I have a table with a composite key ID and revision. 我有一个带有组合键ID和修订版的表。

When I "insert" a new record I want to auto increment the ID. 当我“插入”新记录时，我想自动增加ID。 When I "update" the record I want to actually insert a new record but increment revision. 当我“更新”记录时，我想实际插入一个新记录，但增加修订。

What is the proper table settings for this? 正确的表格设置是什么？

What I have done in the past is actually use a trigger for UPDATE . 我过去所做的实际上是使用UPDATE触发器。 It would copy all the values into a new record and increment the version column. 它将所有值复制到新记录中，并增加版本列。 I would also have an indexed column that would serve as a key, but not a primary key so that all revisions would be tied together. 我还将拥有一个索引列，该索引列将用作键，而不是主键，以便将所有修订版本捆绑在一起。
