# Class 02 — No Data (this is also a warning class per the SQL standard)

## Shared meaning {#meaning}

The first two characters `02` identify `No Data (this is also a warning class per the SQL standard)`. A statement completed without returning the requested data. A class gives a directory-level family; each member still needs its own message, transaction aftermath, and response evidence.

## Members {#members}

The locked catalogue contains 2 members in this class:

[`02000`](../../02000/), [`02001`](../../02001/)

## Version boundary {#versions}

Member links lead to their own versioned facts; consult the version pages and source evidence for exact presence and change boundaries.

## Sources {#sources}

Members are generated from `data/classes.json` and the locked SQLSTATE directory.
