异地托管SQL Server无服务器权限，如何运行指定SQL及相关疑问

Let's break down each of your questions clearly:

1. Do I need SQL Server access permissions to run this statement? #

Yes, you do need specific permissions to execute this query. The sys.triggers catalog view requires the VIEW DEFINITION permission on the database, or membership in one of these roles:

• db_owner
• db_ddladmin
• db_datareader

Without these permissions, you'll receive an error stating you don't have access to the system view.

2. Is the SQL statement reasonable? #

Absolutely. This is a valid, read-only query that retrieves metadata about triggers in your iMIS database. It pulls:

• The name of the table each trigger is attached to (TableName)
• The trigger's name (TriggerName)
• When the trigger was created (CreationDate)
• When it was last modified (ModifyDate)

It uses standard SQL Server system views, so it's a safe and common way to audit existing triggers. There's no risk of modifying data or breaking anything by running this.

3. Will executing this statement improve database running speed? #

No, running this query will not directly improve database performance. This is purely an informational query—it only reads metadata about triggers, it doesn't make any changes to the database, indexes, or trigger logic.

If your goal is to boost server response speed, this query might be a starting point to identify problematic triggers (like ones with inefficient logic, or unnecessary triggers that run on every write operation). But you'd need to take additional actions (like optimizing trigger code, disabling unused triggers, or adding indexes to support trigger logic) to actually see performance gains.
