Examples

The following example creates a 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  
public void CreateOracleDbParameter()   
{  
   OracleParameter parameter = new OracleParameter();  
   parameter.ParameterName = "pDName";  
   parameter.DbType = DbType.String;  
   parameter.Value = "ENGINEERING";  
   parameter.SourceColumn = "DName";  
}  

Remarks

If the ParameterDirection is output, and execution of the associated OracleCommand does not return a value, the OracleParameter contains a null value.

Output, InputOut, and ReturnValue parameters returned by calling ExecuteReader cannot be accessed until you call Close on the OracleDataReader.
