Filtering Out Letter Values, Leaving Numeric Values

DomoDave

I have a field with letter and numeric values (ex. "John Doe" vs. "12345"). My goal is to filter to leave the numeric values and change the column type to Integer.

Does anyone have any ideas on how to do this in ETL? Trying to think of a Case when statement & filter option.

You can use the REGEX_REPLACE() function. REGEXP_REPLACE(yourField, '[^0-9]+','')

For those that don't like to use REGEX, you can use this function to quickly remove non-numeric characters:

STR_DIGITS(STR)Returns a new string consisting of only the digit characters in str in the order they appear.
