TRANSACTION_TIMESTAMP

Returns a value of type TIME WITH TIMEZONE that represents the start of the current transaction.

The return value does not change during the transaction. Thus, multiple calls to TRANSACTION_TIMESTAMP within the same transaction return the same timestamp.

TRANSACTION_TIMESTAMP is equivalent to CURRENT_TIMESTAMP, except it does not accept a precision parameter.

Behavior Type

Stable

Syntax

TRANSACTION_TIMESTAMP()

Example

=> SELECT foo, bar FROM (SELECT TRANSACTION_TIMESTAMP() AS foo)foo, (SELECT TRANSACTION_TIMESTAMP() as bar)bar;
              foo              |              bar
