Which method would be fastest / most efficient?
A) Read all data (822 rows) including those I do not need then filter / output those I do
B) 3 Round trips to the db using params filled via the last query to select only the data I need

im just starting to work with some database stuff, and ive got data binding done but im a little stuck with filtering. Ive got a test project, which has
-- listbox (bound to column 2/firstname)
-- Combo box (Has items added, with the same names as the items in colunm 3. so it has 'RPG' and 'Puzzle')
Now what im trying to do is when the item in the combobox is changed say to 'RPG' only items in the db which have 'RPG' in the surname column are displayed in the listbox. Been Google'ing and reading but all i can find is examples relating to a dataview and i cant get them to work/adapt to my situation.

I'm trying to access the SQL DB I have designed within my project in Visual Basic 2010 (.NET code seems to work for me 99% of the time) at runtime so that a user can select a method by which to filter a DataGridView.I have a fantasy football draft application that fills the DGV from a Table Adapter. The database is named NFLPlayerDataBase.mdf, the dataset used to fill the DGV is TabNFLPlayers11BindingSource1, the table adapter is TabNFLPlayers11Table Adapter1. The DGV is dgvDraft. Idk if that helps at all.If the user wants to look at only RBs while making their draft choice, I want them to be able to select RB from a drop-down and have the DGV be filled with the query that selects only RBs from the table. I have the drop-down already set and am able to fill in the DGV when the form initializes. I just can't get it to fill with the query request for a specified position.The table I'm looking to use from the .mdf is tabNFLPlayers11 and the column header that will be searched through the filter is "Position." Options are QB/RB/WR/TE/K/DST and will be selected by the user from a drop-down.I cannot find a way to even open the connection whenever I change the value of the drop-down.

I have a database that I would like to filter characters from anywhere in the field. Example the letter A is typed into textbox1 and in the grid every field that contains an A is show. Like dash, lap, trap, apple. Currently with the query I'm using it will just go from the beginning of the field. I get "Index was outside the bounds of the array". The code is as followed:
Dim filter1() As String
filter1 = TextBox2.Text.Split(" ")
Sheet1BindingSource.Filter = "Stationary_location like '" & filter1(0) & "' Stationary_location like '" & filter1(1) & "'"

I want to filter data on the textchange event on listview so I use dataview to filter data. Issue in the below code is, I use dataview inside for each so that it checks only one condition that is last value only it takes, I want to check value in s1 with dataview and remaining value should bind with listview. E.g.: if I type an in textbox it should list all the item values starting with an value like anandha kumar, anna etc. Suppose I keep the value anandha kumar and anna in array s1. I should list all other values expect the array values like antony etc... in listview.
protected void TextBox1_TextChanged(object sender, EventArgs e) {
dvProducts = (DataView)Session["ListViewItems"];
string serachText = EscapeLikeValue(TextBox1.Text);
string lvValues = hdRetailCustomerGroup.Value;
string trim = lvValues.Replace(" ", "");

I have an arraylist that holds a subset of names found in my database. I need to write a query to get a count of the people in the arraylist for certain sections i.e. There is a field "City" in my database from the people in the arraylist of names I want to know how many of them live in Chicago, how many live in New York etc.
how I might set up an sql statement to handle this. I think somehow I have to pass the subset of names to sql somehow.
Here is a sample how I am writing my sql in my code
Public Shared Function GetCAData(ByVal employeeName As String) As DataTable
Dim strQuery As String = "SELECT EMPLID, EMPLNME, DISP_TYPE, BEGIN_DTE FROM Corr WHERE (EMPLNME = @name)"
[Code]....
I need a way to create a function using your sql statement to return a datatable object of names and the parameters would be city, and the List of names.
The above example isnt the sql I am looking for its just a skeleton of what the function would look like that I want to create.
So then you would use the function by iterating through all the cities passing in the same set of names each time in the fron end.

I have an idea, but i am not sure how to implement it with code.I have an application where a user can view current bookings for rooms.I have two datagridview controls, the first one shows the rooms and the second shows all my current bookings.What I want to be able to do or more the user, is click on a room and the current bookings for that room (datagridview1) to be shown in (datagridview2).What I think I need to do is apply a filter and a sort in a sub routine, then link my tables with a binding source.

I have a code which can get the MAX value of distinct "SYSID" field. Now, I plan to add a data filtering by time - Start and End time. I have tried but getting all sorts of error and can't get what I'm after for. So the program should do the data filtering (data >=starttime and data <=endtime) first before getting the max value of "SYSID"
Below is my
Private Sub Get_Max()
Dim ci As New CultureInfo(CultureInfo.InvariantCulture.LCID, True)
Dim dtfi As New DateTimeFormatInfo()
dtfi.ShortDatePattern = "MM/dd/yyyy"
dtfi.ShortTimePattern = "hh.mm.ss"

I have this database and I need to load it with a visual basic form in Visual Studio 2005.The database has 6 tables and they contain wrong data that I must filter when loading the database in the form.
A quick example:First table is Category, which has 3 fields (id, name, description). In one record I have 2a for id (a numeric only field) and in other record I have m1lk for name (a string only field).
When I click a button I load the database into a DataGridView control. How do I stop visual basic from loading into the DataGridView control those records that have invalid data (like in my example).
I have try with SQL queries using WHERE and LIKE, like in
SELECT IdCategoría, NombreCategoría, Descripción
FROM Categorías
WHERE (NombreCategoría LIKE '[!l]%') AND (IdCategoría LIKE '[!abcdefghijklmnñopqrstuvwxyz]')
but it's really difficult to filter things like Angel* and P3ter and Hood8, all at the same time..

I have a CombBox and a data grid view on a form, when the form loads, the data grid view is loaded with data from the database. I want to filter that data with a selection from the combobox (which is loaded with data from another database). The code i have is as follows:
ContactsBindingSource.Filter = "Company Like '%" & Me.cmbSelectCompany.Text & "%'"but when I select an option from the drop down list the DGV gets cleared down as if my selection has no equivilant data in teh DGV.
