+# SQL
2
+
3
+The following lab is to be completed using MySQL in your terminal. 
4
+
5
+To begin import the schema for all of the tables from the following location: 
6
+
7
+`src/main/resources/schema-h2.sql` 
8
+
9
+You must create a database in which to import the schema by accessing mysql through the terminal, then exit and import the schema using: 
10
+
11
+`mysql -u root -p [database] < src/main/resources/schema-h2.sql` 
12
+
13
+Don't submit any changes to the schema file.  And, in all reality, you shouldn't be doing anything in there outside of
14
+experimenting for your own curiosity.
15
+
16
+## Guided Walkthrough
17
+
18
+Proceed through the sections below, testing out the queries shown and observing the result. 
19
+Feel free to experiment with your own variations on these queries. 
20
+This will help to build your familiarity with the process of working with SQL queries.
21
+
22
+#### Insert people into People table
23
+
24
+```SQL
25
+INSERT INTO people (last_name, first_name, mobile, birthday)
26
+VALUES ('Smith', 'John', '230-4293', '1973-01-23');
27
+```
28
+
29
+After doing that insert, go ahead and run all the statements in the `data-h2.sql` file.  That should build out your
30
+database enough to get started.  Feel free to add more people, though.
31
+
32
+My suggestion for the following stuff is, in the H2 console, leave the first line as a `SELECT *` from whatever tables
33
+you're querying.  Then, after that, run your queries.  That way you can compare the results of your query with the 
34
+data in the table.
35
+
36
+#### Selecting all rows from table 
37
+
38
+```SQL
39
+SELECT * FROM people;
40
+```
41
+
42
+#### Updating rows
43
+
44
+Update firstname for person whose id is 1
45
+
46
+```SQL
47
+UPDATE people SET first_name = 'Tony' WHERE id = 1;
48
+```
49
+
50
+Update mobile where last names are Smith
51
+
52
+```SQL
53
+UPDATE people SET mobile = '152-9854' WHERE last_name = 'Smith';
54
+```
55
+
56
+Update multiple columns with multiple conditions
57
+
58
+```SQL
59
+UPDATE people SET birthday = '1955-01-25' 
60
+WHERE last_name = 'Smith' 
61
+AND id = 4;
62
+```
63
+
64
+```SQL
65
+UPDATE people SET mobile = '333-3333', last_name = 'Johnson' 
66
+WHERE first_name = 'Noelle' OR first_name = 'Raj';
67
+```
68
+
69
+#### Basic Functions
70
+
71
+```SQL
72
+SELECT * FROM people;
73
+```
74
+
75
+```SQL
76
+SELECT COUNT(homenumber) FROM homes;
77
+```
78
+
79
+```SQL
80
+SELECT homenumber FROM homes WHERE id = 1;
81
+```
82
+
83
+```SQL
84
+SELECT COUNT(*) FROM homes;
85
+```
86
+
87
+```SQL
88
+SELECT COUNT(DISTINCT last_name) FROM people;
89
+```
90
+
91
+```SQL
92
+SELECT  SUM(id), AVG(id) FROM people;
93
+```
94
+
95
+```SQL
96
+SELECT SUM(id) AS sum, AVG(id) AS avg FROM people;
97
+```
98
+Notice the difference in the returned table with the aliases?
99
+
100
+```SQL
101
+SELECT MIN(birthday) FROM people;
102
+```
103
+
104
+#### Strings
105
+
106
+```SQL
107
+SELECT UPPER (first_name), LOWER(last_name) FROM people;
108
+```
109
+
110
+```SQL
111
+SELECT REPLACE(last_name, 'a', '1') FROM people;
112
+```
113
+
114
+```SQL
115
+SELECT last_name FROM people;
116
+```
117
+
118
+```SQL
119
+INSERT INTO people (first_name, last_name, mobile) 
120
+VALUES ('Otto', 'Von Count', '656-6548');
121
+```
122
+
123
+```SQL
124
+SELECT CONCAT(first_name, last_name) FROM people
125
+WHERE last_name = 'Smith';
126
+```
127
+
128
+```SQL
129
+SELECT CONCAT(first_name, ' ', last_name) 
130
+FROM people 
131
+WHERE last_name = 'Smith';
132
+```
133
+
134
+```SQL
135
+SELECT CONCAT_WS(' ',first_name, last_name, mobile) 
136
+FROM people WHERE last_name= 'Smith';
137
+```
138
+
139
+```SQL
140
+SELECT homenumber, LEFT(homenumber, 3), RIGHT(homenumber, 2) FROM homes;
141
+```
142
+
143
+```SQL
144
+SELECT LENGTH(address), CHAR_LENGTH(address) FROM homes;
145
+```
146
+
147
+#### Compare
148
+
149
+```SQL
150
+SELECT first_name, last_name, YEAR(birthday) FROM people WHERE birthday >= '1970-07-06' AND birthday<='1987-07-06';
151
+```
152
+
153
+```SQL
154
+SELECT first_name, birthday FROM people WHERE first_name='Thomas' OR first_name='Raj' OR first_name='Sheeri';
155
+```
156
+
157
+```SQL
158
+SELECT first_name, birthday FROM people WHERE first_name IN ('Noelle', 'Thomas', 'Raj');
159
+```
160
+
161
+#### Wild Cards
162
+
163
+```SQL
164
+SELECT first_name FROM people WHERE RIGHT(first_name,1)='e';
165
+```
166
+
167
+```SQL
168
+SELECT first_name FROM people WHERE first_name LIKE '%j'; 
169
+```
170
+
171
+```SQL
172
+SELECT first_name FROM people WHERE first_name LIKE '%o%';
173
+```
174
+
175
+```SQL
176
+SELECT first_name FROM people WHERE first_name NOT LIKE '%o%';
177
+```
178
+
179
+```SQL
180
+SELECT COUNT(*) FROM people;
181
+```
182

185
+```
186
+
187
+```SQL
188
+SELECT last_name, GROUP_CONCAT(mobile) FROM people GROUP BY last_name;
189
+```
190
+
191
+```SQL
192
+SELECT last_name, GROUP_CONCAT(mobile SEPARATOR ' and ') FROM people GROUP BY last_name;
193
+```
194
+
195
+```SQL
196
+SELECT last_name, GROUP_CONCAT(mobile SEPARATOR ' and ') FROM people GROUP BY last_name  HAVING COUNT(*)>1;
197
+```
198
+
199
+```SQL
200
+SELECT last_name, GROUP_CONCAT(mobile SEPARATOR ' and ') FROM people WHERE last_name != 'Cabral' GROUP BY last_name  HAVING COUNT(*)>1;
201
+```
202
+
203
+#### Sorting 
204
+
205
+```SQL
206
+SELECT first_name, birthday FROM people ORDER BY birthday;
207
+```
208
+
209
+```SQL
210
+SELECT first_name, birthday FROM people ORDER BY birthday DESC;
211
+```
212
+
213
+```SQL
214
+SELECT first_name, last_name FROM people ORDER BY last_name, first_name;
215
+```
216
+
217
+```SQL
218
+SELECT first_name, birthday FROM people ORDER BY birthday DESC LIMIT 3;
219
+```
220
+
221
+```SQL
222
+SELECT first_name, MONTHNAME(birthday) as mon, birthday FROM people ORDER BY MONTH(birthday);
223
+```
224

227
+```
228
+
229
+```SQL
230
+SELECT last_name, COUNT(*) FROM  people GROUP BY last_name ORDER BY NULL;
231
+```
232
+
233
+#### Inserting and Replacing Records
234
+
235
+```SQL
236
+INSERT INTO people (first_name, last_name, birthday, home_id)
237
+VALUES ('John', 'Smith', '1998-04-07', 4),
238
+('Maya', 'Wasserman' , NULL, 4),
239
+('Paul', 'Thompson', '1996-05-27', 1);
240
+```
241
+
242
+#### Deleting
243
+
244
+```SQL
245
+DELETE FROM people WHERE first_name='Maya';
246

+##### Exercise:
289
+
290
+Devise a report:
291
+
292
+Show all the people in your address table, only if you know their birthday.
293
+
294
+Show their name, address and birthday ordered by birthday month, so January birthdays are first.
295
+
296
+Devise a report:
297
+
298
+Output all information for all people and their home information
299

+## Mini Movie Database
302
+
303
+Once you have figured out the correct queries for each step, 
304
+save a copy in a file called `src/main/resources/script.sql`. This will be how you submit this assignment. 
305
+If at any time you need to reset the database, you can restart your Spring Boot server.
306
+
307
+Add the following movies to the `movies` table using an insert statement:
308
+
309
+| Title | Runtime | Genre | IMDB Score | Rating |
310
+| ----- | ------- | ----- | ----------- | ----- |
311
+| Howard the Duck | 110 | Sci-Fi | 4.6 | PG |
312
+| Lavalantula | 83 | Horror | 4.7 | TV-14 |
313
+| Starship Troopers | 129 | Sci-Fi | 7.2 | PG-13 |
314
+| Waltz With Bashir | 90 | Documentary | 8.0 | R |
315
+| Spaceballs | 96 | Comedy | 7.1 | PG |
316
+| Monsters Inc. | 92 | Animation | 8.1 | G |
317
+
318
+Add a few more movies of your choosing.
319
+
320
+Create a query to find all movies in the Sci-Fi genre.
321
+
322
+Create a query to find all films that scored at least a 6.5 on IMDB
323
+
324
+For parents who have young kids, but who don't want to sit through long children's movies, 
325
+create a query to find all of the movies rated G or PG that are less than 100 minutes long.
326
+
327
+Create a query to show the average runtimes of movies scoring below a 7.5 on imdb, grouped by their respective genres.
328
+
329
+There's been a data entry mistake; Starship Troopers is actually rated R, not PG-13. 
330
+Create a query that finds the movie by its title and changes its rating to R.
331
+
332
+Show the ID number and rating of all of the Horror and Documentary movies in the database. Do this in only one query.
333
+
334
+This time let's find the average, maximum, and minimum IMDB score for movies of each rating.
335
+
336
+That last query isn't very informative for ratings that only have 1 entry. 
337
+Use a `HAVING COUNT(*) > 1` clause to only show ratings with multiple movies showing.
338
+
339
+Let's make our movie list more child-friendly. Delete all entries that have a rating of R. 
340
+Remember to record your query in `script.sql`.
