Arlecino [84]

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 select * from [table-name]. In this case, the table name is planes

2. UPDATE $planes\ SET$ YEAR = 2013 WHERE year IS NULL

To do this, we use the update query which is as follows:

UPDATE [table-name] SET [column-name]= [value] WHERE [column] IS NULL

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:

DELETE FROM [table-name] WHERE [column] = [value]

So: The above query will delete the entry in (3) above

In the past few years, it used to be a difficult process to collect, extract and analyze data. These days, however, the development of business intelligence software allows anyone without a heavy IT background to produce reports that will later need to be analyzed, thus accelerating the decision process.
