In following SQL query: SELECT DISTINCT CodeID, CodeDesc FROM Faults.TblFltClearCodes AS TblFltClearCodes
I am getting a list but there is no null value.Within this query I would like to get only one NULL value at the top and then the list.How to do this? Explicitly I am not allowed to give a null value in the table in DB.
this is my html code [Code]....
i need to set null value to SqlDataSource Insert Parameter at runtime
i am used this code
[Code]....
what i would like to do is when the value of my sqldatasource is returned, then if it is null, run a code, in my case, redirect them to the login page, heres my code:
string connectionString = ConfigurationManager.ConnectionStrings["PokemonPlanetConnectionStrings"].ConnectionString;
string insertSql = "SELECT * FROM LoggedInUsers WHERE UserId = @UserId";
using (SqlConnection myConnection = new SqlConnection(connectionString))
[Code]....
Now what i would simply like to do is, if the select statement searches the database, and the result is not found, the simply redirect them to "register.aspx"
i have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.
At present the two datasource controls declared , render data to the page simultaneously during pageload. I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?
I have a FormView which is bound to an SQLDataSource. When a user clicks on a save button the form, I need to write any changes made to the FormView back to the table.
I have a Stored Procedure on my MSSQL 2005 database that should be executed when the user clicks on the save button.
It appears the Update is firing, but when I trap the DbCommand object in the SQLDataSource's 'Updating' event, all of the parameters that should be passed to the Stored Procedure are coming through as NULLs. Consequently, the Stored Procedure isn't updating anything.
In the click event of the save button I'm explicitly firing the SQLDataSource's Update method:
[Code]....
The parameters in the SQLDataSource <UpdateParameters></UpdateParameters> section appear to be correct.
Can anyone give me an idea on what to investigate to figure out why it appears the Update is only picking up NULLs?
I am not able to figure out why I am getting the null error at SqlDataSource10.Insert(); I tried running through break points and i checked the Insert statement and it has all the required values .. but I get error saying it cannot insert null into NrNarrativeDays.

I have a SqlDataSource connected to database and use a parametrized query to fetch out data.Query has got a very large varchar field on which i have to perform a search.To make search, i have 2 combobox and a textbox organized in this way
MAIN CATEGORY (combobox)-> CATEGORY TYPE(combobox) -> MODEL(textbox).
Based on main category choose, category type is filled from database. At last, it's added a "nothing" combobox item.Now i should search into big varchar field adding category type condition but, if nothing is specified, i should make identical search like all combobox value are selected. How should i, in your opinion, make this using SqlDataSource?
I dragged and dropped a sqldatasource and want to do an insert statement, taking the new values from a textbox. I did this already however when i do my insert statement eg. INSERT INTO Development_Programme(MHID) VALUES (@m) HOWEVER when to select the insert parameters the 'Next' button and the 'Finish' button is shaded off, I added a Select statement and the 'Next' was unshaded HOWEVER the screen to select the insert parameters is not appearing it goes straight to the Test Query.
View 3 Repliesif i do this to set the fetch parameters:
dsList.SelectParameters["client_id"].DefaultValue = Session["client_id"].ToString();
where dsList is my datasource, it works.
but wen i do the samething for the *%^&* insert, it doesnt:
dsList.InsertParameters["client_id"].DefaultValue ="1234";
it keeps saying its null, i dont understand why it woudl be doing this?

I am trying to create a stored procedure where I can insert null values in columns that have a foreign key constraint and allow nulls. The columns I am trying to insert nulls into are commentid and imageid. I have created an Insert statement in a stored procedure and I get the foreign key constraint error. Can you tell me how to allow inserting data in the other columns without having to insert anything in the commendid and the imageid?
Here is my exec of the stored procedure that is not working:

I am using Visual studio 2010 express and I have a details view databinded to an sql database table. When I use the Insert option on the view it causes an error due to it trying to insert a null into the primary key field. If the Insert function does not create a new primary key entry how is it created?

I do have a details view, which insert data to a database table using SQL Datasource. Now i need the data to be inserted in to 2 tables instead of one.
View 1 RepliesI am using 1 textbox with a Ajax Calendar extender to allow my user's to select a date graphically (exp: 12/15/2009). I have another textbox for the hour and minutes in military time(exp: 15:30). I think i have the code to grab the data from the 2 textbox's and combine them to be inserted into the field (exp: 12/15/2009 15:30). Here is my insert code for the Field:
[Code]....
However unless I make all the fields Nullable the insert fails, on top of that none of the other field that I have selected on the Detailsview Insert or Edit are inserted into there fields. Half of my fields have to be non-null values. So how do I fix this?
I can supply additional vb code and the aspx code if needed.
This is the error I'm getting: Cannot insert the value NULL into column 'Operation_type', table '/GAOSDB.MDF.dbo.BC_Perf_Log'; column does not allow nulls. INSERT fails. The statement has been terminated.'
This is the first non-null column.
I need to get this figured out because I have 30 other web pages that will be utilizing the same approach.
Conseptually what I'm doing is simple, and technically it may even be simple, but I'm still rusty. Here's what I'm trying to do:
I have a webform that allows the user to enter a new record, and in there I have also included a couple FileUpload controls. Upon clicking the "Save" button, I'm saving the details entered into one table (ITEMS), and also inserting the FileUpload details (path, id, upload_user) into another table ATTACHMNTS). Because one ITEM can have many attachments, I needed to split the tables up. So on save, I need to save the ITEM, save the ATTACHMENT, and then also put the ITEM_ID in the ATTACHMENT table. I'm second guessing myself because I think all I'd have to do is after I do the ITEM insert, do a SELECT MAX on the ITEM table and hold the newest (MAX) id in a variable and then use it in the ATTACHMENTS update. I'm not 100% on this because there IS a chance that someone else could save a few milliseconds later and I'll link the wrong ITEM. See my delima?
I have a project that I was using Access for but now find I have to change to SQL Express. Well I have no big problem with that but I now find that the SQL Statement I have been using was for OLE and does not work in SQL/Express. I am not even sure anymore if I can dump the entire CSV file in at one time? The statement I was using is below.
[Code]....
Here is my problem. What is the INSERT statement to insert a complete flat (CSV) into SQL Express? OR what method can I use to preform this task?
I have asked similiar question before where I have two control on the page header says "username" and "gender". User can select both the control or either one and the page will execute searching based on the criteria supplied. So if username supplied
SELECT * FROM [this_table] WHERE username = @username
and if gender supplied
SELECT * FROM [this_table] WHERE gender = @gender
and if both supplied
SELECT * FROM [this_table] WHERE username = @username AND gender = @gender
I know this sounds not very complicated but in my case, I am having like more than 10 controls up there. It is something likeusername, gender, age, date of brith, title, father name, frst name, last name, blur blur blur and it's a lot then I started to lost. if i were to use if else caluse on code-behind and produce query, it would end up writing a lot of if-else and if i use stored procedure (with if-else) then my stored procedure would contains a lot of if-else statement. I am fairly new to this concept and if I'm on the wrong track, please correct me. Is there any better way to save my hair without actually going through each
if-else statement to build the query ?p.s. I'm using GridView and SqlDataSource command to display the result back on .aspx page.
I am trying to check whether a username exists in my database before inserting the new row & display a message to the user if it does.
On my SqlDataSource my InsertCommand looks like this:
InsertCommand="IF NOT EXISTS (SELECT * FROM Users WHERE UserName = @UserName) BEGIN INSERT [Users] ([UserName], [FirstName], [LastName], [City], [State], [Country], [CompanyName], [Active], [PasswordHash]) VALUES (@UserName, @FirstName, @LastName, @City,
@State, @Country, @CompanyName, @Active, @PasswordHash) END"
This works as expected: If the username is unique, the row is created.
If the username already exists, the row is not added.
The problem is, if the row already exists, the insert is rejected but the user is not notified.
So my question is, is there a way I can notify the user?
Maybe something like: InsertCommand = "If Not Exists (select....) Begin Insert...Else Notify User Somehow End This is a basic database, I'm not using the built-in membership provider nor will be.
