I have a table that contains NULL values but the problem is that some of the values are actually string "NULL" and not actual NULLS so when you trying something like
where date is null
it will not return the fields that have the "NULL" string.
What I am needing to do is run an update of the whole table that will convert all string "NULLS" to the actual NULL value. The "NULL" strings happen throughout all columns of the table so it is not just 1 column that needs to be updated. I am not sure how to approach this scenario. I'm thinking I might need to use a loop since i have many columns but then again there might be a simple solution without having to use a loop. What would be the best way to resolve this issue?
