I want to hold ordering of some items in SQL, like field in a table index: 0,1,2,3,4,... and I have operation moveItem

If I want to move item from index: 1 to index: 3 I can do

delete from table where index = 1;
update table set index = index - 1 where index > 1
update table set index = index + 1 where index >=3
insert into table (index) values (3)
