【问题描述】：

我正在尝试执行此功能：

CREATE OR REPLACE FUNCTION "SA_PRJ".usp_verify_allocated_time(p_uid integer, p_project_id integer,   p_allocated_time numeric, p_achieved_time numeric, p_task_desc character varying, p_obs character  varying, p_date timestamp without time zone)
RETURNS void AS

$BODY$
declare alloc_id integer;

BEGIN
   if not "SA_ADM".usp_check_permission(p_uid, 'SA_PRJ', 'usp_add_timesheet_record') then
    raise exception 'User ID % nu are permisii pentru aceasta operatie!', p_uid;
   end if;
SELECT *,
   case when SUM(fld_allocated_time) / 24 < fld_allocated_days 
then 
   INSERT INTO "SD_PRJ".tbl_project_timesheet(fld_emp_id, fld_project_id,        fld_is_allocated,fld_allocated_time, fld_achieved_time,    fld_task_desc, fld_obs)
    VALUES (p_uid,p_project_id,coalesce(alloc_id,0), p_allocated_time, p_achieved_time,p_task_desc, p_obs);

else 'Not OK' 
end as Alocated
from
(
  SELECT p.fld_id, p.fld_allocated_days, t.fld_allocated_time
  FROM "SD_PRJ".tbl_project p
  INNER JOIN "SD_PRJ".tbl_project_timesheet t
  ON p.fld_id=t.fld_id
  where t.fld_project_id = p_project_id
)AS Alias
GROUP BY fld_id, fld_allocated_days, fld_allocated_time
END;

$BODY$
LANGUAGE plpgsql VOLATILE
COST 100;
ALTER FUNCTION "SA_PRJ".usp_usp_verify_allocated_time(integer, integer, numeric, numeric, character varying,   character varying, timestamp without time zone)
OWNER TO postgres;

我想创建一个函数来连接表 "SD_PRJ".tbl_project 和 "SD_PRJ".tbl_project_timesheet 中的两列并进行比较 SUM(fld_allocated_time) / 24 < fld_allocated_days 从输入参数p_project_id (WHERE t.fld_project_id = p_project_id) 中插入是否正常。

输入列 fld_project_id 可以有超过 1 个出现在表中。

tbl_ = table name
fld_ = column / field name

"SD_PRJ" = my schema name
\ERROR:  syntax error at or near "INTO"

错误：

第 12 行：插入“SD_PRJ”.tbl_project_timesheet(fld_emp_id, fl... ^

【问题讨论】：

插入它的错误对不起错误:)
您的错误是因为您无法在 select 语句中插入。而是尝试将您的案例值放入变量中，并根据 if 语句中的变量值确定是否应该插入。

【解决方案1】：

是的，您正在尝试在 select 语句中编写 insert。

你可能想要的是这样的：

INSERT INTO "SD_PRJ".tbl_project_timesheet(fld_emp_id, fld_project_id,        fld_is_allocated,fld_allocated_time, fld_achieved_time,    fld_task_desc, fld_obs)
select p_uid,p_project_id,coalesce(alloc_id,0), p_allocated_time, p_achieved_time,p_task_desc, p_obs
from
(
  SELECT p.fld_id, p.fld_allocated_days, t.fld_allocated_time
  FROM "SD_PRJ".tbl_project p
  INNER JOIN "SD_PRJ".tbl_project_timesheet t
  ON p.fld_id=t.fld_id
  where t.fld_project_id = p_project_id
)AS Alias
GROUP BY fld_id, fld_allocated_days, fld_allocated_time
having SUM(fld_allocated_time) / 24 < fld_allocated_days

不完全确定一切是否正确，但我认为这就是它的一般要点。
