Refer to article Using Parameters in dotConnect for Oracle to obtain detailed information on the matter together with some advanced examples.

Example

The following example creates multiple instances of OracleParameter through the OracleParameterCollection within the OracleDataAdapter. These parameters are used to select data from Oracle and place the data in the System.Data.DataSet. This example assumes that a System.Data.DataSet and a OracleDataAdapter have already been created with the appropriate schema, commands, and connection.

csharp

public void AddOracleParameters()
{
  // ...
  // create myDataSet and myDataAdapter
  // ...
  myDataAdapter.SelectCommand.Parameters.Add("DName", OracleDbType.VarChar, 15).Value = "DEVELOPMENT";
  myDataAdapter.SelectCommand.Parameters.Add("DeptNo", OracleDbType.Integer).Value = 50;
  myDataAdapter.Fill(myDataSet);
}

Visual Basic

Public Sub AddOracleParameters()
  ' ...
  ' create myDataSet and myDataAdapter
  ' ...
  myDataAdapter.SelectCommand.Parameters.Add("DName", OracleDbType.VarChar, 15).Value = "DEVELOPMENT"
  myDataAdapter.SelectCommand.Parameters.Add("DeptNo", OracleDbType.Integer).Value = 50
  myDataAdapter.Fill(myDataSet)
End Sub
