Answer:
The scripts are:
1. SELECT * FROM planes
2. UPDATE planes SET YEAR = 2013 WHERE year IS NULL
3. INSERT INTO planes (Tailnum, Year, type, Manufacturer, Model, Engines, Seats) VALUES ('N15501',2013,'Fixed wing single engine', 'BOEING', 'A222-101',3,100,NULL)
4. DELETE FROM planes WHERE Tailnum = 'N15501'
Explanation:
1. SELECT * FROM planes
To select all from a table, use <em>select * from [table-name]. </em>In this case, the table name is planes
2. UPDATE YEAR = 2013 WHERE year IS NULL
To do this, we use the update query which is as follows:
<em>UPDATE [table-name] SET [column-name]= [value] WHERE [column] IS NULL</em>
So: the above query will update all YEAR column whose value is NULL to 2014
3. INSERT INTO planes (Tailnum, Year, type, Manufacturer, Model, Engines, Seats) VALUES ('N15501',2013,'Fixed wing single engine', 'BOEING', 'A222-101',3,100,NULL)
To insert is very straight foward.
The syntax is:
INSERT INTO [table-name] (column names) VALUES (values)
4. DELETE FROM planes WHERE Tailnum = 'N15501'
To do this, we use the update query which is as follows:
<em>DELETE FROM [table-name] WHERE [column] = [value]</em>
So: The above query will delete the entry in (3) above
