Loops are used to repeat execution of a statement or a set of statements multiple times on base of a condition or expression
EXIT and EXIT-WHEN keywords are used to terminate the loop
EXIT- terminates the loop unconditionally and passes control to the next statement after the loop
EXIT-WHEN- terminates the loop when EXIT-WHEN clause is checked and if returns true then the loop is terminated and control is passed to next statement after the loop
The basic syntax of Loop in PL/SQL is like this
LOOP
Set of statements
END LOOP;
