SiebelParameter class in the Siebel adapter

The Data Provider for Siebel provides a DbParameter implementation to enable an ADO.NET client to specify parameters for a particular command. Using an instance of the System.Data.Common.DbCommand class of the Data Provider for Siebel, a client program can obtain an instance of the System.Data.Common.DbParameter class.

//In this example, command is an instance of DbCommand  
DbParameter param = command.CreateParameter();  

Alternatively, the following approach can be used:

//Here command is an instance of SiebelCommand  
SiebelParameter param = (SiebelParameter) command.CreateParameter();                  
param.ParameterName = "@Time";  

The SiebelParameter class inherits from DbParameter. It exists in the namespace Microsoft.Data.SiebelClient.
