Hi Zoran

>>Hi Guys,
>>I am converting a VFP app to SQL Server Database. This app has stock control and about 50 users use the system simultaneously. A lot of inventory management. I need to use pessimistic locking, So the stock on hand gets incremented or decremented depending on the type of transaction. In VFP I issued a Rlock() on the record, updated and then released it, how do I achieve this in SQL. Any help will be appreceiated.
