Is there a utility or simple way to determine the size (number of bytes) of records in a table?
I'm trying to determine what I would save in disk space if certain records were removed/archived out of a SQL Server 2000 DB.
I understand that record size depends on contents (VARCHAR(30) vs CHAR(30)).
Thanks.

How about running:
exec sp_spaceused 'MyTableName' That gives you the number of rows, and the amount of space taken-up by the data and indexes.

That's exactly what I needed, Andy. Thank you.

There is a code which displays results of SQL-query in dataGridView:
dataGridView1.DataSource = bindingSource1;<br />
dataAdapter = new OleDbDataAdapter("SQL-query", connectionString);<br />
OleDbCommandBuilder commandBuilder = new OleDbCommandBuilder(dataAdapter);<br />
DataTable table = new DataTable();<br />
dataAdapter.Fill(table);<br />
bindingSource1.DataSource = table;
Whether probably in a similar way to display results of SQL in the table in reportViewe?
Thanks.

If you are using c# dot net catch a "SqlException" . In SQL procedure you can use RaisError function.

Dear Sylvester,
I want to know how i can achieve this in GUI i.e which property of the column can i use. is it by default value or binding and while doing this i can simply specify the value alone know, otherwise should i prefix the value with any special characters.

M. J. Jaya Chitra

when you create a column you can see a detailed section in the bottom. There you can set the default value.

I have the following Stored procedure. There is column named
"tcktreceived" in my database and I want to pass all the rows one by
one to the parameter @starttime. I don't know how to do it.
CREATE PROCEDURE [twcsan].[usp_DateDiff]
-- Add the parameters for the stored procedure here
@starttime DateTime
AS
BEGIN
DECLARE @Diff Varchar(15)
DECLARE @Day INT
DECLARE @Hour INT
DECLARE @Minute INT
DECLARE @Start_Date DateTime
DECLARE @End_Date DateTime
DECLARE @itemReceived DateTime
DECLARE @ID INT
DECLARE @message VARCHAR(50)
DECLARE @table TABLE
(
ItemReceived DateTime,
ID INT,
message text,
Differnce VARCHAR(20)
)
SET NOCOUNT ON;
SET @Start_Date = @starttime
SET @End_Date = GETDATE()
SET @Day = DATEDIFF( day, @Start_Date, @End_Date)
SET @Hour = DATEDIFF(hour , @Start_Date, @End_Date)
SET @Minute = DATEDIFF(minute , @Start_Date, @End_Date)
SET @Minute = @Minute-(@HOUR* 60)
SET @Hour = @Hour-(24* @Day)
SET @Diff = CONVERT(Varchar, @Day) +'d ' + CONVERT(Varchar , @Hour) +
'h ' + CONVERT(Varchar , @Minute) +'m'
INSERT INTO @table(ItemReceived, ID, message, Differnce)
select tck.tcktreceived, tck.ticketid,tckmsg.tcktmessage,@Diff
from tbtickets tck inner join tbticketsmessages tckmsg
on tck.ticketid = tckmsg.ticketid
select * from @table
END

Use CURSORs for that. However, that is generally very bad practice and should only be done when all other avenues have been exhausted.
SQL Server, and any relational database, works best on sets of data rather than individual items of data. If you can do what you want in one SELECT statement the operation will be much faster and you will use less resources on the SQL Server because you are taking advantage of its capabilities.
It might be best to tell us what the big picture is. Then we might be able to guide you to a set based solution.

Hi,
Here is my Specs. I created Stored Procedure Which I posted befor.for meeting the requriements
I will be really grateful if you could solve my problem.
I have a table which has a field "tcktReceived" of type datetime. I
have a grid view which has two columns.
In first column i have to show the data from field "tcktReceived" and
in second column I have to show
difference between Currenttime and date from tcktReceived.
e'g
ItemRecieved Difference
6/13/2007 12:38am 1d 21h 45m
6/13/2007 3:54pm 1d 06h 10m
6/15/2007 12:26pm 34m
So the second coulmn displays the difference of current time minus
ItemRecieved. the format shouild be <mintues>m,
or<hours>h, <mintues>m, or <days>d.
How can I do that.
Thanks in advance
seema

Create a function to calcualte the difference and format it as you need it.
Something like this:
CREATE FUNCTION dbo.TimeDifference(@startTime DATETIME, @endTime DATETIME)
RETURNS VARCHAR(20)
AS
BEGIN
DECLARE @Diff int;
DECLARE @Day int;
DECLARE @Hour int;
DECLARE @Minute int;
SELECT @Diff = DATEDIFF(minute, @startTime, @endTime);
SELECT @Day = @Diff / 3600;
SELECT @Hour = (@Diff - (@Day*3600)) / 60;
SELECT @Minute = @Diff % 60
RETURN CAST( @Day AS VARCHAR(5)) + 'd ' +
CAST( @Hour AS VARCHAR(5)) + 'h ' +
CAST( @Minute AS VARCHAR(5)) + 'm';
END
GO
CREATE PROCEDURE dbo.MyProcedure
AS
BEGIN
SELECT
tck.tcktreceived,
tck.ticketid,
tckmsg.tcktmessage,
dbo.TimeDifference(tct.tckreceived, GETDATE())
FROM tbtickets AS tck
INNER JOIN tbticketsmessages AS tckmsg ON tck.ticketid = tckmsg.ticketid
END
GO
