Perl / CGI / Mysql
Perl / CGI / Mysql
(OP)
Hi
I am new to Perl and CGI programming (OK, week off work and I have been playing). I have a minor problem using Mysql. I am having no problems pulling records from a database, but I cannot see how to pull the results of an SQL function. For example I want to know the latest date that certain records have been updated and have coded a "Select max(fred_date) from db_fred where fred_name = 'Smith'"
Presumably I need to return this into a result set. Up to this point I have used the syntax $ref->{'fred_name'} to retrieve the value of a field. What do I use for the result of a function?
Thanks alot
Keith

while ($var1,$var2,$var3...) = $sth->fethrow_array)
If you prefer the hash, you could also assigning an alias name to the function results. Check the mysql docs.
