7. Consider the basic syntax of UPDATE statement as given below. How can we ensure with this syntax that at most one record is updated? [1 mark] UPDATE some Table SET someColumn = someValue WHERE someCondition ; Q8 (1 point) 8. Consider the following UPDATE statement. When executed an error occurred. "some Table" has no inward/outward foreign key constraints, "someColumns" is varchar(20) and "someOtherColumn" is INT. What could possibly go wrong? [1 mark] UPDATE some Table SET someColumn = 'Adam' WHERE someOtherColumn > 5; 7. Consider the basic syntax of UPDATE statement as given below.
