I have an update statement which I am parsing with SQL::Parser

uPdate scott.emp 
set ename='SCT%',emp_date=TO_DATE('04/16/2011 00:00:00', 'MM/DD/YYYY H
+H24:MI:SS'),empno='15645' 
WHERE dept=20 and ename IN(select ename from emp where empno='1111');

But since TO_DATE function cannot be parsed with SQL::Parser hence it throws error:

Incomplete SET clause! at ./post_audit.pl line 173
Incomplete SET clause! at ./post_audit.pl line 173

How do I catch such errors? Does eval do the trick? Did not find proper documentation for the same. Code to parse the SQL statements:

   +12  use SQL::Parser;

   +34  my $statement = "uPdate scott.emp set ename='SCT%',emp_date=TO
+_DATE('04/16/2011 00:00:00', 'MM/DD/YYYY HH24:MI:SS'),empno='15645' W
+HERE dept=20 and ename IN(select ename from emp where empno='1111')";

  +172      my $parser = SQL::Parser->new('AnyData', {RaiseError=>1} )
+;
  +173      $parser->parse($statement);

Error is thrown at line 173 while parsing the statement. Initially I thought the problem comes from here inside Parser.pm

sub SET_CLAUSE_LIST
{
    my ( $self, $set_string ) = @_;
    my @sets = split( /,/, $set_string );
    my ( @cols, @vals );
    for my $set (@sets)
    {
        my ( $col, $val ) = split( m/ = /, $set );
        return $self->do_err('Incomplete SET clause!') unless ( define
+d($col) && defined($val) );
        push( @cols, $col );
        push( @vals, $val );
    }
    return undef
      unless ( $self->{struct}->{column_defs} = $self->ROW_VALUE_LIST(
+ join ',', @cols ) );
    return undef unless ( $self->LITERAL_LIST( join ',', @vals ) );
    return 1;
}

But the problem is not with regex. The problem is with TO_DATE function only. My question is not to fix the given parsed SQL to the Parser, but how to catch such errors and probably print a statement. I could'nt find proper documentation for this.

Thanks!!
