| 释义 |
commit 【动】提交,调拨 To make changes to data(inserts, updates, deletes) permanent. Before changes are stored, both the old and new data exist so that change can be stored or the data can be restored to its prior state. When a user enters the SQL command COMMIT, all changes in that transaction are made permanent. 使更改数据(插入、修改、删除)为永久性的。在保存变更的数据之前,新老数据会并存一段时间,因此,既可保存新数据,也可恢复老数据。当用户使用SQL的提交命令COMMIT时,一个事务处理中对数据的全部变更将成为永久性的。 |
