I am looking to extract only the Serial No: value (1G20441XC454) from the following query result:
SELECT REGEXP_SUBSTR('Entry: Make: 1, Model: 6, Year: 7, Serial No: 1G20441XC454, Point of Origin: ', '<what would go here>') "REGEXPR_SUBSTR" FROM DUAL
So I need to find the string 'Serial No:' then find all characters up to the comma, then trim the value to remove the leading space. I also have to go on the assumption that not all comma-delimited fields will be present or in the same order. I am thinking this might require nested REGEXP?
