ADO.NET :: Checking Existence Of A Record In Sql Database Using IF EXIST And Reporting Outcome On Asp Page
I have a page that inserts a record to an sql database and I would like to do the following:

(i) Check if a record already exist before trying do an insert

(ii) If a record exist, the page should be able to inform/display a message in a textbox informing the user that the record already exist.

I have seen a number of post on the internet that suggest that one possible solution is to write a sproc and use the T-sql IF EXIST function. However, I have NOT seen a complete code showing (a) how this can be done (b) how to call the sproc from an asp page (c) and MORE IMPORTANTLY how to display a message informing a user that a record already exist i.e. when the record already exist in the database.

Javascript - Check If A File Exist In The Server?
string jSFile = ResolveUrl("~/MyProject/JavaScripts/dir/test.js");
if (!System.IO.File.Exists(jSFile))
{
...
}

This code doesn't work and I guess it's the jSFile that doesn't work well with the IO.File.Exists but I know the jSFile has a valid path because when I use few line later

Page.ClientScript.RegisterClientScriptInclude("myfile",jSFile);

it does attach the JavaScript file to the ASPX and all work fine.

How To Check A SQL Database Table To See If A Record Exists?
I have a SQL database that creates a record for every document uploaded by the user to the server. I want to check this table before a user uploads a document to ensure they don't upload a file with name that already exists.

I know how to make the connection and make the SqlCommand to query the table for an existing record. But I don't know how to check the record count from the sqlCommand I made.

Does that make sense?

Using myConnectionCheck As New SqlConnection(myConnectionStringCheck)
Dim myCommandCheck As New SqlCommand()
myCommandCheck.Connection = myConnectionCheck
myCommandCheck.CommandText = "SELECT * FROM Req_Docs WHERE Doc_Name =" & DocName
myConnectionCheck.Open()
myCommandCheck.ExecuteNonQuery()
End Using

Forms Data Controls :: Check If Data Exist In Database BEFORE Insert New Item
I have a GridView on a page for maintainance of the database (mdf). Under this GridView1 I have a FormView1 where I use the ItemInsertTemplate to Insert new rows in my database (which shows the data in GridView1). The first textbox (BIDTextBox) i have on this template, contains text which identify a person. I would like to have a routine which checks if the same value that is entered in the BIDTextBox allready exists in the database. This routine should be fired upon leaving the control BIDTextBox.

I have tried with some stored procedure in my database, but that dosn't seem to do the trick. The most logical to me seems to do a loop thru my table "Ansatte" in my database using sql, selecting any occurence from the field "BID" in my table "Ansatte" that is simillar to the text entered in the BIDTextBox.

SQL Server :: How To Check If A Record Exists In VWD?
I am very new to this and have watched a lot of the videos.  While trying out VWD2010 and SQL2008 Express, I come across many things, I just don't know how to do.  Here is the latest:

I have a Table
UserId - Int - AutoIncrement
FirstName - Var(10)
LastName - Var(10)

I also have an ASP web page that allow the user to enter a first name and last name.  It also has a button to submit. What I would like to do is have a Select statement check to see if the name already exists, then send a comment back to the user via a label.  If it doesn't exist, then I would like to Insert the info and then again inform the user via label.

SelectCommand="SELECT COUNT (UserId) FROM Users WHERE ((FirstName=@FirstName) and (LastName=@LastName))"
InsertCommand="INSERT INTO User(LastName, FirstName) VALUES (@FirstName, @LastName)"
<InsertParameters>
<asp:ControlParameter ControlID="tbFirstName" Name="FirstName"
PropertyName="Text" Type="String" />
<asp:ControlParameter ControlID="tbLastName" Name="LastName"
PropertyName="Text" Type="String" />
</InsertParameters>
<SelectParameters>
<asp:ControlParameter ControlID="tbFirstName" Name="FirstName"
PropertyName="Text" Type="String" />
<asp:ControlParameter ControlID="tbLastName" Name="LastName"
PropertyName="Text" Type="String" />
</SelectParameters>

On the code behind, I get lost. (Obviously this doesn't work, but I don't know how to go about getting a results back. Protected Sub bSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles bSubmit.Click

SqlDataSource1.Select(DataSourceSelectArguments.Empty)
(get a return)
(check return value, if <>0 then
lblResults.Text = "exists!"
else
SqlDataSource1.Insert()
lblResults.Text="added!"
end if)
End Sub

ADO.NET :: Joining 2 Tables If Record Doesn't Exist Yet?
I have a table "assignments" with records that are  assigned to multiple "users" by the "department" they belong to. Each user then can have it's own "status" for each assignment.

When the user  logs-in i need to show all his assignments and the status.(but status record doesn't exist yet)

When a new assignment is created I don't want to have to create a new record relating the assignment to the user. I want the relationship to be by the department the user belongs to and the department the assignment was assigned to.

Only thing i can think of is when the user logs in to load the assignments that belong to the user's department then look thru all the records. For each record loop thru the status table. If a record exist show the the status. if it doesn't then make default value and when the users clicks to view the assignment a new status record will be added.

Only thing i don't like is looping thru the status records while looping thru all the assignments.

How else can I do it? I don't see how could join the assignments table and the status table if the status record doesn't exist yet.

tables:
[ASSIGNMENTS]
assignmentID
departmentID
assignment
[DEPARTMENT]
departmentID
department
[USERS]
userID
departmentID
user
[STATUS]
userID
assignemntID
status

BTW, I'm using Linq-to-SQL

SQL Server :: Programmatically Store Record Into Database?
What I want to do is to store new article and for each article choose a category..

I have 3 tables for example :

1. Article table : ArticleID - int , Article - nvarchar(max) .......

2. Categories table : CategoryID - int , CategoryName - nvarchar(150)

3. Article_Categories : ArticleCategoryID - int , ArticleID - int , CategoryID - int (And I set up relation in this table...)

 I can store data into tables 1 and 2 that is working fine.. But I stuck with Table 3.

 So far my code looks like this :

 protected void Button1_Click(object sender, EventArgs e) //Add new Category (working fine)
    {
  
string connectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
        string insertSql = "INSERT INTO Categories(catname) VALUES(@catname)";

Making Checkboxes Check If They Exist In A Table?
I'm trying to make checkboxes check if they exist in a table.

What I'm initially trying to do is to list the values is a table e.g. product types, and then if a product has those types assigned to it mark the check box as checked.  e.g.

Products Table

Prod No   Prod Name

1             Silver Bag

2             Black Bag

3             Red Hat

Product_Types Table

Prod_Type_No    Prod_Type_Name

1                         Bag

2                         Leather

3                         Hat

Associated_Product_Types

Prod_No     Prod_Type_No

1                 1

1                 2

2                 1

3                3

So When I select product 1 (Silver Bag) it shows 3 check boxes for the product types and prod type 1 and 2 are checked as they exist in the Associated_Product_Types

My problem is I cant figure out how to mark them as checked based on the values in that table.

SQL Server :: Getting Last Value From Database And Check For Posts
topic - topicid (pk),sub, message (content), catid(fk), createdby, createddate, updatedby, updatedon, viewers( count of views)

post - postid(pk), topicid(fk), post (content), createdby, createddate, updatedby, updatedon.

As i told in my last post, I am designing a forums website. I am not able to design the query to retrieve the topics for a category for example say catid=1. I want to display it in a grid view as done in every forums.

I made some query :

SELECT   Topic.Sub, Topic.CreatedBy,COUNT(Topic.viewers) from topic where catid=1

group by Topic.Sub,Topic.CreatedBy

This is for retrieving the topic name from the subject and the createdby giving the topic starter and the total no. of views of that topic.

Now i want to make a query from the post table displaying the last post in the topic and if the post does not exist, i want to display the 1st post from the topic table as the last post done.

Iis6 - Application Lifecycle - How To Check Configuration Properties Exist
I've written a singleton class that exposes the web.config properties in a nice get property kind of way.

I want a Load method to parse the data in the config and set the public properties, and I want to throw exceptions (so they are logged in the EventLog) when a configuration key is missing or can't be parsed.

I tried placing the Load() code in Application_Start of the global.asax but then remembered this will only be run once, or until the application restarts.

Where is the best place to put code that you need to run 'everytime' your site is started/run by the user? I basically want the website to stop functioning if certain config properties cannot be loaded.

SQL Server :: Retrieving Data From Database - To Create A New Consultation Record For A Patient?
I'm having a question about retrieving data. I'm using VS 2008 and I have to create a new consultation record for a patient and I've already created a database with 3 tables, which are doctor, patient and consultation.

I have 10 records saved in consultation table, and I've made a aspx form which contains a DetailsView that ask for new consultation details to be added. But I have to be able to get the doctor and patient information from the database and put in the DetailsView, then fill in the rest of the consultation details. The information entered have to be written to the database in the consultation table. But I don't know how to get doctor and patient information from database and apply them into the DetailsView so that doctor who wants to add new consultation details can select patient and doctor information from the database.

I was thinking maybe I need to do a query with insert statement and apply into the DetailView,this is the query i have:

INSERT INTO [Consultation] ([ConsultationID], [GPname], [PatientFirstName], [PatientLastName], [Height], [Weight], [IllnessDescription], [Diagnosis], [Date]) VALUES (@ConsultationID, @GPname, @PatientFirstName, @PatientLastName, @Height, @Weight, @IllnessDescription,
@Diagnosis, @Date)

as you can see, I need to get the GPname, PatientFirstName and PatientLastName from the database tables and the rest will be filled in by the doctor.
