3) MODIFY column in the table
The MODIFY command is used to change the column definition of the table.
Syntax:
ALTER TABLE table_name
MODIFY column_name column_definition
[ FIRST | AFTER column_name ];
Example:
In this example, we modify the column cus_surname to be a data type of varchar(50) and force the column to allow NULL values.
Use the following query to do this:
ALTER TABLE cus_tbl
MODIFY cus_surname varchar(50) NULL;
