Question

I created an inventory system which mostly is using a server-sided scripting language to do all the work. To try and get some performance gains I am looking to better design my database to try and minimizing the scripts.

I have a table named metal_part which has a one to one relationship with five other tables, basically the other tables are other parts, which those parts then have a one to one relationship with a few other tables.

When I query metal_part I need all the UPC numbers from each table, so its direct one to one relationships need to get their own information from their direct one to one relationship tables ect… Is it possible to make a huge query to build it all and put it in a form at like:

(###) - ####/##/##/## [a-z]

Using a query? or do I have to get all the information and concat it using a scripting language?

Thanks

You should be able to get all of the information you need using a standard join, and then, with the concat function appropriate to your database (see here http://www.1keydata.com/sql/sql-concatenate.html) you can form the string you want.
