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_descr
FROM customer c, OUTER cust_calls u
WHERE c.customer_num = u.customer_num
The OUTER before the cust_calls table makes it the
subservient 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.
