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

[Clinton Begin]

Unfortunately, if the results are inconsistent, iBATIS will have trouble with it.  My suggestion would be to wrap the oddball stored proc with another proc that supplies a more predictable API and behaviour.

Cheers,

It works in JDBC and  code is shown below.  It prints out all -ie. error code, message, return value and either sql error message ( no results) or result set  

Note: It also works (ie returns all desired values as in JDBC ) in ibatis only when the query succeeds ie have result sets and passes any paramter condition checks.  But fails/exception  when the proc call   does not pass parameters check  or no results - it then DOES NOT  return the OUT param values and  Return Value set in the proc.

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

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)...

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,
