# ABORT

## Name

ABORT -- abort the current transaction

## Synopsis

    ABORT [ WORK | TRANSACTION ]

## Description

`ABORT` rolls back the current transaction and causes all the updates made by the transaction to be discarded. This command is identical in behavior to the standard SQL command ROLLBACK, and is present only for historical reasons.

## Parameters

`WORK`
`TRANSACTION`

  Optional key words. They have no effect.

## Notes

Use COMMIT to successfully terminate a transaction.

Issuing `ABORT` outside of a transaction block emits a warning and otherwise has no effect.

## Examples

To abort all changes:

    ABORT;

## Compatibility

This command is a PostgreSQL extension present for historical reasons. `ROLLBACK` is the equivalent standard SQL command.
