Question

我在PostgreSQL中有一个名为users的表。我希望从我的Laravel应用程序中获取表中的所有用户。

我可以直接从表中获取：

$testData = DB::table('users')->get();

输出是：

通过PostgreSQL函数调用：

我的PostgreSQL功能：

-- Function: public."RegiterUsers2"()

-- DROP FUNCTION public."RegiterUsers2"();

CREATE OR REPLACE FUNCTION public."RegiterUsers2"()
  RETURNS SETOF users AS
'select * from users'
  LANGUAGE sql VOLATILE
  COST 100
  ROWS 1000;
ALTER FUNCTION public."RegiterUsers2"()
  OWNER TO postgres;

Laravel代码：

$allUserData=DB::select('SELECT public."RegiterUsers2"()')

输出：

[{"RegiterUsers2":"(1,\"Chris Sevilleja\",sevilayha,chris@scotch.io,$2y$08$i\/ATa68ierqRL47ZxHX4EesJGEcdtKPckZs8GDGpYS.IR4aaQn.\/q,\"2016-09-07 09:32:41\",\"2016-09-07 09:32:41\")"},{"RegiterUsers2":"(2,\"Bemagoni chandrashekar\",chandrashekar,chandrashekar@zessta.com,$2y$08$QG9JsAerYp3UYpXNNyImhuz\/6hiWv8XpURpJX1uJ.hAm8l1RG2JrC,\"2016-09-07 09:32:41\",\"2016-09-07 09:32:41\")"},{"RegiterUsers2":"(3,dwefr,ewre,ewrt@egyfrhgt.com,$2y$08$s2XBZvoAvpEqjjhbx8QPw.eSe5TIuJC25XbaFkTskzAKAGi99QWga,\"2016-09-07 09:34:27\",\"2016-09-07 09:34:27\")"},{"RegiterUsers2":"(4,r3t54y6u677i,retrytyu,etyru@dddj.com,$2y$08$Xb0Xm4KwdSwcBSHX0F6ETOWU60X.NO5D7\/uwVv\/xUAXTUS8LSPCLu,\"2016-09-07 09:46:26\",\"2016-09-07 09:46:26\")"},{"RegiterUsers2":"(5,r3t45y6u,ertrh,435t4y65@sss.com,$2y$08$36DLu49nZ2YOWtU.c625meiyi3\/fmsHxiTuxIU9z9UcyrbIpFSKKW,\"2016-09-07 10:02:05\",\"2016-09-07 10:02:05\")"},{"RegiterUsers2":"(6,ewrtryuyj,ryt,wrewtey@sssks.com,$2y$08$GULHtX3GGXPGgm8gA9yDbeawZlQ5QwD2TX7nrCvEU4j7jrSgPWAQO,\"2016-09-07 10:04:17\",\"2016-09-07 10:04:17\")"},{"RegiterUsers2":"(7,chandu,chandu,ch1235hdhd@dhdjd.com,$2y$08$gpAhcl\/Sg.lGvb.zk.I\/m.PfcttGI6OPFMsMxQVm15dYOtQDvIWSG,\"2016-09-07 10:06:18\",\"2016-09-07 10:06:18\")"},{"RegiterUsers2":"(8,dewfergt,erwrgf,fgf@dgrf.com,$2y$08$ikYAXV1prZsEj2MPxXM4S.Tqn160Jv25cFOQLghK8ptFiSBaIFGZO,\"2016-09-07 10:07:20\",\"2016-09-07 10:07:20\")"},{"RegiterUsers2":"(9,rteryt,wrwter,wretr@gjjd.com,$2y$08$pkOUBl1NlNdBShNWiklya.0zlPzPrEH2edCfvdCiHLnj80GY1sdtm,\"2016-09-08 07:11:46\",\"2016-09-08 07:11:46\")"},{"RegiterUsers2":"(10,Raghu,raghu,raghu@gdgdjd.com,$2y$08$m9wke.vvTTZytYw91I4\/q.qxKoCobLOW7dbCvs66xFyJyy2R9phni,\"2016-09-10 10:06:40\",\"2016-09-10 10:06:40\")"},{"RegiterUsers2":"(11,wewert,ewretr,ewrtey@vsss.com,$2y$08$IXD0eXYTPPGE1MfALonEFey0lr\/KBMZ0.3AIO3sWVgu7IZdWhXwTG,\"2016-09-12 07:48:58\",\"2016-09-12 07:48:58\")"}]

我需要这样

    {"id":1,
"name":"Chris Sevilleja",
"username":"sevilayha",
"email":"chris@scotch.io",
"password":"$2y$08$i\/ATa68ierqRL47ZxHX4EesJGEcdtKPckZs8GDGpYS.IR4aaQn",
"created_at":"2016-09-07 09:32:41",
"updated_at":"2016-09-07 09:32:41"},

所以postgres函数出了什么问题，我怎样才能达到上述功能。

Answer 1

当您调用函数返回许多列并且您想要每个列时，您必须以以下形式调用：

SELECT col1, col2, ... FROM function(...)

或者：

SELECT * FROM function(...)

所以在你的情况下，你只需要：

$allUserData=DB::select('SELECT * FROM public."RegiterUsers2"()')

PostgreSQL函数给出所有行但不是键值对格式？
