pg_transaction_status

(PHP 5)

pg_transaction_status -- Returns the current in-transaction status of the server.

说明

int pg_transaction_status ( resource connection )

Returns the current in-transaction status of the server.

注意

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.

例子 1. pg_transaction_status() example

<?php
  $dbconn
= pg_connect("dbname=publisher") or die("Could not connect");
 
$stat = pg_transaction_status($dbconn);
  if (
$stat === PGSQL_TRANSACTION_UNKNOWN) {
     echo
'Connection is bad';
  } else if (
$stat === PGSQL_TRANSACTION_IDLE) {
     echo
'Connection is currently idle';
  } else {
     echo
'Connection is in a transaction state';
  }   
?>
