    Initialise une procédure stockée MS SQL Server locale ou distante.

    Liste de paramètres

    sp_name

    Le nom d'une procédure stocké, comme ownew.sp_name ou otherdb.owner.sp_name.

    link_identifier

    Un identifiant de lien MS SQL, retourné par la fonction mssql_connect().

    Valeurs de retour

    Retourne un identifiant de ressource de requête, à utiliser lors des appels aux fonctions mssql_bind() et mssql_execute(), ou FALSE si une erreur survient.

    Exemples

    Exemple #1 Exemple avec mssql_init()

    <?php
    // Connexion à MSSQL et sélection de la base de données
    $link = mssql_connect('KALLESPC\SQLEXPRESS', 'sa', 'phpfi');
    mssql_select_db('php', $link);

    // Création d'une nouvelle commande
    $stmt = mssql_init('StatementTest', $link);

    // Liaisons des valeurs ici

    // Une fois que les valerus sont liées, nous pouvons exécuter
    // notre commande avec mssql_execute:
    mssql_execute($stmt);

    // Et nous pouvons tout libérer ainsi : 
    mssql_free_statement($stmt);

    If you are performing a stored procedure inside a loop, it is a good idea to unset the variable that mssql_init returns so that you do NOT bind multiple values to the same stored procedure:

    foreach($input  as $sid=>$value) {
      $stmt = mssql_init("sp_doSomething");
      mssql_bind($stmt, "@sid", $sid, SQLINT4, false);
      mssql_bind($stmt, "@value", $value, SQLINT4, false);
      $result = mssql_execute($stmt);
      unset($stmt);  // <---VERY important
    }

    Even doing the mssql_init outside the loop does not help because of the multiple binds happening inside the loop.

    Failing to do the above generates "Access Violations...memory cannot be 'written'" errors on the server.  My hypothesis is that the error is generated when you try to bind to a stored procedure after it has already been executed.  You have been warned.

    this function was created to support 
    OUTPUT parameters and return values with
    MSSQL stored procedures. Before this,
    you could use T-SQL statement EXECUTE
    and mssql_query to execute a stored
    procedure, and it was fine as long as
    you don't need to retrieve OUTPUT or
    RETVAL values.


    Now you can use this set of functions to execute and retrieve these values:
    mssql_init
    mssql_bind
    mssql_execute

    Parameters:
    - sp_name : stored procedure name. It passes this string to a native DB-lib call, so I guess it supports all kinds of schemas (like "ownew.sp_name" or "otherdb.owner.sp_name")

    - connection id: a connection resource
    obtained with mssql_connect or similar.
    If not provided, it will proceed just
    like other similar mssql_* functions:
    uses a default open connection or
    creates a new one.

    Return value: a resource id, called
    "statement", used in subsequent calls to
    mssql_bind and mssql_execute.

    Note that many of the native MSSQL data types are directly supported, but I
    think that some others must be converted
    by other means (from varchar values for
    example). These unsupported types are:

    SQLMONEY4,SQLMONEY,SQLBIT,SQLDATETIM4,
    SQLDATETIME, SQLDECIMAL, SQLNUMERIC,
    SQLVARBINARY, SQLBINARY,SQLIMAGE
