Might be worthwhile to first query the commodities table and put the results into a #temp table indexed on commodityID, then join to the #temp table.   Depends on how many...

Can you direct the output from the SQLCMD script to a text file, then open it using OpenRowset??

Are there no SYBASE forums?   😉
