Question

我有一个for php，我希望将它包含在postgre函数中，但我无法将其翻译为postgre。我们的想法是将日期1和日期2之间的日期范围放在索引是同一日期的数组中。提前谢谢。

我在php中的代码：

$meses_intermedios = array();

for ($e = '2016-03-01'; $e <= '2017-07-01'; $e = date("Y-m-d", strtotime($e . "+ 1 month"))) {
    //From the date '2016-03-01' to the date '2017-07-01', I accumulate the intermediate dates
         $meses_intermedios[$e] = $e;
    }

预期结果应为

$meses_intermedios['2016-03-01'] => 2016-03-01
$meses_intermedios['2016-04-01'] => 2016-04-01
$meses_intermedios['2016-05-01'] => 2016-05-01
$meses_intermedios['2016-06-01'] => 2016-06-01
$meses_intermedios['2016-07-01'] => 2016-07-01
$meses_intermedios['2016-08-01'] => 2016-08-01
$meses_intermedios['2016-09-01'] => 2016-09-01
$meses_intermedios['2016-10-01'] => 2016-10-01
$meses_intermedios['2016-11-01'] => 2016-11-01
$meses_intermedios['2016-12-01'] => 2016-12-01
$meses_intermedios['2017-01-01'] => 2017-01-01
$meses_intermedios['2017-02-01'] => 2017-02-01
$meses_intermedios['2017-03-01'] => 2017-03-01
$meses_intermedios['2017-04-01'] => 2017-04-01
$meses_intermedios['2017-05-01'] => 2017-05-01
$meses_intermedios['2017-06-01'] => 2017-06-01

好的，如果它为某人服务......解决方案：

CREATE OR REPLACE FUNCTION testing.bucle_date_array(
    start_date date,
    end_date date)
RETURNS date[]
    LANGUAGE 'plpgsql'
    COST 100
    VOLATILE 
    ROWS 0
AS $BODY$

DECLARE
date_exe date := start_date;
array_date date[];
BEGIN

WHILE date_exe <= end_date
LOOP
    -- MAKE YOUR STUFF
    RAISE NOTICE '%', date_exe;
    array_date := array_append(array_date,date_exe);
    date_exe := date_exe + interval '1 month';
END LOOP;

RETURN array_date;

END;

$BODY$;

for php to Postgres FOR LOOP
