Oracle Database Interview Question:

How To Use "IF" Statements on Multiple Conditions?

Submitted by: Administrator

If you have multiple blocks of codes to be executed based on different conditions, you can use the "IF ... ELSIF" statement. Here is a sample script on IF statements:

DECLARE
day VARCHAR2;
BEGIN
day := 'SUNDAY';
IF day = 'THURSDAY' THEN
DBMS_OUTPUT.PUT_LINE('Checking log files.');
ELSIF day = 'TUESDAY' THEN
DBMS_OUTPUT.PUT_LINE('Helping developers.');
ELSIF day = 'FRIDAY' THEN
DBMS_OUTPUT.PUT_LINE('Rebuild indexes.');
ELSE
DBMS_OUTPUT.PUT_LINE('Reading some papers.');
END IF;
END;

This script should print this:

Reading some papers.
