    Descripción

    mssql_init ( string $sp_name [, resource $link_identifier ] ) : resource

    Inicializa un stored procedure (procedimiento almacenado) local o remoto.

    Parámetros

    sp_name

    Nombre del stored procedure, como ownew.sp_name o otherdb.owner.sp_name.

    link_identifier

    Un identificador de la conexión MS SQL, devuelto por mssql_connect().

    Valores devueltos

    Devuelve un identificador de recurso llamado "statement", utilizado en subsiguientes llamadas a la función mssql_bind() y mssql_execute(), o FALSE si se producen errores.

    Ejemplos

    Ejemplo #1 Ejemplo de mssql_init()

    <?php
    // Conectar a MSSQL y seleccionar la base de datos
    $link = mssql_connect('KALLESPC\SQLEXPRESS', 'sa', 'phpfi');
    mssql_select_db('php', $link);

    // Crear una nueva sentencia
    $stmt = mssql_init('StatementTest', $link);

    // Vincular valores aquí

    // Una vez que los valores han sido vinculados ejecutamos nuestra sentencia 
    // utilizando mssql_execute:
    mssql_execute($stmt);

    // Y liberamos el recurso del siguiente modo:
    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
