WL#10676: DevAPI: asynchronous execution - part1 - fixes

rsomla1 · silvakid · commit 8953f17735e6 · 2019-07-25T15:07:47.000+01:00
Fix the issue when result meta-data is taken from a cursor - this cursor can be closed after reading all rows and then it is no longer possible to use it. But we copy meta-data to the m_mdata member and it can be taken from there instead.
