Of course, you can run SQL functions in SQL statements. But many SQL functions can also be executed in regular PL/SQL statements, as shown in the following sample script:
DECLARE
now DATE;
id NUMBER;
str VARCHAR2(40);
BEGIN
now := SYSDATE;
DBMS_OUTPUT.PUT_LINE('Time #1 = ' ||
TO_CHAR(now,'HH24:MI:SS'));
SELECT SYSDATE INTO now FROM DUAL;
DBMS_OUTPUT.PUT_LINE('Time #2 = ' ||
TO_CHAR(now,'HH24:MI:SS'));
id := UID;
DBMS_OUTPUT.PUT_LINE('User id #2 = ' || TO_CHAR(id));
SELECT UID INTO id FROM DUAL;
DBMS_OUTPUT.PUT_LINE('User id #2 = ' || TO_CHAR(id));
str := CHR(70)||CHR(89)||CHR(73);
DBMS_OUTPUT.PUT_LINE('String #1 = ' || str);
SELECT CHR(70)||CHR(89)||CHR(73) INTO str FROM DUAL;
DBMS_OUTPUT.PUT_LINE('String #2 = ' || str);
END;
/
Time #1 = 21:41:16
Time #2 = 21:41:16
User id #2 = 33
User id #2 = 33
String #1 = FYI
String #2 = FYI
