我从早上开始就遇到了一个问题,花了很多时间,但未能调用给定的函数。

函数定义:

CREATE OR REPLACE FUNCTION public.proc_mc2cdnpf_insertupdatev3(
tblnotesv3 typupdate_notesv3,
tbldoclinks typupdate_guidparameter,
iuserid integer,
shtmltext character varying,
OUT snoteid character varying,
OUT inoteid integer,
OUT inoteactivityid integer)
RETURNS record
LANGUAGE 'plpgsql'

COST 100
VOLATILE
AS $BODY$
#variable_conflict use_variable
declare sNote VARCHAR;
declare sLoggedInUser VARCHAR(20);
declare dtCurrDateTime timestamp;
declare iCurrDate int;
declare iCurrTime INT;
declare iNewNoteID INT;

- Initial creation of new proc for storing additional HTML text value.
- This proc is going to help bridge the old note system to a new note storage method

2018-04-25
- Added iNoteID / iNoteActivityID for output

2018-06-01
- Update to typUpdate_NotesV3 - removed additional CDN rows for long text

我试图通过以下两种方式调用我的函数:

方法一:

SELECT public.proc_MC2CDNPF_InsertUpdateV3
(
(SELECT w::typupdate_notesv3 FROM (TABLE tblnotesv31) w ) ,
(SELECT w1::typupdate_guidparameter FROM (TABLE tbldoclinks1) w1 ) ,
1,
'test text'
)

但它失败并出现以下错误:

ERROR: query has no destination for result data HINT: If you want to discard the results of a SELECT, use PERFORM instead. CONTEXT: PL/pgSQL function proc_mc2cdnpf_insertupdatev3(typupdate_notesv3,typupdate_guidparameter,integer,character varying) line 41 at SQL statement SQL state: 42601

方法二:

SELECT * 
from proc_MC2CDNPF_InsertUpdateV3
(
(SELECT w::typupdate_notesv3 FROM (TABLE tblnotesv31) w ) ,
(SELECT w1::typupdate_guidparameter FROM (TABLE tbldoclinks1) w1 ) ,
1,
'test text'
)

它再次失败说:

ERROR: query has no destination for result data HINT: If you want to discard the results of a SELECT, use PERFORM instead. CONTEXT: PL/pgSQL function proc_mc2cdnpf_insertupdatev3(typupdate_notesv3,typupdate_guidparameter,integer,character varying) line 41 at SQL statement SQL state: 42601

有人可以帮我看看我的函数调用到底出了什么问题吗?

最佳答案

从第 41 行开始(正如错误消息告诉您的那样)您得到了:

SELECT dtCurrDateTime = fnGetDate();
SELECT iCurrDate = fnMC2DateToMC2(dtCurrDateTime);
SELECT iCurrTime = fnMC2DateTimeToMC2(dtCurrDateTime);

我假设您想在那里设置变量。但是你做错了。 (看起来你试图使用 SQL Server 语法。这是将函数从 SQL Server 移植到 Postgres 的尝试吗?还有 BEGIN ... END block 用于 IFs 和 ELSEs,它们在 Postgres 中是不必要的(但无害)但在 SQL Server 中是必需的。)

要么使用INTO:

SELECT fnGetDate() INTO dtCurrDateTime;
SELECT fnMC2DateToMC2(dtCurrDateTime) INTO iCurrDate;
SELECT fnMC2DateTimeToMC2(dtCurrDateTime) INTO iCurrTime;

或者,由于您实际上并不是在查询表,简单的赋值也应该有效:

dtCurrDateTime = fnGetDate();
iCurrDate = fnMC2DateToMC2(dtCurrDateTime);
iCurrTime = fnMC2DateTimeToMC2(dtCurrDateTime);

可能还有其他行有同样的错误,你应该检查整个代码。
