| A table is used for storing current number of Sales OrderCurrentNumber| name | prefix | current_number || SalesOrder | SO | 10 |I got multiple users to access this row to get the latest numberINSERT INTO SalesOrder (id,field2,...) SELECT (prefix + RIGHT('000' + CAST(current_number AS VARCHAR(4)), 4)), value2,... FROM CurrentNumberThen update the current_number to 11How to add locking on this row to prevent two users create sales order with same number? Thanks for any comments. |
