Chapter 3 Structured Query Language

1) The result for SELECT statements in SQL is a relation unless the result is a single number.

2) To force the DBMS to remove duplicate rows from the results of an SQL SELECT query, the

keyword DISTINCT must be used.

3) In SQL, the WHERE clause is used to specify which columns will be included in the result.

4) In SQL, multiple conditions in the WHERE clause can be combined by using the SQL AND

keyword.

5) In SQL, to refer to a range of values in a WHERE clause, use the WITHIN keyword.

6) In SQL, the NOT keyword can be combined with the IN keyword to form the NOT IN

condition for selecting values.

7) In SQL, the LIKE keyword can be used to select on partial values.

8) In SQL, the LIKE keyword can be combined with the NOT keyword to form the NOT LIKE

condition for selecting values.

9) In SQL, the IS NULL keyword can be used to select on records containing NULL values in a

particular column.

10) In SQL, the order of the rows that result from a SELECT statement can be set using the

SORT BY phrase.

40) The SQL command used to add new data to a table is ________.

42) When using SQL to create a table, a column is defined by declaring, in this order: data type,

column name, and optional constraints.
