Container objects such as C++ arrays, STL vectors, etc. map to multiple consecutive rows of the database table that represents the object's type. The row count stored in the "pointer" to the data (see the "SQL table names" section above) will contain the number of elements that the original container had (if the container was empty then the SQL NULL value will be written as the value of the "pointer" instead of a "pointer" such as "4;0;5;3").
