jpa - Alternatives to EntityManager's merge() method -

-

I was thinking that there is a way to update other than using the merge () method, in many cases In which I need to update a field on the database, and to do this, I have to call the merge method to bring the entire object from DB with my relationships, set new values ​​and go through the modified object. It works fine, but it is causing some functionality issues, because I have to take some data from the database unnecessarily before updating. The way I see it is better to execute the update without bringing any data into memory.

Has anyone already thought about it and is an alternate and more effective way to do this?

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
