如何在触发器中正确使用sp_send_dbmail？

Question

我在名为Project的表上创建了一个触发器，查询成功编译但是当我向表中插入数据时，我得到一个错误说明：

Msg 14636, Level 16, State 1, Procedure sp_send_dbmail, Line 112 [Batch Start Line 139]
No global profile is configured. Specify a profile name in the @profile_name parameter.

以及：

Msg 3930, Level 16, State 1, Procedure sp_send_dbmail, Line 64 [Batch Start Line 139]
The current transaction cannot be committed and cannot support operations that write to the log file. Roll back the transaction.

我对sp_send_dbmail程序并不完全熟悉，但我试图在触发触发器时将其发送到xxxxx@gmail.com。
