommand.CommandText = "SELECT * FROM MyTable WHERE CustomerID=@CustomerID"
        myCommand.Connection = MyConnection


    End Sub

---

I find that parameters work better using the SqlClient.SqlCommand instead of the OLEDB.OLEDBCommand

HTH

Thanks .
It works fine.but it gives error if I use master detail relationed form.
