Load Sales Records into a Partitioned Table Automatically

Inserting Data into a Partitioned Table

Write a PostgreSQL query to insert sales data into the Sales partitioned 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 ('2023-05-15', 500.00);

Explanation:

• Purpose of the Query:
• Inserts data into the parent table, automatically routing it to the correct partition.
• Real-World Application:
• Simplifies data entry without manually specifying partitions.

Notes:

• Ensure partitions exist for the date range being inserted.

• Write a PostgreSQL query to insert multiple rows into a partitioned table and ensure each row is routed to the correct partition based on the partitioning key.
• Write a PostgreSQL query to insert a record into a range-partitioned table for sensor data, triggering the appropriate partition based on a timestamp.
• Write a PostgreSQL query to insert order data into a list-partitioned table where the order's region value determines the target partition.
• Write a PostgreSQL query to insert customer data into a hash-partitioned table and verify that records are distributed evenly across partitions.
