Final Answer:
To enable the storage of a maximum width of two characters in the Job_class column of the EMPLOYEES table, execute the appropriate SQL command to modify the column width.
Step-by-step explanation:
Altering Column Width:
To modify the width of the Job_class column in the EMPLOYEES table, the appropriate SQL command is needed. The SQL command typically takes the form of an ALTER TABLE statement that specifies the table name, column name, and the new width constraint.
Example SQL Command:
An example SQL command for Oracle Database might be:
ALTER TABLE EMPLOYEES
MODIFY Job_class VARCHAR2(2);
This command alters the EMPLOYEES table, modifying the Job_class column to allow a maximum width of two characters.
Verification and Considerations:
After executing the SQL command, it's advisable to verify the changes and consider potential impacts on existing data and application functionality.
Therefore, to achieve the specified modification, execute the appropriate SQL command to alter the width of the Job_class column in the EMPLOYEES table.
