What do you mean? Let us, say, you have:

store SQLSTRINGCONNECT(;
	'Driver={SQL Server};'+;
	'SERVER=.......);
	TO gnConnHandle

* your code goes here

?SQLGETPROP(gnConnHandle,"ConnectBusy")  && will give you .T. or .F., or the message "connection handle is invalid" if it is 0 or already disconnected.
