Hi all,
I have a table that includes an auto_increment field.
This is used to build up an audit trail of the passage of a file through my
server. As a file is received from a remote system I create the first entry
for that file in the audit trail table. I build up an sql INSERT command
(I'm
updating the table using Perl and DBI) using information about the file -
it's name, the IP address of the sending machine and so on.
What I want to do is immediately retrieve or otherwise have returned to my
perl program the value of the auto increment field for the newly added row.
Either user $dbh->{mysql_insertid} after issuing the insert, or
issue a SELECT LAST_INSERT_ID() query and retrieve the result.
It is possible (indeed likely) that multiple processes might be updating the
table at the same time.
Doesn't matter. That's not an issue.
Thanks
Bob
