PIVOT in Oracle - Examples & AI Generator

The PIVOT function in Oracle lets you transform row data into columns, making complex reporting easier but often tricky to craft by hand. Oracle’s PIVOT syntax is distinct and detailed, requiring precise aggregation, column aliasing, and static value listing. For SQL developers and analysts working across databases, memorizing Oracle PIVOT syntax slows productivity. AI2sql eliminates this friction, converting plain-English requests into error-free PIVOT queries, no coding required, in just 10 seconds.

PIVOT Syntax in Oracle

Oracle PIVOT Statement Structure

• SELECT ... FROM ... PIVOT (...) is Oracle’s native approach.

• Specify aggregation functions (like SUM, COUNT) and value lists.

• Column names for pivoted results must be explicitly listed.

SELECT * FROM 
  (SELECT customer_id, product, sales FROM orders)
PIVOT (
  SUM(sales) FOR product IN ('Laptop' AS LAPTOP, 'Tablet' AS TABLET)
);

Note: Oracle requires static value enumeration in the IN (...) clause, unlike some other databases.

FAQ: PIVOT in Oracle

• Q: Can I dynamically pivot unknown values in Oracle?
  A: Oracle’s PIVOT requires explicit listing of all pivot values in the IN clause. For dynamic columns, use dynamic SQL with native PL/SQL.

• Q: What if my data contains NULLs?
  A: Aggregations for missing values in PIVOT output NULL by default.

• Q: How is Oracle PIVOT different from other databases?
  A: Unlike SQL Server, Oracle needs pivot values predefined and formatted using its specific PIVOT clause structure.
