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：

消息468，级别16，状态9，第4行

无法在等于操作的情况下解决Danish_Norwegian_CI_AS和SQL_Latin1_General_CP1_CI_AS之间的排序规则冲突。

我尝试将此附加到查询中，但它仍然返回相同的错误：

COLLATE SQL_Latin1_General_CP1_CI_AS ASC

我该如何解决这个问题？

Answer 1

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

e.g。（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

Answer 2

创建表格#exclude时，您需要将COLLATE DATABASE_DEFAULT添加到任何文本字段 - 如下所示：

CREATE TABLE #exclude(name VARCHAR(256) COLLATE DATABASE_DEFAULT NULL)
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

无法解决临时表和sys.objects之间的排序规则冲突
