Removing Duplicate In Listbox
Apr 23, 2008
Hi There,
I am having a 1st listbox which is populating production lines, 2nd combobox to populate the production units. From here , the user will be able to select multiple production units from the combobox and hence populate the variable in listbox 3.
This is the query that I'm using to query on the variable table:
'SELECT DISTINCT PU_Id,Var_Id,Var_Desc from Variables
where PU_Id IN (@ProductionUnits)'
The problem now is that this would return all the variables for the selected production units and for those variables that have the same name, they would appear in the listbox as duplicates.
I wonder if there's any way to filter off or remove the duplicates in the listbox 3 by using sql query?
Thanks in advance for the help.

Hi all,
I have one table in which one column contains duplicate values. My question is how i can use T-SQL so that i can retrive values for all columns in the table which are distinct and retriving the single value from column which contains duplicate values.
(I know distinct)
Thanks in advance.
Minesh.

Hi,
Please give the DML to SELECT the rows avoiding the duplicate rows. Since there is a text column in the table, I couldn't use aggregate function, group by (OR) DISTINCT for processing.
Table :
create table test(col1 int, col2 text)
go
insert into test values(1, 'abc')
go
insert into test values(2, 'abc')
go
insert into test values(2, 'abc')
go
insert into test values(4, 'dbc')
go
Please advise,
Thanks,
MiraJ

I have a table that holds the following
1 7530568 87143 OESCHD 1/5/2006 6:31:58 AM
1 7530568 87143 OESCHD 1/5/2006 7:02:36 AM
for each 7530568 ordernumber there should only be one OESCHD status.
This is the query I'm using to insert the data sent to me.
INSERT INTO ORDER_EVENTS
SELECT d.division as division,
dt.orderNum as orderNum,
dt.poNum as poNum,
dt.statusCode as statusCode,
dt.statusChangeDate as statusChangeDate
FROM dt_Order_Events dt INNER JOIN
division d ON dt.division = d.divisionShort INNER JOIN
status s ON s.division = d.division AND s.statCode = dt.statusCode
WHERE directive <> 'C' AND
dt.orderNum IN (SELECT orderNum FROM ORDER_HEADER)
This works fine when used with in the hourly transactional update. But When I ran it for the Bulk UpDate (so we'd have historical data) it allowed orders to have statuses to many times.
I am not a SQL guru, I have no idea how to write a sql statement or stored proc that will remove the duplicate records. or how to change what I have to prevent further ones.
Any help would be apreciated.

Hi,
I have results from a survey in a table, every entry is assigned a unique ID. I want to remove duplicate entries based on the survey data but not on the unique ID (obviously).
So far I have...SELECT DISTINCT RespondantID, Q1, Q2, Q3, Q4, Q5, Q6, Q7, Q8, Q9, Q10, Q11, Q12, Q13
FROM Results
But that gives...
1 - Anonymous

I.e. in the above example, it would seem that 'Martin' submitted his data once and then submitted it again with his name.
How can I remove the '2 - Anonymous' frrom the data set?
Thanks!

i've to generate a notepad using this query in vb.net :
strSql = "Select count(*), d.ShareholderId, d.UsufructId, d.BnkAccount, b.SBMCode, " & _
"LTRIM(ISNULL(d.TitleCode + ' ', '')) + LTRIM(ISNULL(d.Forename + ' ', '')) + d.Surname as ShName," & _
"d.BankCode, (select count(*) from (select ShareholderId from dividend " & _
"where CompCode = 'L1' and PaymentMode = 'B' group by ShareholderId, UsufructId, " & _
[Code]....
In the select statement i need to select "d.amount" as well. When i do so, it ask me to insert it in the group by option or in an aggregate function.
Grouping by "d.amount" returns extra field as there can be 2 similar "d.shareholderId" but with different amount.
how to group the "d.amount" without having repetition in the "d.shareholderid" ??

I am trying to get people from my table that have closed accounts. However, in my table many people have more than one account. They will have multiple closed accounts and some active accounts. I need to get the people with only closed accounts.
Values in the table
Code:
name surname status Closed Number
----------- --------- ----------- ------------- ----------------------------
Jeff Burns closed 2012/01/01 142
Tina Drewmor closed 2008/05/20 546
Jeff Burns active 1900/01/01 354
Kyle Higgin active 1900/01/01 851
Tina Drewmor closed 2009/04/14 154
The query I am using so far is:
Code:
select
d.name,
d.surname,
s.status,
s.closed,
s.number
from
d d inner join s s on d.number = s.number
where
s.status = 'closed'
What I need to see in the results
Code:
name surname status Closed Number

I have regular work that requires me to extract a bunch of customer records from our database, and then remove duplicate address destinations (so we dont mail the same address more than once).
I can currently achieve this using a combination of my poor SQL skills and Excel, but it's really not working out for me, so looking for SQL wizardry necessary to do it just in SQL.
Relevant fields:
Member.AddressBarcode (This is a unique barcode (Text representation of a base-3 number) based on the customer address. So if there's more than one record in the pulled records with the same barcode, we then look at Member.MemberTypeID to determine whether to include this record in the results or discard it as a duplicate. Note that AddressBarcode may be blank if the mailing address couldn't be validated, if it is blank we don't discard it since there is no easy way to detect duplicate addresses without the barcode)
Member.MemberTypeID (This is the type of member account. We have 3 types - Single, Joint Primary, Joint Secondary, represented in this field by the numbers 1/2/3. This is also the order of preference of who to mail. So if there is a Joint Primary and Joint Secondary with the same mailing barcode, we want to discard the Joint Secondary from the results, so that the Joint Primary is the record we include in the results of who to mail.)
Member.ID (Unique numeric ID for each customer. Kind of irrelevant here, but it's a key)
So some pseudo code for what I'm trying to achieve is:
(Member.MemberTypeID = 1)
OR (Member.MemberTypeID = 2 AND Member.AddressBarcode not in results of Member.MemberTypeID = 1)
OR (Member.MemberTypeID = 3 AND Member.AddressBarcode not in results of Member.MemberTypeID = 2 AND Member.AddressBarcode not in results of Member.MemberTypeID = 1)
I suspect it requires some sort of join...

Hi All,
Below is a snippet of MS SQL inside some VB that retieves
Commodity info such as product names and related information and returns the results in an ASP Page. My problem is that with certain searches, elements returned in the synonym field repeat. For instance, on a correct search I get green, red, blue, and yellow which is correct. On another similar search with different commodity say for material, I get Plastic, Glass,Sand - Plastic, Glass,Sand - Plastic, Glass, Sand. I want to remove the repeating elements returned in this field. IOW, I just need one set of Plastic, Glass and Sand. I hope this makes sense.
Below is the SQL and the results from the returned page.
PS I tried to use distinct but with no luck I want just one of each in the example below.
Thanks in Advance!

Hi, Please help me with an SQL Query that fetches all the records from the three tables but a unique record for each forum and topicid with the maximum lastpostdate. Please provide separate solutions for SqlServer2000/2005.
I have four tables namely – Forums,Topics,Threads and Messages in SQL Server2000 (scripts for table creation and insertion of test data given at the end). Now, I have formulated a query as below :-
SELECT Forums.forumid AS ForumID,Topics.topicid AS TopicID,Topics.name AS TopicName,LastPosts.date as LastPostDate,LastPosts.author AS Author,
(select count(threadid) from Threads where Threads.topicid=Topics.topicid) as NoOfThreads
FROM Forums JOIN Topics ON Forums.forumid=Topics.forumid
LEFT OUTER JOIN
(
SELECT Topics.forumid,Threads.topicid,Messages.date,Messages.author FROM Topics
INNER JOIN Threads ON Topics.topicid = Threads.topicid
INNER JOIN Messages ON Threads.threadid=Messages.threadid
WHERE Messages.date=(SELECT MAX(date) FROM Messages WHERE Messages.threadid = Threads.threadid)
) as LastPosts
ON LastPosts.forumid = Topics.forumid AND LastPosts.topicid = Topics.topicid
Whose result set is as below:-
forumid
topicid
name
LastPostDate
author
NoOfThreads

When I use the query by using only three tables namely Forums,Topics and Threads, I get the correct result. The query is as:-
SELECT Topics.forumid AS ForumID,Forums.name AS ForumName,Topics.topicid as TopicID,Topics.name as TopicName,
LastPosts.author AS Author,LastPosts.lastpostdate AS LastPost,
(select count(threadid) from threads where Threads.topicid=Topics.topicid) as NoOfThreads

I have a stored procedure that returns a single row based on a parameter of employee ID. This particular procedure uses a CTE to traverse our org structure. One of the columns is returning a delimited string of Windows login values and due to the business rules, it can contain duplicate values. I need to have that column contain only unique values - no dupes.
For example, this one column could contain something like this:
domainuser1;domainuser2;domainuser2;domainuser 3;
The need is to convert to this:
domainuser1;domainuser2;domainuser3;
I know that's a tall order.

Hi,Say I have a table Job with columns name, date, salary . I want to getthe name ,date and salary for the date when that person earned maximumsalary. I am using something likeSELECT X.name,X.date,X.salaryFROM job XWHERE X.salary IN(SELECT MAX(Y.salary) FROM job Y where Y.name= X.name);The problem is ; if a person earns maximum salary on two dates, both ofthe dates are printed. I just want to get any one of those two rows.I triedSELECT X.name,Min(X.date),X.salaryFROM job XWHERE X.salary IN(SELECT MAX(Y.salary) FROM job Y where Y.name= X.name);but it gives error.Can anybody please suggest a solution?Regards,Aamir

I have tested the code below to remove duplicate table entries based on the field IntOOS. This code works; however, I want to ensure I am removing the oldest entries and keeping the most recent entry. The field to key on this would be something like Max(ID). What would be the best way to ensure I keep the most recent table entry?

I need write a query for removing duplicates, for Example in my table I have columns
A_ID name id
1 sam 10
2 sam 10
3 sam 10
4 sam 10
5 ccc 15
6 ccc 15
7 ccc 15
8 fff 20
9 fff 20
10 fff 20
So now I have duplicates values in id column so now I need to take only one value of each and delete the remaining. I need to take first id value 10,15,20 so only 3 rows should be there in my table.

It seems that there should be a solution for my situation, but for the life of me I can't seem to figure it out.
I need to compare two "like" tables, containing similar data. Tbl 1 is "BOOKED" (which is a snapshot of inventory) and tbl 2 is "CURRENT" (the live - working inventory table). If I write my query as follows the the subsequent result is "duplicate" data.
Code Block
SELECT booked.item, booked.bin, booked.quantity, current.bin, current.quantity
FROM BOOKED
LEFT JOIN
CURRENT
ON booked.item = current.item
No matter what type of join I use, there is duplicate data displayed for each table. For example, if there are more bins in the BOOKED table that contain a certain product then the CURRENT table will repeat data and vica versa.
As follows:
Item
Bin
Quantity
Bin
Quantity
12345
A01
500
A01
7680
12345
B01

98765
Y15
2500
Y15
3000
98765
X10
1200
Y15
3000
What I would like to do is display Bin and Quantity only once and the repeating values as NULL or [BLANK]. Or, to display all of the bins from both tables and only the quantities from each table in relation to the bin found in that table, returning a "0" if no quantity exists.
This is what I'm after:
Item
Bin
Quantity
Bin
Quantity
12345
A01
500
A01
7680
12345

Is this possible? If so, how?
I also might add that it is ok for each table to contain multiple entries for any given item. This is basically being requested as an inventory variance report - inventory before physical count and immediatly after physical count - and will only be run once a year.
-----------------------------------------------
Just thinking out loud here:
What if I created three subqueries, the first containing only BOOKED information, the second containing only CURRENT information and the third being a UNION of both tables? Something like this:
Code Block
SELECT q3.bin, q1.item, ISNULL(q1.quantity, 0) as QTY_BEFORE, ISNULL(q2.quantity, 0) as QTY_AFTER
FROM
(select item, bin, quantity
from BOOKED)q1
Left Join
(select item, bin, quantity
from CURRENT)q2
on q1.item = q2.item
Left Join
(select bin, item
from BOOKED
UNION
CURRENT)q3
on q1.item = q3.item
Order By q1.item
I don't know if I wrote the UNION statement correctly, but I will have to try this when I get back to work...
Any suggestions?

Hi everyone, having some problems
Basically, using ASP.NET 2.0 and here is my problem,
Get data from table
Put into array
Split where there is a +
remove +'s
assign to listbox to give a list of everything in that table
The + split the courses, so in my Order table I have A + B + C etc and I want all of the different options in a list box (note different records have different entries it isn't always a b c)
I am testing my code, here is what I got
Public Sub TitleChange(ByVal Sender As Object, ByVal E As EventArgs) Try Dim DBConn As SqlConnection Dim DSPageData As DataSet = New DataSet() Dim VarTxtAOE As String DBConn = New SqlConnection("Server=SD02;Initial Catalog=WhoGetsWhat;Persist Security Info=True;UID=x;Password=XXX") 'Dim DBDataAdapter As SqlDataAdapter DBDataAdapter = New SqlDataAdapter("Select AOE FROM TBL_Role WHERE Title = @ddlTitle", DBConn) DBDataAdapter.SelectCommand.Parameters.Add("@ddlTitle", SqlDbType.NVarChar) DBDataAdapter.SelectCommand.Parameters("@ddlTitle").Value = TitleDropDown.SelectedValue DBDataAdapter.Fill(DSPageData, "Courses") 'Need to find out what this rows business is about whats the number about? and am I doing it correct? 'txtAOE.Text = DSPageData.Tables("Courses").Rows(0).Item("AOE") 'txtAOE.Items.Add(New ListItem(DSPageData.Tables(0).Rows(0).Item("AOE"))) VarTxtAOE = DSPageData.Tables("Courses").Rows(0).Item("AOE") Dim VarArray() As String = VarTxtAOE.Split("+") Response.Write(VarArray()) txtAOE.DataSource = VarArray() txtAOE.DataBind() 'Response.Write(test) 'ListBox1.DataSource = test 'Response.Write(VarArray) Catch TheException As Exception lblerror.Text = "Error occurred: " & TheException.ToString() End Try End Sub My response.Write works correctly, but my list box doesn't, also I don't want to say which bit of the array like I have done using 1, I just want to display the whole array in my list box. I am not worrying about removing the +'s at the minute, just splitting my data and putting each section into a listbox
Maybe I am going about this the wrong way, but I have been trying a lot of different things and its hard to find any help
Thanks
Chris

I need to use the list of items from a multiselect listbox in a parameter of a query's IN clause.
Example:
I assemble the list from the listbox and set the paramter value so @CityList = 'London','Paris','Rome' .... etc.
A sample SQL would be:
SELECT * FROM Customers
WHERE City IN (@CityList)
However, the SQL will not work. It seems the whole string is put in
another set of single quotes by the compiler so it's treated as one
string literal instead of a list.
Is there a way around this?

Hi,
I have SQL database 2000 which has one table Sheet1, I retrieved the columns in the ListBox, then chosed some of them and moved it to ListBox2.
The past scenario worked great, and I checked the moved values, it was succesfully moved, but when I tried to copy the values in ArrayList to do a select statement it didn't worked at all.
public string str;protected void Button3_Click(object sender, EventArgs e)
{ArrayList itemsSelected = new ArrayList(); string sep = ",";
//string str;for (int i = 0; i < ListBox2.Items.Count; i++)
{if (ListBox2.Items[i].Selected)
{
itemsSelected.Add(ListBox2.Items[i].Value);
}
int itemsSelCount = itemsSelected.Count; // integer variable which holds the count of the selected items.
str = ListBox2.Items[i].Value + sep;
Response.Write(str);
}
SqlConnection SqlCon = new SqlConnection("Data Source=AJ-166DCCD87;Initial Catalog=stat_rpt;Integrated Security=True;Pooling=False");
String SQL1 = "SELECT " + str + " from Sheet1"; SqlDataAdapter Adptr = new SqlDataAdapter(SQL1, SqlCon);
SqlCommandBuilder CB = new SqlCommandBuilder(Adptr);DataTable Dt = new DataTable();
Adptr.Fill(Dt);
//return Dt;
GridView1.DataBind();
SqlCon.Close();
}
I did some changes and the new error message is
Incorrect syntax near the keyword 'from'.

Hi everyone, not sure if a this topic has been covered yet (a have been looking all day), but as I am still very new to this, my problem is as follows:
In the Try .. Catch block below, data is posted from a form and the SqlCommand.ExecuteScalar() statement returns a Unique Job ID.
I am attempting to populate a subordinate table for qualifications which are selected from a ListBox, but rather than using qualification titles, I am using the values.
My problem is that only one value (the first) gets posted multiple times, when multiple values are selected.
Looking at the For Each loop in the inner Try Catch block, I am wondering whether there is some sort of Index pointer that needs to be incremented, in order to establish new values further down the list.
I have seen no evidence that this is the case, save for the fact that the value stalls on just the first.
Any help would be appreciated.
===== CODE ===
Try
C4LConnection.Open()
JobPostingID = SqlJobPost.ExecuteScalar()Response.Write("<br />Selected Item: " & Qualifications.SelectedItem.Value)
Try
' Multiple Qualification EntriesSqlQualPost.Parameters.Add(New SqlParameter("@JobPostingID", SqlDbType.Int))
SqlQualPost.Parameters("@JobPostingID").Value = Int32.Parse(JobPostingID)SqlQualPost.Parameters.Add(New SqlParameter("@QualificationID", SqlDbType.Int))
SqlQualPost.Parameters("@QualificationID").Value = Int32.Parse(Qualifications.SelectedItem.Value)
If Qualifications.SelectedIndex > -1 ThenFor Each Item In Qualifications.Items
If Item.Selected ThenResponse.Write("<br />SelectedItem Value: " & Qualifications.SelectedItem.Text)
QualPostingID = SqlQualPost.ExecuteScalar()SqlQualPost.Parameters("@QualificationID").Value = Int32.Parse(Qualifications.SelectedItem.Value)
Response.Write("<br />Selected Item: " & Qualifications.SelectedItem.Value)
End If
Next
End IfCatch Exp As SqlException
failJobPost = True
lblError.Visible = TruelblError.Text = "Could not add qualifications <br />" & Exp.Message
End Try
failJobPost = FalseCatch Exp As SqlException
failJobPost = True
lblError.Visible = TruelblError.Text = "Error: could not post job to database <br />" & Exp.Message

I have seen some information on this but have not understood fully the answers. I am fairly new to this and have spent the afternoon trying to work on this and although I have leant some really cool things I am no nearer. How do I get selected values from a LIstbox into a SQL statement using the IN command
First I loop through a List box control to get the multi selected values: Dim li As ListItemFor Each li In lbPClass.Items If li.Selected = True Then strPC += li.Value & ", " End IfNextLabel5.Text = strPC The result in the lable looks something like: 100, 101, 102 , I get rid of the trailing blank and commar with:Label6.Text = Left(Label5.Text, Trim(Len(Label5.Text) - 2)) I have created a parameter called @PROPCLASS that will use the values from the selected values in the listbox in a SQL query using an IN statement: Cmd.Parameters.Add(New OleDbParameter("@PROPCLASS", Label6.Text)) strSQL = "SELECT * FROM web_transfer WHERE ( PROP_CLASS IN (@PROPCLASS)) AND (ACRES >= @lowSize)AND (ACRES < @HighSize) AND (YEAR = @lowYear)AND (SALE_PRICE > @lowPrice) AND (SALE_PRICE < @highPrice) "
It is really the first bit of the WHERE clause I am interested in. The sql statement works if I either type in the actual values IN( 100, 101,102) or if I select only one value in the list box. If I select two then the sql statement does not work.
My question is: How do I get the values selected in the List box into my SQL statement Thank you in advance, s

I want that the user can chose several options from one ‘listbox’, and to do this, I have created two ‘listbox’, in the first one there are the options to select, and the second one is empty. Then, in order to select the options I want the user have select one or more options from the first ‘listbox’ and then click in a link to pass the options selected to the second ‘listbox’. Thus, the valid options selected will be the text and values in the second ‘listbox’. I have seen this system in some websites, and I think it is very clear.
Well, my question is, Is it possible to insert into the database all the values from a ‘listbox’ control? In my case from the second ‘listbox’ with all the values passed from the first one? If yes, in my database table I have to create one column (field) for every possible selected option?
Thank you,
Cesar

I have a sql server database linked to my application. I have a table that I want one of the columns (Service Perfomed) to load in a list box. When I start the application nothing appears in the list box. What could I be doing wrong?
Here the code the visual studio created:
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles MyBase.Load
Me.ServiceTableAdapter.Fill(Me.MaintenanceRecordsDataSet.Service)
End Sub
I've tried combo box, text box and these seem to work fine but not the list box.
