Hi guys,

i've got this column:

path_name character varying(255)

I store full S3 bucket path for the attachments of my application on it; example:

/{s3bucket}/filesuser/client/27801123/attachment/4510/main

/{s3bucket}/filesuser/client/27801123/attachment/4510/file

I wanna do a select, where path_name has only 'main' and not anything else.

WHERE path_nane LIKE '%/main'

I was able to do it like this:

WHERE (path_name)::text ~ '^\/filesuser\/client/\d+/(attachment)/\d+/(main)+'

Thanks

Patrick.

 Guys.. sorry but actually it's not exactly what I'm looking for:

The paths /{s3bucket}/filesuser/client/27801123/attachment/4510/main /{s3bucket}/filesuser/client/27801123/attachment/4510/file are the root path for:

/{s3bucket}/filesuser/client/27801123/attachment/4510/file/1113/small/photo.jpg

/{s3bucket}/filesuser/client/27801123/attachment/4510/main/111/small/photo.jpg

So for that single file (photo.jpg) i can have:

/{s3bucket}/filesuser/client/27801123/attachment/4510/file/1113/small/photo.jpg
/{s3bucket}/filesuser/client/27801124/attachment/4511/main/111/small/photo.jpg
/{s3bucket}/filesuser/client/27801125/attachment/4512/file
/{s3bucket}/filesuser/client/27801126/attachment/4513/main

select REGEXP_REPLACE(path_name, '.*/', '') as col2 from seg_table limit 10;

It works, but I get :

photo.jpg
main
file

When actually I just want the 'main''

How can I include this regexp in a where clause? Something like:

WHERE REGEXP_REPLACE(path_name, '.*/', '')::text = 'main'

Thanks!
Patrick.
