This stored procedure can be used to insert the result set of the

particular select statement into Excel file (c:\ImportToExcel.xls,

by default).

You can pass the server name, user name, user password, the select

statement to execute, and the file name to store the results set,

as in the example below:

EXEC ExportToExcel @server = '.',

@uname = 'sa',

@QueryText = 'SELECT au_fname FROM pubs..authors',

@filename = 'c:\ImportToExcel.xls'
