注解

DataAdapter检查每次执行插入、更新或删除操作时受影响的行数, 并在数字等于零时引发此异常。The DataAdapter examines the number of rows affected by the execution of each insert, update, or delete operation, and throws this exception if the number equals zero. 此异常通常是由并发冲突引起的。This exception is generally caused by a concurrency violation.
