如果插入的记录包含文本，则-TSQL

Question

Pseudo code: If the newly inserted record contains the text 'Important' then send db_mail

Here is the trigger:

SET NOCOUNT ON;
        IF (columnName.INSERTED = 'Important') 
            BEGIN       
                "Send db_mail query here"
            END

Error I am getting:

The multi-part identifier "columnName.INSERTED" could not be bound.

You need to query pseudotable INSERTED :

IF (columnName.INSERTED = 'Important') 


IF EXISTS (SELECT *
          FROM INSERTED
          WHERE columnName = 'Important')
....

Please not that SQL Server trigger is statement based so you will need some kind of CURSOR to handle multiple rows. Also sending mails directly from trigger may affect performance.
