Question

I want to create a batch delete and/or update screen for records similar to how the iphone lets you batch delete text messages In other words when you click edit, it shows a checkbox next to all the records and you can then click a button that deletes them or changes a value.

I have discovered following syntax to insert a bunch of rows:

insert into tbl (...) values (...) (...) (...) ...

There also seems to be a way to batch delete using:

delete from tbl where id IN (1,2,3)

Is there a way to do a batch update?

I think I could then just collect an array of the id numbers for the records and run either a delete or update query depending on what button is pushed.

Answer 1

You can use WHERE condition same like you did for DELETE query like this:

UPDATE tbl SET col1='...', col2='...' WHERE id IN (1,2,3)
