Question

I would like to delete all rows where Value is empty (\'\'

Answer 1

Google send me here looking for a way filter all rows with an emoji on a varchar column. In case that your looking for something similar:

SELECT mycolumn
FROM mytable
WHERE REGEXP_EXTRACT(mycolumn,'\x{1f600}')  <> ''

the \x{1f600} is the char code for the searched emoji, you can find the emoji codes here
