My Answer:
To left join two tables and get the latest row in the second table based on a date column, you can use a subquery in the WHERE clause. Here's an example:

php

SELECT t1.*, t2.*

FROM table1 t1

LEFT JOIN table2 t2 ON t1.id = t2.table1_id

WHERE t2.date = (SELECT MAX(date) FROM table2 WHERE table1_id = t1.id)

In this query:
- `table1` and `table2` are the names of your tables
- `id` is the primary key in `table1` and `table1_id` is the foreign key in `table2` that references `id` in `table1`
- `date` is the date column in `table2` that you want to use to get the latest row
- The subquery `(SELECT MAX(date) FROM table2 WHERE table1_id = t1.id)` gets the maximum date value for each `table1_id` in `table2`
- The WHERE clause filters the results to only include rows where the date in `table2` is the latest for each `table1_id`

This query will return all rows from `table1` and the corresponding latest row from `table2` based on the date column.
