How to insert records using select statement? Hi I am working on one project, here what I am trying is, I want to insert records what I get using select statements into temp table. but it is giving error to me, can any one help me to solve this ?
ERROR:  relation &quot;temp_mytbl&quot; does not exist
SQL state: 42P01
following is my query
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) &gt;= idm.start_dte AND soar_date(a.calendar_date_key) &lt;= 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) &gt;= idm.start_dte 
                               AND soar_date(a.calendar_date_key) &lt;= 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;

or the same in subquery form
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 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) &gt;= idm.start_dte 
                               AND soar_date(a.calendar_date_key) &lt;= COALESCE(idm.end_dte, now()::date)
GROUP BY i.dte, idm.empl_id 
ORDER BY i.dte
LIMIT 100;
