What's the problem to use% over in case of access?

I do not think there is more to it.

In the olden days, Internet Explorer will not let you zoom in one page sizes were specified in pixels, but if they allow users or users to see content at a suitable size for% Recommended to stay away from pixels.

Nowadays, all modern browsers have zoomed a whole page, which units you use

I often use pixels when things are completely ready, And when fonts and paragraph margins etc need to be shaped to keep a vertical rhythm.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ....").

If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
