Question

I have a table with a varchar column with values that should be integers (legacy application, built way before I got to the company).

I need to get a list of all the records that cannot be converted to integers, in order to fix them.

How can I do this?

Answer 1

A simple way is:

select MyColumn
from MyTable
where isnumeric(MyColumn) = 0

That assumes you are OK with losing decimals when you convert.
