How do I add a wildcard parameter to my query. Im using a mysql database. The following doesn't work:
Dim occCmd As New MySqlCommand("SELECT occupationid,descr FROM occupations WHERE lcase(descr) like '?descr%';", con)
occCmd.Parameters.AddWithValue("?descr", prefixText)
I have a form which takes input from the user in a TextBox to display ("contains") record/data on a grid. However, I am unable to achieve the input data thing. I have been trying to solve this for a while now. Dtatbase is MS Access.

This query fails on a dataset when I add the rating wildcard. The other two are fine but it does not like the %. This works fine if I run the SQL directly on SQL server.

SELECT Rating, InvDescrption, FullJobNumber, Product
FROM vJobLines
WHERE Product Like ? AND InvDescrption Like ? AND Rating Like The product and InvDescription fields are NvarChar where the Rating is Int32.
Im working on a project that includes a TableAdapter for filling data. I usually use parameters for queries I create, but what would be the best way to create a query that may have a wildcard without creating a bunch of queries?

I am connecting to an Access database and using a parameter query with the LIKE operator to return all rows that match query. The string to search for is taken from a Textbox
sql =
"Select * FROM Allview WHERE Info Like" &
"*" &
CStr(TextBox1.Text) &
"*"
The query does not return any data in vb, but when run from access with same string, there is data returned.The connection to the database is done correctly, as I am able to return data with various other queries.

I am trying to run a query an Access db from VB. The general query which I want to run is
SELECT * FROM Patient WHERE Patient.PatientID = ?
or SELECT * FROM Patient WHERE Patient.PatientLname = ?
I tried using an input box which captured the user input and pass that variable to the query, but that failed.

What I want to do is to replace lets say ##test## with Something(test)..I know that I can find ##test## by: (Though don't know whether there's a smarter way)
System.Text.RegularExpressions.Regex.Replace(str, "##Test.*##", "Output")
So basically the problem is to get what the wildcard (.*) is, since thats really what I need to know..

I am trying to load a combo box based on a selection of data from another combo box. I am not sure how I would pass the value to the object. My thought is I am loading all the table data onto my object and then I would run the query on the object. However I am at loss as to how I would go about doing that.

I am now able to add a row to Table1 in my database and and to populate some text boxes with that data. Now...one of those text boxes has a piece of data I wish to use as a variable/parameter in a SQL query to then populate several other text boxes. The piece of data in question is the Primary Key in a Table2. I have tried several methods I've discovered online...but nothing is working so far. So far I'm leaning towards the CommandBuilder but am unable to make it work.

I'm using a datagridview to display data and make updates to my access database. I was able to display data from my database to the datagridview but it is not filtered. The datagridview displays all the records on my database. I tried using query builder to execute sql select statements that will filter the data and this is where I'm stuck. Im using a variable as a parameter to the sql statement and I dont know what syntax to use in Query Builder. I tried to use @varname, '" & varname & "', and
View 1 Replieshow to pass a parameter to a predefined parameter in a dataset. I've found everywhere a solution if you build the sqldata adapter and the dataset in the code. Then you can pass the parameter like: da.SelectCommand.Parameters.Add("@param1", SqlDbType.Char).Value = param1_variable (as example)
But if you have builded a dataset (with table adapters), and then in the form app you want just to pass the param1 to a DataGridView1 (as example) which is using the table adapter, I did not find how to do this.

I have this code to retrieve a record to fill out a tooltip when the user's mouse enters a cell of a datagridview.
Dim dacmt As OleDb.OleDbDataAdapter
Dim con As OleDbConnection
Dim sql As String

This takes way too long for the tooltip to display. So, I created a query in the Access database that takes a parameter of the first field for the record you want.
How do I connect to just the query and send the parameter to it?
I am thinking this might be a quicker way to get the data for the tooltip. But then again, maybe not.
