7. This query joins the Item and Reservation tables to produce
a list of books where there are ten copies or less and more
than 50 reservations.
Sample Output
SELECT ti.title_no
, ti.title
, rs.isbn
, COUNT(*)
FROM Title ti
JOIN item itm ON ti.title_no = itm.title_no
JOIN reservation rs ON rs.isbn = itm.isbn
WHERE
11 > (SELECT count(cp.copy_no)
FROM copy cp
WHERE cp.isbn = itm.isbn)
AND itm.isbn IN (SELECT DISTINCT rs1.isbn
FROM reservation rs1
WHERE 50 < (SELECT COUNT(*)
FROM Reservation rs2
WHERE rs1.isbn = rs2.isbn))
GROUP BY ti.title_no, ti.title, rs.isbn
ORDER BY ti.title_no

8. This script loads the Date Dimension of an Analysis Services
staging database. This script could easily be converted into
a Stored Procedure with Start and End date parameters.
USE B4_TeamE_Staging
go
DECLARE @StartDate As Datetime,
@EndDate As Datetime
SET @StartDate = '1/1/2002'
Sample Output
SELECT @EndDate = CONVERT ( varchar(20) , MAX(CreationDate), 101 ) FROM Applicant
PRINT 'Start Loop'
WHILE @StartDate <= @EndDate
BEGIN
INSERT INTO dimDate (CreationDate
,Year
,WeekEnding
,MonthValue
,MonthDesc
,QtrValue
,QtrDesc)
VALUES( @StartDate,
year(@StartDate),
@StartDate + ( 7 - datepart(weekday,@StartDate)),
-- Compute Weekending Date
Convert(Varchar(5),year(@StartDate)) +
Right(('0'+ convert(Varchar(50),datepart(m,@StartDate))),2),
-- ex. 200501, 200502..
datename(m,@StartDate), -- set name of the month
Convert(Varchar(5),year(@StartDate)) +
Convert(Varchar(4),datepart(q, @StartDate)),
-- ex. 20051, 20052, 20053, 20054
Datename(yyyy,@StartDate) + ' Q' + datename(q,@StartDate) -- ex. 2005 Q1...
)
SET @StartDate = Dateadd(d,1,@StartDate)
PRINT @startdate
END
PRINT 'End Loop'

10. This ETL process imports multiple CSV files containing Job Time Sheets and
loads them into a staging database. Upon completion, a status email is sent
indicating job statistics and if errors occurred the error log file is attached.

11. This data flow task for the Job Time Sheets package processes
through a single CSV file doing multiple lookups to ensure
database integrity. It logs any rows that error out for review
and correction.
