PROBLEM TO BE SOLVED: To provide a base table primary key assigning system for automatically generating the table primary key of a relational database through the use of a program without the manual operation of a database manager when the table primary key is generated, saving labor, and optimizing relation. SOLUTION: The primary key of a table including hierarchical contents such as the department names of an enterprise, the addresses of individuals, and product classification information concerning the attributes of relation is generated in the relational database. In this case, the primary key is generated through the use of a means for referring to a field name (a string name) in an SQL sentence in the order corresponding to the attributes of the table (the string) by using a program, thereby generating a record set object.
