Create a slug before inserting a row

[Anonymous]

Hi everyone,
that's my first post on this forum, so hello
I came here because I'm struggling with something. For each product I insert in the db, I must create a slug (from its name) that will be used in further URLs. Basically it just replace every special characters with an '-' and checks that it is unique.
For example a product named "Playstation 3 160Go", the slug should be "playstation-3-160go".
But if there are two products with the same name but that are differents somehow, the slug should still be unique and therefore have a number at the end.
For example if a there are 2 products named "Playstation 3" in the db (one black and one white), the respective slugs should "playstation-3" and "playstation-3-1".

So my question is, is there a native way to do that in Talend when inserting row in a table ?
If not, what's the best way ?
Thanks !
Guillaume

There is not native way or any way supported natively by a database. I would strongly suggest using a administration table for your slugs. This table should have a field for the slug text and an auto increment id field.
For the slug column you should add a unique index on the table.
You can try to create a slug in the first step like your rule and if this slug is already present you should read the existing one and add "salt" to it.

Thanks for you answer.
Actually I changed myapproch a little. Instead of trying to have the exact slug creation system I described, I went to something custom where I slugify the name and concat it with its id. So I don't have to manage an extra table.
PS : By slugify, I mean that I have a Java snippet replacing all special characters with '-'
