Hi all,

I have a perl CGI form like thus:

X | Call No  | Call No textfield
X | Problem  | Problem textfield

The X's represent checkboxes.

In the backend, I have two arrays:

@fields: checked fields
@entries: text fields with entries.

my code for generating the SQL is below. My problem
occurs when one enters text into more than one text
field. For example, say I check "Call No" and "Problem"
and enter "111" and "seating" into their respective
text fields. The SQL becomes:

SELECT call_no, problem FROM HELP WHERE 
  ( call_no LIKE 111 problem LIKE seating )  

There needs to be an "AND" in the WHERE clause. The SQL
should read:

SELECT call_no, problem FROM HELP WHERE 
  ( call_no LIKE 111 AND problem LIKE seating )  


I'll be stuffed if I know how to do it.

Can the monks help me???

Thanks,

    Stacy.

  $nfields = @fields;
  
  foreach $i (@entries) {
    if ($i ne '') {
      push @full_entries, $i;
    }
  }
    
  $sql = sprintf "SELECT %s FROM HELP WHERE (", join(", ", @fields);
  
  for ($j = 0; $j < $nfields; $j++) {
    if ($full_entries[$j] ne '') {
      $sql .= sprintf " %s LIKE %s ", $fields[$j], $full_entries[$j];
    }
  }
  
  $sql .= ")";
