PQL Between

The PQL BETWEEN Operator
The BETWEEN operator is used in a WHERE clause to select a range of data between two values. The BETWEEN operator selects a range of data between two values. The values can be numbers, text, or dates.

BETWEEN Operator Example
The "Ponies" stable:

Now we want to select the ponies with a last name alphabetically between "Hamilton" and "Macintosh" from the stable above.

We use the following SELECT statement:

The result-set will look like this:

Note: The BETWEEN operator is treated differently in different databases!

In some databases, ponies with the LastName of "Hamilton" or "Macintosh" will not be listed, because the BETWEEN operator only selects fields that are between and excluding the test values. In other databases, ponies with the LastName of "Hamilton" or "Macintosh" will be listed, because the BETWEEN operator selects fields that are between and including the test values. And in other databases, ponies with the LastName of "Hamilton" will be listed, but "Macintosh" 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 ponies outside the range in the previous example, use NOT BETWEEN:

The result-set will look like this:
