由 混江龙づ霸主 提交于 2021-02-08 05:37:41
问题 I tried many event types but could not achieve logging for Linked server. I could figure out events for all other databases but no luck with linked server.

The following DDL creates this extended event and adjusting the options (i.e. FILENAME , MAX

Create Trigger to log SQL that affected table?

由 空扰寡人 提交于 2019-12-17 03:19:09

Details: MS SQL
