SQL如何將圓括號添加到輸出數據

Question

對於大學作業，我需要在括號中顯示最後一列輸出數據，如下所示。

我當前的查詢是：

SELECT 
SUBSTRING(FirstName,1,1) AS '', 
'.' AS '', 
LastName AS '', UPPER(Title) AS '' 
FROM employees 
WHERE (Title != 'Sales Representative'); 

該查詢顯示輸出：

B . Brown STOREMAN 
C . Carr  RECEPTIONIST 
D . Dig  DRIVER 

我需要它來顯示：

B . Brown (STOREMAN) 
C . Carr  (RECEPTIONIST) 
D . Dig  (DRIVER) 

Answer 1

你應該能夠做到這一點使用CONCAT功能

SELECT 
SUBSTRING(FirstName,1,1) AS '', 
'.' AS'', 
LastName AS '', CONCAT('(',UPPER(Title),')') AS '' 
FROM employees 
WHERE (Title !='Sales Representative');
