DataSource Controls :: SQL Statement - Don't Want To Return Duplicate Columns
Mar 11, 2010
I have the following simple stored procedure:
ALTER PROCEDURE GetadiByPhiNo
@PhiNo int
SELECT adirefno, adidescription
FROM aditable
WHERE adiphino = @PhiNo
Here is an example of data returned:
1 Skin diesease
2 Cough
3 Cough
4 Rash
You notice "Cough" is in the adidescription column twice. I would like to return only one row for adidescription with the same value. So what I want returned is this:
1 Skin diesease
2 Cough
4 Rash

I have a select statement in a stored procedure and want to be able to retrieve the key column value (PRODUCTID)and return it as Output when Select statement is executed on input Parameter (NAME).
addition, return two further output values (COST,TOTAL).
note the grid control expects to receive all values at once! so i need to get out these values at the same instance of execution.
Select productID,COST,QUANTITY,NAME,TOTAL,DATE
FROM PRODUCTS
WHERE NAME=@NAME

This question is for wrapping up work on a database driven AJAX AutoComplete Control that I am using to provide keyword hints to user on search pages. Each record has 6 columns for keywords where each column is for an advertiser to add a keyword. These are used in meta keywords tags, but I also want to use them for AutoComplete. The problem is that I don't know how to write a SELECT statement in Visual Studio that treats all 6 keyword columns as if they were all one column. I am looking for something like
SELECT (keyword1 + keyword2 + keyword3) AS Keywords
FROM (Merchandise)
WHERE Keywords LIKE @term
The only other thing I can think of the gain this level of functionality would be to combine them into a new table.

</asp:TableRow>
</asp:Table>
My c# code behind - I get no errors but no duplicate row
protected void Button1_Click(object sender, System.EventArgs e)
{
// Total number of rows.
int rowCnt;
// Current row count.
int rowCtr;
// Total number of cells per row (columns).
int cellCtr;
// Current cell counter
int cellCnt;
rowCnt = int.Parse(TextBox1.Text);
cellCnt = int.Parse(TextBox2.Text);
for (rowCtr = 1; rowCtr <= rowCnt; rowCtr++)
{
// Create new row and add it to the table.
TableRow tRow = new TableRow();
Table1.Rows.Add(tRow);
for (cellCtr = 1; cellCtr <= cellCnt; cellCtr++)
{
// Create a new cell and add it to the row.
TableCell tCell = new TableCell();
tCell.Text = "Row " + rowCtr + ", Cell " + cellCtr;
tRow.Cells.Add(tCell);
}
}

I have code for inserting a record into the db, it works fine from the admin part of my website but when i put it on the customer side duplicate records are inserted into the db, any ideas? I cant for the life of me see why. I have just also noticed that when i add the claim the first time it adds the duplicate entry, if i press the button again it only adds the entry once, if i refresh the page add the info again, 2 entries, click add again 1 entry?

I want to display all duplicate records in the table.My query has to fetch all the records which are duplicate(First Name or Last Name).Also I want the ability to also pull names where there might be a middle initial placed in the end of the first name field, (i.e., "Maria Z. " vs. "Maria") as well.
Table:
ID FirstName LastName
1 Zach H Hoffman
2 Zach Hoffman
3 Troy Hoffman
4 Shawn Livermore
5 Prem S
6 Jony Hoffman H

I have 5 tables as follows
as it can be seen from diagram, I have one table ie.patientdetails with Pid as primary key and other 4 tables have pid which is foreign key related to Pid in patient details.
the problem is that when if a test data is filled for say patient with Pid as 1, the data is saved nicely in required tables
If i try doing that again for same patient then a duplicate is created in test tables with pid as 1.

removing duplicate rows from datatable or (dataset) by columnd ID (unique). Below function is working but I would like to edit/adjust the remaing (former) duplicate row's value, not the ID value btw.
Example:
ID name sport
-------------------------------
356 John Football
357 Johny Hockey
357 Johny Hockey
358 mike Soccer
should be:
ID name sport
--------------------------------------------------------------
356 John Football
357 Johny newFoo Hockey
358 mike Soccer
Public Function RemoveDuplicateRows(ByVal dTable As DataTable, ByVal colName As String) As DataTable
Dim hTable As New Hashtable()
Dim duplicateList As New ArrayList()
For Each drow__1 As DataRow In dTable.Rows
If hTable.Contains(drow__1(colName)) Then
duplicateList.Add(drow__1)
Else
hTable.Add(drow__1(colName), String.Empty)
End If
Next
For Each dRow__2 As DataRow In duplicateList
dTable.Rows.Remove(dRow__2)

I need to write a sql script which will scan for records in a table (Table1) and thencopy the records found into a second table (Table2). Table2 has the same table structureas Table1Table 1 has a primary Key for the first column named CustIdI thought this would involve A simple sql statement like:
INSERT INTO Table2
FROM Table1
SELECT *
However I just realized that if A record already exists in Table2 and I try to inserta duplicate record into Table2, how should this be handled?Should I instead use an Update statement without a where clause?

Here is the deal. I need to create a Stored Procedure that has 2 SELECT statements. Now in ASP.NET, I know that a DataSet can have multiple tables and the DataAdapter can do just that. I am stuck with a scenario where I need to get a value from the first SELECT statement which will later be used in the second SELECT statement. I am creating a SP that passes one parameter (@AnswerID). Which should give me 2 resultsets. See below SELECT statements.
[Code]....
So how do I get the QuestionID from the first SELECT statement?
Basically I am creating a Questionnaire that has Question Dependacies. So from the above SQL statements I would like to display the Question Title with it's relevant answer options but depending on the previous Answer selected hence the @AnswerID parameter.
The reason why I want to use 2 SELECT statements is because I don't want to have 2 roundtrips to th server. So in my code the DataAdapter should return 2 resultsets and fill the DataSet.
If there is any another solution that can prevent 2 roundtrips to the server, I would most definitely like to know how to do it.

Here's my problem: I have an IPerson which is implemented by Employee and Student. What I really want is what you see below. One LINQ statement to get each type of IPerson. This works great until I call the method ;). It makes sense as to why I'd get the error, but I am really struggling as to find a decent way to pull all IPerson objects from the DB and avoid putting switch statements all over my application.
[code]....
Above, there is a commented out return statement - that essentially does a .ToList() and forgoes the whole deferred execution thing, creating 2 SQL statements - not ideal.
