What is an inner join in SQL?
An example of an AI chatbot conversation about inner joins in SQL.
Can you explain what an inner join is in SQL?
Sure! An inner join is a type of join that returns rows from two or more tables where there is a match between the columns being joined.
How does it differ from other types of joins?
Unlike outer joins, which return all rows from one table and matched rows from another, inner joins only return rows with matching values in both tables.
Can you give me an example of an inner join?
Of course! If you have a 'Customers' table and an 'Orders' table, an inner join would return only the customers who have placed orders.
What SQL syntax is used for an inner join?
The syntax is: SELECT columns FROM table1 INNER JOIN table2 ON table1.column = table2.column; This retrieves the matching rows.
