Perbarui tabel menggunakan nilai dari tabel lain di SQL Server

Saya memiliki 2 tabel di database saya.

Tabel 1

-------------------------------------------------------------------------
| name | family | phone | email | gender | phone2 | address | birthdate |
-------------------------------------------------------------------------

Meja 2

-----------------------------------------
| gender | address | phone | birthdate |
-----------------------------------------

pada tabel # 1 kolom alamat dan phone2 kosong dan kolom gender dan tanggal lahir sama dengan tabel # 2.

Bagaimana saya bisa membaca data dari tabel # 2 dan memperbarui alamat dan phone2 dalam tabel # 1 dengan nilai dari tabel # 2 alamat dan kolom telepon ketika jenis kelamin dan tanggal lahir sama di setiap baris?

misalnya: ini adalah beberapa data dalam Tabel # 1

-------------------------------------------------------------------------
| name | family | phone | email | gender | phone2 | address | birthdate |
-------------------------------------------------------------------------
| john | doe    | 12345| t@t.com| Male  |         |         | 1980-01-01|
-------------------------------------------------------------------------
| mike | clark  | 65432| x@y.com| Male  |         |         | 1990-01-01|
-------------------------------------------------------------------------
| Sara | King   | 875465| a@b.com|Female|         |         | 1970-01-01|
-------------------------------------------------------------------------

dan berikut adalah beberapa data dalam tabel # 2

-----------------------------------------
| gender | address | phone | birthdate  |
-----------------------------------------
| Male   | 1704test|0457852|1980-01-01  |
-----------------------------------------
| Female | 1705abcs|0986532|1970-01-01  |
-----------------------------------------
| Male   | 1602cyzd|0326589|1990-01-01  |
-----------------------------------------

Saya ingin memperbarui tabel # 1 dengan data dari tabel # 2 dan memeriksa jenis kelamin dan tanggal lahir dan membuat tabel # 1 seperti

-------------------------------------------------------------------------
| name | family | phone | email | gender | phone2 | address | birthdate |
-------------------------------------------------------------------------
| john | doe    | 12345| t@t.com| Male   |0457852 |1704test | 1980-01-01|
-------------------------------------------------------------------------
| mike | clark  | 65432| x@y.com| Male   |0326589  |1602cyzd| 1990-01-01|
-------------------------------------------------------------------------
| Sara | King   | 875465| a@b.com|Female |0986532  |1705abcs| 1970-01-01|
-------------------------------------------------------------------------

Bagaimana saya bisa melakukan ini?

Ada beberapa cara untuk mencapai hasil yang Anda inginkan.

Metode yang tidak ditentukan

(dalam hal banyak baris dalam tabel 2 cocok satu dalam tabel 1)

UPDATE T1
SET    address = T2.address,
       phone2 = T2.phone
FROM   #Table1 T1
       JOIN #Table2 T2
         ON T1.gender = T2.gender
            AND T1.birthdate = T2.birthdate

Atau bentuk yang sedikit lebih ringkas

UPDATE #Table1
SET    address = #Table2.address,
       phone2 = #Table2.phone
FROM   #Table2
WHERE  #Table2.gender = #Table1.gender
       AND #Table2.birthdate = #Table1.birthdate 

Atau dengan CTE

WITH CTE
     AS (SELECT T1.address AS tgt_address,
                T1.phone2  AS tgt_phone,
                T2.address AS source_address,
                T2.phone   AS source_phone
         FROM   #Table1 T1
                INNER JOIN #Table2 T2
                  ON T1.gender = T2.gender
                     AND T1.birthdate = T2.birthdate)
UPDATE CTE
SET    tgt_address = source_address,
       tgt_phone = source_phone 

Metode deterministik

MERGE akan melempar kesalahan daripada menerima hasil non deterministik

MERGE #Table1 T1
USING #Table2 T2
ON T1.gender = T2.gender
   AND T1.birthdate = T2.birthdate
WHEN MATCHED THEN
  UPDATE SET address = T2.address,
             phone2 = T2.phone; 

Atau Anda dapat memilih catatan tertentu jika ada lebih dari satu pertandingan

Dengan APPLY

UPDATE T1
SET    address = T2.address,
       phone2 = T2.phone
FROM   #Table1 T1
       CROSS APPLY (SELECT TOP 1 *
                    FROM   #Table2 T2
                    WHERE  T1.gender = T2.gender
                           AND T1.birthdate = T2.birthdate
                    ORDER  BY T2.PrimaryKey) T2 

.. Atau CTE

WITH T2
     AS (SELECT *,
                ROW_NUMBER() OVER (PARTITION BY gender, birthdate ORDER BY primarykey) AS RN
         FROM   #Table2)
UPDATE T1
SET    address = T2.address,
       phone2 = T2.phone
FROM   #Table1 T1
       JOIN T2
         ON T1.gender = T2.gender
            AND T1.birthdate = T2.birthdate
            AND T2.RN = 1;

UPDATE TS
SET TS.TaskFullAddress = L.FullAddress
FROM [dbo].[TaskOrders]   TS
INNER JOIN Locations L
ON  TS.ClientId  = L.ClientId;
