MySQL Select Query - Get only first 10 characters of a value

Ok, so here is the issue. I have a table with some columns and 'subject' is one of the columns. I need to get the first 10 letters from the 'subject' field no matter the 'subject' field contains a string with 100 letters. For example, Table - `tbl`. Columns - `id`, `subject`, `value`. SQL Query: ``` SELECT subject FROM tbl WHERE id ='$id'; ``` The result I am getting is, for example Hello, this is my subject and how are you I only require the first 10 characters Hello, thi I can understand that I can remove the rest of the characters using php substr() but that's not possible in my case. I need to get the excess characters removed by MySQL. How can this be done?
