pg_result_error

(PHP 4 >= 4.2.0, PHP 5)

pg_result_error -- 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); ?>
