1 A, B, C, and E Subqueries can be used at all these points D and F A subquery cannot be used in the GROUP BY and ORDER BY clauses of a query 2 D Subquery nesting can be done to many levels A, B, and C A and C are incorrect because subqueries can be nested B is incorrect because the number of rows returned is not relevant to nesting subqueries, only to the operators being used 3 A The result set of the inner query is needed before the outer query can run B, C, and D B and C are not possible because the result of the subquery is needed before the parent query can start D is incorrect because the subquery is only run once 4 D This is a correlated subquery, which must be run for every row in the table A, B, and C The result of the inner query is dependent on a value from the outer query; it must therefore be run once for every row 5 A and D The two statements will deliver the same result, and neither will fail if the name is duplicated B and C B is incorrect because the statements are functionally identical, though syntactically different C is incorrect because the comparison operator used, IN, can handle a multiple-row subquery 6 A and B A scalar subquery can be defined as a query that returns a single value C and D C is incorrect because a scalar subquery is the only subquery that can be used in the SELECT list D is incorrect because scalar subqueries can be correlated 7 E ALL, ANY, IN, and NOT IN are the multiple-row comparison operators A, B, C, and D All of these can be used 8 C The equality operator requires a single-row subquery, and the conditional subquery could return several rows A, B, and D A is incorrect because the statement will fail in all circumstances except the unlikely case where there is zero or one employee B is incorrect because this is not a problem; there need be no relationship between the source of data for the inner and outer queries D is incorrect because the subquery will only run once; it is not a correlated subquery PART II.

.

9 A and B are identical C is logically the same as A and B but syntactically is not possible; it will give an error D will always return no rows, because it asks for all employees who have a salary lower than all employees This is not an error but can never return any rows The filter on DEPARTMENTS is not relevant 10 C If a subquery returns NULL, then the comparison will also return NULL, meaning that no rows will be retrieved A, B, and D A is incorrect because this would not cause an error B is incorrect because a comparison with NULL will return nothing, not everything D is incorrect because a comparison with NULL can never return anything, not even other NULLs 11 D UNION ALL returns rows in the order that they are delivered by the queries that make up the compound query A, B, and C INTERSECT, MINUS, and UNION all use sorting as part of their execution 12 A, B, and C INTERSECT, MINUS, and UNION all remove duplicate rows D UNION ALL returns all rows, duplicates included 13 C All set operators have equal precedence, so the precedence is determined by the sequence in which they occur A, B, and D A and B are incorrect because set operators have equal precedence though this may change in future releases D is incorrect because many set operators can be used in one compound query 14 A = 4; B = 8; C = 0; D = 4 Note that 16 is not used; that would be the result of a Cartesian product query 15 C Every query in a compound query must return the same number of columns A, B, D, and E A is incorrect because the columns can have different names B is incorrect because the two columns are of the same data type group, which is all that is required It therefore follows that D and E are also incorrect 16 B You cannot use ORDER BY for one query of a compound query; you may only place a single ORDER BY clause at the end A, C, D, E, and F All these lines are legal 17 B The rows from each query will be grouped together, but there will be no sorting A, C, and D A is not possible with any syntax C is incorrect because that would be the result of a UNION, not a UNION ALL D is incorrect because UNION ALL will return the rows from each query grouped together.

To stroke a selection and create a quick border, first make sure the color you want the border to be is I like to first create a new layer (choose Layer | visible in the foreground swatch of the New | Layer) on which to place my border so I can toolbox Then, make a selection in an open easily delete or edit it later if needed document in Photoshop with one of the selection tools After making a selection, choose Edit | Stroke to reveal an options window similar to this one:
