Executes the parameterised prepared SQL statement represented by Cursor, previously prepared by session_sql_prepare/4 or session_sql_prepare_query/5. The statement is executed once for each tuple in TupleList, with the parameter values supplied by that tuple. The tuples are executed in the order they are in TupleList, and any results produced are discarded when the next tuple is executed.
Each tuple is a structure whose name and arity match the parameter template when Cursor was prepared, and the arguments give the values for the parameters for this execution, and must be compatible with the type specified by the template, except that an argument can be an uninstantiated variable, to denote a NULL value for the corresponding parameter.
