Question

I wrote a very simple Perl script that contains the following line.

my $q_it = $dbh->prepare('SELECT customdata.Field_ID,
  customdata.Record_ID,
  customdata.StringValue
  FROM customdata
  WHERE customdata.Field_ID='\'10012'\' && (StringValue LIKE '\'1%'\' OR StringValue LIKE   '\'2%'\' OR StringValue LIKE '\'9%'\');
  ');

in which customdata is a table.

However, I always got syntax error complaining about the “WHERER” clause:

Backslash found where operator expected at /home/wblocaladmin/Robert_2.pl line 18, near "'10012'\"

Since it is a quote inside quote statement, so I tried escaping the single quote like one above. Could any body help me spot where I went wrong?

Thanks!

Why you don’t just use double quotes to enclose the string ?

my $q_it = $dbh->prepare("SELECT customdata.Field_ID,
  customdata.Record_ID,
  customdata.StringValue
  FROM customdata
  WHERE customdata.Field_ID='10012' && (StringValue LIKE '1%' OR StringValue LIKE   '2%' OR StringValue LIKE '9%');
  ");
