Right outer join oracle

Overview of RIGHT OUTER JOIN in Oracle Suppose we have two tables T1 and T2, the following statement shows how to join these two tables using the RIGHT OUTER JOIN clause in Oracle: SELECT column_list FROM T1 RIGHT OUTER JOIN T2 ON join_predicate; In this statement, T1 and T2 are the left and right table respectively What is a right outer join in Oracle? A RIGHT OUTER JOIN performs an inner join of two tables (supposed table A which writes before the join keyword and table B which writes after the join keyword in the SQL statement) based on the condition specified after the ON keyword A RIGHT OUTER JOIN is one of the JOIN operationsthat allow you to specify a JOIN clause. It preserves the unmatched rows from the second (right) table, joining them with a NULL in the shape of the first (left) table. A LEFT OUTER JOIN B is equivalent t Oracle right Outer Join. Oracle Tips by Burleson Consulting Don Burleson . Starting with Oracle9i, the confusing outer join syntax using the (+) notation has been superseded by ISO 99 outer join syntax. As we know, there are three types of outer joins, right, right, and full outer join. The purpose of an outer join is to include non-matching rows, and the outer join returns these missing. The right join or right outer join is a reversed version of the left join. The right join makes a result set that contains all rows from the right table with the matching rows from the left table. If there is no match, the left side will have nulls. The following example use right join to join the left table to the right table

Oracle outer join operator (+) allows you to perform outer joins on two or more tables. Quick Example: -- Select all rows from cities table even if there is no matching row in counties table SELECT cities.name, countries.name FROM cities, countries WHERE cities.country_id = countries.id(+) As indicated in the official documentation, Oracle provides a special outer join operator (the + symbol) that is shorthand for performing OUTER JOINS. In practice, the + symbol is placed directly in the conditional statement and on the side of the optional table (the one which is allowed to contain empty or null values within the conditional)

The syntax for the Oracle RIGHT OUTER JOIN is: SELECT columns FROM table1 RIGHT [OUTER] JOIN table2 ON table1.column = table2.column; In some databases, the RIGHT OUTER JOIN keywords are replaced with RIGHT JOIN To write a query that performs an outer join of tables A and B and returns all rows from B (a right outer join), use the RIGHT [ OUTER] JOIN syntax in the FROM clause, or apply the outer join operator (+) to all columns of A in the join condition in the WHERE clause

Die Ergebnismenge eines OUTER JOINs umfasst die Schnittmengen zwischen A und B (dunkelblau) sowie die Restmenge (hellblau) von A (LEFT JOIN), B (RIGHT JOIN) oder A und B (FULL JOIN). Unterarten des OUTER JOINs I inherited an Oracle problem that involves a query structure that uses WHERE clauses as joins, rather than JOIN statements. SELECT * FROM po_distributions_all pod , pa_projects_all pap WHERE pod.project_id = pap.project_id(+) I understand this to be an outer join. The question is, which direction? Is this a (pod LEFT OUTER pap) or a (pod RIGHT OUTER pap) or (pap LEFT OUTER pod) or (pap RIGHT.
