Re: Sybase proc with return value, results, IN & OUT params

[Clinton Begin]

This may be one of those cases where you have to write it in JDBC....even as just a test to see if it works with your database driver.  Once that's done, you can post it here and we can see if there's anything iBATIS is doing to cause the problem. 

At first glance, I'm wondering if it would even work with plain old JDBC (it should, but the driver may not support it)...

Cheers,
Clinton

I am trying to call a sybase stored proc which returns results set and a return value, has input paramters & output parameters. 

I need to know how to to get the
1. return value ( 0 on success, -1 on failure)
2. out parms values - as_error, as_error_msg
3. Result set list ( if success)

 

Thanks,
