Sql subjoined email
You're looking for a SQL query that joins two tables based on an email column. Here's an example:
Let's say you have two tables:
Table 1: Users
| id | name | |
|---|---|---|
| 1 | John | [email protected] |
| 2 | Jane | [email protected] |
| 3 | Bob | [email protected] |
Table 2: Orders
| id | user_id | order_date |
|---|---|---|
| 1 | 1 | 2022-01-01 |
| 2 | 1 | 2022-01-15 |
| 3 | 2 | 2022-02-01 |
| 4 | 3 | 2022-03-01 |
You want to join these two tables based on the email column in the Users table. Here's the SQL query:
SELECT u.name, u.email, o.order_date
FROM Users u
JOIN Orders o ON u.email = o.user_id;This query will return the following result:
| name | order_date | |
|---|---|---|
| John | [email protected] | 2022-01-01 |
| John | [email protected] | 2022-01-15 |
| Jane | [email protected] | 2022-02-01 |
| Bob | [email protected] | 2022-03-01 |
Note that the JOIN clause is used to combine rows from two or more tables based on a related column. In this case, we're joining the Users table with the Orders table based on the email column.
Also, the ON clause specifies the condition for joining the tables. In this case, we're matching the email column in the Users table with the user_id column in the Orders table.
