Thread: Shell Command within function
Is this possible?
I have a script which imports csvlogs into a table, and it would be useful to truncate the log files after import
thanks

In an untrusted pl language, yes, but it's a bad idea because: Mike> I have a script which imports csvlogs into a table, and it would Mike> be useful to truncate the log files after import If you had an error after truncating the file but before committing the transaction, then the imported data would be gone, but the file would be gone too, so you'd have lost it. Things like this need to be handled _after_ commit, not before, so a function is the wrong place for it. -- Andrew (irc:RhodiumToad)
