Meine Datenbank ist PostgreSQL, und ich möchte Sphinx Search Engines verwenden, um meine Daten zu indizieren;Verwendung der Unterabfrage In den mehrwertigen Attributen (MVA) von Sphinx für die Abfrage
Wie kann ich sql_attr_multi verwenden, um die Beziehungsdaten abzurufen?
Die Tabellen in postgresql, Schemata ist:
crm=# \d orders
Table "orders"
Column | Type | Modifiers
-----------------+-----------------------------+----------------------------------------
id | bigint | not null
trade_id | bigint | not null
item_id | bigint | not null
price | numeric(10,2) | not null
total_amount | numeric(10,2) | not null
subject | character varying(255) | not null default ''::character varying
status | smallint | not null default 0
created_at | timestamp without time zone | not null default now()
updated_at | timestamp without time zone | not null default now()
Indexes:
"orders_pkey" PRIMARY KEY, btree (id)
"orders_trade_id_idx" btree (trade_id)
crm=# \d trades
Table "trades"
Column | Type | Modifiers
-----------------------+-----------------------------+---------------------------------------
id | bigint | not null
operator_id | bigint | not null
customer_id | bigint | not null
category_ids | bigint[] | not null
total_amount | numeric(10,2) | not null
discount_amount | numeric(10,2) | not null
created_at | timestamp without time zone | not null default now()
updated_at | timestamp without time zone | not null default now()
Indexes:
"trades_pkey" PRIMARY KEY, btree (id)
Die config Sphinx ist:
source trades_src
{
type = pgsql
sql_host = 10.10.10.10
sql_user = ******
sql_pass = ******
sql_db = crm
sql_port = 5432
sql_query = \
SELECT id, operator_id, customer_id, category_ids, total_amount, discount_amount, \
date_part('epoch',created_at) AS created_at, \
date_part('epoch',updated_at) AS updated_at \
FROM public.trades;
#attributes
sql_attr_bigint = operator_id
sql_attr_bigint = customer_id
sql_attr_float = total_amount
sql_attr_float = discount_amount
sql_attr_multi = bigint category_ids from field category_ids
#sql_attr_multi = bigint order_ids from query; SELECT id FROM orders
#how can i add where condition is the query for orders? eg. WHERE trade_id = ?
sql_attr_timestamp = created_at
sql_attr_timestamp = updated_at
}
I MVA (multi-valued attributes) auf category_ids
Feld verwendet wird, und es ist der Typ ARRAY in Postgresql.
Aber ich weiß nicht Wie MVA auf order_ids zu definieren. Es wird durch Unterabfrage sein?
Danke mach variieren :) es funktionierte gut – Fish
