## 例

`

     string pg_result_error ( resource $result )

`

## 説明

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.

## 戻り値

Returns a string if there is an error associated with the result parameter, FALSE otherwise.
