View 2 RepliesOK, I use asp.net membership and have created a new table that links together related users by use of the uniqueidentifier field as a foreign key. However, it is possible to link to a not-yet existent user (by their email) so that when that user creates an account and gets a guid, it will be updated into my table of related users and finalise the link. Trouble is, I'm trying to stop people adding the same "pending user" multiple times, so in my BLL logic I look for the entered email address for the current user and I want to check on the foreign key (the GUID field) so that I can tell the user that they've already added this user, but they haven't signed up yet (if they haven't got a foreign user key with a guid in it, they haven't signed up yet).
However, when I check the foreign key guid value (shows as null in sql enterprise manager) for null values, it never goes down the "true" logic channel... what I mean is that I've debugged it, hovered over the item I've read (it says it is system.dbnull, which it is) and yet when I do "isDBNull(myGUID.Value)" it never equates to true!
Why not?
Hi all,I have this code that I use for my Search function:SELECT DISTINCT [MUSIC_TITLE], [MUSIC_ORIGINAL_SINGER], [MUSIC_PERFORMER]FROM t_musicWHERE (@MUSIC_TITLE IS NULL OR [MUSIC_TITLE] LIKE '%' + @MUSIC_TITLE + '%') AND (@MUSIC_ARTIST IS NULL OR ([MUSIC_ORIGINAL_SINGER] LIKE '%' + @MUSIC_ARTIST + '%' OR [MUSIC_PERFORMER] LIKE '%' + @MUSIC_ARTIST + '%')) But right now if I don't enter anything in one of the textbox (2 have two, either of them can be left empty), the above Sql statement doesn't return anything since ADO.NET can't tell an empty textbox and treat it at null... So anyone please help me how to detect an empty textbox and set that to null for the above SQL statement to work. (It work in SQL Manager Studio, when I set one of the parameter = null.) I'm very new to ASP.NET stuffs, so if someone can help me to convert that function to code-behind and help me to call it from the .aspx, that would be even better as I don't want to put the code in my .aspx page... But I'm not quite there yet. Thank you all,Kenny.

The data will arrive in my SQL Server(read-only access), via replication of tables from another remote SQLServer.My application needs know when new row are inserted, or updated so it can toread this data (needs to be quick/timely so hopefully no polling) to theninterface with other remote proprietary systems.T.I.A.PS: If you can recommend appropriate books on SQL Server 2000 that wouldalso be useful.

View 7 Replies View RelatedHey. 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'

I have a column defined as smalldatetime. Default length (4), and "allow NULLS" is checked.In the Enterprise Manager UI, when i enter data into that table row, if i just tab past that column, all is well, and the value is represented in the UI as <NULL>.The problem comes once i ever enter a date into that column. Say i have entered a date (all is well), and now i want to remove that entry and go back to NULL (after the date value has been committed, different entry session, say).How is that done?It seems to me, once a date has ever been entered into that column, now, if i try to remove it, i get the error "The value you entered is not consistant with the data type or length of the column, or over grid buffer limit". I have tried deleting the value, entering spaces, entering the string NULL or the string <NULL>; maybe some other tries as well, but none works, i always get that error message and am not allowed to proceed past that cell until i restore a date value to it. I want to get back to <NULL>.Anybody know?Thank you.Tom
View 1 Replies View RelatedI'm using an ObjectDataSource in Visual Studio to retrieve records from a SQL Server 2005 database.
I have a very simple dilemma. In a table I have fields FirstName, Surname, Address1, Address2, Address3 etc. None of these are mandatory fields.
It is quite common for the user not to enter data in Address2, Address3, so the values are <null> in the SQL table.
In Visual Studio 2005 I have an aspx form where users can pass search parameters to the ObjectDataSource and the results are returned according to the passed in parameters.
The WHERE clause in my Table Adapter is:WHERE (Address1 LIKE @Address1 + '%') AND (Address2 LIKE @Address2 + '%') AND (Address3 LIKE @Address3 + '%') AND (FirstName LIKE @FirstName + '%') AND (Surname LIKE @Surname + '%')
If, for example, I simply want to search WHERE FirstName LIKE ‘R’, this does not return any results if the value of Address3 is <null>
My query is this: Could someone please show me the best way in Visual Studio 2005 to return records even if one of the Address fields is <null>.
For reference, I have tried: Address3 LIKE @Address3 + '%' OR IS NULLThis does work, however itsimply returns every instance where Address3 is <null> (accounting for about 95% of the records in the database). Thanks in advance Simon

insert into #sample (emp,data1,data2,rdate)

insert into #sample (emp,data1,data2,rdate)

I need to update the data1, data2 from yesterday or before but they should be non blank and non null and update to todays data.
It means, I can't update to 2015-03-12 values to 2015-03-13, as they are blanks or nulls.
So I need to go 2015-03-11 and check the values, if they are not blank , i need to update with todays values.

Hi Guys,
I need to detect what version/ or versions of SQL Server are installed on a machine before I can install my software. I am currently looking for SQL Server 2000 / SQL Server 2005 /SQL Server Express Edition & SQL Server 2008 CTP (for the time). How do I find this out. Is SQL-DMO the way forward or should this be some WMI script. I would appreciate any pointers/scripts etc.
I have read a lot of people mentioning using @@version from a query window but as I need the software to do this on first start up can this work for all versions
Thanks in advance
Running SQLEXPR_ADV.EXE against Windows XP SP0 causes the setup to exit gracefully with a message indicating the the right service pack is not installed.
However, running SQLEXPR_ADV.EXE against Windows XP SP1 does not exit and continues to install. Then, when you try to run a script against the installation, you get the message:
[Microsoft][ODBC SQL Server Driver][DBMSLPCN][SQL Server does not exist or access denied].
This will become very problematic when installing SQL Server Express as the database for small installations.
The setup really needs to be updated to look for all the system requirements that it can detect. Evidently it can detect the Service Packs. The Wise Installer is not able to script that requirements unless there is some way to make the Windows Installer look for it that is not documented.

I ignore the quantity of INSERT, it can be one or several. And in the values there is not any indicator that allows me to deduce if it is the last one.
It would seem that I need a trigger for COMMIT...

I am currently writing an install wizard for my web application. One of my steps is Installing asp.net membership, roles, and session state to the new database. My wizard detects if this step has already been completed through the page_Load event. Currently I am writing makeshift code just to see if the tables exist.Does ASP.Net provide a way to detect what services have been installed on the database? So far I have only found Install and uninstall functionality in the System.Web.Management Namespace.I have been searching for this for a while, I am sure this question has been answered somewhere, but there is so much base information on how to initially set up membership that I cant seem to find the answer.

I have a VB.NET program that displays the time extracted from a SQL Server database datetime datatype by way of a User-defined scalar function I created. However, sometimes information is entered into the system through the program that does not have a time-- only a date. SQL Server automatically assigns a time of 12:00 AM to these values (since they're a datetime). Is there any way to detect when this happens in my user-defined scalar function so that when I try to extract time values, I can instead return a message/time of my choice? I would rather not assume that all 12:00 AM values are automatically inserted by SQL Server since this might not actually be the case.
