我们每隔几个月就会遇到一个问题,因为quoted_Identifier问题会突然导致作业或程序失败。 proc或even表中引用的标识符将从1更改为0,我们不会在该记录上看到最近修改的日期。我们不确定这是如何发生的,因为它是如此零星,我无法复制或轻松追踪它。关于为什么会发生这种情况或我能做些什么来找出的任何想法。到目前为止,我已经做了很多没有运气的研究。

您可以创建由CREATE / ALTER PROCEDURE事件激活的DDL触发器。在此触发器中,您可以使用EVENTDATE函数来获取有关SQL语句执行的信息,包括ANSI_NULLS和QUOTED_IDENTIFIER设置。
例如,您可以使用Adventure Works OLTP database中的ddlDatabaseTriggerLog
ddl触发器,从当前数据库中插入[dbo].[DatabaseLog]
所有ddl更改。
DDL触发器:
CREATE TRIGGER [ddlDatabaseTriggerLog] ON DATABASE
FOR DDL_DATABASE_LEVEL_EVENTS AS
BEGIN
SET NOCOUNT ON;
SET ANSI_WARNINGS ON;
DECLARE @data XML;
DECLARE @schema sysname;
DECLARE @object sysname;
DECLARE @eventType sysname;
SET @data = EVENTDATA();
SET @eventType = @data.value('(/EVENT_INSTANCE/EventType)[1]', 'sysname');
SET @schema = @data.value('(/EVENT_INSTANCE/SchemaName)[1]', 'sysname');
SET @object = @data.value('(/EVENT_INSTANCE/ObjectName)[1]', 'sysname')
IF @object IS NOT NULL
PRINT ' ' + @eventType + ' - ' + @schema + '.' + @object;
ELSE
PRINT ' ' + @eventType + ' - ' + @schema;
IF @eventType IS NULL
PRINT CONVERT(nvarchar(max), @data);
INSERT [dbo].[DatabaseLog]
(
[PostTime],
[DatabaseUser],
[Event],
[Schema],
[Object],
[TSQL],
[XmlEvent]
)
VALUES
(
GETDATE(),
CONVERT(sysname, CURRENT_USER),
@eventType,
CONVERT(sysname, @schema),
CONVERT(sysname, @object),
@data.value('(/EVENT_INSTANCE/TSQLCommand)[1]', 'nvarchar(max)'),
@data
);
END;

这些脚本很有帮助,我将来会使用它们。我弄清楚问题是什么。存储过程将quoted_identifier设置为0,并且它已经存在至少一年。但是,有人在存储过程正在使用的表上创建了筛选索引。他们没有意识到过滤后的索引需要将quoted_identifier设置为1。
