How To Filter On Maximum Value

Oct 23, 2013

how to filter on a maximum value ?

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.

Transact SQL :: Error - Maximum Row Size Exceeds Allowed Maximum Of 8060 Bytes

Sep 12, 2015

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)
= '',
@ASXCode varchar(5),
@Offset decimal(18,0),

[code]....

...Contains More Than The Maximum Number Of Prefixes. The Maximum Is 3.

Oct 10, 2005

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

Automatic Select Filter (something Like Global Table Filter)

Apr 15, 2008

Hello,

Here is my problem:


I use SQL Server 2005. I have approx. 50 tables in my database and 30 of them have a filed named "CompanyID". Example:
create table A (ID int identity, NAME varchar(100), COMPANYID int)create table A (ID int identity, REF_ID int, FIELD1 varchar(100), FIELD2 varchar(100), COMPANYID int)

Also there are nearly 200 stored procedures that read data from these tables. Example:
create procedure ABCasbegin /* some checks and expressions here ... */ select ... from A inner join B on (A.ID = B.REF_ID) where ... /* ... */end;

All my queries in the Stored procedure does not filter the tables by CompanyID, so they process the entire data.

However, now we have a requirement to separate the data for each company. That means that we have to put a filter by CompanyID to each of those 20 tables in each query where the tables appear.

Firstly, I put the CompanyID in the context so now its value is accessible through the context_info() function. Thus I do not need now to pass it as a parameter to the stored procedures.

However, I don't know what is the easiest and fastest way to filter the tables. Example:

I modified the above mentioned procedure in the following way:
create procedure ABCasbegin /* some checks and expressions here ... */
-- gets the CompanyID from the context: DECLARE @CompanyID int; SELECT @CompanyID = CONVERT(float, CONVERT(varchar(128), context_info()))
select ... from A inner join B on (A.ID = B.REF_ID) where ...
and A.COMPANYID = @CompanyID and B.COMPANYID = @CompanyID /* ... */end;

Now I have the desired filter by CompanyID. However, modifying over 200 stored procedures is rather tedious work and I don't think that this is the best approach. Is there any functionality in SQL Server that can provide the possibility to put an automatic filter to the tables.
For example: when I wrote "SELECT * FROM A", the actual statements to be executed would be "SELECT * FROM A WHERE CompanyID = CONVERT(float, CONVERT(varchar(128), context_info()))".

I was looking for something like "INSTEAD OF SELECT" triggers but I didn't manage to find any answer.

I would very grateful is someone suggests a solution for something like "global table filter" (that will help me make an easy refactoring)?


Thanks in advance.

Best regards,
Beroetz

And/or Filter Field Not Enabled In The Group Filter Tab

Jan 26, 2006

Howdy,

I have a table that has a group. In this group, I want to filter by 2 different expressions, concatenated with an OR. BUT I can't change the "And/Or" column value for the first entry because it is grayed out. The column will automatically change to an OR value if both my expression column fields are the same (which I dont want) but if I put any other value in to the expression field of the second row, the "And/Or" field of the first row automatically changes to an AND.

PLEASE! How do I get the And/Or field "ungrayed" so I can change it to what I want?

The 2 filters I and using check the UserID = to the user, and the other is checking a count to get the Top N 1. (So just showing the current user and the top producer)

Maximum Capacity Of A ROW!

Nov 29, 2000

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,

Le Threshold Maximum

Feb 9, 1999

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

Minimum/Maximum Of Two Values

Dec 6, 2004

Hallo Cracks,

what I try is a little bit heavy, maybe, but I only miss the minimum/maximum fuction - or I didn´t found it; not here in the Forum and also not in the onlinehelp of the SQL Server.

What I try to do:

I have 2 columns in my table; a start- and an end-date. For this period of time between end and start i have to calculate the days for the years. Here my thoughts (for the current year):

Is the startdate <= 31.12.2004 and the enddate >= 1.1.2004 i have to calculate die datediff between max(1.1.2004/startdate) and min(31.12.2004/enddate)

like this sqlstatement:

SELECT CASE WHEN dbo.Phases.phasenstart <= CAST(CAST(YEAR(GETDATE()) AS
varchar) + '-31-12' AS smalldatetime) AND dbo.Phases.phasenabschlussist >=
CAST(CAST(YEAR(GETDATE()) AS varchar) + '-01-01' AS smalldatetime)
THEN 365 ELSE 0 END AS Expr2,
FROM dbo.Phases
WHERE (phasenstart IS NOT NULL) AND (phasenabschlussist IS NOT NULL)

instead of 365 there must be the above calculation. Is start=3.1.2003 and end=30.1.2004 I expect as result only the 30 days in 2004.

thanks in advance and kind regards :-)

How To Increase The Maximum No. Of DB Processes?

Sep 4, 1998

I am receiving an error from my ODBC driver Maximum number of DBPROCESSes already allocated.

I confirmed that there are 25 connections and that this is the default. This is caused by error message 10029, SQLEDBPS, when the maximum number of simultaneously open DBPROCESS structures exceeds the current setting. I would like to increase this maximum.

I have found only two ways to do this. One is using dbsetmaxprocs using C and the other is using SqlSetMaxProcs using Visual Basic. My problem is that I am interfacing to SQL Server using a third party tool that is doing the lower level programming.

Is there some way that I can increase the maximum number of DB processes for all databases that are part of the SQL Server 7 environment, or can I set this value using a program that is called from a stored procedure?

Any ideas in this area will be greatly appreciated.

We have a production server that is configured to 100 user connections.
Without any reason, the maximum connections had been exceeded and users
can no longer access the sql. But if you sp_who , it displayed only
4 user connections. Since, I have an open connection before this error
happens, i was able to execute sp_who. This happened 4 times since we
installed the sql server. the version is 6.50.422 sp5a with hotfix.

To all gurus out there, can you give light into this problem?
