LISTAGG in PostgreSQL - Examples & AI Generator
The LISTAGG function in PostgreSQL is a powerful way to concatenate values from multiple rows into a single, delimited string. But its syntax—especially with window functions and ordered results—can be complex and time-consuming to memorize or adapt between database platforms. AI2sql removes this friction instantly, letting you turn natural language into production-ready PostgreSQL LISTAGG queries—with no coding required.
LISTAGG Syntax in PostgreSQL
Basic Syntax
column: Data you want to concatenate.
delimiter: String separator (e.g., ', ').
WITHIN GROUP: Mandatory ordering for concatenation.
OVER: Used for windowed aggregations (optional).
Note: PostgreSQL requires WITHIN GROUP (ORDER BY ...)
for LISTAGG, differing from some databases.
