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.
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.......
Dim dt As New DataTable Dim da As New SqlDataAdapter(s, c)
c.Open() if Not IsNothing(da) Then da.Fill(dt)
[code]...
When I call da.fill I am inserting all records from my query. I was then hoping to filter them to display only those where the GroupingID is equal to 0. When I run the above code. I am presented with all the data, the filter did not work. Please can you tell me how to get this working correctly.
1.LookupPageInfo and (LookupPageInfoId,pathmessageID,pagemessageID)
2.Messages (MessageId,MessageText,ChannelID)
Now i need to write a query something like this........in the query i need to pass the pathmessageid and needs to get messagetext from Messages Table,i am not sure how i need to write the below query..can someone guide me how can i write a query......as below..
select LookupPageInfoId, PathMessageID, pagemessageID, (select messagetext from Messages where MessageID=PathmessageId) as TEXT from LookupPageInfo
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'm pretty new at ASP. I've got a sheet I'm trying to modify using an IF statement. I tried putting them in, in different ways, but it either shows up in the form or I get the options multiple times
[Code]....
i have a variable picked up elsewhere strArea, so I was trying to do something like
[Code]....
I have tried putting the if's in different places, as well as case statement but usually I end up with my drop down option list as 1 1 2 1 2 3
I'm trying to pull a list of clients that have both of two codes in the code table. Here is what I have tried and it does not return any rows. I know that there are clients that have both codes.
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?
I 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.
Unfortunately, I get the following error message:Message="The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP or FOR XML is also specified."
I am using join to get values from three tables. I want the first column to be Sl.No which autoincrements by 1.What should i write in the select for the first column.
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.
Select ColA = ID ,ColB = Name ,ColC = invtotamt + (SELECT SUM(TableA.camount) FROM TableA WHERE TableA.csucceed = 1 AND TableA.cID = InventoryTotal.invID GROUP BY TableA.cID) ,ColD = ((SELECT SUM(TableA.camount) FROM TableA WHERE TableA.csucceed = 1 AND TableA.cID = InventoryTotal.invID GROUP BY TableA.cID) ,ColE = (SELECT SUM(TableB.camount) FROM TableB WHERE TableB.csucceed = 1 AND TableB.cID = InventoryTotal.invID GROUP BY TableB.cID) FROM TABLE
it look complicated, and long statement, actually it's easy, it is like: (it's a sample, not a really one)
Select ColA = ID ,ColB = Name ,ColC = ColD + ColE ,ColD = ColE + ColC ,ColE = ColC + ColD/100 FROM TABLE
it looks much easier with ALIAS. But, it seems i cannot directly use alias in select stetement like that. if i cannot use alise, i have to copy paste lots of same column definition. how can i use the alias in select statement?? this bothers me a lots of times!
