لان المشكلة عندي انه يوجد اختلاف احيانا فى الاسئلة بالنسبة ل testking and actualtests
فلا اعرف حل سوى طرحى السؤال فى المنتدي

وهذا هو سؤالي :
Question 191 :
which two statements about subqueries are true ? (choose two)
A- a single row subquery can retrieve data from only one table.
B- a sql query statement cannot display data from table B that is
refered to in its subquery , unless table B is included in the main
query's from clause .
C- A sql query statement can display data from table B that is
refered to in its subquery , without including B in its own FROM
clause .
D- A single row subquery can retrieve data from more than one table
E- A single row subquery can not be used in the condition where the like
operator is used for comparison .
F- A multiple - row subquery can not be used in an INSERT statement to
insert multiple rows at a time .
