1. Check your re_HouseSale table : ( week 10 Homework )

SaleDate must be Date

Price must be a number

2. Randomize SaleDate in re_HouseSale table in your database :

200 records 60 Month forward,

150 records 75 Month forward,

170 records 8 years back,

300 records 5 years back.

HINT : use date_add() and date_sub() functions, use “limit 200” to specify number of records,

update records with year (sales_date) = 2008 only

example:

update re_HouseSale set SaleDate = date_add( SaleDate, interval 5 year)

where year(SaleDate) = 2008 limit 200;

3. Display the number distinct ( unique) years in your re_HouseSale table.
