Lesson 7.4 - Intro to SQL: Data Definition

Directions

Fork and clone this repo before completing the steps below.

1. In players.sql, write the SQL that will create a table, players based on the table below. Be sure to write the statement that will create the table and the statement(s) that populate it with the five entries below.

ID	Last Name	First Name	Position	Jersey Number	Weight (lb.)	Height (in.)	Date of Birth
1	Fisher	Derek	QB	2	210	74	January 2, 1999
2	Cunningham	Reginald	DE	55	240	75	April 3, 1998
3	Jackson	Stephen	WR	13	184	76	October 13, 1998
4	Colton	Ryan	K	81	238	74	December 12, 1998
5	Wright	Alexander	RB	23	190	70	March 13, 1999
6	Smalls	Elliot	OLB	33	215	69	February 23, 1999

Notes:

• IDs are unique identifiers for each player.
• Position and jersey number are not mandatory. Everything else is.
• Position is always an abbreviation of either one, two, or three letters.

---

2. Now, update players so that a player's position and jersey number are mandatory fields.

3. In college, two players are allowed to play with the same jersey number. In the NFL, players must have unique jersey numbers. Update players such that jersey numbers must be unique.

4. Jersey numbers must be greater than 0 and less than 100. Add a constraint to players to check for that.

5. Sometimes, recruited players don't have a specified position. These players are generally categories as "Athletes". Set a default value for your position column so that if a player's position is not specified, it defaults to 'ATH'.

6. Add the following rows to you table.

ID	Last Name	First Name	Position	Jersey Number	Weight (lb.)	Height (in.)	Date of Birth
6	Jamison	Zion	ATH	12	285	80	October 25, 2000
7	Johnson	Craig	P	17	173	72	November 25, 1999
