SQL> problem | |
Problem 2 | |
Select statements can have an additional clause called the 'where' clause. | |
This lets us extract specific rows out of our table. Our where clause can be | |
specific enough to match a single row, or general enough to match a set of | |
rows. The format of a select statement with a 'where' clause is: | |
SELECT <column list> FROM <table name> WHERE <equality expression>; | |
Examples: http://sqlzoo.net/wiki/SELECT_basics -- 1 | |
Task: Write a query that shows all the information about all salespeople from | |
the 'Northwest' region. | |
SQL> tables | |
The following tables are available: | |
salespeople | |
melons | |
customers | |
orders | |
order_items | |
SQL> select * from salespeople where region='Northwest'; | |
