Note carefully, however, that fairly complicated things can be scalar values! ) geometric points and line segments are legitimately regarded as scalar values. Make sure the students understand the difference between components of a type per se and components of a possible representation for a type. " Regarding possreps: The distinction between physical (or actual) and possible representations is much blurred in the industry (especially in SQL), but it really ought not to be.

Consider: DECLARE CURSOR C1 FOR SELECT S# FROM SP ORDER BY S# ... " stands for a FOR UPDATE clause -- excluded */ /* here because it isn't discussed in the chapter */ OPEN C1 ; FETCH C1 ... ; DELETE SP WHERE CURRENT OF C1 ; Which specific SP row is deleted? The standard doesn't say! (Specifically, it doesn't say it's the row the cursor is positioned on. ) Another point you should be aware of, though again I wouldn't mention it unless asked: SQL tables can have duplicate column names!
