An SQL join clause - corresponding to a join operation in relational algebra - combines columns from one or more tables in a relational database. It creates a set that can be saved as a table or used as it is. A JOIN is a means for combining columns from one or more tables by using values common to each
Different Types of SQL JOIN OPERATION:
(INNER) JOIN: Returns records that have matching values in both tables. LEFT (OUTER) JOIN: Returns all records from the left table, and the matched records from the right table. RIGHT (OUTER) JOIN: Returns all records from the right table, and the matched records from the left table.
(INNER) JOIN: Returns records that have matching values in both tables. LEFT (OUTER) JOIN: Returns all records from the left table, and the matched records from the right table. RIGHT (OUTER) JOIN: Returns all records from the right table, and the matched records from the left table.
A SQL Join is a special form of generating a meaningful data by combining multiple tables relate to each other using a “Key”. Typically, relational tables must be designed with a unique column and this column is used to create relationships with one or more other tables. When you need a result-set that includes related rows from multiple tables, you’ll need to use SQL join on this column
The various SQL join types are as follows
SQL inner join
Equi join
Non-equi join (Theta join)
SQL outer join
SQL left join or left outer join
SQL right join or right outer join
SQL full join or full outer join
SQL cross join
SQL self join

JOINS in SQL are commands which are used to combine rows from two or more tables, based on a related column between those tables. There are predominantly used when a user is trying to extract data from tables which have one-to-many or many-to-many relationships between them.
There are mainly four types of joins that you need to understand. They are:
1: INNER JOIN
2: FULL JOIN
3: LEFT JOIN
4: RIGHT JOIN

SQL Join is used to fetch data from two or more tables, which is joined to appear as single set of data. It is used for combining column from two or more tables by using values common to both tables.
JOIN Keyword is used in SQL queries for joining two or more tables. Minimum required condition for joining table, is (n-1) where n, is number of tables. A table can also join to itself, which is known as, Self Join.

It creates a set that can be saved as a table or used as it is. A JOIN is a means for combining columns from one (self-join) or more tables by using values common to each. ANSI-standard SQL specifies five types of JOIN: INNER, LEFT OUTER, RIGHT OUTER, FULL OUTER and CROSS. As a special case, a table (base table, view, or joined table) can JOIN to itself in a self-Join

JOIN returns all rows of tables where the key record of one table is equal to the key records of another table. INNER JOIN will pick all rows from the two participating tables as long as there is a match between the columns. The SQL INNER JOIN is the same as the JOIN clause, which adds rows from two or more tables.
