Property Value

String

The name of the source column that will be used to set the value of this parameter. The default is an empty string ("").

Implements

SourceColumn

Examples

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

Public Sub CreateOdbcParameter()  
    Dim parameter As New OdbcParameter("Description", OdbcType.VarChar, 88)  
    parameter.SourceColumn = "Description"  
End Sub   

public void CreateOdbcParameter()   
 {  
    OdbcParameter parameter = new OdbcParameter("Description", OdbcType.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.
