Looping without cursor not updating properly

#275015

I got asked to not use a cursor for a loop that I'm working on so I grabbed the code here:
http://www.sql-server-performance.com/2004/operations-no-cursors/
And adjusted it to do what I need. It's not updating how I'm expecting it to. If I comment out the part where it subtracts one from the town count, then it treats everyone as if the first if statement were true. If I don't comment it out, then it treats everyone as if both the first and second are false because it is subtracting all the counts from the towncount and making it 0.
There's probably some stupid syntax thing that I'm forgetting or just not realizing I need. I'm late getting this out, and I have staff getting calls about this lottery, so I was hoping I could get some help. Thanks for any suggestions you can make that'll help me find an avenue for pursuit. (sorry for the big indenting I can't seem to get it to stop doing that)

Welcome to SSC. As it appears you are new here there are some things you need to do to helps help you and for you to get better answers to your problem.

First, start by reading the first article I reference below in my signature block regarding asking for help. The instructions in that article will help with the information you need to post and how to post it.

We really do need the DDL (CREATE TABLE) statement for the table(s) involved, sample data (as a series of INSERT INTO statements) for the table(s) involved, and the expected results based on the sample data. Please note, we aren't asking for actual, confidential data as sample data. We just want data that is representative of your problem domain and the problem you are trying to solve.

You do this and you will get good answers in return plus the code provided will be tested against the data you provided.

Didn't realize which forum I was on or that I was so new. Thanks for the tips, sorry for the inadequate post.

Lynn Pettis SSC Guru Points: 442467 More actions · Answer 3

Don't apologize for your post. I've looked at the code you posted, it's just that there isn't enough there to really work with. Since we don't know the table structures or the data you are working with we can't setup a test environment on our systems to properly work the problem.

As volunteers we rely on you to provide us the information we need to be able to help you. The more you can do to helps, the better help we can provide you. In addition, you get the benefit of tested code as well, not just something thrown together that might possibly be a solution to your problem.

Just worth noting, a while loop is just as much a cursor as an explicitly defined cursor. It just doesn't have the keyword. It's still a loop, it's still processing a row at a time, it's still slow.

I got asked to not use a cursor for a loop that I'm working on so I grabbed the code here:

http://www.sql-server-performance.com/2004/operations-no-cursors/%5B/quote%5D

To emphasize what Gail has stated, they should outlaw articles like the one you provided the link for. Probably most important is the fact that the author has produced absolutely NO performance stats on the two methods and, like many of us had in the early days until we tested, has bought into the myth that Temp Tables or Table Variables and While loops are more efficient than Cursors. A well written "firehose" cursor is just as effecient and easier to code than such alternatives. It's usually a total waste of time to convert Cursors to alternatives. You won't actually believe it until you prove it to yourself with code.

Don't buy into the "Cursor Replacement Myth" of replacing cursors with While Loops and Temp Tables. It usually makes no difference. If you feel you must, just convert the cursor to a "firehose" cursor and call it a day.

What you should buy into, however, is that there's usually a very high performance method to avoid RBAR (see my sig line below for definition) altogether. Even multiple set-based passes on a Temp Table will blow any While loop away whether in a Cursor or not.

I will third that opinion. This is an argument that I have heard time and again that a while loop is more efficient. Yuck.

Here is a good article on comparing/ converting cursors to while loops and why the conversion just isn't what is advertised by that sql-server-performance article referenced above:

Getting back to the problem at hand, I did a read of the code and I don't readily see the problem. I'll take another look after I get some shuteye.

Here's my attempt at providing enough information so you can help. 🙂

I wasn't sure how to give you all the necessary code, so I'm dropping it all in at the end of my description here. I also, after I'd posted last week, gone back and tried redoing this as a cursor in the hope that it was simply my unfamiliarity that might be at issue, and I'm having the same problems even with the cursor. Since I've already posted my first attempt without the cursor above, I'll only add the second attempt with the cursor after all the set up code at the bottom.

Every year there's a lottery held to award the right to harvest on state-owned firewood lots to citizens. There is a web application they apply through (I did not write it, I didn't design any of this, I inherited it when a coworker suddenly passed away last year). The old code was using cold fusion and Microsoft Access with just two tables on an SQL Backend. I'm trying to update this so that I don't have to go through the laborious Access process my predecessor had set up without having to rewrite everything he did (we're not replacing the cold fusion, yet for instance, it works well enough for now). So the task at hand is to set up the code that will award the lots appropriately.

There are a specific number of lots awarded in different towns. The towns and the numbers of lots available changes every year. There are also specific numbers of alternates awarded afterwards. I was intending to simply create a second process the mirrored the first to do the alternate awards. I'm hoping that the comments in the code will make it clear what the process is, but I'm concerned that I might be bogging this down, so if you need me to outline the lottery procedure, I can do that, too, just let me know.

Nice attempt at posting ddl and sample data. I would recommend you try running your code prior to posting. There are literally hundreds of issues with what you posted. Some are reasonably simple to fix (adding a GO between procs) but others are just too much to deal with. Your insert into FirewoodLottery has more things wrong than it has right. If you can clean this up so it is usable we can have a crack at this.

I apologize for my fumbling attempts, I've never tried to do anything like this before, and several of the commands are unfamiliar to me. Here is another try at the dll. I have one problem in that it won't populate the sample data and I don't know why it won't. It throws this error: Msg 205, Level 16, State 1, Line 7

All queries combined using a UNION, INTERSECT or EXCEPT operator must have an equal number of expressions in their target lists.

I've double checked (and fixed some problems). When I count the fields in the insert, compared to those in the creates and the sample data lists, they all appear to be in agreement as to the number of fields.
