Brandon / David,
I haven't had a chance to look at the code much, but I think that
problem is to be expected. A quick glance at the C++ code shows that
SQLRETURN is getting set like this:
context->SetObjectVariable("SQLRETURN"
My understanding is that the SetObjectVariable API is setting an
*instance* variable in the context of the method.
This is the same as using expose in a subclass and then expecting the
attribute in the parent class to reflect the change. It won't work.
/* qTest.rex */
db = .dbconnx~new
db~doSomeThing
say 'sqlReturn:' db~SQLRETURN
say 'sqlDiag: ' db~SQLDIAG
::class 'cli' public
::attribute SQLRETURN
::attribute SQLDIAG
::class dbconnx public subclass cli
::method doSomeThing
expose SQLRETURN SQLDIAG
SQLRETURN = 15
SQLDIAG = "Error"
Output:
C:\work.ooRexx\other>qTest.rex
sqlReturn: SQLRETURN
sqlDiag: SQLDIAG
C:\work.ooRexx\other>
On the other hand this will work:
/* qTest.rex */
db = .dbconnx~new
db~doSomeThing
say 'sqlReturn:' db~SQLRETURN
say 'sqlDiag: ' db~SQLDIAG
::class 'cli' public
::attribute SQLRETURN
::attribute SQLDIAG
::class dbconnx public subclass cli
::method doSomeThing
expose SQLRETURN SQLDIAG
self~SQLRETURN = 15
self~SQLDIAG = "Error"
Output:
C:\work.ooRexx\other>qTest.rex
sqlReturn: 15
sqlDiag: Error
C:\work.ooRexx\other>
That's why your patch worked Brandon, and the current code in the
incubator doesn't work.
