How would i make a select statement select the row with the nearest values? e.g.: I have 3 labels, labels1 2 and 3, with values of 1.2, 2 and 5.8 In my table i have 4 columns, first is the data im after, and the next 3 relate to the three labels. I want to select one row, where the values of labels match it the closest.......
View 8 RepliesI 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
I am having difficulty selecting data from 2 tables that do no share a primary key value. For instance, I have an actual table, a forecast table, and a GLText table. I may have an actual value but not a forecast value but I need them to appear in the same Query (like the query results shown below). I can get all values to appear in each table but have been unsuccessful in getting all values from both tables.
View 5 RepliesI want to have a default value/item of "---Select One---" and then list all of the values from the SQL statement. Currently I am having trouble doing this. I tried to add it to the List Item but it doesn't show on the page.
View 25 RepliesFor efficiency's sake I've created a number of stored procedures to run against an SQL table. Which procedure runs depends upon the checkboxlist choices a user makes before clicking a button. The checkboxlist looks something like this:
<asp:CheckBoxList AutoPostBack="True" runat="server">
<asp:ListItem Enabled="True" Value="1">Item 1</asp:ListItem>
<asp:ListItem Value="10"> Item 2</asp:ListItem>
What I can't figure out is how to loop through the checkboxes in the Button1_Click event in the .cs code behind page to add up the values of the selected items. (The value of an unclicked box being 0.) Converted to a string, the totaled value is then appended to a stored procedure name (MyPROC) for entry into the SQL statement. In other words, if the user clicks just Item 1, then the Button1_Click event would produce a stored procedure name of MyPROC1, insert it into the statement, and fire off the query; if Item 1 and Item 3 are selected, then MyPROC101 would be called.
My second question is: how do I place the concatenated string into the SQL statement?
This might all seem a bit unorthodox, but given the number of variables going into statement, it seems to this newbie the best approach.
i'm trying to to create a simple string array with data retrieved from a select statement(SELECT firstname FROM customers , for ex.)

I have two dropdown list, which is 'names' and 'types' and it's being populated by a dataset. It contains an additional item "-- ALL --" to indicate that all items of a particular field are being shown. I have an SQL select statement to filter the records according to the selected item of the dropdowns. I used a select statement to bind the records to a datagrid with regards to the selected items.
SELECT * FROM table where name = ddlnameselecteditem AND type = ddltypeselecteditem
The problem now is when I select a name from the names dropdownlist and types dropdownlist has a selection of -- ALL --, there would be no return records because there's no such thing as '-- ALL --' record in column 'types' i'm querying. I need to display rows of the selected 'name' while still showing all the 'types'. How could I achieve this? I think I need to avoid the '-- ALL --' item from the dropdownlist.

I have records in the datatable which I have retreived from xml file.
Dim docDataSet As New DataSet
Dim docReader As New XmlDocument
Dim xnl As XmlNodeList
docReader.Load("UserProfile.xml")
xnl = docReader.SelectNodes("/Users/user")
For Each xn As XmlNode In xnl
Dim xr As New XmlNodeReader(xn)
docDataSet.ReadXml(xr)
Next xn
Dim Dm_table As DataTable = ds.tables(0)
Now what I want to do is execute a select query like below:
Select * from user where userid in (select ID from Dm_table)
Retreive the records from the User table based on the ID's in the datatable.
I thought this would be easy but cannot now find out of to do it. All I want to do is execute an sql query on a table and in addition to the table's columns I want to also select/output a field that is calculated within the query. The table has a column "Owner" and I want to compare this to the UserId to produce a bool column "mine". Effectively doing:Select *, (Owner=@UserId) as mine where.....however, this doesn't work so how can I calculate a column in the select statement?
View 3 RepliesI have to pull up a list of people by their branch number which could vary, and give a detailed report on there performance using a select queries. I have the select queries but how can i create a script to look similar to this one. Ive got the branch drop downlist already created just need to know how i can go about pulling all the users in this group and doing this select to all of them. someone told me I might need to use cursors to loop thru a select with every person in the list but im not sure how to go about that.
select fldusername from tbluser where fldio='o' and
flduserbranch=@branchid
is going to give me the names of the people i need to query. but how can i run a query on each of them seperate?
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.

this might be an easy one, but I just can't get it.I am creating a page which will query a table with many columns and most items are not unique. I need to be able to get a list of records that match as many of the (up to 4) search criteria as possible.Example:am user searching for the following items, I enter at least one and up to 4 of the items below in a text box:Name, age, gender, weight (user may or may not fill in all of them).If he just enters "F" for gender, then he will get a list of thousands of females with their name, age, gender and weight.However if he enters "F" for gender and "300" for weight, he will get a much smaller list of returned records.I need to be able to create a sql statement that can perform that search with that functionality.
