I have a locally installed MS SQL server 2000. I am trying to retrieve the contents of the table onto a datagrid. But when I use the user name and password, It gives the following errorSystem.Data.SqlClient.SqlException: Login failed for user 'aroop'. Reason: Not associated with a trusted SQL Server connection. string connectionString = "server=(local); uid=aroop; pwd=abcdef; database=mydb"; string commandString = "select * from mytable"; SqlDataAdapter dataAdapter = new SqlDataAdapter(commandString, connectionString);
DataSet dataSet = new DataSet(); dataAdapter.Fill(dataSet);
dgEmployees.DataSource = dataSet; dgEmployees.DataBind();Can someone please let me know what to do about this?
I am using MFC ODBC classes in my VC++ application for database accesss (on a SQL Server 2005 Database). After opening a Recordset I have to use the CRecordset::GetFieldValue( LPCTSTR lpszName, CDBVariant& varValue, short nFieldType = DEFAULT_FIELD_TYPE ) method of the CRecordset object to obtain field values. The above method works fine with ODBC drivers for Jet but when I use ODBC for SQL Server it throws the following exception.
State:S1002,Native:0,Origin:[Microsoft][ ODBC SQL Server Driver] Invalid Descriptor Index
I don't understand why the Microsoft SQL Server ODBC Driver is throwing this exception.

hai everybody!!!!! am working wirh visual 2005 and sql server()asp.net).....so i need the coding in VB for searching one record from a database table according to the id..and want to display it.....
Code Block SELECT tce.TimeCardID, tce.TimeCardExpenseID, tc.DateCreated, e.LoginID, e.FirstName + ' ' + e.LastName AS FullName, tce.ExpenseAmount, tce.ExpenseDescription, op.ProjectName, op.ProjectDescription, ec.ExpenseCode FROM OPS_TimeCards tc JOIN OPS_Employees e ON e.EmployeeID = tc.EmployeeID JOIN OPS_TimeCardExpenses tce ON tc.TimeCardID = tce.TimeCardID Join OPS_Projects op ON op.ProjectID = tce.ProjectID Join OPS_ExpenseCodes ec ON ec.ExpenseCodeID = tce.ExpenseCodeID WHERE e.LoginID = 'jross' ORDER BY tc.DateCreated DESC
this query returns me the correct data....but i need to tweak the query so it does not duplicate rows....My tce.TimeCardID is a PK in its table and so is TimeCardExpenseID...but the problem is U can have many TimeCardExpenseID's for one timecard so my results look like
TimeCardID TimeCardExpenseID 1 2 1 3 1 4
I want my query to return the "TimeCardID" but i just want that one ID to represent all the TimeCardExpenseID's...but i can not get it to work and have no clue....
hi I have used the following code (mostly created by MSDN) to retrive a binary field from SQL database. it works but I have extra space between characters. for example if I save a text file with "Hello world" text, after retriving I have it like "H e l l o w o r l d". what is the problem?????? I am really looking forward your answers private void retrive() { public void a() { SqlConnection connection = new SqlConnection("Some Connection string"); SqlCommand command = new SqlCommand("Select * from temp", connection); // Writes the BLOB to a file FileStream stream; // Streams the BLOB to the FileStream object. BinaryWriter writer; // Size of the BLOB buffer. int bufferSize = 50; // The BLOB byte[] buffer to be filled by GetBytes. byte[] outByte = new byte[bufferSize]; // The bytes returned from GetBytes. long retval; // The starting position in the BLOB output. long startIndex = 0; // Open the connection and read data into the DataReader. connection.Open(); SqlDataReader reader = command.ExecuteReader(CommandBehavior.SequentialAccess); while (reader.Read()) { // Create a file to hold the output. stream = new FileStream( "C:\file.txt", FileMode.OpenOrCreate, FileAccess.Write); writer = new BinaryWriter(stream); // Reset the starting byte for the new BLOB. startIndex = 0; // Read bytes into outByte[] and retain the number of bytes returned. retval = reader.GetBytes(0, startIndex, outByte, 0, bufferSize); // Continue while there are bytes beyond the size of the buffer. while (retval == bufferSize) { writer.Write(outByte); writer.Flush(); // Reposition start index to end of last buffer and fill buffer. startIndex += bufferSize; retval = reader.GetBytes(0, startIndex, outByte, 0, bufferSize); } // Write the remaining buffer. if (retval != 0) writer.Write(outByte, 0, (int)retval - 1); writer.Flush(); // Close the output file. writer.Close(); stream.Close(); } // Close the reader and the connection. reader.Close(); connection.Close(); } }
I am using FileUpload method in tools box and i want to store the uploaded image into database. but when debuging it will shows an error like: Operand type clash: sql_variant is incompatible with image this is the code for "upload" button.Protected Sub uploadbtn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles uploadbtn.Click If FileUpload1.HasFile Then TryFileUpload1.SaveAs("C: emp" & FileUpload1.FileName) Label1.Text = "File name: " & FileUpload1.PostedFile.FileName & "<br>" & "File Size: " & FileUpload1.PostedFile.ContentLength & "kb<br>" & "Content Type: " & FileUpload1.PostedFile.ContentTypeCatch ex As Exception Label1.Text = "ERROR: " & ex.Message.ToString End Try Else Label1.Text = "You have not specified a file" End If Try SqlDataSource1.Insert() Label2.Text = "picture is saved"Catch ex As Exception Label2.Text = ex.Message.ToString End Try End Sub
hello dear friends I am trying to save a binary file to database with the following code: public static void memorystreamToDb() { MemoryStream mst = new MemoryStream(); UnicodeEncoding u = new UnicodeEncoding(); string Textn = "Test"; byte[] b = u.GetBytes(Textn); mst.Write(b ,0,Textn.Length ); BinaryReader reader = new BinaryReader(mst); byte[] file = reader.ReadBytes((int)mst.Length); using (SqlConnection connection = new SqlConnection("Some Connection String")) { SqlCommand command = new SqlCommand("INSERT INTO temp (examplefile) Values(@File)", connection); command.Parameters.Add("@File", SqlDbType.Binary, file.Length).Value = file; connection.Open(); command.ExecuteNonQuery(); } reader.Close(); mst.Close(); } or with the other method from a real file (not memory stream) public static void Addfile(string path) { CommonMethods_class k = new CommonMethods_class(); byte[] file = GetFile(path); using (SqlConnection connection = new SqlConnection(k.Get_connection_string())) { SqlCommand command = new SqlCommand("INSERT INTO temp (examplefile) Values(@File)", connection); command.Parameters.Add("@File", SqlDbType.Binary, file.Length).Value = file; connection.Open(); command.ExecuteNonQuery(); } } and after running each of them seams that the file have been saved; but I can not retrive the files. I have tried some solutions from msdn but inside the created file is empty. the point that i really look for it is to just working with memory not in the disk before saving. and then retriving each field that I want. looking forward your points thank you in advance

I'm trying to figure this out I have a store procedure that return the userId if a user exists in my table, return 0 otherwise ------------------------------------------------------------------------ Create Procedure spUpdatePasswordByUserId @userName varchar(20), @password varchar(20) AS Begin Declare @userId int Select @userId = (Select userId from userInfo Where userName = @userName and password = @password) if (@userId > 0) return @userId else return 0 ------------------------------------------------------------------ I create a function called UpdatePasswordByUserId in my dataset with the above stored procedure that returns a scalar value. When I preview the data from the table adapter in my dataset, it spits out the right value. But when I call this UpdatepasswordByUserId from an asp.net page, it returns null/blank/0 passport.UserInfoTableAdapters oUserInfo = new UserInfoTableAdapters(); Response.Write("userId: " + oUserInfo.UpdatePasswordByUserId(txtUserName.text, txtPassword.text) ); Do you guys have any idea why?
I have a sql server 2008 backend with an Access 2007 frontend database. Each time I export a query I get the following error:
Code: Microsoft Access was unable to append all the data to the table.
The contents of fields in 0 record(s) were deleted, and 1 record(s) were lost due to key violations.
*If data was deleted, the data you pasted or imported doesn't match the field data types or the FieldSize property in the destination table. *If records were lost, either the records you pasted contain primary key values that already exist in the destination table, or they violate referential integrity rules for a relationship defined between tables. Do you want to proceed anyway?
I don't know what if anything is actually missing because of the amount of data is more thant 6000 records. It seems everything exported but I would have to comb through the data to be sure.
I use select @@identity to return @@identity from my store procedure,but I could not retrive it from my Visual basic code, like variable=oRS.fields.item(0).value, it always says item can not be found....

This is DataSet retriving code from IBUYSPY Events Module.
public DataSet GetEvents(int moduleId) {
// Create Instance of Connection and Command Object SqlConnection myConnection = new SqlConnection(ConfigurationSettings.AppSettings["connectionString"]); SqlDataAdapter myCommand = new SqlDataAdapter("GetEvents", myConnection);
// Mark the Command as a SPROC myCommand.SelectCommand.CommandType = CommandType.StoredProcedure;
// Add Parameters to SPROC SqlParameter parameterModuleId = new SqlParameter("@ModuleId", SqlDbType.Int, 4); parameterModuleId.Value = moduleId; myCommand.SelectCommand.Parameters.Add(parameterModuleId);
// Create and Fill the DataSet DataSet myDataSet = new DataSet(); myCommand.Fill(myDataSet);
// Return the DataSet return myDataSet; }
My Question is
1) Is this ideal way to retrive data? 2) Will it return connection back to pool?
