Hello,
I've a table mt ( mt1 NUMBER(10) NOT NULL ) with unique index on the mt1
column.
There's a sequence of numbers 1,2,3,4,6,7,8,10,11 ... in the mt1
Now, I want to get the smallest number which is not in mt1
(excluding min(mt1)-x of course) into XY (in my example is it n. 5
select MIN(a.mt1)+1 INTO XY FROM
(select mt1 FROM MT MINUS SELECT mt1-1 FROM MT) a;
is better, but still full scan ...
