Question

Sorry if the question is too basic, I’m teaching myself TSQL and I don’t know how the following is done:

I have this query:

SELECT table1.name, table2.city AS city, table2.province
FROM table1 LEFT OUTER JOIN table2
ON table1.id = table2.id
WHERE table1.name NOT LIKE 'test'
ORDER BY city DESC 

And I want to add to it this other one:

SELECT table3.country 
FROM table3 LEFT JOIN table2 
ON table3.id = table2.id
WHERE table2.city = city

So I can have this result:

name — city — province — country

How can I do so?

Thanks a lot!

Answer 1

Simply use two joins in one SQL statement:

SELECT table1.name, table2.city AS city, table2.province, table3.country
FROM table1
LEFT OUTER JOIN table2 ON table1.id = table2.id
LEFT OUTER JOIN table3 ON table3.id = table2.countryid
WHERE table1.name NOT LIKE 'test' and table2.city = 'Cityname'
ORDER BY city DESC 

(Sorry guys, I didn’t have time to check it, thanks for the comment. Code is revised.)
