Question

I couldn’t find a way to do it and am not sure how to search for this question, as all I’ve found were not exactly what I wanted and the answers not applicable.

I have a table with two fields (char and num), ‘num’ is unique but ‘char’ not, as in the example:

char | num
_________
a    | 2
b    | 1
c    | 3
c    | 4 <-- I am here
c    | 7
c    | 8
d    | 5
e    | 9
f    | 6

what I want is to fetch N rows beginning in the line marked with the table ordered by ‘char’.

I’m using

SELECT * FROM table WHERE char >= $current_char ORDER BY char,num LIMIT $N

but it doesn’t do what I want, as it starts from the row with char=’c’ and num=’3′.

EDIT: I will probably count and use xdazz’s answer because the code will be clearer, but it looks that I could do this other way:

SELECT * FROM table WHERE char > $current_char OR (char = $current_char AND num >= $current_num) ORDER BY char,num LIMIT $N

but it is not very pretty.

Answer 1

You marked <-- I am here means you know that is the forth record, so you could just do :

SELECT * FROM table ORDER BY char,num LIMIT 4, $N
