Question

I have a TO DO Table with a Position Column. (other columns removed for simplicity)

Description varchar(max)
Position int
JobFinished bit

If I have n amount of rows, each time a row is added the position is incremented. So values may look like this:

Drop Off Kids,   0, 0 
Get Groceries,   1, 0 
Pickup Kids,     2, 0

Now, If I do something I want to remove it from the table. And increment all other position columns so they are in order from 0.

Ie If I Get Groceries I need the values to look like this:

Drop off Kids,  0,    0
Get Grocerieis, NULL, 1
Pickup Kids,    1,    0

Is there any way with SQL I could do this?
(Im using SQL server)

Answer 1

This is very simple SQL question, just check your sql server reference, for the update SQL statement:

update todo_table set position = position -1 where position > 1;
update todo_table set position = NULL, JobFinished = 1 where Description='Get Grocerieis'
