Question

What role does inventory play? select bookid, boooktitle, bookauthor, quantityonhand from ____;

a) The WHERE clause
b) The FROM clause
c) The ORDER BY clause
d) The GROUP BY clause

Answer 1

The answer is b) the FROM clause, where the name of the table 'inventory' should be placed in an SQL query to define the source of the data.

Step-by-step explanation:

In SQL, the inventory table is not a clause but the possible name of our data source that we need to specify in the FROM clause of the query. The example query selects the columns 'bookid,' 'boooktitle,' 'bookauthor,' and 'quantity-on-hand' from a source table that should be specified after the FROM keyword. Therefore, the answer is b) the FROM clause.

The FROM clause is crucial in an SQL query as it defines the source of the data to be retrieved. Without specifying the correct table in the FROM clause, the database will not know from where to select the specified columns. The WHERE clause is used for filtering records based on certain conditions, the ORDER BY clause is used to sort results, and the GROUP BY clause is used to group rows that have the same values in specified columns into aggregate data.
