Sql Query Doesn't Return Any Results On Datagrid

Jul 7, 2010

I'm using Visual Studio 2005, and I have a datagrid connected to a table from an Access database.

I added 4 textboxes so the user can type search filters to search within the table and a "search" button.

Then, I created a query using the "add query" tool on the datagrid. I wrote it like: select field1, field2, field3, field4, field5, field6 from table where field1=? and field2 like "%"+?+"%" and field3 like "%"+?+"%"
and field4 like "%"+?+"%"

Both field5 and field6 aren't search criterias, so I didn't add them to the query. Once the query was created, I replaced the parameters inside the procedure with my textbox1.text, textbox2.text, textbox3.text, textbox4.text and then cut and pasted the whole thing inside my SEARCH button click event, so the query is executed when the user clicks on the button.

Now the problem is: when I search using the first field it goes ok, but when I try to search by any of the other fields it returns zero results, even though I double-checked I had written the words correctly. I don't know why it does this. I already tried deleting the datagrid and creating it again.[code]...

Establish A Connection To MySQL Via VB & Display Simple Query Results On A Form?

Dec 12, 2010

I have a project in Visual Studio 2008 and there is a working data connection to a MySQL database. In other words, I can query the db directly from Visual Studio and it will display the results.

I've tried a couple of approaches that I found online for writing a connection string and accessing the db, but no luck yet.

All I'm trying to do is code a button to query the db and then reset the text property of a label/textbox to display the results based upon another label/textbox value.

The pseudo-code I am imagining is something like this:

Private Sub query_submit_button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles query_submit_button.Click
result_textbox.Text = SELECT field FROM table WHERE otherfield = key_textbox.Text
End Sub

I didn't see any related questions posted on SO - forgive me if I missed one that already exists and this is a dupe.

What is the correct way to accomplish this?

EDIT
Using MySQL 5.1

Formatting SQL Query Results?

Feb 3, 2009

If this is in the wrong section, I have a program that queries a database and puts the info in a specific format in a txt file. Now my problem comes w/ how to format the date.

Should I format the date in the SQL query OR is there a way to take the result from the query and format sometime before it is writen to the txt file? I'm not exactly sure how to do either. Would I need a subquery to get the desired date format?

[02/03] Exporting SQL Query Results To .txt?

Jan 9, 2009

I'm trying to execute a SQL query and pull the results into a text file. However, I'm getting an error in the bolded part. I think probably the biggest help would be an explaination of what the code in bold is actually doing. I pulled this from a book but don't think I completely understand. To me it seems like its saying that for each row in table 'extract'. Extract it, and write it?? But it doesn't seem to work that way. When it gets to that part, the error I get says that the row doesn't exist in the table

Private Sub btnExecute_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExecute.Click
Cursor.Current = Cursors.WaitCursor 'hourglass cursor

Asp.net - LINQ-to-SQL Query Returning No Results?

Mar 5, 2011

I have a query using LINQ-to-SQL. It queries an underlying database table Rooms. It uses Where conditions to narrow down the results, namely:

Gender.Current Occupancy < Max Occupancy Available Flag is Checked I know this should return results but it keeps returning an empty set.Code is below

UPDATE: I've verified that the issue is with the statement where sh.is_available = 1, which doesn't make sense since this is a bit field.

Asp.net - No Results From Oracle Query In VB ASPX?

Jul 10, 2009

Why would a VB/ASPX page not return results for a query which runs fine with other Oracle clients? (Same username) The following code should first output the query and then execute it outputting a single exclamation point per record. However, it outputs the query (as it should), but does not return any rows (nor error). If I copy the query to SQL Plus (or other editor) as the same user, the query returns results.

Why might my code not output any results?

Dim MyQuery As String = "...some query..."
Dim Factory As DbProviderFactory = DbProviderFactories.GetFactory("System.Data.OracleClient")
Dim myConn As DbConnection = Factory.CreateConnection
Dim myCommand As DbCommand = Factory.CreateCommand
Dim MyReader As DbDataReader
