Get error message associated with result

Описание

string pg_result_error (resource result)

pg_result_error() returns any error message

associated with the result resource. Therefore,

the user has a better chance of getting the correct error message than

with pg_last_error().

The function pg_result_error_field() can give much greater

detail on result errors than pg_result_error().

Because pg_query() returns FALSE if the query fails,

you must use pg_send_query() and

pg_get_result() to get the result handle.

Список параметров

result

PostgreSQL query result resource, returned by pg_query(),

pg_query_params() or pg_execute()

(among others).

offset

Row to move the internal offset to in the result resource.

Rows are numbered starting from zero.

Возвращаемые значения

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

Примеры

Пример 1. pg_result_seek() example


<?php

// Connect to the database
$conn = pg_pconnect("dbname=publisher");

// Execute a query
$result = pg_query($conn, "SELECT author, email FROM authors");

// Seek to the 3rd row (assuming there are 3 rows)
pg_result_seek($result, 2);

// Fetch the 3rd row
$row = pg_fetch_row($result);

?>
