i need to write some lines to a txt when running loops in a stored procedure, is there any syntax facilitating this kind of function? or I have to use some other ways? if you have done that before, please help me, thanks..........

Look in BOL for xp_cmdshell.
Someone's gotta be the last to know, but why is it always me?

It's going to slow down your loop terribly if you keep writing to a file. You'd do better to store the logs in a table and write it to a file in one shot in the end. For that use xp_cmdshell as suggested in the post above or use a CLR procedure if you're using SQL Server 2005.

They Guys are Correct, i think its not a Good idea to write to a file directly from your Procedure. You can just create an SQL table and dump the logs there ,and later if you want you can transform that table into a txtfile.About using xp_cmdshell, you have to consider the security issues. if they are not a DBA in your Company i think your DBA will advise you not to use it.
Hope this Helps

hi Mika,
so I have to first create a table for this txt.file, and then I should use bcp command to generate a formatfile, right?
there is only one line like this example bcp command:
bcp AdventureWorks.HumanResources.Department format nul -c -f Department-c.fmt -T
how can I define that my first field in data file is 8 characters?
can you be more detailed, thanks very much..

Yes, the table must exist. Try something like this:
CREATE TABLE BulkTest (
Column1 bigint,
Column2 bigint)
Then create the format file using notepad and save it:
<?xml version="1.0"?>
<BCPFORMAT xmlns="http://schemas.microsoft.com/sqlserver/2004/bulkload/format" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<RECORD>
<FIELD ID="1" xsi:type="NativeFixed" LENGTH="7"/>
<FIELD ID="2" xsi:type="NativeFixed" LENGTH="1"/>
</RECORD>
<ROW>
<COLUMN SOURCE="1" NAME="Column1" xsi:type="SQLBIGINT"/>
<COLUMN SOURCE="2" NAME="Column2" xsi:type="SQLBIGINT"/>
</ROW>
</BCPFORMAT>
And then bulk insert the data:
BULK INSERT BulkTest FROM 'f:\orders\lineitem.tbl' WITH (FORMATFILE='f:\orders\BulkInsertFormat.txt')

hi all,
i write the following code for extract the data from a database, data also retrieved but there is a problem ...code is here
OracleConnection dataConnection = new OracleConnection();
ArrayList objList = new ArrayList();
try
{
dataConnection.ConnectionString = "Data Source=orc;Persist Security Info=True;User ID=scott;Password=tiger;Unicode=True";
dataConnection.Open();
OracleCommand datacommand = new OracleCommand("SELECT * FROM DEPT", dataConnection);
OracleDataReader datareader = datacommand.ExecuteReader();
Dept d = new Dept();
while (datareader.Read())
{
d.DNAME = datareader["DNAME"].ToString();
d.DEPTNO = datareader["DEPTNO"].ToString();
d.LOC = datareader["LOC"].ToString();
objList.Add(d);
}
datareader.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
dataConnection.Close();
}
try
{
cmbDname.DataSource = objList;
cmbDname.DisplayMember = "DNAME";
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
but i amazed ......all filled data of combobox is same i.e DNAME
like : OPERATIONS (which is last row of DEPT table)
because
objList store only last data (OPERATIONS)........
but when i replace
objList.Add(d); with
objList.Add(d.DNAME); then objList store different DNAME..........but this time objList has only one colum <dname>....
my problem is that how can i store whole row in objList

If you're trying to get your homework done by somebody else, nobody here will help you. The question you've asked is so trivial that google will throw up a million results for it. If you'd gone to school you would know most of the required fields by now.
Make an attempt yourself, explain what you've done, and then ask here if you still face any hurdles. We'll be more than willing to help if you've a genuine problem in your hands.

Hi,
I have an sql query that retrieves data for some ID where this ID has more than one data related to it.
Example:
ID Symbol
01 A
01 B
01 C
of course the primary key is (ID, Symbol).
when you select the ID and Symbol, it retieves the previous three rows.
I need to retrieve these data in one row by concatinating the Symbol to itself; i.e: I need the result to be just like the following:
ID Symbol
01 A and B and C
Is this possible???
Kind Regards
OBarahmeh

You could do this using a cursor[^] to loop through the rows and build up the string.
I wouldn't advise it for large resultsets as you could end up with performance issues.

Yes, it is possible 
CREATE TABLE #T (ID varchar(2), Symbol varchar(1));
INSERT INTO #T(ID, Symbol) SELECT '01', 'A'
INSERT INTO #T(ID, Symbol) SELECT '01', 'B'
INSERT INTO #T(ID, Symbol) SELECT '01', 'C'
INSERT INTO #T(ID, Symbol) SELECT '02', 'B'
INSERT INTO #T(ID, Symbol) SELECT '02', 'D'
--
SELECT
ID,
STUFF(
<code>(SELECT ' and ' + Symbol FROM #T WHERE ID = t.ID FOR XML PATH(''))</code>
, 1
, 5
, ''
) AS Symbols
FROM #T AS t
GROUP BY ID
--
DROP TABLE #T

I'm always amazed at the lack of functions in SQL Server.
There should be a JOIN CONCAT aggregate function.
There should also be TRIM (not just LTRIM and RTRIM), and PADding functions.
Ah, well, an opportunity to write my first CLR aggregate function! 
Ha! The example for creating a CLR aggregate is Concatenate! 
Whoo hoo! Copied the example and tweaked it a little.
SELECT ID
,Symbol=STUFF(dbo.Concatenate(' and '+Symbol),1,5,'')
FROM Symbol
GROUP BY ID
ORDER BY ID
,Symbol

Who is?

SELECT SymbolA.Id
,Symbol=SymbolA.Symbol + ' and ' + SymbolB.Symbol + ' and ' + SymbolC.Symbol
FROM Symbol SymbolA
INNER JOIN Symbol SymbolB
ON SymbolA.ID=SymbolB.ID
AND SymbolB.Symbol='B'
INNER JOIN Symbol SymbolC
ON SymbolA.ID=SymbolC.ID
AND SymbolC.Symbol='C'
WHERE SymbolA.Symbol='A'

Well... Let's just hope he is not using the whole alphabet for the Symbol field

I have a main report which has 2 parameters (int and bit).The report is working fine.
I have another report which is related to the main report and which has the same parameters (int and bit).
I am using the second report as subreport to the main report.
Done with the settings like passing the parameters and giving the name of subreport by right clicking the gray subreport box and selecting the properties.
Yet when I preview the main report I am not able to see the subreport.
what else settings i need to do?
Thanks in advance.
