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();
}

View 2 Replies View Related,I am creating a database where each record is required to have a twin record in the database.These is a type a value and a type b value and both must be present for the record to be valid.
Customer_ID, Order_Type, Product_Code
54, a, 00345
54, b, 00356
Is this something that would have to be done programmatically, or is it possible to create a constraint of some sort to ensure this?

SELECT
tce.TimeCardID,
tce.TimeCardExpenseID,
tc.DateCreated,
e.LoginID,
e.FirstName + ' ' + e.LastName AS FullName,
tce.ExpenseAmount,
tce.ExpenseDescription,

Join OPS_Projects op

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....
so if i do Select * From TimeCardID = '1'
it should return
TimeCardExpenseID
2
3
4
Any help on how to get this done....
