Maximum length of a varchar field in SQL Server?
12,500 is the maximum length of a varchar field. The nVarchar field has the same limitation however you will use twice the data store space with an nVarchar as it is effectively the same as a varchar with the exception that it will store data required for international character sets. If you support a multi-language system then you will want to use a nVarchar character type for these fields.

Microsoft SQL Server is a relational database management systemdeveloped by Microsoft. As a database, it is a software productwhose primary function is to store and retrieve d…ata as requestedby other software applications, be it those on the same computer orthose running on another computer across a network (including theInternet). There are at least a dozen different editions ofMicrosoft SQL Server aimed at different audiences and for differentworkloads (ranging from small applications that store and retrievedata on the same computer, to millions of users and computers thataccess huge amounts of data from the Internet at the same time).Its primary query languages are T-SQL and ANSI SQL.
SQL is an abbreviation for Structured Query Language. SQL is a means to request data from a database. SQL is a standards based langage that has many versions approved by the A…merican National Standards Institute (ANSI). There are many versions of ANSI-SQL and most databases support specific versions of ANSI-SQL. SQL Server is a database management system that was originally created by Sybase. Microsoft bought the rights from Sybase to market their own version of SQL Server on the Microsoft Windows operating system. Sybase still has versions of SQL Server on other operating systems. When people refer to SQL Server, they typically mean "Microsoft SQL Server." Microsoft SQL Server is a database management system (DBMS) that utilizes SQL (or more specifically Transact-SQL, or T-SQL) as a means to extract data from it's database tables.
Microsoft SQL Server is an application used to create computer databases for the Microsoft Windows family of server operating systems. Microsoft SQL Server provides an environ…ment used to generate databases that can be accessed from workstations, the Internet, or other media such as a personal digital assistant (PDA).

SQL Server is not an operating System. SQL Server is a databse Package. It is a Sequential Query Language of RDBMS Database e.g. Oracle. It can work with any Operating Syste…m, Windows, Linux etc. It requires access to database.
In the table design view, right click the column name of the entity you want to create a relationship with and then select "Relationships" which opens the Properties window wi…th the Relationships tab selected. Click on "New" and then verify the "Primary key table" and "Foreign key table". Select the primary key from the grid below the "Primary key table" name (left side of grid) and then select the column name you right-clicked on earlier from the grid below the " Foreign key table" name (right side of grid). Selecting each one in turn sets the two into the desired relationship.
SQL has to do with database management.it is the engine which drives the format as to how database management will work.there are triggers which manage the back-end after …an order is made(this usually refers to how the engine works). triggers are used to manage inventory management in a retail outlet a s to how everything is set in place for a retail outlet.SQL has the engine on which back-end programming works(the programs take care of everything you need in order. by vaibhav aksh
SQL Injection is a form of attack on your SQL server, using the vulnerability of your (usually) HTML form handling of your web-application. The most common form is to inject… additional command into your SQL statement. Many programmers are not aware of this common issue. A simple example: you have a HTML form that collect your name. NAME: [text box] [button GO] Many programmer, will program in a way that will translate that input to gather information from the SQL server with an SQL statment: SELECT vdDateOfBirth, viUserID FROM tblUsers WHERE Name='[name]'; So, the SQLInjector attempt to hijack that by type this into the [text box]: '; truncate table tblUsers; // by putting that into the [textbox]; the program will generate this SQL statement: SELECT vdDateOfBirth, viUserID FROM tblUsers WHERE Name=' '; truncate table tblUsers; // '; effectively, when the program execute this statment, the entire tblUser will be deleted!!! This is just a simple example. There are ways to extract the database structure through injection, and by knowing your data structure, have the ability to get user information (ie, password, credit card, etc, etc), and even the SA access; if the sql admin has been slacking .... Thus, it is extremely important that whoever program your web-application is aware of this. but unfortunately, 90% of web programmers are not aware of this flaw. SIMPLE SOLUTION: A very simple solution is that you CLEANSE your data before putting it into an SQL statment, ie in asp: vsInput = Replace( vsInputbox.text, "'", "''") this simple statement will effectively stop the use of the ' character; Alternatively, use parameterized procedure (the best way) but not many people do this.
Well.... in HTML? In PythonCard programs? or just in general? I guess it doesn't really matter, since in any situation where you can specify the size of a text field, it reall…y can be as big as you want. (and in html forms, you specify the size by the number of characters (y'know, letters, numbers, spaces, punctuation marks) wide the text field is.)
There is no simple answer to that. There are a lot of database applications and they would use different sizes. Older versions of the same software would use shorter amounts a…nd future versions will further extend them. They allow hundreds, even thousands of characters. As a general rule though, when entering data into a text field in a database, it should be as specific and simple as possible and so not take up too much space. That will make the data easier to work with.
