I am using VS 2010, SQL 2008 express and doing windows applicaion programming in vb.net.I want to write a select query(or Stored Procedure) such that the conditions mentioned under WHERE clause can be variable .like :Select * from TABLE where F1 = var1 and F2 = var2 and F3 = var3.Now on the basis of some conditons the equations in where clause should beused.Say condition is variable value >6.Now in this case ,if
var1 =7 var2 =3 var3 = 8 then the query shud behave like
:
select * from TABLE where F1 = var1 and F3 = var3

how to select multiple table in vb2010? i trying to create a login so i need to retrieve the data in 3 different tables in one database i have a code but not work.[code]
View 2 RepliesOk, the basic situation: Due to a few mixed up starts, a project ends up with not one, but three separate databases, each containing a portion of the overall project data. All three databases are the same, it's just that, say 10% of the project was run into the first, then a new DB was made due to a code update and 15% of the project was run into the new one, then another code change required another new database for the rest of the project. Again, the pertinent tables are all exactly the same across all three databases.
Now, assume I wanted to take all three of those databases - bearing in mind that they can't just be compiled into a single databases due to Primary Key issues and so on - and run a single query that would look through all three of them, select a given set of data from each, then compile those three sets into one single result and return it to the reporting page I'm working on.
The following code is looking for the phone number of contacts in a database when the column "hoohoo" = 15. However it doesnt keep to this condition, but displays all of the numbers. Am i missing a line that tells it to keep to the condition???
Dim SQL As String = "SELECT *, Phone FROM TblContacts WHERE Hoodoo=15"
Dim myOleDbCommand As New OleDb.OleDbCommand(SQL, con)
con.Open()

How would I perform this SQL query
Select Distinct s.*
from #ScopeIDs x
Join Scopes s on s.ScopeID=x.ScopeID or x.ScopeID is null
in LINQ to SQL? (This query would return all Scopes whose ScopeID is present in #ScopeIDs, unless one of the entries in #ScopeIDs is null, in which case it returns all Scopes).
A "literal" translation doesn't work, since LINQ doesn't support joining with multiple conditions - code along these lines ...
From x in ScopeIDs
Join s in Scopes on s.ScopeID equals x.ScopeID or x.ScopeID equals nothing
Distinct Select s
... doesn't compile.
How can I have multiple If Not conditions on one line?

I have two tables 1) tblRequests and 2.) tblMainTags. The Fields in tblRequests are Tag_Request_No, Employee_ID , Accepted, Accepted_Date, and Accepted_Time. The Fields in tblMaintags are Tag_Request_No, Tag_ID, Completed, ... The fields 'Accepted' and 'Completed' are set to YES/NO.
[Code]...
I currently have an If...Then statement that checks if all fields of a form have been filled before saving the info in a file. I'd like to be able to tell which field has not been filled to give the user a dynamic message (at the moment, it only tells them that the checklist is not completed ) :
If (txtNoDemande.TextLength = 8 _
Or txtNoDemande.TextLength = 13 _

I have the following:
myFilteredContractors = (From c In myFilteredContractors
Join cc In myConClasses On c.ContractorId Equals cc.ContractorId
Where inClassifications.Contains(cc.ClassificationId)[code].....
This is properly ordering this list of contractors by the number of classifications that they have.I also want to order them by whether or not they have a field set (CompanyOverview), which if is an empty string should be below those contractors who have set their CompanyOverview. Also, after the CompanyOverview is ordered I want to order by Registration Date.So it should order by:
Number of Classifications
Whether Overview has been set (c.CompanyOverview)
Registration Date (c.AppliedDate)
Is it possible to all of this in LINQ?
I am trying to write a Function which will return a data table, filled with a data from a database.
The Function will accept 6 diffrenet parameters as Optional. Each one of them will be an additional condition to be added to a where clause, if it`s provided when the function is beeing called.
Is there any method in .NET to simply add a new condition to the where clause?
I have a form that contains multiple conditional or if statements on several defferent for controls.
Example: Radio Buttons, TextBoxes and CheckBoxes.
I am intending to create an order form(demo) where the user can select multiple products.
I have a default order number that changes by one everytime an order is successful.
An order is only successful if all the information on the form is entered correctly.
My question is where do I insert the code for the order number?
Basically for the order number I have a counter that count by increment of one if an order is successful.
Meaning when the user hit place order, and all the infromation is right, then the order numer goes to 1 from zero.
Where do I add the condition for the order number since all the fields must first be completed.
Do I have to create a whole line of if else statements?

I have a question regarding the dataset usage in Reporting Services. I have a stored procedure which returns multiple select statements (result tables), and I created a Dataset in Reporting Services 2005 with this stored procedure. The problem is that I can not reference the second or third result table, and I can only use the first select statement fields. Is this the limitation on Reporting Services Dataset or is there a way to use multiple table results in one dataset?

I have pulled information from a database into a datatable (dtCustomerInfo) then I expanded on the columns by processing the data and I can display this in a datagridview without any problem. However, the data is in detail and I want to ultimately summarize by customer name.The code below has a commented sql statement that is the statement I ultimately want but it is not working. However, the idea is that I want to Select from one datatable into another but run aggregate sum on several columns so that I will get one record per customer showing totals for each column.So I broke it down to just pull all data possible into the second table.[code]I do know the grouping in the current select * statement does nothing but my issue is more that the columns do not show up.
