Question

Intento generar una consulta que seleccione todo de una tabla de usuario donde cualquier combinación del apellido del primer nombre coincida con un término de búsqueda particular

$select = $select->where(''last_name LIKE ?'', ''%''.$term.''%'')->orWhere(''first_name LIKE ?'', ''%''.$term.''%'')
                        ->orWhere("CONCAT(first_name,'' '', last_name) LIKE ?", ''%''.$term.''%'')
                        ->orWhere("CONCAT(last_name,'' '', first_name) LIKE ?", ''%''.$term.''%'');                           

Hay otra condición que también debe cumplirse y que se especifica en otra cláusula where

$select = $select->where("deleted = 0 AND scholar = 0");

Se genera la siguiente instrucción SQL

SELECT `user`.* FROM `user` WHERE (last_name LIKE ''%frank%'') OR (first_name LIKE ''%frank%'') OR (CONCAT(first_name,'' '', last_name) LIKE ''%frank%'') OR (CONCAT(last_name,'' '', first_name) LIKE ''%frank%'') AND (deleted = 0 AND scholar = 0) ORDER BY `date_created` desc LIMIT 25

Esto no devuelve el resultado deseado ya que obtengo filas donde scholar = 1;

Pensé que la consulta debería ser

SELECT `user`.* FROM `user` WHERE ((last_name LIKE ''%frank%'') OR (first_name LIKE ''%frank%'') OR (CONCAT(first_name,'' '', last_name) LIKE ''%frank%'') OR (CONCAT(last_name,'' '', first_name) LIKE ''%frank%'')) AND  (deleted = 0 AND scholar = 0) ORDER BY `date_created` DESC LIMIT 25

Cuál es la sintaxis correcta para lograr esto utilizando el objeto $ select.

Answer 1

Puede usar quoteInto para preparar sus condiciones y luego usarlas así:

    $first_name_cond = $db->quoteInto(''first_name LIKE ?'', ''%''.$term.''%'');
    $last_name_cond = $db->quoteInto(''last_name LIKE ?'', ''%''.$term.''%'');

    $concat_cond1 = $db->quoteInto("CONCAT(first_name,'' '', last_name) LIKE ?", ''%''.$term.''%'');

    $concat_cond2 = $db->quoteInto("CONCAT(last_name,'' '', first_name) LIKE ?", ''%''.$term.''%'');


    $select = $select->where($first_name_cond.'' OR ''.$last_name_cond.'' OR ''.

             $concat_cond1.'' OR ''.$concat_cond2)->where("deleted = 0 AND scholar = 0");

Answer 2

Supongo que eliminado y erudito son columnas separadas. Entonces, la manera más fácil es simplemente romper:

$select = $select->where("deleted = 0 AND scholar = 0");

en dos declaraciones, como:

$select->where("deleted = ?", 0);
$select->where("scholar = ?", 0);

este cambio debería dar como resultado una cadena sql como:

SELECT `user`.* FROM `user` WHERE (last_name LIKE ''%frank%'')
OR (first_name LIKE ''%frank%'') 
OR (CONCAT(first_name,'' '', last_name) LIKE ''%frank%'') 
OR (CONCAT(last_name,'' '', first_name) LIKE ''%frank%'') 
AND deleted = 0 AND scholar = 0 ORDER BY `date_created` desc LIMIT 25

también elimine el extra $select = . Toda tu selección debería parecerse a algo como:

//first line initializes the select object
//The select object will handle most quoting needs for you

$select = $this->select();

//I like to add expressions this way just to keep things easy to read and easy to edit
//you can string multiple statements together, but I find that harder to edit.

$select->where(''last_name LIKE ?'', ''%''.$term.''%'');
$select->orWhere(''first_name LIKE ?'', ''%''.$term.''%'');
$select->orWhere("CONCAT(first_name,'' '', last_name) LIKE ?", ''%''.$term.''%'');
$select->orWhere("CONCAT(last_name,'' '', first_name) LIKE ?", ''%''.$term.''%'');
$select->where("deleted = ?", 0);
$select->where("scholar = ?", 0);
$select->order(''date_created DESC'');
$select->limit(25);

$user = new Application_Model_DbTable_User();
            // User List

$uname=$_POST[''uname''];

echo $query = $user->select()->where(''firstname LIKE ?'', $uname.''%'')->ORwhere(''lastname LIKE ?'', $_POST[''lname''].''%'')->ORwhere(''emailid LIKE ?'', $_POST[''email''].''%'');

$userlist = $user->fetchAll($query);
