Implements

The OracleType and DbType are linked. Therefore, setting the DbType changes the OracleType to a supporting OracleType.

The DbType, OracleType, and Size properties of a parameter can be inferred by setting Value. Therefore, you are not required to specify them. However, they are not exposed in OracleParameter property settings. For example, if the size of the parameter has been inferred, Size does not contain inferred value after statement execution. For String data types the default is AnsiString.

For a list of the supported data types, see the appropriate OracleType member. For more information, see DataAdapter Parameters (ADO.NET).

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

Public Sub CreateOracleDbParameter()
    Dim parameter As New OracleParameter()
    parameter.ParameterName = "pDName"
    parameter.DbType = DbType.String
    parameter.Value = "ENGINEERING"
    parameter.SourceColumn = "DName" 
End Sub
