有没有办法忽略和接受整理？

Question

I have a problem with a SQL request :

SELECT  CLCLEUNIK, NOM, VILLE, CODEP 
FROM CLIENT 
WHERE NOM LIKE :nom COLLATE French_CI_AI

In my case, I use the collate because a user can search "rhone" and it will find "rhône". But my problem is that now when someone searches "Rhône", the request doesn't find any match in my database.

Edit : this is the creation of the base :

SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[CLIENT](


    [NOM] [varchar](50) NULL,
    [ADRESSE] [text] NULL,
    [CODEP] [varchar](5) NULL,
    [VILLE] [varchar](40) NULL,
    [TYPECLI] [int] NULL,
    [TEL] [varchar](20) NULL,



) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO

This is the php code :

 public function searchCli(Request $request){
        require __DIR__.DIRECTORY_SEPARATOR."..".DIRECTORY_SEPARATOR."Entity".DIRECTORY_SEPARATOR."sqlconnect.php";


          $nom = $request->request->has("nom") ? $request->request->get("nom") : "";
          $nom = str_replace(" ", "%", $nom);


          $req ="SELECT  CLCLEUNIK, NOM, VILLE, CODEP FROM CLIENT WHERE NOM LIKE :nom COLLATE French_100_CI_AI";
          $prepare = $pdo->prepare($req);
          $prepare->execute(
            [
              "nom" => "%{$nom}%"
            ]
          );



          $clientsrecherche = $prepare->fetchAll(PDO::FETCH_OBJ);

          foreach($clientsrecherche as $key => $objet){
            foreach($objet as $key2 => $obj){
              $obj=utf8_encode($obj);
              $response[$key][$key2] = $obj;
            };
          }                     
            return new JsonResponse([ "response" => $response]);
       }

It's all I can have to help

Answer 1

For more description:

collation properties:

CI specifies case-insensitive (case insensitive comparisons so 'ABC' would equal 'abc')

CS specifies case-sensitive

AS specifies accent-sensitive (accent sensitive, so 'ü' does not equal 'u')

AI specifies accent-insensitive

You can try French_100_CI_AI instead of French_CI_AI
