整數數組PLPGSQL拋出錯誤在PostgreSQL的9.1，但9.3

的作品我有這樣的功能：整數數組PLPGSQL拋出錯誤在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;

當我把它在PostgreSQL的版本9.3這樣：

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) 
);

它運行正常，並根據需要返回結果，但在9.1當我發送相同的查詢時會拋出一個錯誤：

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

我發現，當該數組的任何輸入值正好是1它以這種方式失敗，但如果我將它們更改爲一些不同的整數值傳遞....但只在我的本地主機。我們的生產服務器仍然無法通過任何價值。我們嘗試了另一臺計算機，即使值爲1，也通過了一臺計算機。有任何想法嗎？

奇怪的問題。你認爲你可以簡化爲http://sqlfiddle.com/？ – 2014-09-25 14:19:56

沒關係，我只是找到了原因。它是由那個id：= assignemnt引起的，因爲我在att_files中只有一行（這就是爲什麼在我的電腦上它與I 1失敗） – 2014-09-25 14:57:56

很好的自我回答。 – 2014-09-25 15:04:58

錯誤警報，我剛發現它是由該ID：=賦值引起的。因爲我在att_file表中有一行id = 1，所以它在我的本地主機上出錯了，而另一臺具有空DB的計算機則沒有。我改變了返回不通過該變量，但只能查詢，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
