-----------------------------------------------------------------------------------------------------------------------------------
A chosen set of columns which uniquely identify a table.  In the relational model (as in set theory) the columns of a primary key 
are not ordered. In SQLI they must be, in order to map to the quasi- hierarchical model of M globals.  
 
FileMan subfiles (multiples) have a primary key element for each parent plus one for the subfile. Each contains a pointer to its
primary key table element (SQLI_TABLE-ELEMENT), a sequence and a column in the local base 
 table (SQL_COLUMN).
