Which type of join fetches all records from the left table along with matched records from the right table?

The left join is designed to retrieve all records from the left table, regardless of whether there is a match in the right table. When using a left join, the resulting dataset will include all entries from the left table, and for those entries that do not have corresponding matches in the right table, the output will display null values for the columns coming from the right table. This is particularly useful when you want to ensure that all data from the primary table (the left table) is represented in the final result, even if there are no matching entries in the secondary table (the right table).

In contrast, other types of joins, such as the right join, inner join, and full join, do not exhibit the same behavior. A right join focuses on retrieving all records from the right table and only matched records from the left table. An inner join retrieves only those records that have matching values in both tables, discarding any non-matching entries. A full join combines results from both left and right joins, displaying all records from both tables while inserting nulls where there are no matches. Thus, the left join specifically addresses the requirement to pull all records from the left and selectively from the right based on matches.
