OdbcCommandBuilder.DeriveParameters(OdbcCommand) Method

Definition

Namespace:

System.Data.Odbc

Assembly:

System.Data.Odbc.dll

Package:

System.Data.Odbc v8.0.0

Source:

OdbcCommandBuilder.cs

Retrieves parameter information from the stored procedure specified in the OdbcCommand and populates the Parameters collection of the specified OdbcCommand object.

public:
 static void DeriveParameters(System::Data::Odbc::OdbcCommand ^ command);

public static void DeriveParameters (System.Data.Odbc.OdbcCommand command);

static member DeriveParameters : System.Data.Odbc.OdbcCommand -> unit

Public Shared Sub DeriveParameters (command As OdbcCommand)

Parameters

command

OdbcCommand

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

Exceptions

InvalidOperationException

The underlying ODBC driver does not support returning stored procedure parameter information, or the command text is not a valid stored procedure name, or the CommandType specified was not CommandType.StoredProcedure.

Remarks

DeriveParameters overwrites any existing parameter information for the OdbcCommand.

DeriveParameters requires an additional call to the data source 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 OdbcParameterCollection with arbitrary Transact-SQL statements, such as a parameterized SELECT statement.
