A ULParameterCollection object holding the parameters of the SQL statement. The default value is the empty collection.
Use question marks in ULCommand.CommandText property value to indicate parameters. The parameters in the collection are specified
in the same order as the question mark placeholders. 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 property as there
are parameters in this collection.
This is the strongly-typed version of System.Data.IDbCommand.Parameters and System.Data.Common.DbCommand.Parameters.
