# COMMIT — commit the current transaction

## Synopsis

```
COMMIT [ WORK | TRANSACTION ] [ AND [ NO ] CHAIN ]
```

<a id="id-1.9.3.54.5"></a>

## Description

`COMMIT` commits the current transaction. All changes made by the transaction become visible to others and are guaranteed to be durable if a crash occurs. 

If the transaction is in an aborted state then no changes will be made and the effect of the `COMMIT` will be identical to that of `ROLLBACK`, including the command tag output. 

In either case, if the `AND CHAIN` parameter is specified then a new, identically configured, transaction is started. 

For more information regarding transactions see [Section 3.4](tutorial-transactions.md).

## Parameters

<a id="sql-commit-transaction"></a>

**`WORK`**, **`TRANSACTION`**

 Optional key words. They have no effect. <a id="sql-commit-chain"></a>

**`AND CHAIN`**

 If `AND CHAIN` is specified, a new transaction is immediately started with the same transaction characteristics (see [SET TRANSACTION](sql-set-transaction.md)) as the just finished one. Otherwise, no new transaction is started. <a id="id-1.9.3.54.7"></a>

## Outputs

On successful completion of a non-aborted transaction, a `COMMIT` command returns a command tag of the form 
COMMIT
 

However, in an aborted transaction, a `COMMIT` command returns a command tag of the form 
ROLLBACK

## Notes

Use [ROLLBACK](sql-rollback.md) to abort a transaction. 

Issuing `COMMIT` when not inside a transaction does no harm, but it will provoke a warning message. `COMMIT AND CHAIN` when not inside a transaction is an error.

## Examples

To commit the current transaction and make all changes permanent: 
COMMIT;


<a id="id-1.9.3.54.10"></a>

## Compatibility

The command `COMMIT` conforms to the SQL standard, except that no exception condition is raised in the case where the transaction was already aborted. 

The form `COMMIT TRANSACTION` is a PostgreSQL extension.
