Add Sales Data That Routes to the Correct Partition

Inserting Data into a Partitioned Table

Write a PostgreSQL query to insert a new record into the Sales table.

Solution:

-- Insert a new row into the Sales table (which is partitioned by sale_date)
INSERT INTO Sales (sale_date, amount)
-- Specify the sale_date and amount values for the new row
VALUES ('2024-06-15', 750.00);

Explanation:

• Purpose of the Query:
• Inserts data into the parent table, which automatically routes it to the correct partition.
• Real-World Application:
• Prevents users from needing to specify partitions manually.

Notes:

• Ensure that a partition exists for the inserted date range.
