what should i do when i want update table with "new button", but not doing anything with (getCurrentRecord() or getNextSelectedRecord()). just simple click button then update value in table . just query , example : UPDATE detail SET price = 10000;
In order to update you need a parameter for the "where" part and you get this with getCurrentRecord() or getNextSelectedRecord(). If you just want to update without condition you can do that (like a bulk update) but it would perform horribly as it would go through every row in the table and every price will be set to 10000! So you could take a custom button and use just the server part with the query you said.
