Varchar is the short form for the variable character field. This character represents data of indeterminate length. In an actual sense, varchar refers to a data column type that can be found in DBMS (Database Management Systems). Varchar columns can vary in field size, depending on whatever database is in consideration.

The maximum limit of the field in Oracle 9i is 4000 characters. The data limit for MySQL for a row is 65,535, and the field limit of Microsoft SQL server 2005 is 8000. On the other hand, Nvarchar refers to a column that can store relatively any length of Unicode data. The Nvarchar, however, must adhere to a code-page of 8-bit coding.

While 8000 is the maximum size for varchar, 4000 is the maximum size for Nvarchar. This simply implies that 8000 can be the maximum amount for a single column of varchar, while 4000 characters can be the amount of a single column of Nvarchar at the maximum.

Varchar and Nvarchar are related to computer databases. Varchar may be commonly known for its long-form Variable Character Field. Data is what these characters stand for, and their length is unable to be determined. Varchars are data columns that are found in DMS, which stands for Database Management Systems.

There are up to 4000 characters that can be in the Varchar field, and it has a data limit of 65,535. Nvarchar is a column, and it stores any length of Unicode data. One of the key differences between the two is the number of characters. Ncarchar can contact 4000, while Varchar can contain 8000

If in case you are confused, you should know that Varchar stands for Variable Character Field. These are characters that will also act as the data of the variables with lengths that cannot be computed at this time. You can find Varchar in various database management systems. Most of the time, they would contain up to 4000 characters.

Nivarchar is a type of column that is used to store different types of Unicode data. It does not matter what the length is. It will just store the data that you need. One main difference between the two is their size. Varchar will have a higher maximum capacity at 8000 while Nivarchar will only have a maximum capacity of 4000.

Varchar is a short form for Variable Character Field. These characters stand for data, which length cannot be determined. In the real sense of it, Varchar is a type of data column that is found in DMS -Database Management Systems. The Varchar field can contain up to 4000 characters at maximum in Oracle 9i. The data limit for the row of MySQL is up to 65,535; while the field limit for Microsoft SQL Server 2005 is 8000.

On the other hand, Nvarchar happens to be a column that can store Unicode data at any length. 8-bit coding is the code page that Nvarchar should adhere to. A significant difference between Varchar and Nvarchar is their sizes, of which the former has a maximum capacity of 8000, while the latter has a maximum size of 4000.

This simply means that Varchar's single column can contain up to 8000 characters, while Nvarchar's single column can contain up to 4000 characters at most.
