Result:-Close - close a Result module

Calling Sequence

result:-Close( )




Result module



Close frees the resources associated with result.  This happens automatically when result is garbage collected; however, you can call Close to release the resources immediately.


Any descendant modules of result are closed when result is closed.  (A module is a descendant of a parent module if it is returned by one of the parent module's exports or if it is a descendant of one of the parent module's descendants.)


Create a Result, res.


conn:=driver:-OpenConnectionurl,name,pass:res:=conn:-ExecuteQuerySELECT * FROM animals:

Close res.


Try using res.


Error, (in ExecuteQuery) this object has been closed, no further operations are possible
