Task 3:

The Driver Relationship team wants to create some workshops and increase communication with the active drivers in InstantRide. Therefore, they requested a new database table to store the driver details of the drivers that have had at least one ride in the system. Create a new table, ACTIVE_DRIVERS, from the DRIVERS and TRAVELS tables which contains the following fields:

DRIVER_ID CHAR(5) (Primary key)
DRIVER_FIRST_NAME VARCHAR(20)
DRIVER_LAST_NAME VARCHAR(20)
DRIVER_DRIVING_LICENSE_ID VARCHAR(10)
DRIVER_DRIVING_LICENSE_CHECKED BOOL
DRIVER_RATING FLOAT

SQL Database Test:

Create a new table to store information on active drivers

Test Query: SELECT * FROM ACTIVE_DRIVERS

Expected Results:

DRIVER_ID	DRIVER_FIRST_NAME	DRIVER_LAST_NAME	DRIVER_DRIVING_LICENSE_ID	DRIVER_DRIVING_LICENSE_CHECKED	DRIVER_RATING
2001	Willie	Butler	1874501	1	4.4
2002	Justin	Howard	1953853	1	4.8
2003	Anthony	Walker	1735487	1	3.5

Task 4:

The Driver Relationship team wants to have quick search options for the active drivers. The team specifically mentioned that they are using first name, last name and driving license ID to search the drivers. Create an index called NameSearch on the ACTIVE_DRIVERS table created in task 3.

SQL Database Test:

Create an INDEX to search the ACTIVE_DRIVERS table.

Test Query:

SHOW INDEX FROM ACTIVE_DRIVERS

Expected Results:

Table	Non_unique	Key_name	Seq_in_index	Column_name	Collation	Cardinality	Sub_part	Packed	Null	Index_type	Visible	Expression
ACTIVE_DRIVERS	0	PRIMARY	1	DRIVER_ID	A	3	NULL	NULL		BTREE	YES	NULL
ACTIVE_DRIVERS	1	NameSearch	1	DRIVER_FIRST_NAME	A	3	NULL	NULL	YES	BTREE	YES	NULL
ACTIVE_DRIVERS	1	NameSearch	2	DRIVER_LAST_NAME	A	3	NULL	NULL	YES	BTREE	YES	NULL
ACTIVE_DRIVERS	1	NameSearch	3	DRIVER_DRIVING_LICENSE_ID	A	3	NULL	NULL	YES	BTREE	YES	NULL
