List common data between two tables based on a join key in MySQL

Guide on writing a MySQL query to list common data between two tables based on a join key. This SQL command helps in finding records that are present in both tables.

SELECT t1.id, t1.date, t2.title
FROM table1 t1
INNER JOIN table2 t2 ON t1.id = t2.table1_id;

Detailed explanation:

1. INNER JOIN: Combines table1 with table2 based on the condition t1.id = t2.table1_id. INNER JOIN retrieves records that have matches in both tables, meaning only rows where id in table1 also exists in table2 are included.

2. SELECT t1.id, t1.date, t2.title: Chooses columns from both tables to display the common data. Here, id and date from table1 and title from table2 are selected.

MySQL Version:

This SQL query works on MySQL versions from 5.0 and above, as basic operations like INNER JOIN are supported in these versions.
