Re: sysadmin:ph_alert cleanup

Posted By: FRANK

In Response To: Re: sysadmin:ph_alert cleanup (John Miller iii)

Thanks a lot , John!

I would like to do a TRUNCATE ph_alert first before recreating the
function, what do you think? ( because I want to release its occupied
spaces, a great deal of)

Normally I am very reluctant/cautious to do any thing on a table which is
not maintained by me.

Thanks again!
Frank
