'Usage
Dim command As OracleCommand 

OracleCommandBuilder.DeriveParameters(command)

Parameters

command
Type: System.Data.OracleClient.OracleCommand

The OracleCommand referencing the stored procedure from which the parameter information is to be derived. The derived parameters are added to the Parameters collection of the OracleCommand.

ExceptionCondition
InvalidOperationException

The command text is not a valid stored procedure name, or the CommandType specified was not StoredProcedure.

DeriveParameters overwrites any existing parameter information for the OracleCommand.

DeriveParameters requires an extra call to the database to obtain the information. If the parameter information is known in advance, it is more efficient to populate the parameters collection by setting the information explicitly.

You can only use DeriveParameters with stored procedures. You cannot use DeriveParameters to populate the OracleParameterCollection with arbitrary Transact-SQL statements, such as a parameterized SELECT statement.
