I've written this example script to illustrate what I'm attempting to do:

#my @col = ("machine","runas");
#my @val = ("bar","faa");
my $col = "machine";
my $val = "bar";
my $dbName = "fooDB.db";

#Create DB connection
my $dbh = DBI->connect(          # connect to your database, create if
    "dbi:SQLite:dbname=$dbName", # DSN: dbi, driver, database file
    "",                          # no user
    "",                          # no password
   { RaiseError => 1 },         # complain if something goes wrong
) or die $DBI::errstr;

#Create Table
$dbh->do('create table schedules
        (schedId INTEGER PRIMARY KEY,
        schedName TEXT,
        machine TEXT,
        runas TEXT,
        owner TEXT)' );

#Insert 1 row
my $sth = $dbh->prepare_cached("INSERT into schedules (schedName) valu
+es ('foo')")
        or die "Couldn't prepare statement: " . $dbh->errstr;
$sth->execute()
        or die "Couldn't execute statement: " . $sth->errstr;

#Get row ID
my $rowId = $dbh->func('last_insert_rowid');

#Do an update with mutiple placeholders
my $sth1 = $dbh->prepare_cached("UPDATE schedules SET ? = ? WHERE sche
+dId = ?")
        or die "Couldn't prepare statement: " . $dbh->errstr;

#Try with bind_param_array
#$sth1->bind_param_array(1, @col);
#$sth1->bind_param_array(2, @val);
#$sth1->bind_param_array(3, $rowId); # scalar will be reused for each 
+row
#$sth1->execute_array()

$sth1->execute($col,$val,$rowId)
        or die "Couldn't execute statement: " . $sth->errstr;

No matter how I use this, with bind_param_array or with straight scalars, I get the same error:

DBD::SQLite::db prepare_cached failed: near "?": syntax error at ./foo
+.pl line 37.
DBD::SQLite::db prepare_cached failed: near "?": syntax error at ./foo
+.pl line 37.
