Change what? what do you mean by delete row in middle?

Sorry, your question makes no sense. Please use the improve question function. Do you mean change a value of other records, because storing derived data is dangerous (you should try to derive on the fly). Your allusion to linked lists makes no sense either. If you want to implement a linked list in a database, you would need a home for pointers. If you want to keep data associated as a group, use a related table.
