idx | int | ident
1   | 10  | Foo 001_10
2   | 10  | Farfoo 002_11

5   | 10  | MoreFoo 001_11

How can I select all rows where the last 2 characters in the string ‘ident’ do not match the integer in the ‘int’ coloumn? Which for the table above would be:

2   | 10  | Farfoo 002_11
5   | 10  | MoreFoo 001_11

Answer 1

You can also use RIGHT string function using
right(ident,2) you will get the last two digits from string then compare it will int column
if both are unequal then retrieve the not matching contents.

select * from tablename
where RIGHT(ident,2) != int;
