I'm wondering how to calculate the current possible row width if all data where filled to max. I'm just curious if I'm approaching the 8060 max.

I have a parent record en some child records.
Let's say the child records have a field with a value in the range 1-9
Now I want to find the maximum value in the child records.
When I have that value, I want to write this value in a field in the parent record.
1) Should I do this in a (update) trigger?
2) How do you write such a trigger in sql-express?
thanks Klaas

I have a fact table which lists the last 12 month historical sales of a product,country,month combination so the table structure is like:
<month, productID, countryID, (month-3 sales), (month-4 sales).........,(month-14 sales)>
I need to write an MDX query which will return a flag that indicates if a product has a gap of more than 2 consecutive months in terms of positive sales. So I calculate if there is a gap of 3 months. If yes, then return 1 else null. The calculation below is scoped at product level.
IIF(([month-3 sales]<=0 AND [month-4 sales]<=0 AND [month-5 sales]<=0)
OR ([month-4 sales]<=0 AND [month-5 sales]<=0 AND [month-6 sales]<=0)
OR ([month-5 sales]<=0 AND [month-6 sales]<=0 AND [month-7 sales]<=0)
...............
OR ([month-12 sales]<=0 AND [month-13 sales]<=0 AND [month-14 sales]<=0)),1,NULL)
Unfortunately I cannot do this calculation at relational level as a product may have a gap of more than 2 months at country level but may not have this at a higher level in geography.
optimizing this as the performance is bad and other calculated measures are dependent on this. Based on this calculation, I can write a scope which sums up all products so that I get the count of products with a gap of more than 2 months in sales.
I have also tried CASE statement and NESTED IIFs but the performance is worse than the above.
We are close to exceeding the Maximum Row size of 8K per row and the CIO asked me "how close are we to reaching the 8K row limit?"
I began by looking at byte requirements for the data types we are using
from the systypes table then I wondered, do the indecie, Foreign Keys and Primary Keys use bytes which must be included in my Calculation for current number of bytes used per Row.
Question: How do I calculate Current total number of bytes used per row.
I need to calculate “NET_SALES” and “MARGIN_PERCENT” for each month of the current year … the following returns the same values for each month in the list, which are for the current month. Taking out the GROUP BY line works fine for an overall number.
SALES_MONTH, NET_SALES, MARGIN_PERCENT
January, 1246627.69, 24
February, 1246627.69, 24
March, 1246627.69, 24
-------------------------------------------------
DECLARE @NetSales DECIMAL(18,6)
DECLARE @Cost DECIMAL(18,6)
SELECT
@NetSales = sum(IL.MERCHANDISE+IL.TAX)
,@Cost = sum(IL.COST)
FROM INVOICELINE IL

I'm trying to create a WHERE statement that will calculate values from our current fiscal year to the last complete month.I'm using code that was created for us that does the calculations for our entire fiscal years. I thought I had fixed the WHERE statement to work like we wanted last year, but it appears to be broken now after trying it again in January and February. I'm guessing my WHERE statement only works for March and up, but how to get it to work for every month. Most attempts I'm trying it's just returning very large and inaccurate values.
I included my WHERE statement below of what I originally had that worked last year. The @BeginYear/Month/etc are retrieved from a different table and @Month is just set to MONTH(GETDATE())-1.
WHERE
(YEAR(SA3.DocumentDate)=@BeginYear AND MONTH(SA3.DocumentDate)>=@BeginMonth AND MONTH(SA3.DocumentDate)<=@Month)
OR
(YEAR(SA3.DocumentDate)=@EndYear AND MONTH(SA3.DocumentDate)<=@EndMonth AND MONTH(SA3.DocumentDate)>=@Month)
Hi,
I'm using SQL Server 7.0 SP3.
I need to calculate the average size of a record in my database to assist in estimating growth.
Is there a quick and/or easy way of doing this?
Thanks in advance,

I have a view that selects various fields, from various tbls.
When I run that view it erros out as follows:
Could not insert a row larger than the page size into a hash table. Resubmit the query with the ROBUST PLAN hint.
It seems like 1 particualr record, is exceeding the rowzise. and hence the errors.
How can I resolve this..
I have some code I build 2 weeks ago which I’ve been running daily but it’s suddenly stopped working with the following error.
“The table "tbl_Intraday_Tmp" has been created, but its maximum row size exceeds the allowed maximum of 8060 bytes. INSERT or UPDATE to this table will fail if the resulting row exceeds the size limit” When I google this there seems to be a related to tables with vast numbers of columns.
My table tbl_Intraday_tmp is relatively small. It has 7 columns. 1 of varchar(5), 3 of decimal(9,3) and 2 of decimal(18,0). The bit I’m puzzled with is it was working and stopped.
I don’t recall changing anything but I wouldn’t rule that out. I ‘ve inspected the source files and I don’t believe they have changed either.
DECLARE
@FileName varchar(50),
@Path varchar(50),
@SqlCmd varchar(1000)

Hi,I read this article on net recently.http://joseph.randomnetworks.com/archives/2005/08/30/sql-server-2000-maximum-row-size-8060-bytes/And according to it, SQL Server 2000 have around 8K of Row Size.Now consider this , i have table have two column and in each column i have inserted data around 6k.Now my question is , how sql server is going to store this.Is it in 2 different Row ?Can any one explains this or provides links related to it.ByeAmit

I get this mysterious error while running an update.
SQLServer tells me that my update row is to big to fit in a row.
Then I check the size of the row and and it is like 2000 bytes so
it should fit without any problem at all. The really strange about
it that when comments a field it works just fine. That field is always
null. Could that be the problem. Anyone who have ever had a similar
problem or so?
I have a select statment that gives me an error, cannot go more than rowsize 8094.
I am trying to find the particualr record/acctno, where the rowsize is excedding the max limi of 8094 chars. Once I have the acctno, I will correct it.
But how do I find which acct has this issue? Bascailly how can I find which record size is more than 8094 chars?

I have a SQL2000 database where the developers have a tool which creates screens and tables at the same time. During cleanup (dropping of some columns in these tables) I recieved the below error message
Warning: The table '%.*ls' has been created but its maximum row size (%d) exceeds the maximum numberof bytes per row (8060). INSERT or UPDATE of a row in this table will fail if the resulting row length exceeds 8060 bytes.
Apparently the tool is not sophisticated to recognize this problem. I looked at MS KB and it stated that inserts and updates may fail due to this. I probably know the answer to this, but has anyone else encountered this before, and what if any kind of problems did it cause. I am sure it is a no-brainer that this is asking for trouble, but if anybody has any experience with this issue all input appreciated.
SQL Server 2000 8.00.760 (SP3)I've been working on a test system and the following UDF worked fine.It runs in the "current" database, and references another database onthe same server called 127-SuperQuote.CREATE FUNCTION fnGetFormattedAddress(@WorkID int)RETURNS varchar(130)ASBEGINDECLARE@Address1 As varchar(50)@ReturnAddress As varchar(130)SELECT@Address1 = [127-SuperQuote].dbo.tblCompany.Address1FROM[Work] INNER JOIN[127-SuperQuote].dbo.tblCompany ON [Work].ClientID =[127-SuperQuote].dbo.tblCompany.CompanyIDWHERE[Work].WorkID = @WorkIDIF @Address1 IS NOT NULLSET @ReturnAddress = @ReturnAddress + @Address1 + CHAR(13)+ CHAR(10)RETURN @ReturnAddressENDSo now the system has gone live and it turns out that the live"SuperQuote" database is on a different server.I've linked the server and changed the function as below, but I get anerror both in QA and when checking Syntax in the UDF builder:The number name 'Zen.SuperQuote.dbo.tblCompany' contains more than themaximum number of prefixes. The maximum is 3.CREATE FUNCTION fnGetFormattedAddress(@WorkID int)RETURNS varchar(130)ASBEGINDECLARE@Address1 As varchar(50)@ReturnAddress As varchar(130)SELECT@Address1 = Zen.SuperQuote.dbo.tblCompany.Address1FROM[Work] INNER JOINZen.SuperQuote.dbo.tblCompany ON [Work].ClientID =Zen.SuperQuote.dbo.tblCompany.CompanyIDWHERE[Work].WorkID = @WorkIDIF @Address1 IS NOT NULLSET @ReturnAddress = @ReturnAddress + @Address1 + CHAR(13)+ CHAR(10)RETURN @ReturnAddressENDHow can I get round this? By the way, I've rather simplified thefunction to ease readability. Also, I haven't posted any DDL because Idon't think that's the problem!ThanksEdward

SELECT

FROM RESULT WHERE t1.Date>=CONVERT(VARCHAR(10),DATEADD(d,-7,GETDATE()),101) AND
t1.Date<CONVERT(VARCHAR(10), GETDATE(), 101)
Let's say, current date is 8 AUG 2005 and current time is 2045
So, i will get

t1.Date<CONVERT(VARCHAR(10), GETDATE(), 101) AND TIME<=CurrentTime
If current date is 8 AUG 2005 and current time is 2045, so the result shown as follow

Hi,
I'm making some sort of application where people can add their resume.
They also need something to add places where they have worked or currently are working.
I have a form where they can add this and i add this experience using the following stored procedure:
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
create procedure [dbo].[sp_Insert_Experience]
@ExperienceId uniqueidentifier,
@ExperienceEmployee nvarchar(100),
@ExperienceFrom datetime,
@ExperienceUntil datetime,
@ExperienceQualifications nvarchar(250),
@ExperienceTechnologies nvarchar(250),
@ExperienceTasks nvarchar(250)
as
insert into Experiences
values(@ExperienceId,@ExperienceEmployee,@ExperienceFrom,@ExperienceUntil,@ExperienceQualifications,
@ExperienceTechnologies,@ExperienceTasks);
It must be possible to add the place where they currently are working. Then the ExperienceUntil has to be something like still going on. Then I decided that the user then had to set the current date.
But what I want is the following, I want that the ExperienceUntil keeps updating automatically, like everytime i get that record, it has to have current date.
Is this possible ?
But if the ExperienceUntil isn't the current date , it just had to take the supplied parameter date.

Hi Everybody,
Our development team is doing some stuff in ASP. They are interested only in char and varchar
data types. They clearly told us that they are not going with text and image data types.
Is it possible to make a row size behind 8060 bytes in a table without text and image data types?.
tks in advance,
Sri.
Hi,
I have a table with 188376 rows and the data size = 3012 KB, index size = 5884 KB .
LE threshold max is set to 2000 and LE threshol percent to 20%
I have an index on that table and observed that it is not getting used.
I would like to know whether sql optimizer uses the index based on the cost
of the query plan or does the table scan once the LE thresholdlimit is reached
overriding the optimized plan.
thanks,
MMS

My query is this:
SELECT
ProdspecUID
,itemcode
,model
,revno
FROM prodspec
The revision numbers (revno) are unique per itemcode.I would like to get only the rows with the highest revision per itemcode, but I also need the prodspecUID with is the index key and therefore unique.I have tried MAX() and TOP 1's in sub queries, but up until now without any result.
Hello
Without technical information and DB design, I wish to know the maximum entries in MS SQL in million. I guest for access are a limit of 2 million and a 2GB DB.
How much for MS SQL in max. entries and how much in GB?
A lot of thx for your feedback.
