All parameters in the collection are treated as positional parameters and must be added to the collection in the same order
as the corresponding question mark placeholders in the ULCommand.CommandText value. For example, the first parameter in the
collection corresponds to the first question mark in the SQL statement, the second parameter in the collection corresponds
to the second question mark in the SQL statement, and so on. There must be at least as many question marks in the ULCommand.CommandText
value as there are parameters in the collection. Nulls are substituted for missing parameters.
