However , no effort is made to compare updates against the original record ; the record is simply written out , potentially overwriting any changes made by other users since you last refreshed the records 但是，不会将更新与初始记录进行比较；而只是写出记录，这可能就改写了自上次刷新记录后其他用户所进行的更改。
This is useful for situations such as issuing a select statement after an update or insert statement in order to get back refreshed records and any auto - generated values such as default or auto - increment values 这在类似下面的情况下很有用：在更新或insert语句之后发出一条select语句以取回已刷新记录和任何自动生成的值（如默认值或自动增加的值） 。
