UR::Da...tColumn(3pm)

💖 NAME 💖

okay so bestie, lemme introduce you to UR::DataSource::RDBMS::PkConstraintColumn — she's a whole class and she's literally the metadata about a data source's primary keys. iconic behavior, no notes. 🎀

(this one ships inside the UR::Da...tColumn(3pm) manual, iykyk ✨)

🌸 DESCRIPTION 🌸

so what does she even do, you ask? 🦋

UR::DataSource::RDBMS::PkConstraintColumn represents the columns that make up a primary key. that's it, that's the job. main character energy only. 💅

and here's the cute little detail that matters — when a table has a multiple-column primary key, those columns get ordered by their rank property. like, rank decides who goes first. periodt. 👑

lowkey important: if you're dealing with a composite PK, don't sleep on rank, bestie. that's the whole ordering system fr fr. 🫶
