Re: Error message in Stored procedure

For debuging purposes, you can add after each (SELECT, INSERT, UPDATE, DELETE, EXECUTE ...) command something like this:

IF @@ERROR <> 0 
  PRINT 'Insert into MyTable failed'

Raiserror('Message', 16, 1)

The above message will show up like an error thrown by the server. It'll get caught by try/catch blocks.

Try creating a new Maintenance Plan and use SQL server agent to schedule it to run automatically.

The easiest way is to open your management studio -> expand Management -> right click on Maintenance Plan -> choose "Maintenace Plan Wizard". Follow the instructions there.

You can put the code below inside a stored procedure and then create and schedule a job to run whenever you want.

DECLARE @cmd NVARCHAR(100);
SET @cmd = N'C:\BackUp_MyDatabase_'+REPLACE( CONVERT(NVARCHAR,GETDATE(), 121) ,':','.')  +'.bak'
BACKUP DATABASE [MyDatabase] TO DISK =  @cmd
GO

Try a varbinary(MAX)/BLOB field but first make sure your caps lock is off.

delete from student where rollno='12';
this is generally how we delete....and in generalized format
delete from student where rollno=@rollno;
but the above line is giving me error stating tht @rollno should be declared as a variable.
i am unable to solve it.....

First,

CREATE PROCEDURE spx_Student_Delete (@rollno INT)
AS 
delete from student where rollno=@rollno;
GO

Then use it like this

EXECUTE spx_Student_Delete 12

and it should work

Hi,

I am asking it again sorry if someone said it right and a got it wrong Sigh | :sigh:

I wrote a application in C# that connects to a sqlserver database.
The login to the application is wrote not in C# but SQL store procedures. I press a buttom that triggers a SP that manages the login.

Ok, but if someone copy and attach my database to other computer he can see everything in there! Because i enter my sqlserver by windows validation and i have no password in sqlserver.

my connection strings have both no password and user.
I want attach to be enabled only if you have user and password.

DO i have to create another login in my sqlserver and create with that new user a database? how i do that? i don ´t know how to create new user in sqlserver rather then the "master"

i spinning here Dead | X|

Hi
I already answered your first post on this, I'm sorry if you don't understand but here it isagain:

The best option in my opinion is to use windows groups to limit user access. It still uses windows authentication so no password verification etc, and you can then grant explicit permissions to the group. You can deny permissions as well as grant them, so deny select, insert, update, delete on your tables and grant exec on the stored procs.

Its a standard way of doing it and easy to maintain by scripts.

From this I must assume you are alreay using windows authentication, so you need to set the table permissions as I said. This will prevent someone attaching to you database and seeing the tables. I'm not sure how to explain thsi any clearer, but try google for granting permissions in sql server, it may help your understanding.

I am using SQL server.

e.g.

<br />
Create procedure sp_Fetchrecords<br />
@tbname sysname=NULL<br />
AS<br />
Select * from @tbname<br />
go<br />

check the store procedures folder if it is already there!
use alter procedure to change it.

i usualy set the database on which i write on sql server up-left corner combobox. i don´t not use code but you can do that, do you need to code that?

create procedures like this (with inner join)
--------------sp-----------

create procedure vendas_criadas

@data_ini as smalldatetime,
@data_fim as smalldatetime

as

begin

select ve.id_venda as 'ID Venda',al.nome as 'Album',cl.primeiro_nome+' '+cl.ultimo_nome as 'Cliente',ut1.primeiro_nome+' '+ut1.ultimo_nome as 'Criador',ve.id_utilizador_criador_data as 'Data Criação'
from dbo.vendas as ve
inner join dbo.albuns as al on ve.id_album = al.id_album
inner join dbo.clientes as cl on ve.id_cliente = cl.id_cliente
inner join dbo.SPY_utilizadores as ut1 on ve.id_utilizador_criador = ut1.id_utilizador
where ve.data_registo between @data_ini and @data_fim

end

go

-------------execute-------------------

exec vendas_criadas
@data_ini = '1/1/2007',
@data_fim = '1/1/2008'

SET NOCOUNT ON
IF @tbname IS NOT NULL 
BEGIN
	DECLARE @cmd NVARCHAR(4000)
	SET @cmd = 'Select * from '+@tbname
