In a new instalation of SQL Server 2005. I've made a restore from SQL Server 2000 database.
Solve some problem with the user, and it looks ok.
I'm using a asp web aplication, with vb dll, and change the sql provider from "SQL Server" to "SQL Native Client". It works, but in some recordsets the value a recive for the table primary key is null?????
If execute the querie in the database, the result has values in the primary key.

Please help, what can i do.

Using TSQL, I have a table that holds filenames of Pictures for products. Different products can be using the same picture. I need to select the filenames for a single product only if it does not exists for a different product.I have tried Where Exists (select FileName From Tbl where
Prod_Id = @var) AND NOT EXISTS(select FileName From Tbl where
Prod_Id != @var) In the Select Statement.

Hey. I need to substitute a value from a table if the input var is null. This is fine if the value coming from table is not null. But, it the table value is also null, it doesn't work. The problem I'm getting is in the isnull line which is in Dark green color because @inFileVersion is set to null explicitly and when the isnull function evaluates, value returned from DR.FileVersion is also null which is correct. I want the null=null to return true which is why i set ansi_nulls off. But it doesn't return anything. And the select statement should return something but in my case it returns null. If I comment the isnull statements in the where clause, everything works fine. Please tell me what am I doing wrong. Is it possible to do this without setting the ansi_nulls to off??? Thank you
set ansi_nulls off
go
declare
@inFileName VARCHAR (100),
@inFileSize INT,
@Id int,
@inlanguageid INT,
@inFileVersion VARCHAR (100),
@ExeState int
set @inFileName = 'A0006337.EXE'
set @inFileSize = 28796
set @Id= 1
set @inlanguageid =null
set @inFileVersion =NULL
set @ExeState =0
select Dr.StateID from table1 dR
where
DR.[FileName] = @inFileName
AND DR.FileSize =@inFileSize
AND DR.FileVersion = isnull(@inFileVersion,DR.FileVersion)
AND DR.languageid = isnull(@inlanguageid,null)
AND DR.[ID]= @ID
)
go
set ansi_nulls on

Im trying to add a record to the DB and then get the primary key for that record. Im doing this but is obviously wrong....
Code:
// set the prepared statement
String sql="INSERT INTO Client(username, country, clientIP, browser, os) VALUES(?,?,?,?,?)";
PreparedStatement pstmt = conn.prepareStatement(sql);
pstmt.setString(1, inUserName);
pstmt.setString(2, inCountry);
pstmt.setString(3, inClientIP);
pstmt.setString(4, inBrowser);
pstmt.setString(5, inOS);
// Insert the row
pstmt.executeUpdate();
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT SCOPE_IDENTITY()");
System.out.println("Result "+rs);
Any advice??

Dear all,
I would like to use SSIS to populate product information from a remote database to a local one.
There are Product table (which contains the basic information) and ProductImage table(which contains the product images in binary).
I would like to use a join query
SELECT A.name, A.price, B.image from Product A INNER JOIN ProductImage B WHERE A.ProductImageID = B.ProductImageID
to return all the product information from the remote database.
When populating the local database, the local ProductImage table will be populated first and then the local Product table will be populated with the ProductName, ProductPrice return from the query together with the newly genetated ProductImageID afer insert a record into the local productimage table.
The ProductImageID column is set as the identity column in the ProductImage table.
I am very new to SSIS. Is there a way to handle this scenario? What components do I need to use?
Thanks

Hi,
As I try to do an insert using an stored procdure I get an error reading...
"Cannot insert the value NULL into column 'cgpID', table 'AdminDB.dbo.CurrentGroup'; column does not allow nulls. INSERT fails."
What is wrong? cgpID is the primary key of the table CurrentGroup. It is the first field in the insert statement below and it is set to @@identity in the Values statement.
Thanks in advance!
ALTER PROCEDURE [dbo].[insert_currentgroup]
(
@cgpActivityGroupID nvarchar(30),
@cgpPreRegistredFrom nvarchar(30),
@cgpRegistredFrom nvarchar(30),
@cgpRegistredTo nvarchar(30),
@cgpMaximalNumber nvarchar(30),
@cgpStartDate nvarchar(40)
)
AS
SET Identity_insert [dbo].[CurrentGroup] ON
INSERT INTO dbo.CurrentGroup( cgpID, cgpActivityGroupID, cgpPreRegistredFrom, cgpRegistredFrom, cgpRegistredTo, cmrID, cgpMaximalNumber, cgpStartDate)
VALUES (@@identity, @cgpActivityGroupID, @cgpPreRegistredFrom, @cgpRegistredFrom, @cgpRegistredTo, 1, @cgpMaximalNumber, @cgpStartDate)
SET Identity_insert [dbo].[CurrentGroup] OFF

I have a table with multiple products from different suppliers. there will duplicate products in my db as Supplier A may stock the same product as Supplier B. I have a business rule that only one unique product can be online at one time and as such I want the cheapest product from the 2 Suppliers to be displayed where there is a match.
I have been trying a Group By clause and also a partition by but my problem is returning the primary key for the winning row (minimum price).
here is an example
CREATE TABLE #TempTable(
productcode nvarchar(50),
productname varchar(50),
productmanufacturer varchar(50),
saleprice money,
tyrewidth varchar(5),
[Code] ....
How can I return the productcode in the above query for the row with the cheapest price? If I try MIN(productcode) or MAX(productcode) it will not always return the product code associated to the min price.

I have a query that returns contacts connected to a client, but the problem is that it's only returning a result when a contact is associated with a client, even if the client does exist in the db. i want it to still return the client if the client exists.
SELECT * FROM clients, addressbook where clients.clientid = addressbook.clientid AND (clients.clientname LIKE '" . strtoupper($_GET['txtfname'])."%')

I am inserting a record into a table that automatically generatesunique ids (i.e. Primary Key). Is there anyway to return this id. As Iam using this on ASP.net page and I really need the ID to update thepage with the new details.I think on mysql there is something called LAST_INSERT_ID which doesthis.

Hi,
I am making a program in Visual Basic .NET with SQL Server 2000.
I have a table "MyTable" with a primary key named "Id". The primary key is 'Create Unique' checked and 'Index' selected. When I insert all the fields required, except "Id" of course, I need the new record's "Id" in my VisualBasic program, but I don't know how...
I must do one of them, but don't know how either of them:
-Create a trigger on insertion that will send to the user that sended the insert command the "Id" of the record just created.
or
-get the command in Visual Basic that will send the Insert command with a return field ("Id")
Thanks in advance,

I am update/inserting records threw a web form in vb.net. I need to insert 'NULL' into my microsoft sql server database. I am not talking about the below line of code where website is the name of my paramater. If i do that it will just place a blank into that field in the database. If i dont enter anything into that textbox I want it to to say NULL in that field. So if I go into the actual table in the SQL Server Management Studio and look at the website field of the recored I just added or updated and did not type anything into the web site textbox it needs to say NULL. I also tried the second line of code but that places a single quote in front and behind NULL. So the field will have the value 'NULL'.
website.value = txtwebsite.text.tostirng
if txtwebsite.text ="" then
website.value ="NULL"
end if
The reason why I need the NULL there is because I bind the website filed to a hyperlink template in a gridview. The actual text of the hyperlink is bound to PAYER which is a name of a insurance payer but the navigateto is bound to the website field. If i do not enter any data into the website field and it stays as NULL, then when my gridview is loaded, payers that dont have a website will not be underlined and user wont have the option to click on them since there is no value for the navigateto. But if i use my form to update/add a payer and leave the website textbox blank in puts a blank into that field in my database and when it loads that new row into the gridview the PAYER is underlined and u can click on it but it will just take u to the web site is unavailable page. So is there anyway to actaull have NULL placed into a filed and not just blank space

I am working on a web application for a company that uses an existing company database. I just found out before the long weekend that a couple hundred of the items in the table aren't completely related.
I am mostly using 2 tables for the project: ItemVersion, ItemVersionRev
ItemVersion has fields: ItemVersion, ItemNumber, RecordID
ItemVersionRev has fields: RecordID, RevNumber
All of the items in the database have ItemNumbers (obviously) and most have revision numbers (RevNumber). One of the functions that I created for my application finds the MaxOfRevNumber. I ran a query on the database and saw that dreaded error screen that read "There is no row at position 0"
The query that I have now simply returns MaxOfRevNumber. Is there a way to program a query to check and see if an ItemNumber has a Revision and depending on the result, return a certain value. For example, if there is not a corresponding RevNumber, then return 0 as the RevNumber?

Hello all
I am trying to run a sql statement, (without having to run stored procedures), that will lookup a value stored in a Record.field., otherwise ignore the value if it is blank. I have a field tied to a Microsoft Access form - ItemLocation. If the user selects a unique ItemLocation the report will attempt to locate all values within that ItemLocation. If the user decides to leave the field blank, I would like for it to return all values for every ItemLocation. If anyone can help, I would really appreciate it. I will attach code. My problem is the last line of this SQL statement. If F.ITemLocation is null, I get no data. I would like for it to return everything. Thank you.
Code:
SELECT DISTINCT
B.BarCodeID,
A.ItemDescription,
A.ItemCategory,
A.TypeOfItem,
A.SerialNumber,
B.ItemLocation,
B.LocationID,
B.LastUpdate,
B.TrackItID,
B.UserID
FROM
tblMISFixedAssetTable A,
tblMISFixedAssetTable2 B
WHERE A.BarCodeID = B.BarCodeID
AND A.DisposalDate is null
AND B.LastUpdate = (Select Max(C.LastUpdate)
from tblMISFixedAssetTable2 C
Where B.BarCodeID = C.BarCodeID)
AND B.BarCodeID in (Select D.BarCodeID
from tblMISFixedAssetTable3 D
Where D.FiscalYear = (Select E.FiscalYear
from tblReportFY E))
AND B.ItemLocation = (Select F.ItemLocation
from tblReportFY F)

I have a case where a table has two candidate primary keys,but either (but not both) may be NULL. I don't want to storea copy of the concatenated ISNULL'ed fields as an additionalcolumn, though that would work if necessary. Instead, I triedthe following (this is a related simplified example, not myreal one):CREATE FUNCTION ApplyActionPK(@IP int = NULL,@DNS varchar(64) = NULL)RETURNS varchar(74) -- NOT NULLASBEGINdeclare @val varchar(74)set @val = str(ISNULL(@IP, 0), 10)set @val = @val + ISNULL(@DNS, '')return @val-- Also tried "return str(ISNULL(@IP, 0), 10)+ISNULL(@DNS, '')"-- Also tried "return ISNULL(STR(@IP, 10), ISNULL(@DNS, ''))"-- ... and other things...ENDGOcreate table ApplyAction(-- An action applies to a computerAct varchar(16) NOT NULL,-- The action to applyIP int NULL,-- The computer IP address, orDNS varchar(64) NULL,-- The DNS name of the computerTarget as dbo.ApplyActionPK(ComputerID, DNS), -- PK value-- Also tried "Target as ISNULL(STR(@IP, 10), ISNULL(@DNS, ''))"CONSTRAINT PK_ApplyAction PRIMARY KEY(Act, Target))SQL Server always complains that the primary key constraint cannot becreated over a nullable field - even though in no case will the 'Target'field be NULL.Please don't explain that I should store an IP address as a string.Though that would suffice for this example, it doesn't solve myactual problem (where there are four nullable fields, two of whichare FKs into other tables).What's the reason for SQL Server deciding that the value is NULLable?What's the usual way of handling such alternate PKs?Clifford Heath.

I have this program that I want to invoke from SQLServer funny thing is I can invoke this from command line but could not get it to work via 'xp_cmdshell' on this particular server. When I invoke run the following from SQLServer Query Analyser I always get 'NULL' returned.
I tried just running EXEC master..xp_cmdshell 'dir ' and it worked, so I am certain it is not a SQL rights problem.
FYI, I executed the same code on another machine and it worked. I just cannot figure out why it is not working on this one server?
Can anyone help? thanks

Hi,
I have this problem with MS SQL Server.
I have this table 'Request' in which there's 2 fields 'RequestName' and 'DateSubmitted'.
The datatype for 'DateSubmitted' is datetimn.
I have to write a query to extract all the 'RequestName' that falls under each month based on the 'DateSubmitted'.
For example, the table 'Request' has 12 rows, each row ('DateSubmitted') with the month of the year. Like row1 = January, row2 = February etc.
For each month, I have to extract all the 'RequestName' for that month based on 'DateSubmitted' field.
My query is like this:
select RequestName, datename(month, DateSubmitted)as month
from Request where datename(month, DateSubmitted) = 'March'.
By right it should return just one row right?
Instead, it returned me all 12 rows, only one row with value 'March' and the other 11 rows with value 'NULL'. Even if the other 11 rows have value of other months, when i run the above query, it will return me null.
Any help is appreciated.
thanks a million.

I am trying to return all the names of employees and their managers
this query returns all the employees except for 1
SELECT E.FNAME,E.LNAME,M.FNAME,M.LNAME
FROM EMPLOYEE E,EMPLOYEE M
WHERE E.SUPERSSN=M.SSN
the one that isn't returned has a null SUPERSSN, but when I add in:
OR E.SUPERSSN IS NULL
it returns a row with the name of the employee whose SUPERSSN is null 8 times (where each time the M.FNAME,M.LNAME are other employee names)
How do I ammend the first query to return each employee and their respective manager once, the employee without a manager having null values for the manager name columns?

SQL Server 2000 SP3.Is it possible for the @@ROWCOUNT function to return NULL after astatement? I am troubleshooting a relatively large stored procedure withmultiple SELECT statements and a couple of INSERTs into table variables.Immediately after each statement I save the value returned by @@ROWCOUNT toa local variable. That information eventually is passed back to the clientvia one output parameter, for all statements in the procedure.Occasionally, the value returned via that parameter is NULL. This cannot bereproduced by re-running the SP with the same input parameters.Before doing any further troubleshooting, I would like to rule out thepossibility that @@ROWCOUNT can actually return a NULL under somecircumstances. From searching the archives, it appears that in SQL Server7.0 this could happen in the context of a DML query on a table withtriggers. This is not the case here - the only DML queries are INSERTs intotable variables, all other queries in the SP are SELECTs.Any related information would be appreciated.--remove a 9 to reply by email

I'm using a Merge statement to update/insert values into a table. The Source is not a table, but the parameters from a Powershell script. I am not using the Primary Key to match on, but rather the Computer Name (FullComputerName).
I am looking on how-to return the Primary Key (ComputerPKID) of an updated record as "chained" scripts will require a Primary Key, new or used.As an aside: the code below does return the newly generated Primary Key of an Inserted record.
CREATE PROCEDURE [dbo].[usp_ComputerInformation_UPSERT](
@FullComputerName varChar(50) = NULL

I'm trying to ensure that only of the parameters is passed to my stored procedure.
BOL says that the IS [NOT] NULL operator (language construct?) will return a boolean. An IF statement takes an expression which results in a boolean so I was surprised to find that the below code doesn't parse.
CREATE PROC sp_OneParm(
@NumericVal float = null,
@StringVal nvarchar(200) = null,
@DateVal datetime = null,
@BitVal bit = null)
AS
DECLARE @ValCount tinyint
SET @ValCount = 0
-- Ensure we've only got one update value specified
IF @NumericVal IS NOT NULL @ValCount = @ValCount + 1
IF @StringVal IS NOT NULL @ValCount = @ValCount + 1
IF @DateVal IS NOT NULL @ValCount = @ValCount + 1
IF @BitVal IS NOT NULL @ValCount = @ValCount + 1
IF @ValCount > 1 RAISERROR ('Only one @*Val paramater may be specified when calling sp_OneParm()', 16, 1)
-- Other Stuff
GO
Am I missing something simple or do I need to restructure my code to achieve the logic I want?
