Examples

The following example calls a Stored Procedure with three parameters using the ODBC managed provider.

public void CreateMyProc(OdbcConnection connection)
{
    OdbcCommand command = connection.CreateCommand();
    command.CommandText = "{ call MyProc(?,?,?) }";

    OdbcParameter param = new OdbcParameter();
    param.DbType = DbType.Int32;
    param.Value = 1;
    command.Parameters.Add(param);

    param = new OdbcParameter();
    param.DbType = DbType.Decimal;
    param.Value = 1;
    command.Parameters.Add(param);

    param = new OdbcParameter();
    param.DbType = DbType.Decimal;
    param.Value = 1;
    command.Parameters.Add(param);

    command.ExecuteNonQuery();
 }

Public Sub CreateMyProc(ByVal connection As OdbcConnection)

  Dim command As OdbcCommand = connection.CreateCommand()
  Command.CommandText = "{ call MyProc(?,?,?) }"

  Dim param As New OdbcParameter()
  param.DbType = DbType.Int32
  param.Value = 1
  command.Parameters.Add(param)

  param = New OdbcParameter()
  param.DbType = DbType.Decimal
  param.Value = 1
  command.Parameters.Add(param)

  param = New OdbcParameter()
  param.DbType = DbType.Decimal
  param.Value = 1
  command.Parameters.Add(param)

  command.ExecuteNonQuery()

End Sub

Remarks

The OdbcType and DbType are linked. Therefore, setting the DbType changes the OdbcType to a supporting OdbcType.

For a list of the supported data types, see the appropriate OdbcType member. For more information, see DataAdapter Parameters.

Note

Object is not supported by the Microsoft .NET Framework Data Provider for ODBC.
