I'm trying to delete some data in my database where no data is inside the field name and field id
select freelancer.id, freelancer.name FROM [bewerber].[dbo].[freelancer] WHERE freelancer.id = 'NUll' and freelancer.name = 'NUll' ORDER BY freelancer.vorname
but it seems to be wrong.
i want my query to return results where the field address is not empty or null
however, the query i have is still returning results where address is empty i.e. ' ' .
I have a sql database that on some field will have a empty string/field. I am using a Datalist to display my results. How do I not make the labels that are empty not display? Currently if the field is empty it will leave a space there which my goal is if the field is empty do not leave a white space instead move the other colunms up.
View 2 RepliesI have a table in which there is one column named "Address1"
Now in this column all the data in this displaying as follow:-
sector-2, Guj,676
Sector-4,AHD,8989
Now i want to modify all the data in this column,
if there is any "," comma found in the data,
it should delete that comma from the data?
I wanna join all the field as a new col.
but how can i ignore the empty field because i always join the field and separate by space like the following.
select (field_1+' '+field_2+' '+field_3) as new_col from TABLEA
but if the field is empty, then there is the double space
how can i ensure all the space is one space only.
I have a aspx page with a ascx control inside an ascx control and the required field validator is not hit on the action of the page.
The issue is with the 2nd nested ascx control. The field validators in the first ascx control validate correctly, but with the ascx control inside the ascx control there are issues.
The nested ascx control is a repeater control and this may be the reason, but I am unsure.
I'm not exactly sure what question to ask, but I'll list a few below.
How do I attach the field validators up a level to the 1st ascx control?
Is it possible to put required fields into a nested ascx control?
I have a listview control bound to an SqlDataSource. As part of the formatting I want to add a title to the data returned from my database. For instance if the data base returns a phone number I want to add 'Tel.' first. However I do not want to diplay this
title if the datafield is empty. Here is what I have done so far.
<ItemTemplate>
<asp:Label ID="BusinessLabel" runat="server" Text='<%# "Tel. "+Eval("Business") %>' CssClass="TeleStyle" />
Or This:Tel.
<asp:Label ID="BusinessLabel" runat="server" Text='<%# Eval("Business") %>' CssClass="TeleStyle" />
</ItemTemplate>
Business is a phone number. If the data field contains a number I get: Tel. 1234 123456. If the field is empty I get Tel. If Business is null I want nothing dsplayed, how do I do this?
When I try to edit a field of a GridView or DetailsView on the WebServer I have to highlight the area I want to edit instead of just clicking into and empty field and start typing What setting did I forget to set to allow easy editing without having to highlight the are first?
View 5 RepliesI have a SQL Server table with a number of fields that are defined with the "Float" data type. I'm running a simple query to retrieve the data from this table and use it to populate a Data Table in my C#.net application.
I just discovered that the data type of the Data Table fields is Double, not Float as I expected. As such, when I store a value like 0.157 it ends up getting stored like this: 0.15700000524520874
I'm aware that such extra "noise" occurs when such a conversion occurs. My major question has to do with why .Net didn't set the Data Type to Float (ie. Single) when the table was first populated?
I have a detailsview on my page binding a table with information about the employees. They can update their information. Some info should be visible but not updateable. I could change the update command not updating but I like the control where I can set the column to read only. In that way the employee will find the data visible and they will see that the field/column cannot be changed. But having the column read only will return a null-value into that column when editing and updating anything. Why is that? Shouldn't it just update it's read only value?

View 1 RepliesI should probably post this question to a different forum but I've had such good luck on this one, I hate to leave...I have an SQLDataSource which has a concatenated field of FirstName + ' " + LastName AS FullName. That datasource is used to populate a Primary Contact combobox in the GridView based on the dsOrganizations datasource. ComboBox datasource = dsContacts, TextField = FullName, ValueField = ContactID, ValueType = Int32
nfortunately, not all the Organizations have Primary Contacts listed yet so the above substitution breaks and doesn't even show the Primary Contacts when they existWhat I need is someway to either leave the Primary Contact row blank in the DataGrid or replace it with "[none selected]"
is both same

I have a form and stored procedure that inserts the data from the form. It works fine except that if a field isn't filled in it doesn't insert a NULL into sql it inserts "".
I've tried a few different ways but none seem to insert NULL, the one below still inserts "", can anyone point me in the right direction.
Here is the required part of the code, if you require more just let me know.
