sql-server - 在 CONCAT 中使用逐份打印

Question

我试图连接 2 列，中间有空格，但出现排序错误:

SELECT DISTINCT
    p.PERSON_ID,
    p.ID_NUMBER,
    CONCAT(p.FULLNAMES, CONCAT(' ', p.SURNAME)) AS NAME,
    o.ORG_NAME,
    w.WARD_DESCRIPTION AS WARD,
    ess.DESCRIPTION AS SECTOR

Cannot resolve the collation conflict between "SQL_Latin1_General_CP1_CI_AS" and "Latin1_General_CI_AS" in the concat operation

我的数据库中两个有问题的列的排序规则是:Latin1_General_CI_AS

然后我试图将空格整理到这个排序规则中，但我不知道该怎么做。我的尝试:

CONCAT(p.FULLNAMES, (CONCAT((COLLATE Latin1_General_CI_AS = ' '), p.SURNAME))) AS NAME,

或者什么？

Answer 1

您将 COLLATE 放在每个字段之后，即在最坏的情况下:

SELECT DISTINCT
    CONCAT(p.FULLNAMES COLLATE Latin1_General_CI_AS, 
      (CONCAT(' ' COLLATE Latin1_General_CI_AS, 
          p.SURNAME COLLATE Latin1_General_CI_AS))) AS NAME
FROM Person p
