Re: Best way to call DBI query

I believe this is because shift() is diffrent than shift. Calling shift() i believe forces shift to be called with no arguments, rather than with @_ as is done when called without parens.

If you are right, why does the following work correctly: `sub AnySub { my @list = @{ shift() }; # automatic dereferencing list ...` [download] Best regards, perl -le "s==F=e=>y~\martinF~stronat~=>s~[^\w]~~g=>chop,print"	[reply] [d/l]

In that case, i stand (well, sit actually), corrected. Was worth a shot. As a side comment, i assume something is assigning a database handle to the `$self` object, and that `$self` has a `param()` method which returns that value. You probably shoud be checking `defined($dbh)` to make sure the Database connection was successful, and that nothing has gone wrong to this point. from the frivolous to the serious	[reply] [d/l] [select]
