Question

I have the following requirement/business rule:
Galaxys
delete * from Galaxys
'append from ADE data - qryGetGalaModel
INSERT INTO tbl Galaxys ( [ID Number], [ID Status], [ Type], [ID Completed], [MK Link ID], [MODEL Link ID], [ID Main Vendor] )

The request is to populate the above in sql database using sql query langauage.
Can someone help please

Answer 1

It looks like you have all the pieces there. Try the update like this:
UPDATE tblRadioDeinstalls
SET tblRadioDeinstalls.[ML number] = [ML_NUMBER],
tblRadioDeinstalls.[Link Status] = [LINK_STATUS]
FROM tblRadioDeinstalls
INNER JOIN tempMLNumber ON tblRadioDeinstalls.[TNE Number] =
tempMLNumber.[TNE Number] ;

You can use aliases in update statements, this makes it easier to read. Look at the test code below.
DECLARE #tableA TABLE
(
id INT
,MyData VARCHAR(20)
);
INSERT INTO #tableA VALUES (0,'First Element'), (1,'Second Element'), (2, 'Fourth Element')
SELECT * FROM #tableA
UPDATE A
SET a.MyData = 'Third Element'
FROM #tableA AS A
WHERE a.id = 2;
SELECT * FROM #tableA
As you notice instead of UPDATE #tableA AS A I just did UPDATE A and defined A in FROM clause. In UPDATE statement SET always follows UPDATE than the rest of information.
