Обсуждение: Get DB Size by row

Hello,

I'm looking to do something like:

select month, mb_size(description) from data where year = 2012 group by month

I also am looking for raw size not compressed size.

Thanks

Ben

octet_length() will give you the size in bytes.  It's not the size in
characters, though, unless the field is using an encoding that's always
1 byte per character.  For character length, use (obviously)
character_length().
