Select Statement that returns a result where the text characters contains only 0s or only 9s but length doesn't matter

Question

I'm trying to write a select statement that returns column A when column B contains '0' or '9' or '00' or '99' or '000' or '999' and so forth. The values are TEXT. Any help is appreciated!

Answer 1

You could use:

SELECT colA
FROM tab
WHERE REPLACE(colB, '9', '') = ''
   OR REPLACE(colB, '0', '') = '';
