Calculate Database Query Value By Using Math Expression?

Oct 4, 2010

I'm currently develop a monitoring and evaluation database with many indicators

For example: I have two input indicator : car , truck

Input_IndicatorID quantity
Car 3
Truck 2

I'd like to create an output indicator have field: formular. The result of vehicle = car + truck = 5

Output_indicatorID formular
Vehicle Car + truck

I don't now how to parse this string, detect parameter: car, truck to get the answer

I search on Google and find some Math parse like: muParser, bcnet but it just for a string

Access :: How To Calculate A Logical Value In SQL Query

Jan 6, 2010

In MS Access I can write a query like this (where ClassA, ClassB, etc, are boolean fields):

SELECT [ClassA] Or [ClassB] Or [ClassF] AS HasPrints, EntrySummary.EntrantID, EntrySummary.CompID, EntrySummary.ClassA, EntrySummary.ClassB, EntrySummary.ClassC, EntrySummary.ClassD, EntrySummary.ClassE, EntrySummary.ClassF
FROM EntrySummary;

However that method of deriving a calculated HasPrints value is not acceptable in ASP.NET. How can I rewrite my query in a standard SQL query format?

C# - Pass Parameters To LINQ To XML Query By Using Lambda Expression?

Aug 17, 2010

I am new to LINQ to XML in .net(C#, asp.net). I want to know more about Lambda expressions. I am using Lambada expression with the following query.

count = FieldRoot.Element("USER").Element("MM")
.Descendants("MMMS")
.Where(a => a.Attribute("ID").Value == MID)
.SelectMany(b => b.Descendants("ABC")).Count();

how the Lambda expression work specially in case of parameters (in the above case a & b) ? What is the basic concept of parameters in Lambda expression ? Can we use the names of the variables defined outside of the query instead of a & b ? which elements a & b represent in the above case represent ? Can we pass parameters from outside in the query ? If we can pass parameters from outside query then how it will be done? If you give me any other example instead of the above query to understand the concept of parameter in Lambda expression.

How To Test A Lamda Expression Variabe Query Result Is Null?.

Mar 13, 2011

var query = from emp in dbEmp.Employees join dept in dbEmp.Departments on emp.DeptID equals dept.DeptID where dept.DepartmentName.Contains(this.TextBox1.Text) select new { EmpID = emp.EmpID, EmpName = emp.EmpName, Age = emp.Age, Address = emp.Address, DeptName
= dept.DepartmentName };

if (query==null) Label1.Text = "no results match your search";

GridView1.DataSource = query; GridView1.DataBind();

Everything works in the right way, but the label doesn't show the message when query result returns null. The label can show without condition(querry==null). So how to test if a var query result returns nothing?

Databases :: Syntax Error (missing Operator) In Query Expression?

Mar 8, 2010

I have a Excel user application which has a user form (named 'Registo') that displays criteria and an image that has been entered in it's corresponding spreadsheet. This works the way it should. There's also the ability to search the spreadsheet via a form (by clicking 'Pesquisar' button) this opens a search form. However, I having a bit of a problem with it. When I try to search for something it basically doesn't do anything at all. It just sits there. So I tried to debug it and I think I'm having a problem with either the JET db engine or somethign with teh query or maybe I don't have the correct reference.

Validators - RangeValidator Can't Do Even The Most Basic Math?

Jun 3, 2010

I'm having an issue with my ASP.NET RangeValidator controls.

I want to allow users to enter a discount amount, and this amount must be negative (< $0.00). I want to verify that the amount entered in a textbox is a negative value, so I have this in my page markup:

<asp:TextBox ID="tbxDiscount" runat="server" />
<asp:RangeValidator ID="rvDiscount" runat="server" ControlToValidate="tbxDiscount"
MinimumValue="0.0" MaximumValue="0.0" EnableClientScript="true"
ErrorMessage="Please enter a negative value for a discount" />

and I attempt to set the MinimumValue dynamically in my code before the page gets rendered - to the negative equivalent of my item price. So if the item is $69, I want to set the minimum value to - $69:

rvDiscount.MinimumValue = (-1.0m * Price).ToString();

Trouble is: I keep getting this error message:

The maximum value 0.0 cannot be less
than the minimum value -69.00 for
rvDiscount

WTF?!?!??! Where I come from, -69 $ IS less than $0 ...... so what's the problem?
