This tutorial will show you how we can use Codeigniter’s Query Builder Class to build join queries for fetching data from multiple tables.
The SQL Join clause is used to combine records together from two or more tables in a database. A JOIN locates related column values in two or more tables. This will display all the records that have matched. Join and Inner Join are functionally equivalent, but INNER JOIN can be a bit clearer to read, especially if the query has other join types (i.e. LEFT or RIGHT or CROSS) included in it. Here we will see Join or Inner Join example.
We will use Codeigniter’s $this->db->join() that permits you to write the JOIN portion of your query.
