![]() ![]() Now, while inserting values into the table: INSERT INTO Character_type (X,Y) And the length of any string assigned to X and Y can be a maximum of 1 character and 10 characters. Here, you are creating a Character_type table, in which the variables are Id, X, and Y. Hence, the datatype is used along with the CREATE statement. You have to assign the data type to a variable while creating a table. And n represents the maximum length of a string which can be used as the variable_name. Here, variable_name is the name of the variable which should be of char datatype. The following character data types can be used interchangeably. This length value can be specified as a parameter of the Char or Character type.Ĭhar datatype is a fixed-length data type i.e., so if there is any remaining space then it is padded with blanks.
