£20-250 GBP

Paid on delivery
I need two SQL scripts that query postgres’s information schema tables, finding all the ’attribute’ tables of a given ’anchor’ table, to (1) create a denormalized view, which joins the anchor to it’s attributes, and (2) creates an empty temporary denormalized table which represents the attribute tables joined to the given table (with some additional columns). Please see the attached [login to view URL] file that provides more details and the [login to view URL] script that creates a set of tables that can be used to develop the denormalization scripts against.

Hi, I went through the requirement and details are quite clear. I would be able to do this as I come with 9+ years of experience in PostgreSQL. Although I am new to freelancer but I can message you my Linkedin profile to be sure. Can you please also tell which version of PostgreSQL you are using right now, as some information schema changes have happened in subsequent versions. Any further queries we can discuss in message.
