How To Get Maximum Value In This Case?
Nov 5, 2007
Dear all,
I have a input table like this:
FieldA FieldB FieldC
------------------------------------------------
ItemA 2007-10-01 10
itemA 2007-10-10 20
ItemA 2007-10-20 30
ItemB 2007-10-05 5
ItemB 2007-10-26 9
Result :
FieldA FieldB FieldC
------------------------------------------------
ItemA 2007-10-20 30
ItemB 2007-10-26 9
How can I get such result? i.e. I want to get the record with the latest date from each item group?
thanks in advance!

I need to update many rows in some table. I've made such SQL query:
UPDATE [%TableName%]
SET [%FieldName%] = CASE
WHEN ID = 1 THEN '1'
WHEN ID =2 THEN '2'
....
END;
[%FieldName2%] = CASE
WHEN ID = 1 THEN '1'
WHEN ID = 2 THEN '2'
....
END;
WHERE ID IN {1, 2, ...}
Are there some limitations for CASE operator? How many "when - then" conditions can I include in query?

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]....

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

How can I change my T-SQL text editor from text sensitive to text insensitive?

Hello:
I have created an SQL server table in the past on a server that was all case sensative. Over time I found out that switching to a server that is not case sensative still caused my data to become case sensative. I read an article that said you should rebuild your master database then re-create your tables. So after rebuilding the master database, a basic restore would not be sufficient? I would have to go and manually re-create every single table again?
Any suggestions?

We need to install CI database on CS server, and there are some issueswith stored procedures.Database works and have CI collation (Polish_CI_AS). Server hascoresponding CS collation (Polish_CS_AS). Most queries and proceduresworks but some does not :-(We have table Customer which contains field CustomerID.Query "SELECT CUSTOMERID FROM CUSTOMER" works OK regardless ofcharacter case (we have table Customer not CUSTOMER)Following TSQL generate error message that must declare variable @id(in lowercase)DECLARE @ID INT (here @ID in uppercase)SELECT @id=CustomerID FROM Customer WHERE .... (here @id in lowercase)I know @ID is not equal to @id in CS, but database is CI and tablenames Customer and CUSTOMER both works. This does not work forvariables.I suppose it is tempdb collation problem (CS like a server collationis). I tried a property "Identifier Case Sensitivity" for myconnection, but it is read only and have value 8 (Mixed) by default -this is OK I think.DO I MISS SOMETHING ????

I have a view where I'm using a series of conditions within a CASE statement to determine a numeric shipment status for a given row. In addition, I need to bring back the corresponding status text for that shipment status code.
Previously, I had been duplicating the CASE logic for both columns, like so:
Code Block...beginning of SQL view...
shipment_status =
CASE
[logic for condition 1]
THEN 1
WHEN [logic for condition 2]
THEN 2
WHEN [logic for condition 3]
THEN 3
WHEN [logic for condition 4]
THEN 4
ELSE 0
END,
shipment_status_text =
CASE
[logic for condition 1]
THEN 'Condition 1 text'
WHEN [logic for condition 2]
THEN 'Condition 2 text'
WHEN [logic for condition 3]
THEN 'Condition 3 text'
WHEN [logic for condition 4]
THEN 'Condition 4 text'
ELSE 'Error'
END,
...remainder of SQL view...
This works, but the logic for each of the case conditions is rather long. I'd like to move away from this for easier code management, plus I imagine that this isn't the best performance-wise.
This is what I'd like to do:
Code Block
...beginning of SQL view...
shipment_status =
CASE
[logic for condition 1]
THEN 1
WHEN [logic for condition 2]
THEN 2
WHEN [logic for condition 3]
THEN 3
WHEN [logic for condition 4]
THEN 4
ELSE 0
END,
shipment_status_text =
CASE shipment_status
WHEN 1 THEN 'Condition 1 text'
WHEN 2 THEN 'Condition 2 text'
WHEN 3 THEN 'Condition 3 text'
WHEN 4 THEN 'Condition 4 text'
ELSE 'Error'
END,
...remainder of SQL view...
This runs as a query, however all of the rows now should "Error" as the value for shipment_status_text.
Is what I'm trying to do even currently possible in T-SQL? If not, do you have any other suggestions for how I can accomplish the same result?
Thanks,
Jason

I am working on a C#/asp.net web application. The application has a text box that allows a user to enter a name. The name is then saved to the database.
Before the name is saved to the database, I need to be able to check if the name already exists in the database. The problem here is that what if the name is in the database as "JoE ScMedLap" and somoene enters the name as "Joe Schmedlap" which already exists in the database,but just differs in case.
In other words how do deal with case sensitiviy issues.

After creating a blank CS database a full restore(Force restore over existing database) does change the Collation toCI. I'm unsure as to how I can restore without changing theCollation. Any suggestions?

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

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.

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 :-)

thro ADO - we are getting the rows from sql server 7.0 -- there data more than
256 characters are truncated.
How will i get the actual data ?.. where i can do the settings..?
