pg_query

(PHP 4 >= 4.2.0, PHP 5)

pg_query — Execute a query

Описание

resource pg_query ( string $query )
resource pg_query ( resource $connection , string $query )

pg_query() executes the query on the specified database connection .

If an error occurs, and FALSE is returned, details of the error can be retrieved using the pg_last_error() function if the connection is valid.

Замечание: Although connection can be omitted, it is not recommended, since it can be the cause of hard to find bugs in scripts.

Замечание: This function used to be called pg_exec(). pg_exec() is still available for compatibility reasons, but users are encouraged to use the newer name.

Список параметров

connection

PostgreSQL database connection resource. When connection is not present, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().

query

The SQL statement or statements to be executed. When multiple statements are passed to the function, they are automatically executed as one transaction, unless there are explicit BEGIN/COMMIT commands included in the query string. However, using multiple transactions in one function call is not recommended.

Возвращаемые значения

A query result resource on success, or FALSE on failure.

Примеры

Пример #1 pg_query() example

<?php

$conn 
pg_pconnect("dbname=publisher");
if (!
$conn) {
  echo 
"An error occured.\n";
  exit;
}

$result pg_query($conn"SELECT author, email FROM authors");
if (!
$result) {
  echo 
"An error occured.\n";
  exit;
}

while (
$row pg_fetch_row($result)) {
  echo 
"Author: $row[0]  E-mail: $row[1]";
  echo 
"<br />\n";
}
 
?>

Пример #2 Using pg_query() with multiple statements

<?php

$conn 
pg_pconnect("dbname=publisher");

// these statements will be executed as one transaction

$query "UPDATE authors SET author=UPPER(author) WHERE id=1;";
$query .= "UPDATE authors SET author=LOWER(author) WHERE id=2;";
$query .= "UPDATE authors SET author=NULL WHERE id=3;";

pg_query($conn$query);

?>
