ARRAY_AGG in Oracle - Examples & AI Generator
The ARRAY_AGG function in Oracle lets you collect column values into a single array—especially useful for aggregating rows into lists or arrays by group. But, Oracle’s ARRAY_AGG
syntax differs from other databases, making it hard to remember the nuances, especially if you work across SQL dialects.
AI2sql eliminates the guesswork—simply type your query in natural language and get production-ready Oracle SQL in seconds, no manual coding required.
ARRAY_AGG Syntax in Oracle
Oracle ARRAY_AGG syntax lets you aggregate values into an array, supporting both distinct and order specifications:
DISTINCT: Remove duplicate values
ORDER BY: Control element order inside the aggregate array
Oracle difference: Unlike PostgreSQL or SQL Server, Oracle’s ARRAY_AGG
often returns a VARRAY or a nested collection instead of a simple delimited string.
