Another table called Address with the following fields:
Id_Address
Ds_Street
I want to make the relationship between these tables so that when deleting a related field address in Person is set to null.the SQL Server allows me to make this relationship in only one field.A person can live and work in the same place. If I delete her address, I want the two Individual fields are set to null.
If I have a table with 1 or more Nullable fields and I want to make sure that when an INSERT or UPDATE occurs and one or more of these fields are left to NULL either explicitly or implicitly is there I can set these to non-null values without interfering with the INSERT or UPDATE in as far as the other fields in the table?
EXAMPLE:
CREATE TABLE dbo.MYTABLE( ID NUMERIC(18,0) IDENTITY(1,1) NOT NULL, FirstName VARCHAR(50) NULL, LastName VARCHAR(50) NULL,
[Code] ....
If an INSERT looks like any of the following what can I do to change the NULL being assigned to DateAdded to a real date, preferable the value of GetDate() at the time of the insert? I've heard of INSTEAD of Triggers but I'm not trying tto over rise the entire INSERT or update just the on (maybe 2) fields that are being left as null or explicitly set to null. The same would apply for any UPDATE where DateModified is not specified or explicitly set to NULL. I would want to change it so that DateModified is not null on any UPDATE.
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded) VALUES('John','Smith',NULL)
INSERT INTO dbo.MYTABLE( FirstName, LastName) VALUES('John','Smith')
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded) SELECT FirstName, LastName, NULL FROM MYOTHERTABLE
We have a stock code table with a description field and a brand field - when the data was entered, some of the records were entered with the brand field in the description field.
ie. Code Description Brand ABC1 BLANK DVD SONY ABC2 SONY BLANK DVD SONY
what I need to do is identify where the Brand is in the Description field ...

Using a 32-Bit SQL Server 2008 Express on my LOCAL PC. I downloaded the Advantage 8.1 OLE DB Provider and created a linked server to a REMOTE Advantage 8.1 database server. There is no data dictionary on the Advantage server.
Here is my linked server:
EXEC master.dbo.sp_addlinkedserver @server = N'1xx.1xx.xx.1xx', @srvproduct=N'Advantage', @provider=N'Advantage OLE DB Provider', @datasrc=N'1xx.1xx.xx.1xxeccET', @provstr=N'servertype=ads_local_server;tabletype=ads_cdx;'--tabletype=’ADS_ADT’ (this test works too) EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname=N'1xx.1xx.xx.1xx',@useself=N'False',@locallogin=Null,@rmtuser='adssys',@rmtpassword=Null
Testing the link succeeds with above. Using “ads_REMOTE_server” instead of “ads_local_server” and the test fails. Here is my problem, using the following queries will not work. Perhaps it’s a permissions issue? When I specify my local credentials for the remote server in the linked server it still does not work.
SELECT * FROM OPENQUERY([1xx.1xx.xx.1xx], 'SELECT * FROM ActType')
OLE DB provider "Advantage OLE DB Provider" for linked server "1xx.1xx.xx.1xx" returned message "Error 7200: AQE Error: State = HY000; NativeError = 5004; [Extended Systems][Advantage SQL][ASA] Error 5004: Either ACE could not find the specified file, or you do not have sufficient rights to access the file. Table name: ActType SELECT * FROM ActType". Msg 7321, Level 16, State 2, Line 2
An error occurred while preparing the query "SELECT * FROM ActType" for execution against OLE DB provider "Advantage OLE DB Provider" for linked server "1xx.1xx.xx.1xx".
I lost my database on my pc as I format my hard drive. Now, how I can get a copy of my ms sql server database from my hosting to work with my local pc? I need to have a local copy so that I can develop my site without internet connection. For your information, I used Hostforlife.eu hosting service. I have searched and tried many methods to do it, but no luck yet. For example, I created a backup on Hostforlife.eu and restore backup file on my pc, but nothing happens. Then I created a new database, and re-created its structure same as the one on Hostforlife, then I used the import wizard to import data from them to my pc. Again, nothing happens.
I want to remove the nulls from the result set so the result is 1 line. Code and results are below:
SELECT CustomerNumber, (case when yearseq = 2012 then isnull(sum(mainPower),0)+isnull(sum(sidePower),0)+isnull(Sum(leftPower),0) +isnull(Sum(netappPower),0)+isnull(Sum(rightPower),0)+isnull(Sum(lowerPower),0) end) as '2012', (case when yearseq = 2013 then
[Code] ....
What can I do to my code to remove the Nulls to the entire result is just 1 line?
I am stuck on a query where I need to display all the month year values even if the corresponding count_booking values are NULL. The requirement is to display the 13 month year period from current date.
For e.g. if the date exists in the current month then starting from May 15 go all the way back to Apr 14.
My current query works in terms of displaying all the 13 months if the count_booking values exist for all the months. However, if some months are missing the values then those months don't show up.how to display all the months even if the values are NULL ? Query below:
SELECT COUNT(m.BOOKING_ID) AS count_booking, LEFT(DATENAME(MONTH, m.CREATE_DT), 3) + ' ' + RIGHT('00' + CAST(YEAR(m.CREATE_DT) AS VARCHAR), 2) AS month_name FROM MG_BOOKING AS m WHERE (m.CREATE_DT >= DATEADD(m, - 13, GETDATE()))
Should data type money allow nulls? Are there valid arguments both pro and con?
Yes, there is the age-old question regarding how one might interpret a NULL found in any column - does it mean the amount is not known or that the amount is zero (in the case of a numeric type)? You get the drift...
Other than that, though - are there any practical considerations an old data hound ought to be aware of?
How to replace DateTime field with null value in SQL 2005 server I create a stored procedure aa, It works well, but sometimes I hope to replace CreateDate field with null value,I don't know how to doIt seems that datetime type is not null value create aa @CreateDate DatetimeAsUpdate cw set CreateDate=@CreateDate
I need to pass in null/blank value in the date field or declare the field as string and convert date back to string.
I tried the 2nd option but I am having trouble converting the two digits of the recordset (rs_get_msp_info(2), 1, 2))) into a four digit yr. But it will only the yr in two digits. The mfg_start_date is delcared as a string variable
option 1 I will have to declare the mfg_start_date as date but I need to send in a blank value for this variable in the stored procedure. It won't accept a null or blank value.
I have 2 databases: one for our intranet & another for our internet website.In the intranet database, we have a table called "Clients". A new client can be added in one of 2 ways:
1) One of our employees manually adds the client via the intranet 2) A new customer subscribes to our services via our website, thus becoming a new "client" (when subscribing online, we also add a record to an "Accounts" table located in our internet website database, but we'd also like to add a record to our intranet's Clients table as well).
In the client table is a field called "CreatedBy" which expects the UserId of whoever created the account. Again, this UserId can belong to either an employee via the intranet or a new customer via our internet website. how do I distinguish where the UserId in the dbo.Clients.CreatedBy field is coming from?
My 1st thought was to append a negative to the CreatedBy UserId# if it came from a customer via the website, but that just seemed too quirky (i.e. if an employee added a client and his UserId was '10', the Clients.CreatedBy would be '10'. If a customer subscribed via the website, the Clients.CreatedBy would be '-10'. Where customers can once again sign up online. So, I need a way to keep these databases separate but keep track of which db a user's coming from when we create a new Client record.
I would like to pull data from two seperate columns based on the vaule for MakeFlag. So if MakeFlag = 0 I would like the description to show but anything else I would like catalog description to show up.
I've got two databases on the same server and replicate some tables from one database to another.The replication is configured so not to drop the table if it exists, but to delete the data based on the filter if one exists. There are two tables on the subscriber that have some extra columns.
I get "field size too large" error when trying to replicate them. Is there a workaround without having to make the publisher and the subscriber tables identical by schema?
I have a table with 201 columns . I am importing 200 columns from a file using DFT. I want update the 201th column with the fileId of the file that just imported. I am storing the fileId of the file in varFileID .
How do I go back and update the 201th column ( column name sfileId) with the varFileID value?
I can use Execute SQL Task but how will I know it's the records of the files that I just imported not other rows.
We have a custom web C#/SQL2K8R2 workflow application that I need to pull Oracle data into a varchar(max) field as an XML DOM document. I have no problem pulling the Oracle data using OLEDB, but I'm not sure how to create the XML DOM doc. Once I get it into the DOM doc, I then need to assign metadata about the XML DOM doc and insert it all into a staging table:
CREATE TABLE [stg].[EtlImports]( [EtlImportId] [int] IDENTITY(1,1) NOT NULL, [EtlSource] [varchar](50) NOT NULL, [EtlType] [varchar](50) NULL, [EtlDefn] [varchar](max) NULL, --Either a SQL statement or path to file on disk [EtlData] [varchar](max) NULL, --BLOB field to hold the XML data or FILESTREAM path to file on disk [EtlDateLanded] [datetime] NOT NULL, [EtlDateProcessed] [datetime] NULL, [EtlStatus] [varchar](50) NULL, [Comments] [varchar](4000) NULL ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
I will have a separate SSIS package to pull the [XML/File] field and process the data into the workflow tables. Is there a wasy I can use the ADO Record-set Destination task to accomplish this, or do I have to create a custom C# script to create the XML DOM Doc?
Select p.Id [SenderId], p.Username, up.PhotoId, CASE WHEN mr.ReadDate is null then 1 -- New message ELSE 0 -- Message has been read END AS NewMessage, p.LastLoggedIn, p.LoggedIn
[Code] ....
The above query returns me all messages (inbox functionality) that have been sent to mr.ReceipientId, the issue I have is when I send another email to the recipient the readdate field will be null, and the other emails linked to the recipient which have also been sent via me will have a readdate date. This causes duplicate rows to appear due to the case statement, I'm trying to figure out if / how it is possible to only display the one row per conversation and set newmessage to 1 if there is an un-read message otherwise show 0 ?
I have about 100 K records of the form below in Example 1 and I would like to turn them into the form of Example 2, basically turn the entries in field2 into a coma separated list of values sorted by field1.

Hello everybody, I can't perform an operation apparently very easy: set a field to a NULL value.
This is the db: Microsoft SQL Server 2000 - 8.00.760 (Intel X86) Dec 17 2002 14:22:05 Copyright (c) 1988-2003 Microsoft Corporation Standard Edition on Windows NT 4.0 (Build 1381: Service Pack 6)
This is the table: CREATE TABLE [ProgettoTracce] ( [ID_Progetto] [int] NOT NULL , [MisDifDef] [real] NULL , [MisDifMeas] [real] NULL , [MisDifAna] [real] NULL , [MisDifID] [real] NULL , [MisDifCV] [real] NULL ) ON [PRIMARY] GO
This is qry: UPDATE ProgettoTracce SET MisDifDef = NULL WHERE ID_Progetto = 3444
The qry has been performed with no error. Then I execute SELECT * FROM ProgettoTracce WHERE ID_Progetto = 3444 and I find the value I tried to overwrite with NULL. If I update with 0 (for example) it works. Obviously this happens on the production db, because on the development db the update with NULL works fine. No transaction is called, db options are the same on dbs...
Hi!I have a table with a check constraint. But unfortunately it does notwork like I wanted.CREATE TABLE MAP([R_ID] [T_D_ID] NOT NULL,[R_ID1] [T_D_ID] NULL,CONSTRAINT CHECK_ID1 CHECK (R_ID1 = R_ID OR R_ID1 = NULL),CONSTRAINT [PK_MAP] PRIMARY KEY ([R_ID]))R_ID1 should always have the value of R_ID or NullThe following statements should cause errors:insert into map (R_ID, R_ID1)values(1,2);update map set R_ID1=3 where R_ID=1;But there occur no errors. Does anyone have an idea? It is an SQL Server2000.TIASusanne
