我想将给定的日期和整数转换为pl / pgsql函数中的时间戳。我以前从未对pl / pgsql做过任何事情,所以我有些不知所措。
感谢Pablo Santa Cruz的回答,它达到了这个目的:
CREATE OR REPLACE FUNCTION to_my_timestamp(mydate date, timeint integer) RETURNS timestamp AS $$
DECLARE
myhours integer := timeint / 10000;
myminutes integer := timeint % 10000 / 100;
myseconds integer := timeint % 100;
timestring text := myhours || ':' || myminutes || ':' || myseconds;
BEGIN
RETURN (mydate::text || ' ' || timestring)::timestamp;
$$ LANGUAGE plpgsql;
select to_my_timestamp('2010-08-12',123456);
然而,这对我来说似乎并不适用。这是我在Ubuntu上使用pgadmin3时出现的错误:
ERROR: syntax error at end of input
LINE 9: $$ LANGUAGE plpgsql;
^
********** Error **********
ERROR: syntax error at end of input
SQL state: 42601
Character: 377
非常感谢任何帮助:)

尝试将返回值更改为:
RETURN (mydate::text || ' ' || timestring)::timestamp;

你错过了END;
:
CREATE OR REPLACE FUNCTION to_my_timestamp(mydate date, timeint integer) RETURNS timestamp AS $$
DECLARE

myminutes integer := timeint % 10000 / 100;
myseconds integer := timeint % 100;
timestring text := myhours || ':' || myminutes || ':' || myseconds;
BEGIN
