Thread: Wildcard queries via PHP4

Wildcard queries via PHP4

Hi,

I am trying to find the syntax to pass a wildcard query through to postgres.
Basically I just want to use the user input as a substring of the actual query to postgres.
It can even be simpler, I realy only need the wildcard at end of the input string

i.e. user inputs Smith in form, I want to pick up Smith & Smithsonian.

Right now I have:

if ( strlen($NAME) >0):
        $NAME = addslashes($NAME);
        $NAME = strtolower($NAME);   /
        $NAME = ucfirst($NAME);   //translation final to Upper 1st letter rest lower as per db format.

$conn = pg_Connect("dbname=damn_db port=5432");
if(!$conn) { echo "Error in connecting to DB\n"; exit;  }
        $result = pg_Exec($conn, "SELECT * FROM table2 WHERE surname = '$NAME' ");
For whatever reason the *~ matching does not work in PHP4 (ie surname *~ )
(or more precisely I can't get it to work)

Any suggestions?

Many thanks.

Hey,

try LIKE..

so..
$query = "SELECT * FROM table2 WHERE surname LIKE '%$name%'";

the % before matches anything before $name (so goldsmith would match), %
after matches anything after $name (so smithsonian matches)..

Check out http://www.postgresql.org/docs/aw_pgsql_book/node51.html for more
info..

HTH

You could try LIKE and %, but I think it is ~* and not *~

Use LIKE, as others have mentioned.  The reason the wildcard doesn't work is
because it isn't supposed to.  No SQL should use it.

This works for me on 7.1 beta 6; php-4.0.4pl1

$sql="SELECT *
 FROM customer
 WHERE $look_in ~*'$text' AND
  mbewbe='$mbewbe' AND
  c_state $query_location
 ORDER BY company_name;";

As far as I know "LIKE" is case sensitive, where as ~* is regular
expression matching and is case insensitive.

yes the easiest way is     select * from table where LIKE '%$NAME%' for case
sensitive search
or        select * from table where ILIKE '%$NAME%'    if the you want to do
a case insensitive search
much, much, much faster than regular expression
