如何使用 select 语句插入记录？

  • 772

嗨，我正在做一个项目，我正在尝试的是，我想将使用 select 语句得到的记录插入到临时表中。但它给我带来了错误，任何人都可以帮我解决这个问题吗？

错误：关系“temp_mytbl”不存在 SQL 状态：42P01

以下是我的查询

truncate table temp_mytbl;
create temporary table temp_mytbl as
select iex_id,dte,agent_name,schd_total
FROM source_xrx_iex6_sandy_1.iex6_agent_adh_sum  limit 0;

 insert into temp_mytbl
select iex_id,dte,agent_name,schd_total
FROM source_xrx_iex6_sandy_1.iex6_agent_adh_sum 
group by iex_id,dte,agent_name,schd_total;

SELECT i.dte,
    idm.empl_id,
    1 AS entity_id,
    sum(i.schd_total) AS s_schdhours
   FROM temp_mytbl i
     JOIN source_odw_usac.t_incontact_agentstatelog a ON a.winid = i.iex_id::text
     JOIN reporting_prod.idm_dte idm ON idm.src_id = a.agent_no AND idm.src_type_id = 618 AND soar_date(a.calendar_date_key) >= idm.start_dte AND soar_date(a.calendar_date_key) <= COALESCE(idm.end_dte, now()::date)
  GROUP BY i.dte, idm.empl_id limit 100;

    WITH temp_mytbl AS ( -- without aggregation in output expression / HAVING clause
                     -- GROUP BY must be replaced with DISTINCT
                     -- which is less expensive
                     SELECT DISTINCT iex_id, dte, agent_name, schd_total
                     FROM source_xrx_iex6_sandy_1.iex6_agent_adh_sum 
                   )
SELECT i.dte, idm.empl_id, 1 AS entity_id, SUM(i.schd_total) AS s_schdhours
FROM temp_mytbl i
JOIN source_odw_usac.t_incontact_agentstatelog a ON a.winid = i.iex_id::text
JOIN reporting_prod.idm_dte idm ON idm.src_id = a.agent_no 
                               AND idm.src_type_id = 618 
                               AND soar_date(a.calendar_date_key) >= idm.start_dte 
                               AND soar_date(a.calendar_date_key) <= COALESCE(idm.end_dte, now()::date)
GROUP BY i.dte, idm.empl_id /* , entity_id */ 
-- LIMIT without ORDER BY makes no sense
ORDER BY i.dte /* or another sorting expression */
LIMIT 100;

    或子查询形式相同

    SELECT i.dte, idm.empl_id, 1 AS entity_id, SUM(i.schd_total) AS s_schdhours
FROM ( SELECT DISTINCT iex_id, dte, agent_name, schd_total
       FROM source_xrx_iex6_sandy_1.iex6_agent_adh_sum 
     ) i
JOIN source_odw_usac.t_incontact_agentstatelog a ON a.winid = i.iex_id::text
JOIN reporting_prod.idm_dte idm ON idm.src_id = a.agent_no 
                               AND idm.src_type_id = 618 
                               AND soar_date(a.calendar_date_key) >= idm.start_dte 
                               AND soar_date(a.calendar_date_key) <= COALESCE(idm.end_dte, now()::date)
GROUP BY i.dte, idm.empl_id 
ORDER BY i.dte
LIMIT 100;

  2. create table #temp_mytbl (
 iex_id int,
 dte int,
 agent_name varchar(10),
 schd_total float
 )

 insert into #temp_mytbl
select iex_id,dte,agent_name,schd_total
FROM source_xrx_iex6_sandy_1.iex6_agent_adh_sum 
group by iex_id,dte,agent_name,schd_total;

SELECT i.dte,
    idm.empl_id,
    1 AS entity_id,
    sum(i.schd_total) AS s_schdhours
   FROM #temp_mytbl i
     JOIN source_odw_usac.t_incontact_agentstatelog a ON a.winid = i.iex_id::text
     JOIN reporting_prod.idm_dte idm ON idm.src_id = a.agent_no AND idm.src_type_id = 618 AND soar_date(a.calendar_date_key) >= idm.start_dte AND soar_date(a.calendar_date_key) <= COALESCE(idm.end_dte, now()::date)
  GROUP BY i.dte, idm.empl_id limit 100;


  DROP TABLE #temp_mytbl
