插入比较值并发送邮件的触发器

Question

目前，我已经测试了这个触发器，它会在每次插入表格时向我发送一封电子邮件。

CREATE TRIGGER dr_insert ON data_record 
    AFTER INSERT 
AS 

EXEC msdb.dbo.sp_send_dbmail
        @profile_name = 'TEST',
        @recipients = 'azfarkashif@hotmail.com',
        @body = 'New data uploaded',
        @subject = 'TriggerTest';

GO

如何自定义此触发器，以便它考虑新插入的行中的列，比较它（例如 temp > 70 || temp

Answer 1

您需要使用 inserted 表。在 SQL 中也称为魔术表。

CREATE TRIGGER dr_insert ON data_record 
    AFTER INSERT 
AS 
BEGIN
    DECLARE @temp INT

    SET @temp = (SELECT column FROM inserted)

    IF @temp > 70 || @temp <40
        BEGIN
            EXEC msdb.dbo.sp_send_dbmail
            @profile_name = 'TEST',
            @recipients = 'azfarkashif@hotmail.com',
            @body = 'New data uploaded',
            @subject = 'TriggerTest';
        END
END
GO
