ich war in der Lage zu erreichen, was verwenden psql Ich war auf der Suche für CTEs statt für temporäre Tabellen ... eine lange Kette von CTEs (die als temporäre Tabellen fungieren), die in die Hauptabfrage eintauchen.
Ein einfaches Beispiel:
with first as (
select 1 as col
),
second as (
select 2 as col
)
select * from first union all select * from second
Ein komplexeres Beispiel:
with COGS as (
select 'Product1' Vertical, 3.0 Credit, 1.00 Debit, 2.75 Blend, 4.30 Amex, 0.25 ACH union
select 'Product2', 3.1, 2.2, 2.8, 4.5, 0.25 union
),
Allocable_Card_Volume as (
select MPR.Date, sum(MPR.Card_Volume_Net_USD) Allocable_Card_Volume
from mpr_base MPR
where MPR.Gateway in ('YapProcessing') and MPR.Vertical not in ('HA-Intl','HA')
group by MPR.Date
),
COGS_Financials_Base as (
select '2013-01-31'::DATE Date , 1000 Total_COGS , 200 Homeaway , (select Allocable_Card_Volume from Allocable_Card_Volume where Date in ('2013-01-31')) Allocable_Card_Volume union

sagte ich es komplex :-)
Vom feinen Handbuch http wäre: //www.postgresql .org/docs/9.5/static/sql-createtable.html 'Temporäre Tabellen werden automatisch am Ende einer Sitzung oder optional am Ende der aktuellen Transaktion gelöscht (siehe ON COMMIT unten)." – wildplasser
"Durch Abgrenzung .. Ich kann nicht gehen Dieses Script in Cron "- Entschuldigung, ich habe Probleme, das zu verstehen. Warum würde Cron von einer SQL-Skriptdatei betroffen sein? –
@RichardHuxton Ich habe ein Skript, das ich mit 'cron' planen möchte, dieses Skript erstellt einige temporäre Tabellen und führt dann Abfragen für diese temporären Tabellen aus. Wenn ich eine '' '- Beendigung benutze, führt das Skript nur die erste Abfrage aus (erste temporäre Tabelle), keine der nachfolgenden temporären Tabellen/resultierenden Abfragen wird ausgeführt –
