SQL Saturday #96 happened in Washington, D.C. yesterday, and it was a great event. It is a special event to me because it was my first opportunity to speak at a PASS event and give back to a community that has given me much and transformed my queries for the better time and time again. If you are visiting my blog because you came to one of my sessions, please leave me some feedback on the presentation -- constructive criticism is as welcome as praise.
If you would like my PowerPoint presentations along with the .sql files I used for the demos in SQL Server Management Studio, you can download them from the SQL Saturday #96 Schedule page.
And in the same vein as my comments on the PASS Summit, I'm going to post the top ten things I learned yesterday. These are in roughly chronological order.
1. If you ever go to a SQL Saturday event, definitely use the Speed Pass and print it off before you to the venue on the day of the event. If you don't, you'll likely be in a line waiting to check in before you can join the fun.
2. Apparently Twitter or some Twitter-related organization ranks people's "influence" based on their tweets and the number of people who respond to them. This ranking is quite important to many people, and it was a point of animated discussion in the speaker's room at this event.
3. I discovered that people who are coming to T-SQL and SQL Server from Oracle and other platforms can benefit from an introductory course such as my introduction to Common Table Expressions, even when their time of experience with SQL is greater than mine. I suppose this is self-evident, but it was a little eye-opening to me.
4. Even though features have been around since SQL Server 2005, some people who have been using T-SQL for a long time may have overlooked a feature that I take for granted now, such as the window functions. I was a little pleased when I heard a couple of attendees express surprise that it is possible to generate an aggregate value without a GROUP BY clause because it meant that I had something to share that I knew could help them tremendously.
5. Receiving applause for a presentation is truly gratifying, even when it is a customary act done for every presenter. It seemed authentic in both my sessions, and therefore it was meaningful to me.
6. It seems that for most Business Intelligence professionals, having the primary justification for having a data warehouse is the ability to create an OLAP cube for analysis. I'm not sure that will be my justification. I think its primary benefit as a companion to our OLTP database would be to capture historical data for slowly changing dimensions and a close second or even a tie for first would be to enable a clearer semantic model for our end users in report design.
7. The date dimension generally adds the most overhead to any OLAP cube because it generally adds 365 rows x however many years are tracked. If there is any way to summarize to the weekly granularity or less, that will be a huge win for the efficiency of the cube.
8. It is ever clearer that any data warehouse that might be built as a companion for the Shelby v.5 OLTP database will include a single "EntityNames" role-playing dimension that contains all the entity attributes across all the available modules supplemented with views that take the core table and breaks out the module-specific attributes.
9. Even a large software company like Microsoft can overlook a feature that the end user sees as patently obvious. The case in point for today is the ability to update automatically all the Reporting Services reports that use a report part that has been changed. It's a manual process for now.
10. The built-in change tracking mechanism in SQL Server may be a great option for customers who want to know when things have changed at a more detailed granularity than we capture in the OLTP tables. But it only captures three days' changes by default, so a secondary mechanism for moving that data to a flat file or supplemental table is needed to go further back from there.
There you have it, my top 10 things learned yesterday at SQL Saturday #96. I'll return to blogging more procedural stuff after today. Let me finish this entry by saying that I really enjoyed the privilege of sharing my knowledge with the PASS community, and I hope to have similar opportunities in the future. If I do, you'll definitely be reading about it here. :-)

Simple BFS Query for YTD/Annual Values and No Projects
I was recently asked to help a customer with a Budgeted Financial Statement type query that could be pushed to the Shelby v.5 Dashboard. The customer was only looking for year-to-date actual values and annual budget values. There was no need to break out by Project code. Such a request greatly simplified the query writing process over what I have been doing and documenting in previous posts. Without needing to break out Project codes I could use the GLSummary table, which already aggregates the actual transactions for each period for each account. Without needing to do any specific period reporting, I could use the GLBudget table in its native form, without unpivoting it into periodic rows. For this project I also ignored budget revisions, which further simplifies the query.
I have also discovered recently that ShelbyQUERY supports the use of WITH to define inline views before the main query's SELECT clause, which is great because if you need the same view multiple times in the main query, you can use an alias instead of typing the whole thing each time. It also moves the bulk of the view syntax out of the FROM clause, meaning that the main query's FROM clause is much more readable. One thing to remember if you are using WITH to define an inline view is that any lines of SQL code that come before it must be terminated with a semicolon. The only thing that might come in front of that in ShelbyQUERY would be variable DECLARE and SET commands. Generally the semicolon is optional for DECLARE and SET, but if there is a WITH, the semicolon is not optional.
In the query below I used a WITH statement to define the subquery that adds the columns that make it possible to do Total Line aggregates to the basic GLAcct table. I have already explained how that piece works in previous posts. I also have five variables so that the user can define a fiscal year, a company number, a fund number range, a department number range, and whether or not the Period 13 (commonly called the audit period) will be included in the calculations.
declare @FiscalYear as smallint, @CoNu as tinyint, @FundStart as smallint, @FundEnd as smallint, @DeptStart as smallint, @DeptEnd as smallint, @UsePeriod13 as varchar(1);set @FiscalYear = 2008;set @CoNu = 1;set @FundStart = 0;set @FundEnd = 999; set @DeptStart = 0;set @DeptEnd = 999;set @UsePeriod13 = 'Y'; -- Change to 'N' to exclude Period 13

Querying the General Ledger with Total Lines - Actuals
In the earlier post on this topic I included a query that would add ten columns to the basic GLAcct table. These extra columns would allow you to summarize by Total Line right in a query. In this post I will share a query that will allow you to get the period actuals for all the accounts, including total lines. It will also provide extra lines for Project values. If you want to remove the Project level detail, just remove the Project line from the SELECT statement and from the GROUP BY statement.
Most reports need to be able to report on one or more periods, so in order to generate either a pivot table with the ability to pull any period or create a Report Designer that can prompt the user for a period, we need to multiply the accounts in GLAcct thirteen times, one for each possible Period (don't forget about the Audit period, which is period 13). To do this, we will add in a Cartesian Join between GLAcct and an inline view that is nothing but the numbers 1 through 13:
select *from Shelby.GLAcct, (select Period = 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9 union select 10 union select 11 union select 12 union select 13) as PeriodsWe then substitute this in place of the reference to Shelby.GLAcct in the original Total Line query given in the previous post, and we have this (above query in italics below):
select A1.CoNu, A1.BeginDate, A1.FundNu, A1.DeptNu, A1.AcctNu, A1.LineType, Descr = max(A1.Descr), StmtType = max(A1.StmtType), A1.Period, T0 = sum(case when A2.LineType like '[0-9]' then 1 else 0 end) + case when A1.LineType = 'D' then 1 else 0 end, T1 = sum(case when A2.LineType like '[1-9]' then 1 else 0 end) + case when A1.LineType = 'D' then 1 else 0 end, T2 = sum(case when A2.LineType like '[2-9]' then 1 else 0 end) + case when A1.LineType = 'D' then 1 else 0 end, T3 = sum(case when A2.LineType like '[3-9]' then 1 else 0 end) + case when A1.LineType = 'D' then 1 else 0 end, T4 = sum(case when A2.LineType like '[4-9]' then 1 else 0 end) + case when A1.LineType = 'D' then 1 else 0 end, T5 = sum(case when A2.LineType like '[5-9]' then 1 else 0 end) + case when A1.LineType = 'D' then 1 else 0 end, T6 = sum(case when A2.LineType like '[6-9]' then 1 else 0 end) + case when A1.LineType = 'D' then 1 else 0 end, T7 = sum(case when A2.LineType like '[7-9]' then 1 else 0 end) + case when A1.LineType = 'D' then 1 else 0 end, T8 = sum(case when A2.LineType like '[8-9]' then 1 else 0 end) + case when A1.LineType = 'D' then 1 else 0 end, T9 = sum(case when A2.LineType like '[9-9]' then 1 else 0 end) + case when A1.LineType = 'D' then 1 else 0 endfrom (select * from Shelby.GLAcct, (select Period = 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9 union select 10 union select 11 union select 12 union select 13) as Periods) as A1 left join Shelby.GLAcct as A2 on A1.CoNu = A2.CoNu and A1.BeginDate = A2.BeginDate and (A1.FundNu > A2.FundNu or (A1.FundNu = A2.FundNu and A1.DeptNu > A2.DeptNu) or (A1.FundNu = A2.FundNu and A1.DeptNu = A2.DeptNu and A1.AcctNu >= A2.AcctNu)) and isnumeric(A2.LineType) = 1group by A1.CoNu, A1.BeginDate, A1.FundNu, A1.DeptNu, A1.AcctNu, A1.LineType, A1.PeriodNow we need to take the entirety of this result and use it as an inline view, add a join to the actual transaction history table, which is GLDetail, and then construct a SELECT clause that can sum up the numbers as needed. Here is that query. (Warning: This only works on SQL Server 2005 or later. If you are running MSDE or SQL Server 2000, this will not work for you.) Also, this query will return all fiscal years of all companies. This may take a long time to run (15 mintues + for some organizations). Add a WHERE clause to limit the results to just one fiscal year and company to shorten the time. (The above query is in italics below.)

It uses the T0 through T9 columns as the leverage it needs to get the sum values. Windowing functions are great ways to do aggregate values on a scalar set of results or to aggregate an aggregate, as I did here.
This only gets the actual values. Getting the budget values is actually a bit harder, especially with a Project breakout. I'll post more query solutions with budget values in them later.
If you have questions, feel free to post a comment. I'd love to know if this blog is meeting anyones needs or at least of interest to some people.
