Implementing a search function

Hey guys, im trying to implement a search function to my booking program, wich retrieves data from a SQL database. I have the screan all set up and all the variables at the ready, the only problem is, im not sure how to execute it in a sqlcommand line.

I've got all the fields that are required, such as date, time but i also have two optional options, Room Type and Room Capacity.

How would i write a sqlcommand to search for available rooms that meet the criteria for the room to be booked?

Heres the code i have so far;

Code:

---

    'Declare Variables
        Dim sRoomType As String = CStr(cbRoomType.SelectedItem)
        Dim iRoomCap As Integer = CInt(cbRoomCap.SelectedItem)
        Dim dStartDate As Date = McDateRequired.SelectionRange.Start
        Dim arr1 = cbStartTime.Text.Split(":"c)
        Dim arr2 = cbEndTime.Text.Split(":"c)
        Dim dStartTime As Date = New Date(1900, 1, 1, CInt(arr1(0)), CInt(arr1(1)), 0)
        Dim dEndTime As Date = New Date(1900, 1, 1, CInt(arr2(0)), CInt(arr2(1)), 0)
 
        'If repeat booking is needed then declare variable to hold end date
        If McEndDate.Visible = True Then
            Dim dEndDate = McEndDate.SelectionRange.End
        End If

        'Set current date
        Dim CurrentDate As DateTime = DateTime.Now

        'Check that all data is selected, except optionals
        'Check that selected date is not earlier than current date
        If dStartDate < CurrentDate Or dEndTime < dStartDate Then
            MessageBox.Show("Error! Date selected is invalid", "Error!", MessageBoxButtons.OK, MessageBoxIcon.Error)
            Exit Sub
        End If

        'Check start & end time
        If cbStartTime.SelectedText = "" Or cbEndTime.SelectedText = "" Then
            MessageBox.Show("Error! Please select a valid Start & End time!", "Error!", MessageBoxButtons.OK, MessageBoxIcon.Error)
            Exit Sub
        End If

        'Search Database for rooms matching criteria
        'Open connection
        connection.Open()



        Dim SearchRooms As New SqlCommand("SELECT Location WHERE 

(And obviously this is where im stuck

any help would be greatley appreciated!

This is all just basic SQL syntax that you'll be able to pickup easily by reading this.

ah cheers :) i'm still pretty new with using SQL >_<

this is the basics of a select statement

Select from sometableName where SomeField1 = somevalue1 and SomeField2 = somevalue2
