Hi,

I have a string that I want to cut to 60 char and then remove the last field and comma.

substring('Class V,Class VI,Class VII,Competitive Exam,Class VIII,Class X,Class XI,Class IX,Class XII',1,60);

substring | Class V,Class VI,Class VII,Competitive Exam,Class VIII,Class

Now I try to remove the last  field and comma  ",Class"

To get  Class V,Class VI,Class VII,Competitive Exam,Class VIII

Is there a function or easy way to do this?

Any help would be appreciated.

You should be able to write a posix patter that does this, you want to keep everything except a comma followed by 0 or more non-commas and the end of the string boundary to make sure it gets just the last such match.
