Remarks

Deletes all baskets that match a supplied search clause and supplies a count of the number of baskets deleted.

Delete operations should be carried out in small chunks. Extensive delete operations can lock the baskets table and degrade site performance significantly for current customers. If the amount of baskets is large (e.g. during peak season), run the command multiple times during the day, or use a datetime range that breaks up the large count of baskets into smaller ones.

In order to perform a DeleteBaskets, the user must have the OrdersAdministrator permissions. See Orders System Roles [CS06] for more information about the specific roles in the Order System.

Some order system APIs support distributed transactions. If a cookie with a valid transaction is found the order system enlists as part of that transaction. If a valid transaction is not found the order system initiates a new transaction.

Examples

The following code sample deletes all baskets created on or before the current time (Effectively deleting all baskets).

OrderManagementContext orderSystem = new OrderManagementContext("app.config");
BasketManager basketmanager = orderSystem.BasketManager;
// Build the search clause.
DataSet searchableProperties = basketmanager.GetSearchableProperties("en-US");
SearchClauseFactory factory = basketmanager.GetSearchClauseFactory(searchableProperties, "Basket");
SearchClause clause = factory.CreateClause(ExplicitComparisonOperator.OnOrBefore, "Created", DateTime.Now.ToUniversalTime());
basketmanager.DeleteBaskets(clause, out recordsDeleted);
