SQL Query Stuck in Infintite Loop -


i'm running pretty simple sql query on database, , seems returning same record on , over, creating infinite loop. maybe i'm missing obvious, don't see it. here's query:

select s.customer 'customer',     s.store 'store',     s.item 'item',     d.dlvry_dt 'delivery',     i.item_description 'description',     mj.major_class_description 'major description',     s.last_physical_inventory_dt 'last physical date',     s.qty_physical 'physical qty',     s.avg_unit_cost 'unit cost',     [qty_physical] * [avg_unit_cost] value database.delivery d,     database.store_inventory s,     database.item_master i,     database.minor_item_class mi,     database.major_item_class mj,     database.store_inventory_adjustment sa sa.store = s.store     , s.last_physical_inventory_dt between '6/29/2011' , '7/2/2011'     , s.customer = '20001'     , s.last_physical_inventory_dt not null

there 1 record falls on 7/1/2011 , repeats forever until cancel query.

any on preventing this?

you're joining these tables: database.delivery, database.item_master, database.minor_item_class, , database.major_item_class - without specifying how join them. need specify how these tables joined rest.

if each of these tables has 100 rows, give 100 * 100 * 100 * 100 rows (100 million) minimum rows! (see cartesian join)
