Is there a way to update composite keys on save?
Moved to the general development discussion board. The upsert method only supports a single field so you'll need to create a field to represent your key and you can use a workflow field update or apex trigger to set the key on save whenever an element of the composite key is updated.

Can candidate keys be composite?
A Composite key is a Candidate key or Primary key that consists of more than one attribute. Sometimes it is possible that no single attribute will have the property to uniquely identify tuples in a table. In such cases, we can use a group of attributes to guarantee uniqueness.
Is composite key an object?
In database design, a composite key is a candidate key that consists of two or more attributes (table columns) that together uniquely identify an entity occurrence (table row). A compound key is a composite key for which each attribute that makes up the key is a foreign key in its own right.
How do you create a composite primary key in a table?
We will use the below query to create a Composite Key. Query: CREATE TABLE COMPO ( EMP_ID INT, DEPT_ID INT, EMPNAME VARCHAR(25), GENDER VARCHAR(6), SALARY INT --> //This statement will create a //composite Primary Key from PRIMARY KEY (EMP_ID,DEPT_ID) with the help of Column EMP_ID and DEPT_ID );

While a primary key and a composite key might do the same things, the primary key will consist of one column, where the composite key will consist of two or more columns.
Is candidate key and primary key same?
The difference here is that a primary key acts as a minimal super key. Thus, a relation can only have one primary key. On the other hand, multiple candidate keys (two or more) can take place in any relationship. The attributes in a candidate key may contain a NULL value that opposes the primary key in it.
