What is the second word that starts with "IN" in SQL?

In SQL (Structured Query Language), the second word that commonly starts with "IN" is "INNER".

The most common SQL construct where you'll find words starting with "IN" is in JOIN clauses.

Let's break it down:

1. JOIN Clause:

- SQL uses `JOIN` clauses to combine rows from two or more tables based on a related column between them. There are different types of `JOIN`s, including `INNER JOIN`, `LEFT JOIN`, `RIGHT JOIN`, and `FULL OUTER JOIN`.

2. INNER JOIN:

- The `INNER JOIN` returns records that have matching values in both tables. It only includes rows where the join condition is met.

3. Example:

If you have two tables, 'Customers' and 'Orders', you can join them with:

SELECT
FROM Customers
INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID;

In this SQL query, "INNER" is the second word that starts with "IN". The word "IN" itself is also frequently used in SQL (e.g., with `WHERE` clause), but the second word starting with "IN" in context of joins is typically "INNER".

Therefore, the second word that starts with "IN" in the context of SQL join clauses, such as the example, is "INNER".
