CEILING in PostgreSQL - Examples & AI Generator

Mastering numeric rounding functions can be tricky—especially if you switch between SQL databases. In PostgreSQL, the CEILING function returns the smallest integer greater than or equal to your input. But remembering the exact PostgreSQL CEILING syntax across projects adds unnecessary friction. AI2sql lets you generate production-ready CEILING queries from plain English prompts—no coding required. Stop searching for syntax and start solving the business problem in seconds.

CEILING Syntax in PostgreSQL

CEILING(numeric_expression)

Note: In PostgreSQL, use CEILING (not CEIL as in some other databases).

CEILING Examples You Can Generate Instantly

1. Calculate Rounded-Up Order Amounts

SELECT order_id, amount, CEILING(amount) AS rounded_amount
FROM orders;

Business scenario: Finalize charges by rounding up partial order payments.

2. Find Customers With Next-Whole Purchases

SELECT customer_id, purchase_total,
       CEILING(purchase_total / 10) * 10 AS next_whole_bill
FROM customers;

Business scenario: Prepare special invoices at the next multiple of 10 for loyalty members.

3. Inventory Restock Rounding

SELECT product_name, current_stock,
       reorder_quantity, CEILING(reorder_quantity) AS reorder_rounded
FROM products
WHERE needs_restock = TRUE;

Business scenario: Ensure you always round up item restock quantities.
