How Can I Create A DTS Package To Update A Table With Data From A Notepad File ?
 

We are creating a process which will create a notepad file with a set of Unique key which we use to update the database. Am trying to create a DTS package to accomplish this...but it seems to be a trivial task. I can use Transform data task to lookup the text file but i need to write an update query which will update some fields of existing records.
Am not sure how can i map fields of Text file to the Database table field.
 
If any1 can help then it will be great

Archive Data Instead Of Deleting It To Prevent 4GB Data Limit
We are running SQL Server 2005 express on Windows 2003. The database server gets significant amounts of data.

 

Because of the 4GB data limit we have a daily cron task which goes through and deletes data older then 90 days.

 

We would like a way to archive this data instead of deleting it. Is there any way to take data and compress it and store it in a different way, so that if needed, customers can query directly out from the compressed data? Cleary querying from compressed would be slower but that is ok.

 

Any other solutions that would allow us to archive data instead of deleting it? Thanks.

Prevent Data Being Inserted Twice
I have a table with 3 columns: ID, Status, DateTime.

I created a stored procedure to insert a staus value for each ID. This will run every hour. The DateTime stores the time, date when the Status was inserted.

If the procedure was to be run a second time in hour window I do not want any Status to be inserted.

Note: that I cannot rely on the procedure being run at exactly the right time - if it was scheduled to run on the hour (i.e at 1:00, 2:00, 3 :00 etc) but didn't run until 1:20 it sould still be able to run at 2:00.

Does anyone know if there is anyway I can gaurd against this?

How Can I Prevent From Inserting Duplicate Data?
 
I have a table storing only 2 FKs, let's say PID, MID
Is there any way that I can check distinct data before row is added to this table?
For example, current data is
PID MID------------100 2001100 2005101 3002102 1009102 7523102 2449
If my query is about to insert PID 100, MID 2001, since it's existing data, i don't want to add it. Can I use trigger to solve this issue?
 
Thanks.

How To Prevent DBA From Getting Confidential Data Stored In SQL Server?
Suppose I have a database storing some confidential information, such
as legal information, medical or financial records,  etc., and a
Web site with a membership system so that only authorized users can
view the information.

I understand I can encrypt the information, and the user's passwords,
so that if the database is compromised it still shouldn't be possible
for an outsider to view the confidential information.

However, what about people who have legitimate access to the database,
such as the DBA, Web developer, etc., but who should not be able to
view the confidential information?  For example, even though the
user's password was encrypted, what would stop the DBA from replacing
the user's password with his own (encrypted) password, then logging in
and viewing the user's info, then copying back the original encrypted
password?  Or, adding a new user for himself with whatever
permissions he chooses?

SQL Server To C++ Or Notepad
Basically I'm working on a Web page in ASP.NET, we the nhave our SQL server database, and inside we have C++ which needs to be able to go through incoming files and perform some operations, as well as enter it into the SQL database, and retrieve information from it. But we haven't the foggiest as how to go about doing thing, our C++ programmer doesn't know how to set up a connection from SQL to his code. IS there A) a program that will convert the SQL data into a text file for him to read from with C++. B) A GOOD book that he can pick up that will help bridge the gap between his knowledge and the knowledge required. So far google hasn't represented much luck. Any advice pertaining to some way to allow our C++ guy to learn/or enable him to read data and insert data into a SQL server would be GREATLY appreciated.

Error When Importing Text File - Saving In Notepad First Works
I'm trying to import a tab separated text file into sql server 2005 using the import guide. But when running the job I get the error message

Error 0xc02020c5: Data Flow Task: Data conversion failed while converting column "Column 19" (67) to column "Column 19" (404). The conversion returned status value 2 and status text "The value could not be converted because of a potential loss of data.".
(SQL Server Import and Export Wizard)

The column 19 which reported a problem contains this information:
?searchroot=/_gen_/txt/&template=std.htm&use=prospect&intref=1_26067

However what is mysterious is that if I open the file in notepad or Excel and resave it again the job runs perfectly. This is not a way we could make it work later on since it's an automatic job that will run each night on a new text file.

The text file is sent from Norway to Sweden - and I use ANSI latin 1 when importing.

The column has datatype DT_STR with a width of 500.

I use Locale Swedish and when I save in Notepad it is saved in ANSI,

I use Windows XP Swedish version.

SQL Injection - How To Prevent It?

Prevent Duplication On UPDATE
Hello
I noticed a spelling mistake in the data in a column of several tables, I used the following syntax to alter the spelling:
UPDATE [dbo].[Prod_Cat]     SET  [ProdName]=N'merseyside'    WHERE ProdName = 'mmserseyside'
The above code correctly updated the spelling error, but it also inserted a new row with the corrected data. 
So I found myself with two Identical rows containing the corrected information. I had to manually delete the extra row. Because if I had put in a DELETE statement, I would have then lost both rows.
What do I need to do to prevent this happening next time.  As I find that I need to update the names of some products, but I don't want to duplicate them.
Thanks

How Do I: Prevent Race Condition?
I want to be able to read and update a value in the database without entering a race condition.
For example:
User #1 reads a row from the database, changes a value then writes the value back.
User #2 reads the same row AFTER user #1 has read it, but BEFORE user #1 writes it back. User #2 then changes the value and writes it back, overwriting the value that user #1 wrote.
I thought I could do this with transactions, but it just makes user #2 wait until user #1 is done writing before user #2 can write. It doesn't stop user #2 from reading while user #1 has it out.
Does that make sense?

How To Prevent SQL Injection Attacks
Hi,

On my site I have a simple textbox which is a keyword search, people type a keyword and then that looks in 3 colums of an SQL database and returns any matches

The code is basic i.e. SELECT * FROM Table WHERE Column1 LIKE %searcg%

There is no validation of what goes into the text box and I am worried about SQL injection, what can I do to minimize the risk

I have just tried the site and put in two single quotes as the search term, this crashed the script so I know I am vunerable.

Can anyone help, perhaps point me in the direction of furthur resources on the subject?

What Are Sql Injection Attacks And How To Prevent?
this is a question I put in the sql community in microsoft, but havent be answered in full

------------

I am using dynamic sql to do a query with differents 'order' sentences and/or 'where' sentences depending on a variable I pass to the sp

ex:

create proc ex
@orden varchar(100)
@criterio varchar(100)

as
declare consulta varchar(4000)

set consulta=N'select pais from paises where '+@criterio' order by '+@orden

------------

I'd like to know it it uses 2 sp in the cache, as I read, the main sp and the query inside the variable of the dynamic sql. if so, as I imagine, then I suppose I have to do the main sp without any 'if' sentence to be the same sp, and so taking it from the cache and not recompile the sp

now, I have various 'if' sentences in the main sp (the caller of the dynamic sql) but I plan to remove them and do the 'if' by program -it is in asp.net-, so I suppose it is better because in this way the main sp is took from the cache, supposing this uses the cache different that the dynamic sql in the variable

what do u think? does the dynamic sql use 2 caches? if so, u think it is better to try to do the main sp same in all uses (no 'if' statements)?


-----

They told me this coding is not good (dynamic sql) because it can give control to the user?

I ask, how does it give control to use? what ar sql injection attack and how to prevent them?

I use dynamis sql because I have 150 queries to do, and thought dynamic sql is good

is it true that dynamic sql have to be recompiled in each execution? I suppose so only if the sql variable is different, right?

can u help me?

Trigger To Prevent Duplicates
Hi all,

I'm writing a trigger to prevent duplicates. I know that this can be done through primary key or unique constraints but in the real world my uniqueness is defined by 8 columns which is too a big an index to maintain on the primary / unique key.

If I create a table with 2 columns

CREATE TABLE Table1
(CentreCHAR(10),
Month CHAR(3)
)


Then create a trigger to prevent duplicates

CREATE TRIGGER trigger_Check_Duplicates
ON Table1
FOR INSERT, UPDATE
AS
-- This trigger has been created to check that duplicate rows are not inserted into AudioVisual table.
DECLARE @IsDuplicate INTEGER
-- Check if row exists
SELECT @IsDuplicate = 1
FROM Inserted i, Table1 t
WHERE t.Centre = i.Centre
AND t.Month = i.Month
IF (@IsDuplicate = 1)
-- Display Error and then Rollback transaction
BEGIN
RAISERROR ('This row already exists in the table', 16, 1)
ROLLBACK TRANSACTION
END

Then insert a row into the new table (no other data is in there)

INSERT Table1
VALUES('0691040176','AUG')

I get the Trigger error message that the row already exists. Why is this the case? I though that Table 1 (target table) would show no entries as it has no data - it should be a before image of the table and the inserted table should be an after image.


Please help!!!

Prevent MS Access To Connect
Hello
 
I'm facing a dilemma. I have quite a lot of users who need read access to data for analysis purposes. By granting them read access you also give them the option to connect to the database using MS Access which puts locks on the data.
 
First I thought of generating stored procedures for all tables within a database those users need to query but when users execute a stored procedure with the name of the table, they get a resultset of all the data. They cannot filter the data by for example using select top 100* from usp_table where name like '%worf%'
 
I'm sure I'm not the only one here but I don't see any alternative then grant them those rights.
 
Thanks!

Is It Possible To Prevent Databases From Being Copied?
Hi,

We have a point of sale application (C# .NET 2.0) and a Sql Server 2005 database back end.

Our customers are concerned that employees could create a backup of the SQL Server database (or even of the MDF file) and use it to steel customer data.

Very often, the application is running on a single PC in a shop using Sql Server Express Edition 2005 under Windows XP. The users usually log on as local administrator. It's hard for us to force our customers to change their local security policies.

Ideally, I would like some form of security mechanism that prevents a backup from being restored on to another PC without either a password or some other form of authentication.

Is this possible?

How To Prevent A Distributed Transaction?
I have a stored proc that performs some validations and returns a result set.  I catch the result set in a calling procedure as follows:
 
declare @tblErr (ErrType varchar(20), ErrMsg varchar(255))
insert @tblErr (ErrType, ErrMsg)
    exec dbo.spMyProc ...(args)
 
Within the def of spMyProc there is a cross-server call:
 
create procedure dbo.spMyProc (...params...)

as
begin

declare @tblErr (ErrType varchar(20), ErrMsg varchar(255))

...(do checking, inserts to @tblErr)...
 
-- check other server
exec @n = otherserver.mydb.dbo.spCheck ...(args)
if @n != 0
    insert @tblErr values ('someerr', 'somemsg')
...etc.
select ErrType, ErrMsg from @tblErr
end

 
Apparently, the implicit transaction of the outer Insert statement is causing a distributed transaction to be started.  There is no 'begin tran', distributed or non, and the foreign sp has no data-modifying statements.  The call to spMyProc, if done from a query window, works fine, returning the desired resultset.  When called from the outer proc, the call fails because the servers are not configured for distributed transactions.  When performed without the cross-server call, using a copy of the remote db attached to the local server, the outer proc works fine.
 
I do not want a distributed transaction.  How can I prevent one?  The local server is 2005 Standard on Server 2003, and the linked server is SQL2000 on Windows 2000 Server.

How To Prevent A Second Entry Being Inserted With Primary Key Value? (C#)
Ok, this is a really stupid question, but I can't seem to find an answer I understand. In my SQL database I have a a table called MasterSkillList, to which the user can write by using a little web form with a text box and a drop down list. The table has 2 fields, Skill and Attribute. Skill is the primary key, as no skill can appear twice. What I want to do is prevent just that, I don't want people to enter the same skill more than once. So how do I tell the user that the entry allready exists in the database?
 My C#  Code is as follows:1 protected void btnSubmit_Click(object sender, EventArgs e)
2 {
3 srcAddSkill.InsertParameters["Skill"].DefaultValue = txtSkillName.Text;
4 srcAddSkill.InsertParameters["Attribute"].DefaultValue = ddlAbility.SelectedValue;
5 try
6 {
7 srcAddSkill.Insert();
8 lblErrorMessage.Text = "The skill '" + txtSkillName.Text + "' has been added. It is based on a character's " + ddlAbility.SelectedItem + " score.";
9 lblErrorMessage.Visible = true;
10 txtSkillName.Text = "";

Prevent Duplicate Entries In A Table
I have an ASP.Net Web appplication with a Back-End SQL DB. There are 3 Tables; Users, Groups, and GroupMember.

The GroupMember table is used to link Users to Groups and consists of just two fields; userID and GroupID.

Here is a sample of some data:

User1 Group1
User1 Group2
User2 Group2
User3 Group1
User3 Group3

Users can belong to multiple Groups. However, you shouldn't be able to have the same user and group comobination more than once. for example:

User1 Group1
User2 Group2
User1 Group1

I can stop this kind of duplicate data entry by doing a lookup first (using asp.net) to see if the entry already exists but this seems cumbersome.

Is there a simpler way to prevent duplicate entries in a table using sql?

Thanks a lot,

This serial can be in the table many times with any other comboso for e.g.The table could contain 100 entries for serial column value '123456'with testresult value 'FAIL', 'PENDING' etc.** TESTED SCHEMA BELOW **-- create tableCREATE TABLE bstresult(ID int IDENTITY (1, 1) NOT NULL ,serial char (10) NULL ,testresult char (10) NULL)-- Insert valid valuesinsert into bstresult values ('123456','PASS')insert into bstresult values ('123456','FAIL')insert into bstresult values ('123456','FAIL')insert into bstresult values ('123456','PENDING')-- insert invalid value this should failinsert into bstresult values ('123456','PASS')If I simply create a unique constraint on both columns it will notallow the FAIL combo or PENDING combo with the same serial which I needto allow.Appreciate your help.

DTS Package - How To Prevent A 0 Byte File?
I've created a DTS package -- that uses a query to export to a .txt file. My question is -- if the results of this query are zero (no results returned within the package ) -- how can I tell the package not to export a zero byte file. Any thoughts on that? Any help you could give would be greatly appreciated. Thanks!
