I know this command will create a directory:
EXEC master.sys.xp_create_subdir 'C:\testing\'
But how do I check whether 'C:\testing\' exists?
IF EXISTS(...
CREATE TABLE ResultSet (Directory varchar(200))
INSERT INTO ResultSet
EXEC master.dbo.xp_subdirs 'c:\'
Select * FROM ResultSet where Directory = 'testing'
Will return a list of sub directories, you can then check the contents of the list.
