4. Queries in musicdemo.mdb
Question: Which artists are musical groups?
Under OBJECTS, select Queries, then the NEW button, and then Design View. 
Then ADD the tbl_Artists table, and CLOSE the Show Table window.
Enter the criterion in the Criteria row of the Design Grid. (In Access, =Yes and =True both work for Yes/No fields; =1 only sometimes works)
Save your query as qry_day03_groups

5. Queries Exercise: Design View
Construct queries that:
List only the track title, album ID and duration of the tracks in the collection [>376] (qry_day03_tracklength)
List titles of all albums produced in [>4] (qry_day03_1996_albums)
List the track titles and associated album IDs in the collection that run over 4 minutes [>64] (qry_day03_long_tracks)
Compare the SQL generated by Access to that we created on day 2

7. Complex Criteria Queries
Boolean Operators
AND / OR in Design View
Same line: AND; different lines: OR
Can mix and match: all ANDs grouped together, sets of ANDs are ORed
NOT
Type in criteria field, use NOT(condition)
Other Criteria Keywords
LIKE (and wildcard * in Access)
IS NULL / IS NOT NULL
BETWEEN … AND …
Type these directly into the criteria field in Design View
