Answer #1

Ans:

actor table contains the attributes id and name and id is primary key.

SELECT name FROM actor WHRE name LIKE 'M%';

Above query give the result from the actor table whose name starts with the 'M'.

LIKE operator is used to comparing the strings.

here name is compared with the 'M%' this means starts with 'M' and '%' represents matches any substring.

example:

suppose actor table contains values of name with Madhu,Manasa,Sai,Raghava.

result will be Madhu and Manasa.

Thank you!
