SQL Right Join Example | Right Outer Join In SQL

SQL Right join returns all records from the right table (table2), and the matched records from the left table (table1). The result is NULL from the left side when there is no match. RIGHT JOIN performs a join starting with the second (right-most) table and then any matching first (left-most) table records.

RIGHT JOIN and RIGHT OUTER JOIN are the same.

SQL Right Join Tutorial With Example

SQL RIGHT JOIN keyword returns all the records from the right table (table2), and the matched records from a left table (table1). The result is NULL from the left side when there is no match. In some databases, the RIGHT JOIN is called RIGHT OUTER JOIN. The RIGHT JOIN clause allows us to  query data from the multiple tables.

Introduction to Structured Query Language SQL pdf

SQL stands for Structured Query Language. SQL is a scripting language expected to store, control, and inquiry information put away in social databases. The main manifestation of SQL showed up in 1974, when a gathering in IBM built up the principal model of a social database. The primary business social database was discharged by Relational Software later turning out to be Oracle.

Models for SQL exist. In any case, the SQL that can be utilized on every last one of the major RDBMS today is in various flavors. This is because of two reasons:

1. The SQL order standard is genuinely intricate, and it isn’t handy to actualize the whole standard.

2. Every database seller needs an approach to separate its item from others.

Right now, contrasts are noted where fitting.

Your Ultimate Guide to SQL Join: CROSS JOIN

CROSS JOIN is in the spotlight. This article finishes our small series of SQL JOIN-related publications.

SQL Server CROSS JOIN is the simplest of all joins. It implements a combination of 2 tables without a join condition. If you have 5 rows in one table and 3 rows in another, you get 15 combinations. Another definition is a Cartesian Product.

Now, why would you want to combine tables without a join condition? Hang on a bit because we are getting there. First, let’s refer to the syntax.

#sql server #cross join #inner join #outer join #sql join #sql

Your Ultimate Guide to SQL Joins: OUTER JOIN

Outer join is at the center stage today. And this is part 2 of your ultimate guide to SQL joins. If you missed part 1, here’s the link.

By the looks of it, outer is the opposite of inner. However, if you consider the outer join this way, you’ll be confused. To top that, you don’t have to include the word outer in your syntax explicitly. It’s optional!

But before we dive in, let’s discuss nulls concerning outer joins.

Nulls and OUTER JOIN

When you join 2 tables, one of the values from either table can be null. For INNER JOINs, records with nulls won’t match, and they will be discarded and won’t appear in the result set. If you want to get the records that don’t match, your only option is OUTER JOIN.

Going back to antonyms, isn’t that the opposite of INNER JOINs? Not entirely, as you will see in the next section.

SQL Outer Join Example | Left, Right, and Full Outer Join

SQL Outer join returns all the contents of both the tables are combined either they are matched or not. In the outer join, unmatched rows in one or both tables can be returned. The SQL OUTER JOIN returns all the rows from both the participating tables which satisfy a join condition along with rows that do not meet the join criteria.

If you are new to this blog in SQL, then I have previously described  Cross Join,  Inner Join, and  Left Join. In the SQL outer JOIN, all the content of both tables is integrated either they are matched or not.

When performing the  inner join, rows from either table that are unmatched in the other table are not returned in the final result set. In the outer join, the unmatched rows in one or both tables can be returned.

What is the use of SQL OUTER JOIN

In SQL Outer Join all the contents of both the tables are combined either they are matched or not.

In the outer join, unmatched rows in one or both tables can be returned.
