GENERATE SERIES in PostgreSQL - Examples & AI Generator

The GENERATE SERIES function in PostgreSQL is a flexible tool for producing numeric or date sequences directly in your queries. But remembering its parameters, step increments, and formatting—especially when you’re under pressure—can slow you down. AI2sql eliminates the hassle by turning plain-English prompts into error-free GENERATE SERIES queries—no coding required. If consistency and speed matter, let AI2sql handle PostgreSQL syntax for you in seconds.

GENERATE SERIES Syntax in PostgreSQL

Standard Numeric Sequence

SELECT generate_series(start, stop [, step]);

• start: First value in the series (integer or date).

• stop: Last value in the series.

• step (optional): Increment (default is 1).

Date & Timestamp Support

SELECT generate_series(start::timestamp, stop::timestamp, interval '1 day');
