整数数组PLPGSQL抛出错误在PostgreSQL的9.1，但9.3

的作品我有这样的功能：整数数组PLPGSQL抛出错误在PostgreSQL的9.1，但9.3

CREATE OR REPLACE FUNCTION check_presence_row(
    _id_att_files integer[], 
    _people_name character varying, 
    _people_id character varying, 
    _time_start timestamp without time zone, 
    _time_end timestamp without time zone 
) 
RETURNS integer[] AS $BODY$ 
DECLARE 
    ids integer array; 
BEGIN 
    ids := (SELECT "id_att_file"FROM att_presence WHERE 
     "id_att_file" = ANY ("_id_att_files") AND 
     "id_people" = get_people(
       "_people_id", 
       "_people_name") AND 
     "time_start" = "_time_start" AND 
     "time_end" = "_time_end"); 

    RETURN ids; 
END;$BODY$ 
LANGUAGE plpgsql VOLATILE 
COST 100;

当我把它在PostgreSQL的版本9.3这样：

SELECT check_presence_row(
    CAST ('{1,4}' AS int[]), 
    CAST ('Random Guy' AS varchar), 
    CAST ('D0388A' AS varchar), 
    CAST ('2014/08/23 8:04:00' AS timestamp without time zone), 
    CAST ('2014/08/23 8:34:00' AS timestamp without time zone) 
);

它运行正常，并根据需要返回结果，但在9.1当我发送相同的查询时会抛出一个错误：

ERROR: array value must start with "{" or dimension information 
CONTEXT: PL/pgSQL function "check_presence_row" line 5 at assignment 
********** Error ********** 

ERROR: array value must start with "{" or dimension information 
SQL state: 22P02 
Context: PL/pgSQL function "check_presence_row" line 5 at assignment

我发现，当该数组的任何输入值正好是1它以这种方式失败，但如果我将它们更改为一些不同的整数值传递....但只在我的本地主机。我们的生产服务器仍然无法通过任何价值。我们尝试了另一台计算机，即使值为1，也通过了一台计算机。有任何想法吗？

奇怪的问题。你认为你可以简化为http://sqlfiddle.com/？ – 2014-09-25 14:19:56

没关系，我只是找到了原因。它是由那个id：= assignemnt引起的，因为我在att_files中只有一行（这就是为什么在我的电脑上它与I 1失败） – 2014-09-25 14:57:56

很好的自我回答。 – 2014-09-25 15:04:58

错误警报，我刚发现它是由该ID：=赋值引起的。因为我在att_file表中有一行id = 1，所以它在我的本地主机上出错了，而另一台具有空DB的计算机则没有。我改变了返回不通过该变量，但只能查询，而不是：

CREATE OR REPLACE FUNCTION check_presence_row(
    _id_att_files integer[], 
    _people_name character varying, 
    _people_id character varying, 
    _time_start timestamp without time zone, 
    _time_end timestamp without time zone 
) 
RETURNS SETOF integer AS 
$BODY$ 
BEGIN 
    RETURN QUERY SELECT "id_att_file"FROM att_presence WHERE 
     "id_att_file" = ANY ("_id_att_files") AND 
     "id_people" = get_people(
      "_people_id", 
      "_people_name") AND 
     "time_start" = "_time_start" AND 
     "time_end" = "_time_end"; 
END;$BODY$ 
LANGUAGE plpgsql
