Dette ville svare til tidligere svar på plsql-procedure gentagen kodelinje. forsøger at gøre det på en bedre måde .
Det, vi gør nu, er at tilføje JOIN
til tabel indeholdende batch_run_details
og case, der bestemmer for hver række, hvilken handling den skal indsætte baseret på creation_date
og max_last_update_date
.
CREATE OR REPLACE PROCEDURE update_dynamic_entity(p_entity_type VARCHAR2 DEFAULT NULL,
p_update_mode VARCHAR2) IS
BEGIN
IF lower(p_update_mode) <> 'incremental'
THEN
RETURN; -- Do nothing if incorrect mode
END IF;
--
INSERT INTO dynamicentitygtt
(entity_type, entity_id, entity_code, synonyms, action)
SELECT upper(NVL(p_entity_type, 'ITEM')),
t.item_id,
t.item_name,
t.item_desc,
CASE
WHEN t.creation_date > b.max_last_update_date THEN
'update'
WHEN t.creation_date < b.max_last_update_date THEN
'add'
END
FROM itemde t
JOIN batch_run_details b
ON b.entity_type = 'ITEM'
WHERE upper(p_entity_type) = 'ITEM'
OR p_entity_type IS NULL;
--
INSERT INTO dynamicentitygtt
(entity_type, entity_id, entity_code, synonyms, action)
SELECT upper(NVL(p_entity_type, 'ORG')),
t.org_id,
t.org_name,
t.org_desc,
CASE
WHEN t.creation_date > b.max_last_update_date THEN
'update'
WHEN t.creation_date < b.max_last_update_date THEN
'add'
END
FROM orgde t
JOIN batch_run_details b
ON b.entity_type = 'ORG'
WHERE upper(p_entity_type) = 'ORG'
OR p_entity_type IS NULL;
END update_dynamic_entity;
Og kun til afslutning fra forrige indlæg, enkelt indsættelsesversion også:
CREATE OR REPLACE PROCEDURE update_dynamic_entity(p_entity_type VARCHAR2 DEFAULT NULL,
p_update_mode VARCHAR2) IS
BEGIN
IF lower(p_update_mode) <> 'incremental'
THEN
RETURN;
END IF;
--
INSERT INTO dynamicentitygtt
(entity_type, entity_id, entity_code, synonyms, action)
WITH data_view AS
( -- ITEM table
SELECT 'ITEM' entity_type, -- This separates inserted values
item_id data_id,
item_name data_name,
item_desc data_desc,
creation_date
FROM itemde
UNION ALL
-- ORG table
SELECT 'ORG' entity_type, -- This separates inserted values
org_id,
org_name,
org_desc,
creation_date
FROM orgde
-- NEXT entity table
)
SELECT upper(t.entity_type),
t.data_id,
t.data_name,
t.data_desc,
CASE
WHEN t.creation_date > b.max_last_update_date THEN
'update'
WHEN t.creation_date < b.max_last_update_date THEN
'add'
END
FROM data_view t
JOIN batch_run_details b
ON b.entity_type = t.entity_type
WHERE upper(p_entity_type) = t.entity_type
OR p_entity_type IS NULL;
END update_dynamic_entity;
