I watched a video from Beth Messi about creating a search function using query builder.
For instance, if I want to filter FirstName, I will do " LIKE @FirstName + '%' " - the FirstName's datatype is varchar My question is, what should I write for the "int" datatype?
i connect the Datagridview by using command connection not coding. now i have "table3tableadabter", "table3bindingsource" and "database3dataset" below the form ? the search string " "Select * from tabel3 Where test2 like '" & Me.TextBox1.Text & "%';"" how i can do serch and the result will be shown in datagridview.

I'm using a 3rd party chart COM object (National Instruments CW graph) to plot data versus elapsed time.The x value needs to be a VB6 equivalent Date type which is a .NET DateTime datatype.What I need is a way to convert a TimeSpan datatype to a DateTime datatype.

Dim plotTime as System.DateTime 'date
Dim elapsedTime as System.TimeSpan[code].....
I have a database in mysql. The column in table is of datatype time(0)
Similarly I have a control datetimepicker in vb.net I have assigned format property as custom to the control and the CustomFormat property as HH:mm:ss tt so that it can just provide the time. I dont want the date to be in it.
Issue comes when I try to retrieve the value from database I get an error as Converion of type 'Timespan' to type 'Date' is not valid

I've got a searh form with about 8 different boxes where a user can enter data to search from. To save writing many different search commands I want to be able to write one and if the field is empty then search all records for example
SELECT * FROM MyTable WHERE CarType = CarType.Text And Color = Color.Text If a user enters a Color then search it otherwise don't narrow down the results so like this SELECT * FROM MyTable WHERE CarType = ""
How can I do this? would it be like the % sine if Color.Text is = String.Empty??
I am working on a produce inventory database in my VB Express program.I have a form on the bottom and a spreadsheet at the top. I want to enter all the data in the form and have that data automatically transferred as a group to the spreadshet in the upper part of the page when I press a button.I know that there's an insert function.I set it up correctly. The problem is that I have to convert the textbox, which contain string data, to the datatype used in the database spreadsheet.HOw do I use CAST or do this?Here's the function I am using:
Me.TableAdapterManager.InventoryTableAdapter.Insert(IDTextBox.Text, fruitName, unitprice, unitsize, unitIn, unitTransit, unitOut)
Evernything is a string cause the data is coming from a textbox, I need to convert it to the datatypes used in the database.Also how do I use the CAST and Convert functions

[code]Myself and a coworker have stared at this quite a lot and we can't figure out why it's not working. The problem is in the value for @ID (since it still works when I leave the other one parameterized). The funny thing is, Just a few lines of code above it I have a different query that sets a parameterized value for the same ID, using the the same choices list that the For Each loop is getting the match variable from.Choices is a list of longs, and when I use choices(0) to parameterize ID in a query, it works. But now down here in this loop I have the new match long, and it doesn't want to make it work for me.
View 1 RepliesI have a SQL 2008 Express database, which have following tables: [code] Now I need SQL query to search for word (i.e. Beyonce Halo Music Video) against these tables.
-For Title exact phrase will get 0.5 points
-For Description exact phrase will get 0.4 points
-For tags exact phrase will get 0.3 points
-For title all words will get 0.2 points
-For description all words will get 0.2 points
-For title one or more words will get 0.1 points
-For description one or more words will get 0.1 points
And I will show these videos on basis of points. What will be the SQL Query for this? A LINQ query will be more better.
Is it possible to Query or search or anything for a DBX file. We are looking to be able to pull out the Sender, Subject, Date of Arrival, Yes/No Attachment, and the body if possible of the message. I've found a bunch of programs online so it seems possible, but how do you do it? I'm currently using VB 2005 but could work this out in C# if VB isn't a good option.

Trying to figure out the right way to query a MySql database and find a user defined variable from a Textbox.Text property. I'm not sure what to put for the where clause in order to search every cell of every row for a match. I have looked at coalesce and contains, but neither are really making sense to me and I'm not sure if they are my best option. I'm thinking that the query string will look something like this:

I tried out the video tutorial from Beth Messi about how to create a search. The tutorial teaches us how to do it through query builder in which we just have to type LIKE@fieldname = '%' for each field we wish to appear on a toolstrip. A toolstrip menu will automatically be generated and placed underneath the form bar for us after we click ok.
Now, I would like to know how can I do this with code? I can use a code which will move the auto generated toolstrip into the tabcontrol but when I have more than 1 tabcontrol, that's when I start having problems - the toolstrips are starting to cover up the tabcontrol. I know I can move the datagridview lower but that is going to leave a big space above it.
I have 3 textboxes and need to search differently for each of the textboxes.

I have a VB.NET search routine, part of which is provided, below, that checks all Text cells in a DataGridView for a given string (inclusive), using a basic set of nested loops to perform the search:

' Skip the new row

is there a way to replicate this behavior using LINQ? Basically I would like the query to select (or return) the first DataGridViewCell whose text contains the search string. I've done some tinkering with sub-queries and the like, but I'm still having trouble wrapping my brain around the concepts (too many years of writing T-SQL, I guess).

I am trying to do a SQL query that checks for the presence or absence of a character's occurance in a field / column as a condition to retrieve the row. In this case I only need to test for existance of the specified character and in a similar query to test for the non existence. Not where it is or how many, just is it there or is it notI am using VB express.net 2008 and it uses, I think, MS SQL Server 2008.Using VB's instr() I can tell straight away if a string does or doesn't contain a character, but I would like to know this before I retrieve the row.
using the
WHERE .... and [mytable.myfield] LIKE 'Q'
or
WHERE .... and [mytable.myfield] NOT LIKE 'Q'
produces a result, but not a correct result. It does something but I can not say that it is working even part way.CHARINDEX gets an undefined function error MATCHES also gets an undefined function error?CONTAINS looks like it should work but I am still getting sytax errors with it, so I don't know how to use that predicate yet.
