Thanks Mika.
Yes we can use Instead of Triggers where we face problems in delete/ update statements. But I got the idea from your answer that using views doesnot impact any performance as I have to issue the select statement either in Stored Procedure or View.

You can't. SQL server need exclusive access to it when it is running as a database.

Hay ..
in SQL server 2005
I can make any select statement , but how can I get the last record :
like that
id invNo
1 a1
2 a2
3 a3
<br />
@newinv nvarchar(10) output<br />
AS<br />
SET NOCOUNT ON<br />
begin<br />
SELECT * FROM table ORDER BY invNo<br />
end<br />
<br />
I want to get the field invNo of the last record then by substring function i can add One ..
I hope my question is clear .

Great minds think alike...

"select top 1 InvNo from table order by id DESC" -- ASSUMES ID IS AN IDENTIY FIELD, OPR AT LEAST THAT THE LAST RECORD HAS THE HIGHEST id
|
|
|
|
|
try this:
Select Max(idno) for last record and Min(idno).

Dear All,
I am trying to put the code for generating an eXcel file using xp_cmdshell into a stored procedure for the purpose of calling it from code.
The code was given by a member of one of the forums sometime back.
USE northwind
EXEC master..xp_cmdshell 'bcp "select ''categoryname'',''description'' union all select categoryname,description from northwind.dbo.categories" queryout "d:\Shared\test1.xls" -c -S"172.16.121.203" -U"sa" -P""'
The above code works brilliantly.
I tried to put it into a stored procedure but getting various errors.The sp creation code is as below:
CREATE PROCEDURE [dbo].[SpWriteExcel]
AS
--create a variable @sql
--DECLARE @SQLStatement varchar(500)
DECLARE @SQLStatement1 varchar(500)
-- @SQLStatement = USE northwind
SELECT @SQLStatement1 = "EXEC master..xp_cmdshell 'bcp select ' 'categoryname' ' ,' 'description' ' union all select categoryname,description from northwind.dbo.categories queryout 'd:\Shared\test2.xls' -c -S\'172.16.121.203\' -U 'sa' -P' ''"
--Execute the SQL statement
--EXEC(@SQLStatement)
EXEC(@SQLStatement1)
GO
The error is with SELECT @SQLStatement1. So I tried to change it in various ways but did not get any success.
One of the ways I changed it to is as below:
SELECT @SQLStatement1 = " EXEC master..xp_cmdshell 'bcp "+"select categoryname,description union all select categoryname,description from northwind.dbo.categories"+" queryout "+ "d:\Shared\test3.xls"+" -c "+"-S"+"172.16.121.203"+"-U"+"sa"+" -P"+""+"'"
Could you pls write a proc for me which contains the above command and which takes the database name, table name and the excel file path as parameters.
Thanks for your help.

Yes, I could, but I won't. The best solution is to print the sql rather tahn exec it, then you can see whats wrong. Its all part of the learning process, called debugging, and as a developer its something you should be able to do - after all, its what you are being paid for.

Hi,
iam using MySql db,
my stored procedure is like this..
DELIMITER $$
DROP PROCEDURE IF EXISTS `test`.`IS_CITY_EXISTS` $$
CREATE PROCEDURE `IS_CITY_EXISTS`(
IN CITYNAME VARCHAR(45),
OUT AVAILABLE BOOLEAN
)
BEGIN
IF EXISTS(SELECT * FROM city_details WHERE city_name=CITYNAME) THEN
SELECT 1 INTO AVAILABLE;
ELSE
SELECT 0 INTO AVAILABLE;
END IF;
END $$
DELIMITER ;
when iam executing this procedure works fine..
CALL IS_CITY_EXISTS('kak',@Available);
but while exceuting SELECT @AVAILABLE;--IT'S giving result null.
is there any error in procedure..
how can i call this procedure in (c#)..

I've never used MySQL but two observations still:
- you set delimiter to $$. However you use semicolon after the statements.
- is 0 equal to false in mysql or does it understand false keyword. If so, 0 may be interpreted to null since it's not false.
But then again, just guessing.
The need to optimize rises from a bad design.

Most likely the file you're trying to restore does not exist or the directory is wrong. Remember that when you issue a restore command, the file must be defined in a way how SQL Server service sees it.
