Additional logic to answered question

This is based off of question ID: 28683827. I had a question on how to return the last value in a string after any variations of LCF in between company names. I want to add some additional logic to the function.

If the string ends with any of the variations of LCF and there is no company name after the last LCF I want to identify it somehow and I will write it to a table. Im thinking that if this happens I want something returned that I can look for(lets say the string '999' for now) and Ill write the bad value to a table.

Just so you know, the table with the bad records will be sent to the department that handles these names and they will enter the correct company and we will fix the data.

Small tweak to make the end in LCF work.  It will not return a NULL if there is nothing after the LCF.

WITH mydata 
     AS (SELECT 
     'MyText lost content for Company A LCF COMPANY B L/C/F COMPANY  C' col1 FROM   dual 
         UNION ALL 
         SELECT 'COMPANYA SERVICES INC L/C/F     COMPANYB TIRE EXCHANGE INC' col1 FROM   dual 
         UNION ALL 
	SELECT 'end with L/C/F' col1 FROM   dual 
         UNION ALL 
         SELECT 'HEllo' FROM   dual) 
SELECT
	Regexp_replace(
		Regexp_replace (Regexp_replace(col1, '[^[:alnum:] ]', NULL 
                                      , 1, 0, 
                                             'i'), 
                                            'LOST CONTENT FOR|LOST CONTRACT_FOR' 
                      , 'LCF' 
                             , 1, 0, 'i')
		, '(.*LCF ?)(.*$)', '\2') 
FROM   mydata 
/

Did you mean that it will return a NULL? Which is fine because I can simply evaluate that.

Yes, it WILL return a null...  or at least I hope...  since I can't type, I'm not sure.  ;)
