Christ, if you could see the abysmal efficiency of business tier SQL code being churned out in the Lowest Bidder mines overseas...

Using a few terrabytes of memory and a stack of processors as high as my knee so they can recreate Excel in a badly rendered .aspx page built in 2003.

We have a table with literally three columns. One is an id, another a filename and a third a path. Guess which one was picked as the primary key?

Never seen something so stupid in 28 years of computing. Including my studies.

Well, you don't want to waste space by adding the same file path twice

As a dev, I had to fix an O( n! ) algorithm once because the outsourced developer that wrote it had no clue about anything. This algorithm was making database queries. To an on-device database, granted, so no network requests, but jesus christ man. I questioned the sanity of the world that time, and haven’t stopped since.

Oh yeah, I love people who stick SQL lookups in a For Loop. Even better, the coder who puts conditional if (but no then/else) clauses around a dozen raw text execution commands that fire in sequence. So you're making six distinct lookups per iteration rather than answering your question in a single query and referencing the results from memory.
