pg_result_error

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

    pg_result_error — Get error message associated with result

    Descrição

    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.

    Parâmetros

    result

    Uma instância de PgSql\Result, retornada por pg_query(), pg_query_params() ou pg_execute() (entre outras).

    Valor Retornado

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

    Registro de Alterações

    VersãoDescrição
    8.1.0 O parâmetro result agora espera uma instância de PgSql\Result; anteriormente, um resource era esperado.
