Which of the following queries return the names of programs (without duplication) defined in the currently-connected schema whose source contains a call to DBMS_OUTPUT.PUT_LINE (assume that this program name does not appear inside comments)?
SELECT name FROM USER_DEPENDENCIES WHERE referenced_name = 'DBMS_OUTPUT.PUT_LINE'
SELECT name from ALL_SOURCE WHERE owner = USER AND name = 'DBMS_OUTPUT.PUT_LINE'
SELECT DISTINCT name from ALL_SOURCE WHERE INSTR (text, 'DBMS_OUTPUT.PUT_LINE') > 0
SELECT DISTINCT name from USER_SOURCE WHERE INSTR (UPPER (text), 'DBMS_OUTPUT.PUT_LINE') > 0
