If you have access to the SQL code which created the table the primary key can be seen easily. The primary key may be specified in one of two ways:
CREATE TABLE cia (name PRIMARY KEY, population INTEGER)or, where the primary key is composite:
CREATE TABLE casting(movieid INTEGER,
actorid INTEGER,
PRIMARY KEY (movieid, actorid)
)
If this is not possible then implementation specific commands may work. | ||
