Hi
Can somebody tel me any peculiarity of getColumnListMetaData function?I'm totaly new to Oracle and OCCI and the function seems to be strange for me.For example when I call it from the function, that takes a string as a parametr ( SomeClass::Execute(const string & szQuery) or even SomeClass::Execute(string szQuery) it fails with segmentation fault,when I put data longer than some maximum (for my case it was 37 charachters) ).When I use char * instead of string all is ok.The next strange feature is that I need to clear the returned vector of MetaData before closing ResultSet.Otherwise I get segmentation fault.I tested it all with a table,that has 2 fields ,or with a query resulting one or two columns.So I'd made everything worked fine,but just changed a query to return more than two columns I got *** glibc detected *** free():invalid pointer ..
Tell me smth, I must know about hwo this function works and possible errors while using it.
Thanks in advance.
Yura.
