Re: Removing Last field from CSV string

[Samuel Roseman <muelrose@xxxxxxxxx>]

Regular expressions, in my opinion, can be a very powerful text search and replace engine if you know how to use it.

Feel free to enhance what I provided below; it seems to work for the example you provided.

postgres=# select regexp_replace(substring('Class V,Class VI,Class VII,Competitive Exam,Class VIII,Class X,Class XI,Class IX,Class XII',1,60),'(.*),\w+','\1');

                     regexp_replace                     

--------------------------------------------------------

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

(1 row)

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.

Thank you

Alex
