I am trying to get the minimum and maximum values from a field in SQL Server 2008 Express, but I cannot even get started because I keep getting this error that I cannot figure out.
View 6 RepliesHallo 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 :-)

Table definition:
Create table code (
id identity(1,1)
code
parentcode
internalreference)
There are other columns but I have omitted them for clarity.
The clustered index is on the ID.
There are indexes on the code, parentcode and internalreference columns.
The problem is the table stores a parentcode with an internalreference and around 2000 codes which are children of the parentcode. I realise the table is very badly designed, but the company love orms!!
Example:
ID| Code| ParentCode| InternalReference|
1 | M111| NULL | 1|
2 | AAA | M111 | 2|
3 | .... | .... | ....|
4 | AAB | M111 | 2000|
5 | M222 | NULL | 2001|
6 | ZZZ | M222 | 2002|
7 | .... | .... | .... |
8 | ZZA | M222 | 4000|
The table currently holds around 300 millions rows.
The application does the following two queries to find the first internalreference of a code and the last internal refernce of a code:
--Find first internalrefernce
SELECT TOP 1 ID, InternalReference
FROM code
WHERE ParentCode = 'M222'
Order By InternalReference
-- Find last ineternalreference
SELECT TOP 1 ID, InternalReference
FROM code
WHERE ParentCode = 'M222'
Order By InternalReference DESC
These queries are running for a very long time, only because of the sort. If I run the query without the sort, then they return the results instantly, but obviously this doesn't find the first and last internalreference for a parentCode.
I realize the best way to fix this is to redesign the table, but I cannot do that at this time.
Is there a better way to do this so that two queries which individually run very slowly, can be combined into one that is more efficient?
I have a report that calculates mean, min, max, stddev of somer exercises for a class (pushups, situps, trunk lifts, etc). I also have to calculate those for the 1-mile run time (ex: data -- 7:56, 6:35, 9:45 ( in minuteseconds). Obviously the standard Avg(), Min(), Max(), StdDev() functions won't work for time. So I put in some custom code to convert the time to seconds so I can use the standard functions on the seconds and also code to convert that answer back to minuteseconds. Max() works, but for example when I try to calculate the min(), it includes nulls from the dataset as zeros (not every student has to do the mile run). So the min is always 0. How can I exclude nulls from being calculated. The min() function excludes nulls so it returns the correct min() on integer data. What else can I do?

If so, you might wanttotry the following alternative (using CURRENT_TIMESTAMP as example;replaceit with your date column / parameter):SELECT CAST(CONVERT(varchar, CURRENT_TIMESTAMP, 112) AS int)You could put this in the UDF (probably at least as fast as yourcurrentCalenmdar-table based function), or use it inline as a replacement tothefunction call (probably even faster).It should work for all dates from Jan 1st 1753 through Dec 31st 9999.Best, Hugo--(Remove _NO_ and _SPAM_ to get my e-mail address)

Hello,I need to select the minimum between the result of a function and anumber, but i can't find a smart way.

View 4 Replies View RelatedMy sql gives me the results as shown in #TEMTAB Table.some times Mitem_id is repeated for the same Group_id,SGroup_id with different item_id

Minimum Date in DateStamp field is not 1-Jan-100. Wouldn't we expect that.
In SQLServer2000 is it "1-Jan-100", if not WHY ??,
In the previous versions it is "01-Jan-1753"

This has me stumped.
I have a table UnitRateItems with the following columns
ItemID, Description
and table UnitRates with the following columns
ItemID,Year,UnitRate
UnitRateItems and UnitRates have a primary-foreign key relationship on ItemID.
In UnitRates, there may be several rows with the same value for ItemID but a different value for Year. What I want to do is pick the row with the largest value of Year for a given ItemID. I want to do this for ALL the rows in the table (not just for a particular ItemID).
In other words, I want to return one row in UnitRates for each row in UnitRateItems. I want that one row to be the one with the highest Year for that ItemID.
It sounds simple, but I can't seem to figure out how to do it. The MAX function only works on a single column. I can get the MAX Year, but then I can't tell it "pick up the other values that go with the row with the MAX Year".
Any help would be greatly appreciated!

Here's a portion of the current statement.
UPDATE EngagementAuditAreas
SET numDeterminationLevelTypeId = parent.numDeterminationLevelTypeId,
numInherentRiskID = parent.numInherentRiskID,
numControlRiskID = parent.numControlRiskID,
numCombinedRiskID = parent.numCombinedRiskID,
numApproachTypeId = parent.numApproachTypeId,
bInherentRiskIsAffirmed = 0,
bControlRiskIsAffirmed = 0,
bCombinedRiskIsAffirmed = 0,
bApproachTypeIsAffirmed = 0,
bCommentsIsAffirmed = 0
FROM EngagementAuditAreas WITH(NOLOCK) ...
And what I need is to conditionalize the values of the "IsAffirmed" fields by looking at their corresponding "num" fields. Something like this (which doesn't work).
UPDATE EngagementAuditAreas
SET numDeterminationLevelTypeId = parent.numDeterminationLevelTypeId,
numInherentRiskID = parent.numInherentRiskID,
numControlRiskID = parent.numControlRiskID,
numCombinedRiskID = parent.numCombinedRiskID,
numApproachTypeId = parent.numApproachTypeId,
bInherentRiskIsAffirmed = (numInherentRiskID IS NULL),
bControlRiskIsAffirmed = (numControlRiskID IS NULL),
bCombinedRiskIsAffirmed = (numCombinedRiskID IS NULL),
bApproachTypeIsAffirmed = (numApproachTypeID IS NULL),
bCommentsIsAffirmed = (parent.txtComments IS NULL)
FROM EngagementAuditAreas WITH(NOLOCK)

Does the IDENTITY field type in SQL have a maximum size to it?
You know like int only goes so high up,
Can any one help me, i'm building a dynamic database driven site using dreamweaver and MS SQL2000 andi'm haveing problem storing over 8000 characters in a table filed (IE: it wont let me!!) is there a special table field value that i need to set to get more characters in a table field or is this a limitation of SQL.
Any help or suggestions would be appreciated

Hi All,
Is there a way to check the data type and the maximum length of a field?
I have a problem selecting maximum values inside a data flow, when the field is varchar. For example, I could have an incoming text file with following rows (the real life problem is a bit more complicated, but the idea is the same)
ID Desc
1 Car
1 Truck
1 Bicycle
2 Horse
2 Cow
Now I would like to group by ID, and have the maximum value from the Desc field, resulting
ID Desc
1 Truck
2 Horse
I tried to sort the data flow first with ID ascending and Desc descending, followed by sort with ID ascending and "Remove duplicate sort values" turned on. However, the sort does not seem to select the first Desc value it gets, because the result is.
ID Desc
1 Bicycle
2 Horse
If you have any hints, how to tackle this problem, please help!
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.

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

I have a table "abc" with there fields of same data type 'x','y','z'.
'x' is the primary key for the table 'abc', what I supposed to do is to copy the values under field 'y' to field 'z' irrespective of the values already with 'z'.

Hi,
In Microsft Access you can use the value of fields in calculations eg, txtbox_demand_value * qty - is this possible in Reporting Services????
I am trying to replace field values in SSIS. For exapmle, I have 'unkown' and 'N/A', and a few other values that mean the same thing, and I want to give all these fields the same value. I have not been able to find a tool in the toolbox to make this type of change. Is there one? And, if there is, do you know a link to a page explaining its use?
The closest I have come is the Derived column String Transformation:Replace. But, I have not been able to get this to do what I want. If you know of a good reference explaining this tool's use I'd appreciate it.

My problem is that this returns individual row results and are displayed on individual lines. Where the object_id is the same i want all the textual info to be displayed within the same row.
Does anyone know how i can accomplish this?
