NAME
ABORT - 退出當前事務

PARAMETERS 參數

如果不在事務內部發出 ABORT 不會有問題，但是會產生一個警告信息。

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 [rollback(7)], and is present only for historical reasons.
PARAMETERS
- WORK
- TRANSACTION
- Optional key words. They have no effect.
NOTES
Use COMMIT [commit(7)] to successfully terminate a transaction.
Issuing ABORT when not inside a transaction does no harm, but it will provoke a warning message.
EXAMPLES
To abort all changes:
ABORT;
COMPATIBILITY
This command is a PostgreSQL extension present for historical reasons. ROLLBACK is the equivalent standard SQL command.
SEE ALSO
BEGIN [begin(7)], COMMIT [commit(l)], ROLLBACK [rollback(l)]
