To find the gaps in a sequence of IDs from 1 to 999 in a SQL table, you can use a query that identifies missing numbers within that range. Here's a general approach using common table expressions (CTEs) and the NOT EXISTS clause:
WITH RECURSIVE Numbers AS (SELECT 1 AS idUNION ALLSELECT id + 1FROM NumbersWHERE id < 999),ExistingIDs AS (SELECT idFROM your_table_nameWHERE id BETWEEN 1 AND 999),MissingIDs AS (SELECT idFROM NumbersWHERE NOT EXISTS (SELECT 1FROM ExistingIDsWHERE ExistingIDs.id = Numbers.id))SELECT idFROM MissingIDs;
Replace your_table_name with the name of your table. This query generates a series of numbers from 1 to 999 using a recursive CTE, then checks against your table to find which numbers are missing within that range.
It's work for me perfectlydose any body have more short query please sujjest me
