Create Excel XLS from T-SQLScript Rating Total number of votes [30] By: David A. Long This is a T-SQL script that uses OLE, ADO, Jet4 ISAM, and Linked Server to create and populate an Excel Workbook (XLS) file from T-SQL query. If the Excel Worksheet exists, the query will append to the "table". The code is designed to be used by SQL Agent and to append to the step output with verbose and minimal detail. Code is pretty well commented, including some hard won knowledge about Jet4 ISAM, OLE, ADO, and usage of the Excel table from T-SQL-- Create XLS script DAL - 04/24/2003---- Designed for Agent scheduling, turn on "Append output for step history"---- 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
