Comment dois-je appeler une procédure stockée Oracle à partir d'un script VBA Excel?

Ou vous pouvez utiliser un gestionnaire de connexions. Pas sûr de savoir si je peux télécharger .bas de fichiers ou tous les fichiers de sorte que vous pouvez télécharger les connexions config .fichier bas de moi; utilisez simplement le Fichier d'Importation d'action de la VBE pour importer le fichier téléchargé et copiez le contenu de WorkingExample2 à un nouveau module, puis entrez votre requête entre guillemets de la sRS.

Ou copiez et collez le code suivant dans un nouveau Module. J'ai fourni beaucoup d'informations d'utilisation au début [veuillez donc lire] mais la base est tout simplement le programme d'installation une fois le fichier, puis vous n'avez pas besoin de reconfigurer pour une utilisation future; utilisation ConnectionTest pour vérifier qu'une connexion stable est faite, le cas échéant, il est de débogage.imprimer true else false; utilisation WorkingExample1 uniquement avec SQL Server ou Oracle, il suffit envoie une requête de test et renvoie les résultats.
Comme mentionné ci-dessus, l'utilisation WorkingExample2, l'utiliser pour gérer l'ensemble de vos connexions les seules choses que vous auriez besoin de modifier l'emplacement de la CopyFromRecordSet et la chaîne de requête:

'### General Usage Notes ###
'This file contains all required variables to handle connections to Oracle DB, MS SQL Server & MS Access
'using the default installed Windows drivers; it shall auto-differentiate between 32/64 bit systems to
'ensure that the correct driver is used and for Oracle, neither a tnsnames.ora nor an Oracle client is required
'to be installed.
'Other databases can be accessed, though third-party ODBC / OLE DB drivers must be obtained and installed; should
'you be using another provider, you shall need to update the ServerProvider Case Statment in all ServerConnectionString
'modules; always ensure that you inlcude a call to Connection_Close to ensure that you close off the connection
'after use.
'Initial setup requires you to setup only that which is relevant to your db setup:
'*** Typical Oracle Setup ***
'Servers <Function CnServer>, Databases <Function AppDB>, DBSchema, sSQLUser and sSQLPass
'*** Typical SQL Server Setup ***
'Servers <Function CnServer>, Database <MSSDatabase>, Windows Auth: sTrusted = "yes", SQL Auth: sSQLUser & sSQLPass
'*** MS Access ***
'Access just requires the MDBPath <full path and filename> and file type (*.mdb) or (*.accdb) as the file is
'a single db
'Dynamic Server Selection (DSS) - use these variables to over-ride your setup defaults for one time connections
'to other servers /db's / providers, a typical example would be to default the config file to Oracle but require
'one-time access to SQL Server.
'*** DSS Setup ***
'Only those variables that match your server config are required, simply place the variables in your sub;
'unless you have a reason to keep the values, place a call to ClearDSS at the end of your sub
'Also included is a file-open handler for use with data files (txt/csv/xls/xlsx etc) usage is simply based on
'either optionally passing the full path and filename on the function call or if no passed values shall create from the
'GetOpenFileName control
'Additional features include a connection test which simply checks your connection returning True when a
'stable connection is made; a Query Test (WorkingExample2)returning a correctly parsed query if a connection
'is made and a demo of passing a stored proc (WorkingExample1).
'*** You can use the sub <WorkingExample2> in all of your connections, just copy and paste into your modules ***
'+++ Finally: Usage requires the Microsoft Activex Data Objects Library 2.8 to be set in Tools > References...
'This has been tested with all versions of Excel from 2003 onwards both 32 & 64 bit versions with all versions of
'MS Windows from XP onwards both x86 and x64
