SELECT x FROM T WHERE y = 0(a) The statement is used as the basis of the declaration of a cursor named Z. Assuming the cursor is declared INSENSITIVE, what happens when it is opened? (b) Give a FETCH statement that causes the value of x in a row of the result set to be placed in host variable w. (c) a KEYSET DRIVEN cursor. What happens when a KEYSET DRIVEN cursor is opened? Describe a situation in which such a cursor behaves di erently then the cursor of (a). (d) Suppose y is a key and we wish to execute the statement using static SQL without declaring a cursor. As before, the value of x is to be placed in host variable w. Give the static SQL statement. e) Suppose the SELECT statement is constructed at run time and stored in host variable v (of type string). As before, y is a key, the value of x is to be placed in w, and no cursor is to be used. Give the dynamic SQL statements that cause this to happen (f) The reference to w is handled di erently in static and dynamic SQL (parts (2d) and (2e)). Explain why.
