http://en.wikipedia.org/wiki/SQL_injection[^]

SQL injection is a technique often used to attack data driven applications. This is done by including portions of SQL statements in an entry field in an attempt to get the website to pass a newly formed rogue SQL command to the database (e.g., dump the database contents to the attacker).

https://www.owasp.org/index.php/SQL_Injection[^]

A SQL injection attack consists of insertion or "injection" of a SQL query via the input data from the client to the application. A successful SQL injection exploit can read sensitive data from the database, modify database data (Insert/Update/Delete), execute administration operations on the database (such as shutdown the DBMS), recover the content of a given file present on the DBMS file system and in some cases issue commands to the operating system. SQL injection attacks are a type of injection attack, in which SQL commands are injected into data-plane input in order to effect the execution of predefined SQL commands.

Use parameterized queries;
Don't use dynamic SQL, use parameterized queries;
Oh, and did I mention: use parameterized queries!

Input validation and other techniques have their place, but the only way to completely avoid SQL injection is to use parameterized queries. If you ever find yourself concatenating strings (other than known constant strings) to build a query, either in client code or a stored procedure, you've left yourself open to SQL injection.

Calculation For Time Attendance System

i had plot data from Entry Pass Scan in / out system into Database and write calculation in SQL script to generate Report in Aspx web page.

i had different type of shift pattern following by

EP_SHIFT_NAME EP_SHIFT_DESC EP_SHIFT_TIMEFR EP_SHIFT_TIMETO R1 Off Day 09:00 23:59 W1 W1 08:00 17:00 R2 Rest Day 09:00 23:59 D1 Day Shift 07:00 16:00 NS Normal Shift 08:00 17:30 E1 Day Shift 08:00 17:00 E2 Night Shift 20:00 05:00 N1 Night Shift 19:00 04:00

Currently i had facing a problem which is

a)Total actual working minute(as Work MIn) is 720min per day[12 hours per day] (if more than 720 minutes working hours is consider under category Extra OT hour).

b) Cut off the scan in and out time from 0700 ~ 1900 (DAY) and 1900 ~ 0700(NIGHT) calculation.

However, if the person late in or early out the calculation of the time is base from the last and the first scan.

Anyone can help me or amend the calculation in SQL Script ?

For the Work Hour calculation, i have a idea which is catch the (last scan time - EP_SHIFT_TIMEFROM) for every shift type

Kindly advise , thank you

You are seriously hoping someone will go through that heap of... good luck with that. Try breaking it down to smaller bits that you can work over in isolation and then put the bits together to solve the issue or at least isolate the problem.

Loading in a dump like that is not going to get you a positive response.

Enable the TCP/IP protocol (see configuration).
Open port 1433 on your firewall.
Setup port forwarding on your router.

..and start praying; a SQL Server directly connected to the internet is a bad idea. Expect quite some people poking the server to check its security.

The "best" way to expose your database would be by using webservices Smile | :)

SQL Server 2012 - forming relationship between tables

RickBStewart2-Jul-13 10:53

RickBStewart

2-Jul-13 10:53

This is my first database project and I am having difficulties forming the correct relationship between two tables. The database is storing inventory records for approximately 20 buildings, and the room numbers in many of the building are numbered the same.

One table has columns like Asset Number, PO Number, Equipment Type, Manufacturer, Model Number, Serial Number. The PK is the Asset Number.

The second table has Building Name, Room Number, Room Type, Staff Name. The key for this table is a combination of Building Name and Room Number. I need both to uniquely identify the location.

My question is, how do I go about creating the relationship between the tables. The relationship would be described as each Asset having a unique Building/Room Number, but each Building/Room Number can have many Assets.

When I try to create the one-to-many relationship it tells me "Both sides of a relationship must have the same number of columns"

All of the primary key columns from the table on the "one" side need to be present in the table on the "many" side. In this case, you would add both building name and room number to your assets table, and specify both columns in the FOREIGN KEY relationship.

I'd be inclined to move the buildings out to a separate table with a surrogate key, since the value is likely to be repeated across many rows in the rooms table. Similarly, room type and staff name might be better in their own lookup tables, depending on your data.

Buildings
---------
BuildingId (PK)
BuildingName

Rooms
-----
BuildingId (PK, FK->Buildings)
RoomNumber (PK)
...

Assets
------
AssetNumber (PK)
BuildingId (FK->Rooms)
RoomNumber (FK->Rooms)
...

Thank You Richard, I will take your suggestion and do a bit of experimentation. It's clearly the case that a few hours of video at an online training site has not fully educated me. LOL... But it may be enough to get me through this project. I will try and find ( and study ) some documentation on database theory when I get a chance. But until then... Thanks

As a STRONG suggestion you should devote a couple of days to a basic database design book. The consequences of getting your data structure wrong will cost you many multiples of that investment down the track.

Depending on the criticality of the project I would even consider getting a professional to do the basic DB design. There is also a site with sample schemas (I have lost the link) that will give you some excellent pointers.

To somewhat piggy-back on the previous suggestions, I would recommend that you consider using an Identity column for your Primary Key and then using the PK to accomplish the links beween tables.

For Example:

Table: Buildings
BuildingID [int] Primary Key Identity (1-1)
BuildingName [VarChar] (25)
...

Table: BuildingRooms
BuildingRoomID [int] Primary Key Identity (1-1)
BuildingID INT
RoomName [Varchar] (10)
...

Table: Assets
AssetID [int] Primary Key Identity (1-1)
AssetNumber [varchar] (25)
AssetName [VarChar] (50)
BuildingRoomID [int]
...

By using using the Identity columns for the PK's of the tables, you can make your joins much more easily. You may also want to add some Unique Indexes on, for instance, the BuildingName, RoomName, and AssetNumber columns just to make sure someone doesn't accidentally add those items multiple times.

Check out the following link regarding what is termed "normalization" . . . which is what we have suggested with regard to your tables. Wink | ;-)

I've spent some time looking into normalization and currently my tables should be in 3rd Normal Form. I also have my application talking to the remote SQL server via the Entity Framework, so I'm getting there. Thanks all for your suggestions, they were most helpful.

This is the database-forum. What does your question have to do with databases?

FWIW, you'd also need to explain which type of GUI you're building; ASP.NET, WinForms, WPF, Gtk# - otherwise you'll be getting answers that assume the wrong technology.

If you define a database as something that stores data, then by all means Access is indeed a database. It even stores data in a relational format and therefore qualifies to be called a Relational database as well.

Date difference with total years, months and days

How can I obtain total number of years, months and days between 2 dates in a single sql query.

eg :

date1 = 2012-07-02
date2 = 2013-09-04

difference between date1 and date2 should show as "1 year, 2 months and 2 days"

Datediff function returns difference only by years or months or days etc...how can i do that

That's usually not done at the SQL-level, but in code. The SQL-statement would return the difference (just subtract one from the other). It's a bad idea to format data in Sql.
