无法解决临时表和sys.objects之间的排序规则冲突

Question

以下T-SQL代码:

CREATE TABLE #exclude(name VARCHAR(256))
INSERT INTO #exclude VALUES('someprefix_someprocedure')

SELECT 'someschema.' + sys.objects.name
FROM sys.objects
  LEFT JOIN #exclude ON sys.objects.name = #exclude.name
WHERE sys.objects.name LIKE 'someprefix_%'
  AND type IN ('FN', 'TR', 'P')
  AND #exclude.name IS NULL
ORDER BY sys.objects.name ASC

返回此错误:

Msg 468,Level 16,State 9,Line 4

无法解决等于操作之间Danish_Norwegian_CI_AS和之间的排序规则冲突SQL_Latin1_General_CP1_CI_AS.

我尝试将此附加到查询,但它仍然返回相同的错误:

COLLATE SQL_Latin1_General_CP1_CI_AS ASC

我怎样才能解决这个问题？

Answer 1

将以下内容添加到 WHERE 或 ON (JOIN) 子句中产生此错误的任何字段： COLLATE DATABASE_DEFAULT。

例如（上面你的问题）

CREATE TABLE #exclude(name VARCHAR(255))
INSERT INTO #exclude VALUES('someprefix_someprocedure')

SELECT 'someschema.' + sys.objects.name
FROM sys.objects
  LEFT JOIN #exclude ON sys.objects.name COLLATE DATABASE_DEFAULT = #exclude.name COLLATE DATABASE_DEFAULT
WHERE sys.objects.name LIKE 'someprefix_%'
  AND type IN ('FN', 'TR', 'P')
  AND #exclude.name IS NULL
ORDER BY sys.objects.name ASC
