The BETWEEN Operator
The BETWEEN operator selects a range of data between two values. The values can be numbers, text, or dates.SQL BETWEEN Syntax
SELECT column_name(s) FROM table_name WHERE column_name BETWEEN value1 AND value2 |
BETWEEN Operator Example
The "Persons" table:P_Id | LastName | FirstName | Address | City |
---|---|---|---|---|
1 | Hansen | Ola | Timoteivn 10 | Sandnes |
2 | Svendson | Tove | Borgvn 23 | Sandnes |
3 | Pettersen | Kari | Storgt 20 | Stavanger |
We use the following SELECT statement:
SELECT * FROM Persons WHERE LastName BETWEEN 'Hansen' AND 'Pettersen' |
P_Id | LastName | FirstName | Address | City |
---|---|---|---|---|
1 | Hansen | Ola | Timoteivn 10 | Sandnes |
In some databases, persons with the LastName of "Hansen" or "Pettersen" will not be listed, because the BETWEEN operator only selects fields that are between and excluding the test values.
In other databases, persons with the LastName of "Hansen" or "Pettersen" will be listed, because the BETWEEN operator selects fields that are between and including the test values.
And in other databases, persons with the LastName of "Hansen" will be listed, but "Pettersen" will not be listed (like the example above), because the BETWEEN operator selects fields between the test values, including the first test value and excluding the last test value.
Therefore: Check how your database treats the BETWEEN operator.
Example 2
To display the persons outside the range in the previous example, use NOT BETWEEN:SELECT * FROM Persons WHERE LastName NOT BETWEEN 'Hansen' AND 'Pettersen' |
P_Id | LastName | FirstName | Address | City |
---|---|---|---|---|
2 | Svendson | Tove | Borgvn 23 | Sandnes |
3 | Pettersen | Kari | Storgt 20 | Stavanger |
