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.
Minimum means it's the least and maximum is the most
The definition of maximum in regards of math is the biggest number in the set of numbers / data.Example:If you have the numbers 10,5,8,2,60,9,3,and 1 the maximum in this set of numbers/data is 60. How? It is 60 because in the set of numbers/data it is the highest number in the set.The word maximum in maths means the most or limit.

In a database we can create 255 maximum redo log files Depends on what you specified for MAXLOGFILES during database creation (manually) or what you specified for "Maximum no. of redo log files" with DBCA. sri

how to connect the rad to db2
The DB2 is owned by Aston Martin.
Char is fixed length, while Varchar is variable length.
The CHAR datatype uses a fixed length, where as the VARCHAR datatype can be variable in length up to the maximum value specified for the length. If you insert "Hello" into a CHAR(10) field, the column would actually contain "Hello " with 5 trailing spaces. The same value inserted in a VARCHAR(10) field would contain "Hello". char datatype is fixed length data type and it store maximum 255 characters while varchardatatype store up to 4000 character of variable length datatype
Yes, DB2 install is available for PCs (Windows)
CREATE TABLE `test`.`users` ( `id` INT NOT NULL auto_increment , `name` VARCHAR( 20 ) NOT NULL , `password` VARCHAR( 20 ) NOT NULL , `email` VARCHAR( 20 ) NOT NULL , PRIMARY KEY ( `id` ) )
That is text where we put only character type value and that is varchar where we put all data type value
The difference between varchar and nvarchardatatypes is that Nvarchar stores UNICODE data. If you have requirements to store UNICODE or multilingual data, nvarcharis your choice. Varchar stores ASCII data and should be your data type of choice for normal use.
In DB2, a user is an individual who is granted permissions to access and interact with the database, while a schema is a named collection of tables, views, procedures, and other database objects owned by a user. Users are associated with schemas to define their default schema for objects they create.
