Normally four joins in Informatica
1) Normal join
2) Master join
3) Detail join
4) Full outer join

Answer / sanjaygupta1981

The Informatica supports the following types of joins:
• Normal
• Master Outer
• Detail Outer
• Full Outer

Normal join: discards all the rows of data from the master
and detail source that do not match, based on the condition.

SELECT * FROM employees, departments WHERE
employees.department_id = departments.department_id

Master outer join: discards all the unmatched rows from the
master source and keeps all the rows from the detail source
and the matching rows from the master source.

SELECT * FROM employees LEFT OUTER JOIN departments ON
(employees.department_id = departments.department_id)

Detail outer join: keeps all rows of data from the master
source and the matching rows from the detail source. It
discards the unmatched rows from the detail source.

SELECT * FROM employees RIGHT OUTER JOIN departments ON
(employees.department_id = departments.department_id)

Full outer join keeps all rows of data from both the master
and detail sources.

SELECT * FROM employees FULL OUTER JOIN departments ON
(employees.department_id = departments.department_id)
