The standard five functions are COUNT, SUM, AVG, MIN, and MAX, and many DBMS vendors provide additional nonstandard functions as well One could report the count of students in each club this way: SELECT Cname, COUNT(*) AS Membership FROM ClubMembership GROUP BY Cname ORDER BY Cname; COUNT(*) says count the occurrences of rows The AS Membership phrase sets the column heading for the counts in the report to Membership The GROUP BY phrase tells SQL how to break down the calculations when using the built-in function; that is, count rows (members) for each club If there were clubs that no students had joined, and one wanted to include that information in the report, one could use an outer join along with the built-in count function to achieve the desired report: SELECT ClubCname, COUNT(ClubMembershipCname) AS Membership FROM Club LEFT JOIN ClubMembership ON ClubCname = ClubMembership.

Cname GROUP BY ClubCname ORDER BY ClubCname; Here a left join on Club and ClubMembership insures that all clubs are included in the report, even if the clubs have no members (no entries in ClubMembership) Also, since Cname is a column heading in both tables, each reference to Cname must also specify which table is being referenced This query says to execute an outer join on Club and ClubMembership so that all clubs are included, and then count the occurrences of records for each club by grouping on club names..

void removeLast(Node list) // precondition: the specified list has at least two nodes; // postcondition: the last node in the list has been deleted; For example, if list is {22, 44, 66, 88}, then removeLast(list) will change it to {22, 44,

If one wanted to report the revenues for each of the clubs, this query using the SUM function would work: SELECT CMCname, SUM( CDues ) AS Revenue FROM ClubMembership CM JOIN Club C ON CMCname = CCname GROUP BY CMCname; This statement introduces the use of aliases for table names In the FROM clause one may follow the name of the table with an abbreviation In that case, the abbreviation may be used wherever the table name would otherwise be required, even in the beginning of the SELECT clause before the FROM clause is encountered! Most experienced SQL people make extensive use of table aliases to reduce the size of SQL statements and make the statements easier to read SQL queries can also be nested, one within another.

The triode input characteristics of Fig. 4-13(a) show that operation with a positive grid voltage results in ow of grid current; however, with a negative grid voltage (the common application), negligible grid current ows and the plate characteristics are reasonably approximated by a three-halves-power relationship involving a linear combination of plate and grid voltages: iP vP vG 3=2 4:9

Note that the new list must be completely independent of the specified list. Changing one list should have no effect upon the other. 3.6 Write and test this method:

where denotes the perveance (a constant that depends upon the mechanical design of the tube) and is the ampli cation factor, a constant whose signi cance is elucidated in 7 when small-signal ampli cation of the triode is addressed. To establish a range of triode operation favorable to the signal to be ampli ed, a quiescent point must be determined by dc bias circuitry. The basic triode ampli er of Fig. 4-14 has a grid power supply VGG of such polarity as to maintain vG negative (the more common mode of operation). With no input signal vS 0 , application of KVL around the grid loop of Fig. 4-14 yields the equation of the grid bias line, iG VGG vG RG RG 4:10
