मैंने पहले भी ऐसा कुछ लिखा है, लेकिन अंत में प्रदर्शन के लिए इसका परीक्षण करने का मौका नहीं मिला।
डेटा को दो संबंधित तालिका में सम्मिलित करने के लिए मैंने एक एकल संग्रहीत प्रक्रिया और कुछ टी-एसक्यूएल चाल का उपयोग किया है जैसे टेबल वैल्यू पैरामीटर, मर्ज और आउटपुट क्लॉज।
यहां एक नमूना स्क्रिप्ट है:
सबसे पहले, नमूना तालिकाएँ बनाएँ:tblBase और tblRelated एक से अनेक विदेशी कुंजी से जुड़े हुए हैं।
CREATE TABLE tblBase
(
base_id int identity(1,1) primary key,
base_data int
);
CREATE TABLE tblRelated
(
related_base_id int foreign key references tblBase (base_id),
related_Id int identity(1,1) primary key,
related_data int
);
अब जब हमारे पास नमूना तालिकाएँ हैं, तो हम सम्मिलित करने के लिए संग्रहीत कार्यविधि बनाना शुरू कर सकते हैं।
उपयोगकर्ता परिभाषित तालिका प्रकार बनाएं:
इस संग्रहीत कार्यविधि के लिए, हमें तीन उपयोगकर्ता परिभाषित तालिका प्रकारों का उपयोग करने की आवश्यकता है:
आधार तालिका के लिए एक,
संबंधित तालिका के लिए एक,
और एक अस्थायी आईडी को मैप करने के लिए डेटाबेस-असाइन की गई आईडी पर।
CREATE TYPE udt_base As Table
(
base_id int,
base_temp_id int, -- NOTE: when populating the table valued parameters, this column holds the id used to connect the base and related tables.
base_data int
);
CREATE TYPE udt_related As Table
(
related_base_id int,
related_data int
);
CREATE TYPE udt_idMap as table
(
temp_id int,
id int
)
GO
संग्रहीत कार्यविधि बनाएं:
अब जब हमारे पास उपयोगकर्ता परिभाषित प्रकार हैं, तो हम उनका उपयोग करने के लिए संग्रहीत कार्यविधि बना सकते हैं।
CREATE PROCEDURE stp_InsertMultipleRecordsToMultipleTables
(
@base as dbo.udt_base readonly,
@related as dbo.udt_related readonly
)
AS
DECLARE @idMap as dbo.udt_idMap
MERGE INTO tblBase USING @base AS temp ON 1 = 0 -- Always not matched
WHEN NOT MATCHED THEN
INSERT (base_data)
VALUES (temp.base_data)
OUTPUT temp.base_temp_id, inserted.base_id -- Here we use the base_temp_id to map to the correct id
INTO @idMap (temp_id, id);
INSERT INTO tblRelated(related_base_id, related_data)
SELECT id, related_data
FROM @related r
INNER JOIN @idMap m ON(r.related_base_id = m.temp_id) -- here we use the map to insert the related records with the correct base ids
GO
परीक्षण:
आधार तालिका में 10 रिकॉर्ड और संबंधित तालिका में 1000 रिकॉर्ड पर परीक्षण किया गया, 1 सेकंड से कम समय में निष्पादित किया गया।
यहां परीक्षण के लिए स्क्रिप्ट है:
