Create Excel XLS from T-SQL

—
— Search for %%% to find adjustable constants and other options
—
— Uses OLE for ADO and OLE DB to create the XLS file if it does not exist
—   Linked server requires the XLS to exist before creation
— Uses OLE ADO to Create the XLS Worksheet for use as a table by T-SQL
— Uses Linked Server to allow T-SQL access to XLS table
— Uses T-SQL to populate te XLS worksheet, very fast
—
