I have the following trim statement

(right(rtrim([RSA_Record_Key_String]),len(reverse(substring(reverse(rtrim([RSA_Record_Key_String])),(0),charindex('-',reverse(rtrim([RSA_Record_Key_String]))))))))

However some of the records don't have a - in them and just contain charactors. These records return no value How can I modify this so that it will always return a value?

Example:

1-abc-23 returns 23
1-abc Returns abc
1 is not returning anything right now and I would like it to return 1

You have to do something so the substring function gets valid arguments. Following is shorter and may be sufficient:

 STUFF('x'+[RSA_Record_Key_String],1,CHARINDEX('-',[RSA_Record_Key_String])+1,'')

Note that rtrim and ltrim are functions and not statements.
