The main advantage of a join is that it executes faster. The performance increase might not be noticeable by the end user. However, because the columns are specifically named and indexed and optimized by the database engine, the retrieval time almost always will be faster than that of a subquery.

Advantages of join operation is faster. Representation rise might not be  remarkable by the end user. cause the columns are specifically named and indexed and optimized by the database engine, the retrieval time almost always will be faster than that of a subquery. There are also inner and outer joins, left and right joins, full joins and cross joins. A disadvantage of using joins is that they are not as easy to read as subqueries. Another disadvantage is that it can be confusing as to which join is the appropriate type of join to use to yield the correct desired result set.

Re: Advantages of join operation

Using JOINS, we can fetch exactly the data we want from any number of tables with just one query, using any search parameter we chose to filter the results.

There is another advantage to the use of joins. By using joins instead of multiple queries, we maximize the placement of the calculation burden on the database. This means we can make better use of the database's abilities to search through, filter, sort, etc.

The advantage of join operation The retrieval time of the query using joins almost always will be faster than that of a  sub query. And  advantage of a join includes that it executes faster.By using joins, you can maximize the calculation burden on the database , instead of multiple queries using one join query. This means you can make better use of the database’s abilities to search through, filter, sort, etc.

The main advantages of join is that it is executes faster. The performance might not be noticeable by the end user. However, beacause the columns are specially name and indexed and optimized by the database engine, the retrival time almost always will be faster than that of a subquery. There are also inner joins nad outer joins, full joins, cross joins, left joins and  right joins.

The join operation helps you to combine data from two or more tables, thereby reducing the need to repeat columns and columns of data in the same table. It creates a logical link between two or more tables. So, you can select a set of tables which are related by foreign keys, you can easily enter the equi join condition in the WHERE clause, and get all the details of a particular record.

Re: Advantages of join operation

by Ashrak Shohas -
Join is a special form of cross product of two tables. In Cartesian product we join a tuple of one table with the tuples of the second table. But in join there is a special requirement of relationship between tuples. For example if there is a relation STUDENT and a relation BOOK then it may be required to know that how many books have been issued to any particular student. Now in this case the primary key of STUDENT that is stId is a foreign key in BOOK table through which the join can be made.

Join is a special kind of operation. Most join can be rewritten as sub queries. A join defines two or more tables by a related column. Tables usually are joined on primary and foreign keys. For example, an employee table might have a primary key of and employee id column, while a time sheet table also has an employee id column that is a foreign key to the employee table.
The main advantage of a join is that it executes faster. There are also inner and outer joins, left and right joins, full joins and cross joins. However, because the columns are specifically named and indexed and optimized by the database engine, the retrieval time almost always will be fast than that of a sub query.
