Answers to questions related to software engineering concepts and PL/SQL programming.

Inline view is a virtual table created in the FROM clause of a SQL query.
Views can be secured by granting appropriate privileges to users and implementing row-level security.
BULK COLLECT is a feature in PL/SQL that allows fetching multiple rows from a query into a collection.
PL/SQL program to display weekdays except Saturday and Sunday: DECLARE v_day VARCHAR2(20); BEGIN FOR i IN 1..7 LOOP v_day := TO_CHAR(SYSDATE + i, 'DAY'); IF v_day NOT IN ('SATURDAY', 'SUNDAY') THEN DBMS_OUTPUT.PUT_LINE(v_day); END IF; END LOOP; END;
ROWID is a unique identifier for a row in a database table, while ROWNUM is a pseudo-column that represents the row number in a result set.
Global variables have a scope throughout the entire program, local variables have a scope within a specific block or subprogram, and bind variables are used in SQL statements to pass values from the application to the database.
