In sql, which of the following is applicable to the CHAR datatype?

• CHAR stores alphanumeric characters of fixed size
• Stores alphanumeric characters of variable length
• to create scripts containing infinite characters
• Type as many characters as you want 

 

EXPLANATION

The only difference between CHAR and VARCHAR2 is that CHAR stores fixed-length alphanumeric characters, between 1 and 2000 bytes or characters. If you are stored in the JUNIOR surname in a CHAR (50) column, a column will contain a JUNIOR string + 44 whitespaces that are automatically added to the total column volume.
