sql截断/填充字符串

Question

我需要这样的东西

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 )

我必须使用空格来填充字符串。我怎么能做到这一点？

假设 SQL Server，SQL 数据类型 char 用字符串填充，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...
