I have a MySQL table with the column 'id', and the only thing I know about it is the content of one cell in 'id' column.
I want to go one entry before and one entry after the known 'id' entry.
Example:
| Id | ...
| A | ...
|13 | ...
| B | ...
I want to know what A and B are, I don't know what row 13 is and A and B are not necessarily 12 and 14... Any ideas?
