pg_result_error

    (PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)

    pg_result_error — Get error message associated with result

    Descripción

    pg_result_error(PgSql\Result$result): string|false

    pg_result_error() returns any error message associated with the result instance. 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.

    Parámetros

    result

    An PgSql\Result instance, returned by pg_query(), pg_query_params() or pg_execute()(among others).

    Valores devueltos

    Returns a string. Returns empty string if there is no error. If there is an error associated with the result parameter, returns false.
