Hi everyone,
I am trying to do a select sub-query, but for some reason it is not working out.
I have the following stored procedure:
CREATE MyProcedure
@newID int,
@oldID int
AS
INSERT INTO MyTable(ExperimentID, Threshold, Energy) VALUES(@newID, Select Threshold, Energy from OldTable where ExperimentID = @oldID)
This mixing of a given value with a subquery does not seem to work. However, there must be a mechanism to do this. Does anyone has some experience with something like this and can maybe help me.
Thanks a lot.
Cheers,
Pankaj
Without struggle, there is no progress

 i am using MSDE and i'm trying to create new database but the connection security option is always Integrated Security is that means that anybody can get access to my data and if ues how can i protect my data.

If Integrated Security is set to SSPI, MSDE uses Windows Authentication - it takes your system logon credentials as being the credentials to log on to the database with. If you don't set Integrated Security, you must provide a username and password.
In the Integrated Security mode, MSDE uses the local system's Windows password database if the connecting process is using a local account, or contacts the domain controller if using a domain account. In the Mixed Mode ('Use a specific user name and password'), the user names and passwords are stored in MSDE's msdb database. The MSDE install defaults to Windows Authentication mode - an attempt to connect without using Integrated Security fails.
Integrated Security is generally considered to be more secure than specifying a username and password in a connection string.
Even this isn't the whole story, because logins (how you connect to the server) are mapped to server roles on a per-server basis (which control things like being able to BULK INSERT, adding other users, shut down the server), and to users at a database level. Users can be granted permissions to create tables, select data, insert data, execute stored procedures, etc. SELECT, INSERT, UPDATE and DELETE permission is granted on a per-table basis; EXECUTE permission is on a per-procedure basis.
To simplify managing users, databases also have roles, which are the equivalent of Windows groups. Roles and users can be either be Granted permission, explicitly Denied permission, or neither. If a user or one or more of their roles has Grant permission, and neither the user nor any roles have Deny permission, permission is granted. This allows you to say 'Grant all members of the public role permission, except Bill'.
The system comes initially configured with BUILTIN\Administrators (the Administrators group on the local machine) and sa logins, which are both made members of the Server Administrators server role. They are both mapped to the 'dbo' user in the master and model databases; dbo is a member of the public and db_owner roles in these databases. By default public has no permissions granted or denied; db_owner has all permissions granted (this cannot be altered).
If you have the full SQL Server, I recommend using Enterprise Manager to edit configurations. Otherwise, you need to look at the sp_addlogin and sp_grantlogin system stored procedures, for starters.

i m a beginner in .net, especially in ado.net..i want to del a row from a table having one parent table and one child table...i m trying through delete method of datarow class but couldnt do...
one exception occurs wen i use delete method that the table has no row at given index...plz tell me wat to do??????
meroo rana

It means that you specified an index which is bigger than DataTable.Rows.Count. If you want to delete the last row in the collection you have to use the index of DataTable.Rows.Count - 1. Remember that the Count tells you how many rows you have, but the collection starts from 0 and not 1.
The other thing, when perfoming a certain operation on a table which is in a relationship with another table, you have to follow a little guidline:
1. When inserting, insert first to the parent table and then the child table.
2. When updating, update the parent table first and then the child table.
3. When deleting, delete from the child table first and then from the parent table.

Microsoft SQL server version 7.0
---------------------------------
I have to find out a way..where in the login id and passwords can be stored
in more secured way..
I browsed the netb and found out the following information..does this apply to sql server 7.0 ?
"
Passwords are stored in the sysxlogins table in encrypted form.SQL Server uses an undocumented function, pwdencrypt() to produce a hash of the user's password, which is stored in the sysxlogins table of the master database.
When a user attempts to authenticate to SQL Server several things happen to do this. Firstly SQL Server examines the password entry for this user in the database and extracts the "salt" - 84449305 - in the example. This is then appended to the password the user supplies when attempting to log in and a SHA hash is produced. This hash is compared with the hash in the database and if they match the user is authenticated - and of course if the compare fails then the login attempt fails.
The user's password is converted to it's UNICODE version if not already in this form.The salt is then appended to the end. This is then passed to the crypt functions in advapi32.dll to produce a hash using the secure hashing algorithm or SHA. The password is then converted to its upper case form, the salt tacked onto the end and another SHA hash is produced."
This methodos storing is adopted by SQL server..
in this method...hacking the passwords sounds so easy!
so..
Can someone suggest a better way for storing the passwords and the login information..
storing it in teh registry is also not safe .,I guess!
thank u..

Unless someone has found a way of generating passwords from their salted hash value, I don't understand what the problem is....

while i executed a sql string to insert a new record, one of the fileds of this record had a length of 500, this field in the ORCAL database had been design to have 1000 VARCHAR2(1000),i executed this command string in TOAD,it had no problem, but when i used ado execute method of command object, the function didn't return, and did't report any error, so ,what is the problem ?
the sql string is :

I don't think you can change the sequence in the DataView. DataView "binds" to the DataTable and DataTable forms the columns based on the SQL string or stored procedure. You should change the order in you SQL string or stored procedure.

The following is the way i want to implement this.
that is..to check iff
permissiosn()&2=0x2....permissions()&32=0x20 and so on...
CREATE PROCEDURE balli
@ioparm int output,
@oparm int output AS
BEGIN
SET NOCOUNT ON
IF PERMISSIONS() &@ioparm=0x@oparm
SELECT 1
ELSE
SELECT 0
END
The above sql proc gives syntax error..how do i change it??

A couple of problems: your parameters should not be specified as output, because you're passing the values into the stored procedure. The parameters are also badly named - indeed, I'm not sure you need two parameters, because you're just trying to see if a particular flag is set.
The syntax error is coming from 0x@oparm. The prefix 0x tells SQL Server that the following characters should be interpreted as a hexadecimal number literal. If you want to do that, specify hex when assigning a value to the parameter, don't include it in the query text. @ isn't a valid character in a hex literal, so SQL Server complains.
With that in mind, I would just SELECT PERMISSIONS() and perform the mask operation in client-side code. Testing each bit separately is a waste of network and server resources.
In Visual C++, you use the & operator to mask, then == to compare. == has a higher precedence than &, so you need to use brackets to ensure that the AND operation is done first. In VB, use And to mask and = to compare.

I have a field called validfrom and validto inside my Table I want a user to be able to enter two dates and then my page pulls back all the data where there dates fall inside the dates in the DB.
something like
SELECT * from table where form.date1 and form.date2 fall between "VALIDDFROM" and "VALIDTO"
So I have a validfrom date January and a validto date of december in the db in same record
but my user types in feb to march
as
feb to march falls inside the jan - dec period
that result is pulled to the broweser?
Working with MsAccess and ASP
Thanks

I am trying to write a query against a view to return a recordset to a webpage and can't get my where and and's to work right. Any suggestions would be greatly appreciated.
SELECT *
FROM sde.view_projects
WHERE Docu_Title AND Docu_Type AND Docu_Date AND Docu_Author LIKE '%VAR%'
What do you think? It does not want to take the AND, I am looking for contain's from any/all of these fields.
This is from and ASP Page talking to SQL 2000!
Thanks for your time!

As a general rule I like to stack my AND clauses so that they are additive: (Docu_Title LIKE someTitle) AND (Docu_Type LIKE someType) AND ... well, you get the idea. I'm no expert, but I really think you need to recast this query in a more explicit form. You're asking for an awful lot from a fairly simple inference engine. Each LIKE clause should stand alone, and be joined by AND clauses.

Not sure how to word this, or maybe my brain just isn't working today:
I need to add records to a table. I know how to do this if I SELECT a set of data prior to adding a new record, but I would like to do it without having to do a SELECT first.
Or, how do I open an empty recordset for a table? I am trying to avoid the delay of SELECT searching a large table only to come up empty.
Apologies if this doesn't make sense or is ridiculously simple (see line 1).

Ok, brain kicked into gear.
SELECT TOP 0 * FROM tablename
