My Grandma came over yesterday:
Hey Grandma.
Hello darling, what are you up to?
Ugh, well, I’m stuck. I’m trying to understand adjacent lists, modified pre-order tree traversal and x-depth recursive nested queries, to get this SQL statement to work.
Hmm, have you tried limiting your query loops to a set depth? That’s what your Grandad and I always do. Or a four-way left outer self join might do it, to show the current level, plus 3 levels of the tree?
Well that’s just it, I don’t want to go that route. It’s too limiting.
Yes… tricky. Well, why don’t you give that nice foreign man, Rudy Steinbeck a call, dear. He’s always been very helpful in the past hasn’t he?
It’s ‘Limeback’ Grandma, ‘Steinbeck’ was the Of Mice and Men chap. But good point, old thing, I’ll give Rudy a buzz.
And you know what, she was right. She might not have the first clue about appropriate SQL statements ("a four-way left outer self join" — I ask you!) but she surely knows her database gurus.
Rudy Limeback: The LEFT-JOIN Lothario of Toronto; The Query-Kidd of Canada; The 2003 SitePoint Database Guru of the Year, is my SQL go-to guy. And he could be yours as well.
Rudy’s list of achievements are pretty impressive: one of the founding members of Evolt; Technical Editor at Digital Web magazine; published author; and last year’s SitePoint Database Guru of the Year. He’s a remarkably friendly, talented and affordable fella.
Rudy Limeback has worked with commercial databases since the mid-1970’s, starting with IDMS, a Codasyl network system, and progressing through IBM’s DB2 and Microsoft’s SQL Server relational databases. He has developed data warehouses and transactional databases, always with an emphasis on making them easy to use for developers and end users alike. He specializes in writing SQL statements that are simple and easy to maintain
In 1997 Rudy took a year’s sabbatical from SQL work to prepare for his biggest challenge to date — to become the last man to tightrope walk over Niagara Falls before the practice was outlawed. Unfortunately bad weather and a terrible bout of diarrhoea put paid to this heroic feat, and Rudy, bowed, but not broken, returned to the fold and his place as the industry’s SQL Man Of Choice.
As a contractor, Rudy is always looking for work. So if you have a job, no matter how large or small, get in touch with him. He’s easy to find, easy to work with, easy to pay, and very effective.
