How Do I Retrive SQL Count Value Programmatically?
Jan 10, 2007
Hi Guys,
I have this SqlDataSource, that counts some records and sets it in
"NotStartedBugs".
How do I retrive "NotStartedBugs" programmatically?
<asp:SqlDataSource ID="SqlDataSource3" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT (SELECT COUNT(*) AS Expr1 FROM tickets WHERE
(TicketType = 'Bug') AND (TicketStatus = 'Not Started')) AS
NotStartedBugs"></asp:SqlDataSource>

Hi there,
I'm trying to keep track of the ETL process inserting/updating a row in one table for each package that finish in my ETL process when executing. So far, I created a Script task that increments by one a variable (counter) and then open a connection to my database an insert/update my table. What I want to see is Step 1/30, Step 2/30 and so on. Right know I can display Step 1, Step 2 but how can I get the overall number of tasks within a package?
Thanks in advance for any help you can give me.
Sincerely,
Ricardo

I've found example code of accessing an SQLDataSource and even have it working in my own code - an example would be Dim datastuff As DataView = CType(srcSoftwareSelected.Select(DataSourceSelectArguments.Empty), DataView) Dim row As DataRow = datastuff.Table.Rows(0) Dim installtype As Integer = row("InstallMethod") Dim install As String = row("Install").ToString Dim notes As String = row("Notes").ToString The above only works on a single row, of course. If I needed more, I know I can loop it.The query in srcSoftwareSelected is something like "SELECT InstallMethod, Install, Notes FROM Software"My problem lies in trying to access the data in a simliar way when I'm using a SELECT COUNT query. Dim datastuff As DataView = CType(srcSoftwareUsage.Select(DataSourceSelectArguments.Empty), DataView) Dim row As DataRow = datastuff.Table.Rows(0) Dim count As Integer = row("rowcnt") The query here is "SELECT COUNT(*) as rowcnt FROM Software"The variable count is 1 every time I query this, no matter what the actual count is. I know I've got to be accessing the incorrect data member in the 2nd query because a gridview tied to srcSoftwareUsage (the SQLDataSource) always displays the correct value. Where am I going wrong here?

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?

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

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();
}

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
