Examples

The following example creates an OleDbParameter and sets some of its properties.

Public Sub CreateOleDbParameter()  
    Dim parameter As New OleDbParameter("Description", OleDbType.VarChar, 88)  
    parameter.SourceColumn = "Description"  
End Sub 'CreateOleDbParameter  

public void CreateOleDbParameter()   
 {  
    OleDbParameter parameter = new OleDbParameter("Description", OleDbType.VarChar, 88);  
    parameter.SourceColumn = "Description";  
 }

Remarks

When SourceColumn is set to anything other than an empty string, the value of the parameter is retrieved from the column with the SourceColumn name. If Direction is set to Input, the value is taken from the DataSet. If Direction is set to Output, the value is taken from the data source. A Direction of InputOutput is a combination of both.
