How to retrieve col information by labview database connectivity toolset?

[lvvl]

Hi, there,

The list table vi in the toolset output only col name, data type and
size? how can I know NULL allowed or not? Also it seems that the list
table vi always gives back '-1' even though it is a string type.
Somebody have some experience on it?

Thanks a lot.
