IRR Function - Comparing Results Between Systems
Jan 13, 2012
I'm working on an income deferral problem and we are using IRR to end up calculating periodic income.
As an example, I have the following inputs:
Number of periods = 9
Initial Loan = 21.46
Instalment amount =15.30
Future value=0
Guess=0.1 (10%)
Using a compiled function from Visual Studio in SQL Server 2008 we get a result of 70.71656373
Using a Microsoft Access function we get NaN
Using Microsoft Excel we get NaN
Using a web calculator we get 70 (ish, the calculator rounds the numbers)
I know that the numbers are odd, some of our data is dirty so we do expect that. I was expecting the SQL process to kick out an error (therefore converting the result into 0), but it doesn't.

Is there a way to create a query which compares two result sets of results?
for example the result set of my first select statement is 7,1,8 and the second result set is 7,1,9..is there a query wherein i can compare the two results? i just wanted to reveal that there is a diffrence between the two..
thank you..

I have large stored procedures in SQL Server 2005 that often get updated. Sometimes it is very difficult to recognize how one change could impact the overall results. I would like to have some sample input that I could test during changes and see it compare the data results before & after my changes. This would help me quickly identify if the results are fine to pass through.
So basically I would like an easy way to compare the results of 2 stored procedures. Any suggestions or utilites that would help me do this?

Hi Guys, I am experiencing weird results
SELECT DSNew, DTTM, RQDT
FROM dbo.Feb
INNER JOIN DMSEFL
ON ACTR = DSNew
where cast(DSNew as varchar(20)) = cast(ACTR As varchar(20))
If I run the above query I get zero recs back.
If I substitute a Value then I get the desired results (ie. where DSNew = '93235500') or if I enter (ACTR = '93235500') or if I put (where DSNew = '93235500' AND ACTR = '93235500')
Can anyone suggest a reason why this is happening. I know the records exist on both tables I ran the query in Acess and got the desired resutls.
Thank you,
Trudye

I've inherited the following code:
SELECT TOP 100 PERCENT dbo._Options_Demographics.GradeLevel, dbo._Options_Demographics.Gender, dbo._Options_Demographics.Ethnicity,
dbo._Options_Demographics.Age, SUM(dbo._Options_Demographics.Enrollment) AS Enrollment, dbo._Options_Demographics.OptionsYear,
dbo._Options_Demographics.OptionsMonth
FROM dbo._Options_Confirmed INNER JOIN
dbo._Options_Demographics ON dbo._Options_Demographics.DistrictCode = dbo._Options_Confirmed.DistrictCode
GROUP BY dbo._Options_Demographics.GradeLevel, dbo._Options_Demographics.Gender, dbo._Options_Demographics.Ethnicity,
dbo._Options_Demographics.Age, dbo._Options_Demographics.OptionsYear, dbo._Options_Demographics.OptionsMonth
ORDER BY dbo._Options_Demographics.OptionsYear, dbo._Options_Demographics.OptionsMonth, dbo._Options_Demographics.GradeLevel,
dbo._Options_Demographics.Gender, dbo._Options_Demographics.Ethnicity, dbo._Options_Demographics.Age
which returns this data (the enrollment value is 4 times the correct value)
grade gender eth ageenrollyearmonth
8FemaleBlack1618112003December
8FemaleBlack1716212003December
8FemaleBlack187932003December
8FemaleBlack18P2872003December
If I remove the sum function and manually add, my totals are correct ...
SELECT TOP 100 PERCENT _Options_Demographics.GradeLevel, _Options_Demographics.Gender, _Options_Demographics.Ethnicity,
_Options_Demographics.Age, _Options_Demographics.Enrollment, _Options_Demographics.OptionsYear,
_Options_Demographics.OptionsMonth
FROM _Options_Confirmed RIGHT OUTER JOIN
_Options_Demographics ON _Options_Demographics.DistrictCode = _Options_Confirmed.DistrictCode
GROUP BY _Options_Demographics.GradeLevel, _Options_Demographics.Gender, _Options_Demographics.Ethnicity, _Options_Demographics.Age,
_Options_Demographics.Enrollment, _Options_Demographics.OptionsYear, _Options_Demographics.OptionsMonth
ORDER BY _Options_Demographics.OptionsYear, _Options_Demographics.OptionsMonth, _Options_Demographics.GradeLevel,
_Options_Demographics.Gender, _Options_Demographics.Ethnicity, _Options_Demographics.Age
I've been looking at this for too long and I know that is something very trivial ...

When I test the CAST function on AdventureWorks2012, the CAST function will round down or up, i.e. 2024.994 to 2025 or 5.1865 to 5.
However, when I try the same the CAST function as:
SELECTCAST(2024.994 AS INT) the result I get is now 2024 (and not 2025).
Why is CAST rounding up when I use it on a table in the AdventureWorks2012 database, but when I use CAST on its own, it rounds down?

Hello! My group uses scalar-valued functions to denote the FTP drives on our SQL Server 2005 database servers. This allows many (over 100) import processes to refer to that function to find the flat files they need, and if the FTP drive is changed, then only the function needs to be updated, not 100 SP's.
The function is defined this way. Currently, F: is our FTP drive:
CREATE FUNCTION [dbo].[fnFTPPath] ()
RETURNS varchar(200) AS
BEGIN
return 'f:'
END
Now the question: Can a Flat File Connection Manager be used in an SSIS ETL package that refers to the output of this function, plus the FTP folder name, so we can continue updating the FTP drive name in just one place? If so, how is this done?
Thank you!

hi guys,
i am encountering a pretty weird problem on our SQL database stored procs, particularly those concerning datetime functions. we have two setups, one is on london, and another one is here in singapore. both servers have the same regional settings, the same database tables, stored procs and functions, almost the same in every aspect. the only difference we know is that one is a direct database cut (sql 7.0), while the other used database migration in win2k.
here goes: all stored proc functions work just fine on the singapore setup. the london setup however, is not working at all! it does all the functions like change flags and status, but it doesn't update dates nor search for data by date. i have also checked on the collision names, and they are the same. where else could i start searching for discrepancies between the two?
hope to hear something from you guys, i'm getting desperate. thanks in advance!

When I get result from .NET console app, I get correct answer "JungleSektor". However, when SQL Server executes this code, it gives me "NT ServiceMSSQL $ SQL2014". How to get correct result?

Hi,Say I have a table Job with columns name, date, salary . I want to getthe name ,date and salary for the date when that person earned maximumsalary. I am using something likeSELECT X.name,X.date,X.salaryFROM job XWHERE X.salary IN(SELECT MAX(Y.salary) FROM job Y where Y.name= X.name);The problem is ; if a person earns maximum salary on two dates, both ofthe dates are printed. I just want to get any one of those two rows.I triedSELECT X.name,Min(X.date),X.salaryFROM job XWHERE X.salary IN(SELECT MAX(Y.salary) FROM job Y where Y.name= X.name);but it gives error.Can anybody please suggest a solution?Regards,Aamir

Hi
I regularly use the T-SQL date functions to return the 1st of a particualr month.
e.g.
SELECT DATEADD(m,DATEDIFF(m,0,getdate()),0)
returns 2007-05-01 00:00:00.000
i.e the first of the current month at midnight.
However, when I try to use a similar expression as a derived column in SSIS it returns a completely different date.
DATEADD("month",DATEDIFF("month",(DT_DATE)0,GETDATE()),(DT_DATE)0)
returns 30/05/2007 00:00:00
Any ideas why and how I can obtain the first of a particualr month using SSIS derived column?

I'm working with the statistical functions Stdev and Median with calculated members. The only way I can get the "correct" answer is if I have a dimension at the same granularity as the Fact table (Actually it's a degenerate dimension of the FACT table itself). Otherwise it seems that the measure I'm using with Stdev returns results that are so wildly high, I think it must be acting on the SUM of the measure; because the measure itself is a Summed one. When I try to use the coordinates in the Stdev function, it seems like it is using the wrong set of data points :
stdev( ( [Date].[Date].[Date].members, [Parameter].[Parameter].[Parameter].members ), [Measures].[Value])Â returns answers in the thousands when it should be more like 2.5
When used with a query, there would only be a single date member and a specific parameter member. The total number of fact records is between 200 and 500 with values that range between 0 and 150. This is the version that gives me answers that resemble the total sum of the [Measures].[Value].
If I add the dimension that is essentially a row number from the fact table, it gives the right answer (slowly, but that will be a different post ....
stdev( ( [Date].[Date].[Date].members, [Parameter].[Parameter].[Parameter].members, [FACTTable].[FACTTable].[KeyField].members ), [Measures].[Value])

Hi
I have a UDF
---------------------
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[UDF_AlphaNumeric]') and xtype in (N'FN', N'IF', N'TF'))
drop function [dbo].[UDF_AlphaNumeric]
GO
CREATE function UDF_AlphaNumeric (@string nvarchar(max)) returns nvarchar(max)
AS
-- select dbo.UDF_AlphaNumeric('a[]#b`c,;"1$%^2"£!3')
begin
while @@rowcount > 0
select @string = replace(@string, substring(@string, patindex('%[^0-9a-zA-Z]%', @string), 1), '')
where patindex('%[^0-9a-zA-Z]%', @string) <> 0
if @string = ''
select @string = null
return @string
end
---------------------
After creating the function I open a new query window, put in the below two calls to the function, and run them
select dbo.ADE_AlphaNumeric('a432[]#b`c,;gfd23$%^789')
select dbo.ADE_AlphaNumeric('a432[]#b`c,;gfd23$%^789')
The results then look like this:
a432[]#b`c,;gfd23$%^789
a432bcgfd23789
The first time it runs, it's not having the desired effect. Any subsequent calls to the function perform as expected.
I am using SQL Server 2005 SP2. Is this a known issue? Or is there some setting I am missing?
Cheers
Neil

Hi, have configured an ODBC linked server for an Adaptive Server Anywhere (ASA6.0) database.
I have to write a function (not a procedure) that receives a number (@Code) and returns 1 if it was found on a table in the linked server, or 0 if not. Looks very simple...
One problem, is that the queries on a linked-server must be made through the OPENQUERY statement, which doesen't support dynamic parameters. I've solved this making the whole query a string, and executing it, something like this:
SET @SQL='SELECT * FROM OPENQUERY(CAT_ASA, ''SELECT code FROM countries WHERE code=' + @Code + ''')'
EXEC sp_executesql @SQL
(CAT_ASA is the linked-server's name)
Then, i would use @@ROWCOUNT to determine if the code exists or not. But before this, a problem appears: sp_executesql is not allowed within a function (only extended procedures are allowed).
Does somebody know how to make what i want?? I prefer to avoid using temporary tables.
Thanks!

I need to syncronize two separate databases. One is SQL Server the other is MySql. I don't have a lot of experience with MSSQL and need a little advice on how best (in terms of speed especially) to gather records that have been added since the last sync and any that have been modified. The table in question has datetime fields for both, the time each record was created (CreatedTime) and the time that the record was last modified (ModifiedTime). Sync will happen daily.
I have worked out a few ways I might do this with DATEADD or DATEDIFF, but my question is, what is the most effecient way? Currently I'm just looking for a way to get inserted and updated records from SQL Server to MySQL. I may have to do a two way sync of some sort later.

I have a client that would like to archive all of the documents .word, .xls, .pdf, .jpg, email coorespondance, etc. into some sort of database so in the near future when the project starts up again all of the information is in a clear consise format. I was hoping that this forum could provide some guidance in selecting a software package and a discussion on how to proceed.
I have 6 gigs of documents in a folder on our server.
I was planning on delivering the organized data on a external hard drive after putting the data into some sort of database.
I would like to include metadata about each particular document.
like
who created the document,
Key words about the document's purpose,
time frame the document is revelant for,
and so on.
I would like to use a database structure and possibly hot link the document to the DB.
I would like to use xml (if possible) for the metadata.
any help is greatly appreciated on this
I can be reached at
khively at maximusa dot com

Hi everyone,
Im having a hard time deciding what approach should I take. The scenario is this: I have developed various systems (inventory, HR, accounting, etc.). All this systems are (and should be) tightly integrated with one another. At present, for all these systems, i've used a single DB prefixing the tables with the systems name (eg. Inventory.Items).
My question is: did I did the right (and practical) thing? Or should I create a DB for each system to organize them? The problem with multiple DBs is some system uses the other system's table(s). Example, if i created a separate DB for accounting, and a separated DB for inventory, and another for HR, how am I going to relate inventory and HR's accounts to the accounting DB's table? I want a single instance for each table; I don't want to create another account table for inventory or HR so I can enforce integrity. And if different DBs, is there a performance impact on this?
Or is there another way? My concern is performance and manageability. Please help. Thanks!

I currently run SQL Server 2005 64-bit Developer Edition (Service Pack 2 - it will be SP 3 as soon as I can get hold of it). I am running this on a stand-alone box with Windows Server 2003 as the OS.
Soon, I will be buying another computer for a colleague who will be running SQL Server as specified above. However, I am not happy with Windows Server and am wondering about changing to either XP 64-bit or Vista 64-bit. The machine will not be networked.
I would welcome advice on this since, in some ways, I would be happy enough to use XP or Vista, and think that 64-bit development is more likely on Vista than on other Windows OS's. However, I am not convinced that SQL Server 2005 works with Vista and, like everyone else, have heard plenty of complaints about Vista.
All advice gratefully received.
Thanks.

The db server runs on Win2003.Right now we're thinking about what file system to use on the newdrives. We opt for performance, but expect reliability as well.(Goeswithout saying, IMHO ;-))

I was going over this article , and was intrigued by this statement "If SQL Server 2005 Express is running on Windows XP Home, it is limited to five simultaneous connections. If it is running on Windows 2000 or Windows XP Professional, it is limited to 10 simultaneous connections. However, these are limitations of the operating system and not of SQL Server 2005 Express."
What are simultaneous connections? Is this related to Max worker threads defined as 255 on other editions? How does underlying OS impose how many connections can be done to SQL server. And finally how many simultaneous connections can be done in Windows Server 2003?
