Default Convert Crystal reports from Access to Oracle

I have developed a software in VB6 (backend Access). Now I have changed the back end as Oracle 9i. This software contains near about 50 reports. which I developed in Crystal Reports (Backend Access). Can anybody help me to change the backend of crystal reports (i.e. from Access to Oracle 9i) because this is very lengthy process for me to develop all the reports again in Oracle 9i.

The problem is that , the table an field names in Access database are in mixed letters and in Oracle 9i they all are in CAPITAL letter, the Crystal reports were created using the mixed alphabets of Access , Please tell me what can i do.

Thanks.

Mixed case is not an issue for oracle when it comes to SQL, SQL is NOT case sensitive.
Questions:
What version of crystal are you using. ?
Are the database schemas from Access and Oracle identical?
Are you doing a lot of date comparisons in your report queries? Access and Oracle do not handle dates in the same way (if you are comparing dates with a date string)
Are you passing crystal recordsets from VB or is crystal getting the data right from the database through its own queries (In other words, where is the data access happening)?

I have had problems simply changing the table name in a Crystal report I imagine changing the database is going to cause you several headaches.

Bob.

If your Reports are based on Database Tables and the Table Names are the same in Access and Oracle (Change of Case is not a problem), I can give you a small VB procedure to Convert the Database Driver and Location of each Table of each report. You must have at least Crystal Report 8.0 or higher.
