SQL截断/垫串

Question

我需要这样的事情，

SELECT CLIENT_AHCCCS_ID + CLIENT_FIRST_NAME + CLIENT_LAST_NAME + replace(convert(datetime, DATE_OF_BIRTH, 1), '/', '') 
FROM tblCLIENT 
WHERE CLIENT_AHCCCS_ID IS NOT NULL AND CLIENT_AHCCCS_ID LIKE 'A%' 

但必须确保

CLIENT_AHCCCS_ID  (9 character) 
Member Last Name  (25 character) 
First Name   (25 character) 

我必须用空格填充的字符串。我怎么能做到这一点？

假设的SQL Server，SQL数据类型字符垫用字符串，所以你总是可以转换为：

SELECT 
    CONVERT(char(9), CLIENT_AHCCCS_ID) + 
    CONVERT(char(25), CLIENT_FIRST_NAME) + 
    CONVERT(char(25), CLIENT_LAST_NAME) + 
    replace...
