Seguendo i diversi tutorial presenti sul sito ho imparato ad pubblicare le pagine lette da un db access. Riesco a Leggere le informazioni tramite una pagina, e a Scrivere un nuovo record tramite un'altra pagina.
Ora il mio dilemma, è di potere visualizzare un record, e di poterlo direttamente modificare senza cancellare il record e quindi ricrearlo di nuovo.
Potete aiutarmi?
Grazie
Mille
Se non ho capito male, vuoi sapere come editare i dati del database attraverso un form, giusto?
1. Richiama il record
2. Crea una form per l'edit
3. Aggiorna il record con una query UPDATE
Esatto, voglio aggiornare i record attraverso un form.
Con Dreamweaver, ho creato una pagina .asp e un recordset.
Ho creato un modulo con dei campi testo assegnati a dei campi del recordset. Ho creato una barra di navigazione per spostarmi tra i record. Fino qui tutto bene, riesco a spostarmi tra i record.
Ora mi interessa aggiornare un record, quindi nella sezione Comportamento Server, creo un comportamento chiamato "Aggiorna Record".
Quando da internet tento di aggiornare il record, mi da questo errore:
Microsoft OLE DB Provider for ODBC Drivers error '80040e14'
[Microsoft][ODBC Microsoft Access Driver] Syntax error (missing operator) in query expression 'Al Cacciatore'.
/Pagine/database/ImmissioneTassaSociale4.asp, line 100
C'è sicuramente un errore nella stringa SQL. Però dovresti farci vedere il codice.

L'errore dovrebbe essere da queste parti
codice:MM_editQuery += " where " + MM_editColumn + " = " + MM_recordId;
Dovresti assicurarti che MM_editColumn e MM_recordId non siano vuote. In pratica dall'errore pare che la stringa SQL sia incompleta.
