select id,qty into #lastyrend from table where dt='12/31/2007'--last yr end
select id, qty into #lastmonthend from table where dt='05/31/2008' --last month end
select id, qty into #lastqtrend from table where dt='03/31/2008'--last qtr end
select id,qty into #lastweeked from table where dt='05/27/2008'
select id,#lastyrend .qty,
case when #lastmonthend.qty is null then #lastyrend .qty as lastmonthend
case when #lastmonthend.qty is null then #lastyrend .qty
when #lastqtrend .qty is null then #lastmonthend.qty .qty else #lastqtrend .qty as lastqtr
case when #lastmonthend.qty is null then #lastyrend .qty
when #lastqtrend .qty is null then #lastmonthend.qty
when #lastweeked .qty is null then #lastqtrend .qty else #lastweeked .qty as lastweekend.
from table
left join table.id=#lastyrend .id
left join table.id=#lastmonthend.id
left join table.id=#lastqtrend.id
left join table.id=#lastweeked.id
IN my query I am taking values from a table for different date series.
logic is if there is no value for a particular date then take the previous date value.
Problem
--------------
in my query #lastqtrend .qty is null but #lastweeked .qty has the value.
as per my third case statement I expected I will take the #lastweeked .qty
but since #lastqtrend .qty is null it shows the value of #lastmonthend.qty
I think here after the
case when #lastmonthend.qty is null then #lastyrend .qty
when #lastqtrend .qty is null then #lastmonthend.qty ---- after executing this line below line is not executing
when #lastweeked .qty is null then #lastqtrend .qty else
Can somebody help me how to execute this.

I am facing problems as the data in sqlserver is not case sensitive. The data in parent key may be capital/lower case and the same data in the child table may be lower/capital case. While migrating the data from sqlserver database to other databases(like oracle) its giving error as the data not found in parent key, though the data found in parent table . This is just because the case sensitive in oracle. But according to my knowledge its better if the sqlserver also supports data case sensitive.
Take a small example
Need a table to store all the alphabets in a table
the table structure is
CREATE TABLE [dbo].[ALPHABET] (
[Alphabet] [varchar] (1) NOT NULL ,
[Description] [varchar] (50) NOT NULL
)
GO
The data is
Alphabet
Description
a
Small a
b
Small b
C
Capital C
A
Capital A
sqlserver wont allow to insert data 'A' and gives error "voilation of primary key", though a & A are different according to this table.
I tried with NVARCHAR datatype also. The same problem here also. Sqlserver atleast should support data case sensitivity for NVARCHAR datatype as this can store different languages. May be in other languages the entire meaning may be differ with case differences. Even in english language some words meaning will differ with case differences. For reference can refer english dictionary

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 have a static class that makes an HTTPWebRequest to get XML data from one of our vendors. We use this as input to a stored proc in SQLServer2005. When I compile this class and call it from a console application in visual studio it executes in milliseconds, everytime. When I compile it, create the assembly and clr function and execute it in SQLServer, it takes around 14 seconds to execute the first time, then on subsequent requests it is again really fast, until I wait for 10 seconds and re-execute, once again it is slow the first time and then fast on subsequent requests. We do not see this behavior when executing outside SQLServer. Makes me think that some sort of authentication is perhaps taking place the first time the function is run in SQLServer? I have no idea how to debug this further. Anyone seen this before or have any ideas?
Here is the class:
Code Snippet
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.IO;
namespace Predict.Services
{
public static class Foo
{
public static string GetIntradayQuote(string symbol)
{
string returnQuote = "";
HttpWebRequest request = (HttpWebRequest)(WebRequest.Create("http://data.predict.com/predictws/detailed_quote.html?syms=" + symbol + "&fields=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,28,30"));
request.Timeout = 1000;
HttpWebResponse response = (HttpWebResponse)(request.GetResponse());
StreamReader streamReader = new StreamReader(response.GetResponseStream());
returnQuote = streamReader.ReadToEnd();
streamReader.Close();
response.Close();
return returnQuote;
}
}
}
When I run call it from a console app it is fine.
I compile it into a dll and then create the assembly and function as follows:
Code Snippet
drop function fnTestGetIntradayQuoteXML_SJS
go
drop assembly TestGetIntradayQuoteXML_SJS
go
create ASSEMBLY TestGetIntradayQuoteXML_SJS from 'c:DataBackupsCLRLibrariesTestGetIntradayQuote_SJS.dll' WITH PERMISSION_SET = EXTERNAL_ACCESS
go
CREATE FUNCTION fnTestGetIntradayQuoteXML_SJS(@SymbolList nvarchar(max)) RETURNS nvarchar(max) AS EXTERNAL NAME TestGetIntradayQuoteXML_SJS.[Predict.Services.Foo].GetIntraDayQuote
go
declare @testing nvarchar(max)
set @testing = dbo.fnTestGetIntradayQuoteXML_SJS('goog')
print @testing
When I execute the function as above, again, really slow the first time, then fast on subsequent calls. Could there be something wrong with the code, or some headers that need to be set differently to operate from the CLR in SQLServer?
Regards,
Skipper.

Hi experts;
I have a problem with unicode character 0x2300
I created this table
create table testunicode (Bez nchar(128))
Insert Data
insert into testunicode (Bez)values('Œ€„¢')
with 2 Unicode characters
Œ€ = 0x2300
„¢ = 0x2122
Selecting the data
select Bez from testunicode
I see
"?„¢"
„¢ = 0x2122 is ok but instead of 0x2300 there is 0x3f
When I modify the insert statement like that ( 8960 = 0x2300 )
insert into testunicode (Bez)values(NCHAR(8960)+'„¢')
and select again voila i see
"Œ€„¢"
Does anyone have an idea?
Thanks

I am trying to 'load' a copy of a SQLServer 2000 database to SQLServer 2005 Express (on another host). The copy was provided by someone else - it came to me as a MDF file only, no LDF file.
I have tried to Attach the database and it fails with a failure to load the LDF. Is there any way to bypass this issue without the LDF or do I have to have that?
The provider of the database says I can create a new database and just point to the MDF as the data source but I can't seem to find a way to do that? I am using SQL Server Management Studio Express.
Thanks!!

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 an app that uses a sqlserver 2000 jdbc driver to connect to a sqlserver 2000.
Is it possible to do a direct replacement of sqlserver 2000 with sqlserver 2005 express just by reconfiguring the app to point to the express? The app would still be using the sqlserver 2000 jdbc driver to try and make the connection.
If that is a possibility, what can be some differences in the configuration? Previously with 2000 the config information I entered is:
server name: "machinename"( or ip). I've also tried "machiname/SQLEXPRESS"
DB name: name of db instance
port: 1433(default)
user and pass.
My attempts so far results in
"java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket."
and
"java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Unable to connect. Invalid URL."

Hello,
I have an SQLServer Mobile database, and I would like to know if there is a way to upgrade it to SQLServer 2005 (.mdf) database. My database has no records in it, just the structure (tables etc).

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

Hello people.
I am in the process of planning a server upgrade to sql2005 x64.
I created 2 linked servers: one to a SQL2000 sp4 server and one to a SQL7.0 SP3.
I have the following error when I query the linked servers.
OLE DB provider "SQLNCLI" for linked server "IVDM2K" returned message "Unspecified error".
OLE DB provider "SQLNCLI" for linked server "IVDM2K" returned message "The stored procedure required to complete this operation could not be found on the server. Please contact your system administrator.".
Msg 7311, Level 16, State 2, Line 1
Cannot obtain the schema rowset "DBSCHEMA_TABLES_INFO" for OLE DB provider "SQLNCLI" for linked server "IVDM2K". The provider supports the interface, but returns a failure code when it is used.
I am aware of KB 906954.
http://support.microsoft.com/default.aspx?scid=kb;en-us;906954
I applied the instcat.sql on the SQL2000SP4 server and my linked server issues for that one are gone.
However, I ran the instcat.sql script on the SQL7.0 sp3 server and the linked server is still giving me an issue.
Can someone help me find a solution to this?

Hi,
I am new to SQL Server 2005. I tried connecting to my local machine by using my machine name as Server name and then tried running the following query:
SELECT * FROM SYS.Objects. It gives me following error:
Invalid object name 'sys.objects'.
Whereas, if I connect to my local machine using mahcinenameSQLEXPRESS, then the above mentioned query runs fine.
Why is this difference? What is the difference when I login in these 2 different ways.
Any help would be appreciated.
Thanks in advance.

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.

I have a query using Transact-SQL and it is moderately complex. I was wondering if someone could tell me if it would be better to use IF...ELSE statements or CASE, WHEN...THEN statements.
What I have is something like this...
Code:
SELECT
something something
code = CASE
WHEN something IN (A list of things)
IF something else
THEN 4
I have just though of doing IF...ELSE statements to keep it simply, but this query needs to run in a relative quick time frame. I guess my question is, is IF...ELSE faster or is it faster to use a CASE statement?
