Does calling the clear member function on variant clear the vt data member too?

Rather than declaring several variants I wish to use one for several data extraction of query execution result.

I noticed that _variant_t has the clear member function, does function also the vt member data apart from the encapsulated VARIANT?

Solution 1

_variant_t::Clear internally calls the VariantClear[^] API.
VariantClear sets the vt data member to VT_EMPTY which is the value 0.
