pg_transaction_status
(PHP 5 >= 5.1.0, PHP 7)
pg_transaction_status — Returns the current in-transaction status of the server
说明
$connection
) :
int
Returns the current in-transaction status of the server.
pg_transaction_status() will give incorrect results when using a PostgreSQL 7.3 server that has the parameter autocommit set to off. The server-side autocommit feature has been deprecated and does not exist in later server versions.
参数
-
connection
-
PostgreSQL database connection resource.
返回值
The status can be PGSQL_TRANSACTION_IDLE
(currently idle), PGSQL_TRANSACTION_ACTIVE
(a command is in progress), PGSQL_TRANSACTION_INTRANS
(idle, in a valid transaction block), or PGSQL_TRANSACTION_INERROR
(idle, in a failed transaction block). PGSQL_TRANSACTION_UNKNOWN
is reported if the connection is bad. PGSQL_TRANSACTION_ACTIVE
is reported only when a query has been sent to the server and not yet completed.
