Question

When writing an outer join, the keyword OUTER must be included. True/False

Answer 1

False, the keyword OUTER is not required when writing an outer join.

Step-by-step explanation:

False, the keyword OUTER is not required when writing an outer join. In most SQL databases, including MySQL, Oracle, and SQL Server, the OUTER keyword is optional.

When writing an outer join, the syntax typically involves using the keywords LEFT JOIN or RIGHT JOIN, along with the ON clause to specify the join condition. The OUTER keyword is used in some SQL databases like PostgreSQL, but it is not universally required.

For example, in MySQL, you can write an outer join using the following syntax:

SELECT * FROM table1 LEFT JOIN table2 ON table1.id = table2.id;
