Failed To Open Database Because Database Is Read-only?
Jun 18, 2011O/S WIndows 7
SQL Server : SQL Express 2008 R2
VB 2010 Express
SQL Server is located on the workstation so the code and the DB are on the same PC
Created a DB connection using the wizard. Tried this with Windows authentication and SQL authentication using sa
Created a Dataset and dragged the grid onto the form1.vb.
In SQL Sertver Management Studio I can update update tables using the same credentials as in the VB connection string
WHen I try to update a record in the VB Dataset it returns the error cannot update database because it is read-only
I have checked the files and folder attributes in SQL Data folder. Nothing is set to read only
I have checked SQL Server Database > Properties > Option > State > Databse Read only = false
I don't what I'm doing wrong here but I cannot get VB to update data via the dataset.
Inotice in SQL Server that the DBname now includes the full path "C:PROGRAM FILESMICROSOFT SQL SERVERMSSQL10_50.SQLEXPRESSMSSQLDATAPAYABLES.MDF" and not just the DB name. Is this becuase VB Express requires you to point to the physical DB file?
Failed To Update Database "path" Because The Database Is Read-only

Apr 4, 2012i am new to working with databases, I have done some of my own research and have been adding and regtrieving records without trouble. Now I need to retrieve a specific record based on a selection made by the user. I found that the way to do it is with the WHERE statement and from examples i have seen the code below should be how it is done:[code]The problem I am having is that when i try to run the sub i get the error:Syntax error (missing operator) in query expression 'Show Name = Strictly Hip Hop'.The show name is in the database because that is where the data is retrieved from.

How To Read Single Result From SQL Database
Jun 19, 2009I am trying to read a single result from an SQL table. I tested my query in MySQL Query Browser and it returns a result of USER_ID=4. My query:
SELECT USER_ID FROM aaalogin where NAME = 'administrator'
I believe my error is due to some "double quoting". I have a "txtUsername" textbox on my login form. I want to inject the typed entry from this textbox into my SQL QUERY. Notice the end of this line, I have tried tons of combinations, nothing works.
myCommand.CommandText = "SELECT USER_ID FROM aaalogin where NAME = " & " ' txtUsername.Text ' "
The result is ALWAYS "0" though, which is useless to me.
Full code below:
Imports MySql.Data.MySqlClient
Imports System.Data
Public Class frmLogin
Private Sub cmdCancel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdCancel.Click
