VB 5.0 (RDO) & ORACLE 8

Recently i finished working on a Sybase System 11 project with VB4.0 and am supposed to start work on ORACLE8 & VB5.0 project.
Need some help on figuring out How do you call "Stored Procedures/Packages" from VB4.0/5.0 using RDO. In Sybase used to execute Stored Procedures as prepared statements returning multiple resultsets. Has anyone worked on a similar project.

Any Tips, Clues appreciated.

Thanx in advance & all help, pointers to information else where , sample code is more than welcome

Thanx
Manoj

I will save bandwidth here by referring you to "Processing Multiple RDO Result Sets" topic in Visual Basic On-line Books series "Guide to Building Client/Server Applications with Visual Basic".

I wanted more specific details obviously. Maybe the answerer may not be aware of the specifics of ORACLE8 with respect to RDO.

Can close this.

Thanx

To be honest, we have had a lot of experience with Oracle 7.3 and RDO (VB5). My guess is that the ODBC driver that you use has more ramifications for your VB code than RDBMS.

In your question, you have asked for help on calling stored procedures. With Oracle, especially when IN/OUT variables are used in Stored Procedures, we use ODBC Call Syntax ("? = Call Foo (?,?,...?))". For starting, you should probably use UserConnection object which retrieves stores procedure list from Oracle and tries to identify the direction of the variables used in the definition of the stored procedures.

To use multiple resultset queries, there are two methods: 1) opening resultsets on connection, 2) using rdoQuery. We prefer the latter approach since it gives better handle. To define the WHERE clause in the query, just use question mark as parameter place holder and use rdoParameters to assign/retrieve parameters. You can only access one resultset at a time, so process the first resultset, execute "MoreResults" method of the rdoResultSet to access additional resultsets.

I hope the above information is useful. However, if you still need more information, I suggest that you let me have a specific query, I will be very happy to give you VB code to handle that.

tks.
