Outer Joins in Where Clause

What’s the syntax for outer joins in the where clause in Informix?

The syntax is:

SELECT c.customer_num, c.lname, c.company,c.phone, u.call_dtime, u.call_descrFROM customer c, OUTER cust_calls uWHERE c.customer_num = u.customer_num

The OUTER before the cust_calls table makes it thesubservient table. An outer join causes the query to return information on all rows of the dominant table and only those of the subservient table that match the join.
