Description:

I'm using placeholders (in DBI/MySQL) on a set of INSERT statements;
however, when I try to fill a "?" placeholder with the value of NOW(), I just get the plain string "NOW()" in my data. Is there any way to tell the DBI/MySQL that the NOW() is supposed to be a current time function and not a plain string?

Answer: Placeholders and NOW()

yes:

sub NOW { # Return current time in whatever format it # Needs to be in } $sth->execute(NOW());
But I suspect NOW() is a function in your particular database, in which case you wouldn't use a placeholder, and you would just put a literal NOW() in your SQL statement.

Example:

my $sth = $dbh->prepare(q{ INSERT INTO t ( foo, bar, time ) VALUES (?, ?, NOW() ) }); $sth->execute($foo, $bar);
