Oracle 更新并返回一个值
我在一张大容量桌子上有一个 Update Statement
.它一次只更新一行.
I am having a Update Statement
on a large volume table.
It updates only one row at a time.
Update MyTable
Set Col1 = Value
where primary key filters
随着这个更新语句的执行,我还想要一个值作为回报,以避免在同一个表上出现 Select Query
以节省资源.实现这一目标的语法是什么?
With this update statement gets executed I also want a value in return to avoid a Select Query
on a same table to save resources.
What will be my syntax to achieve this?

You can use the RETURNING keyword.
Update MyTable
Set Col1 = Value
where primary key filters
