Each row must be able to stand on its own, without a dependency to other rows in the table. The row must represent a single, complete instance of the entity the table was created to represent. Each column in the row contains specific attributes that help define the instance. This may sound a bit complex, but it is actually very simple. To help illustrate, consider a real-world entity, such as an employee. If you want to store data about an employee, you would need to create a table that has the properties you need to record data about your employee.
With a varchar data type on a table column, the data is stored physically in the row with the rest of the data. With a text data type, the data is stored separately from the actual row and a pointer is stored in the row so that SQL Server can find the text. The text data type is functionally equivalent to the varchar(MAX) data type. nchar 2 bytes per character. Maximum 4000 characters (8000 bytes). The nchar data type is a fixed-length type identical to the char data type, with the exception of the number of characters supported.
Tables Tables are divided up into rows and columns. Each row must be able to stand on its own, without a dependency to other rows in the table. The row must represent a single, complete instance of the entity the table was created to represent. Each column in the row contains specific attributes that help define the instance. This may sound a bit complex, but it is actually very simple. To help illustrate, consider a real-world entity, such as an employee.
