Advanced Relational Database /* Inner Join between two tables */

The JOIN keyword is used in an SQL statement to query data from two or more tables, based on a relationship between certain columns in these tables.Tables in a database are often related to each other with keys.A primary key is a column (or a combination of columns) with a unique value for each row. Each primary key value must be unique within the table. The purpose is to bind data together, across tables, without repeating all of the data in every table.
