Send email when a value in the table reached a certain number

Question

Hello,
I have a value in a table that when this value is equal or greater than a certain value, I want to send an email to alert. How do I accomplish this? Do I create a trigger? Do I write an o/s korn script and schedule to run continuosly and check for the value to send an email? Thanks.

Hi, i think that the best form is create a trigger on the table, when insert o update the data send the email when the value accomplish the condition.
Look the next code, it is a package that send emails,
CREATE OR REPLACE
PACKAGE oracle_administrator.dbms_mail_server
IS
P_SERVERNAME VARCHAR(50);
P_RCPT VARCHAR(50);
P_FROM VARCHAR(50);
P_TO VARCHAR(50);
P_SUBJECT VARCHAR(50);
P_BODY CLOB;
P_MAIL UTL_SMTP.CONNECTION;
PROCEDURE INIT_SERVER;
PROCEDURE SEND_EMAIL;
PROCEDURE WRITE_DATA(PARAM_DATA IN CLOB);
END;
CREATE OR REPLACE
PACKAGE BODY oracle_administrator.dbms_mail_server
IS
PROCEDURE SEND_EMAIL
AS
BEGIN
UTL_SMTP.CLOSE_DATA(P_MAIL);
UTL_SMTP.QUIT(P_MAIL);
END;
PROCEDURE INIT_SERVER
AS
BEGIN
P_MAIL :=UTL_SMTP.OPEN_CONNECTION(P_SERVERNAME);
UTL_SMTP.HELO(P_MAIL,'hostname');
UTL_SMTP.MAIL(P_MAIL,'dbaoracle');
UTL_SMTP.RCPT(P_MAIL,P_RCPT);
UTL_SMTP.OPEN_DATA(P_MAIL);
UTL_SMTP.WRITE_DATA(P_MAIL,
'FROM: ' ||P_FROM || UTL_TCP.CRLF||
'TO: ' || P_TO || UTL_TCP.CRLF ||
'SUBJECT: ' ||P_SUBJECT || UTL_TCP.CRLF ||
'MIME-VERSION: 1.0' ||CHR(13)|| CHR(10)||'CONTENT-TYPE: TEXT/HTML' || CHR(13)||CHR(10));
END;
PROCEDURE WRITE_DATA(PARAM_DATA IN CLOB)
AS
BEGIN
UTL_SMTP.WRITE_DATA(P_MAIL,PARAM_DATA);
END;
END;
Luck
Have a goof day.
