Test for numeric value?

Question

The vendor data we load in our staging table is rather dirty. One column in particular captures number data but 40% of the time has garbage characters or random strings.

Answer 1

Check this out:

SELECT Mobile, 
 TRANSLATE(Mobile, '~~~~~~~~~~', '0123456789') AS FirstPass, 
 TRANSLATE(TRANSLATE(Mobile, '~~~~~~~~~~', '0123456789'), '', '~') AS Erroneous, 
REPLACE(TRANSLATE(Mobile, '', TRANSLATE(TRANSLATE(Mobile, '~~~~~~~~~~', '0123456789'), '', '~')), ' ', '') AS Corrected 
 FROM Person WHERE Mobile <> '' FETCH FIRST 100 ROWS ONLY

The table is "Person" and the field that you want to check is "Mobile". If you work a little bit more on this, you can build an UPDATE to fix the entire table
