[ NOT ] BETWEEN¶

Returns TRUE when the input expression (numeric or string) is within the specified lower and upper boundary.

Syntax¶

<expr> [ NOT ] BETWEEN <lower_bound> AND <upper_bound>

Copy

Usage notes¶

expr BETWEEN lower_bound AND upper_bound is equivalent to expr >= lower_bound AND expr <= upper_bound.
The specified upper boundary must be larger/greater than the lower boundary.

Collation details¶

The expression A BETWEEN X AND Y is equivalent to A >= X AND A <= Y. The collations used for comparing with X and Y are independent and do not need to be identical, but both need to be compatible with the collation of A.

Examples¶

Here are a few simple examples of using BETWEEN with numeric and string values:

SELECT 'true' WHERE 1 BETWEEN 0 AND 10;

Copy

+--------+
| 'TRUE' |
|--------|
| true   |
+--------+

SELECT 'true' WHERE 1.35 BETWEEN 1 AND 2;

Copy

+--------+
| 'TRUE' |
|--------|
| true   |
+--------+

SELECT 'true' WHERE 'the' BETWEEN 'that' AND 'then';

Copy

+--------+
| 'TRUE' |
|--------|
| true   |
+--------+

The following examples use COLLATE with BETWEEN:

SELECT 'm' BETWEEN COLLATE('A', 'lower') AND COLLATE('Z', 'lower');

Copy

+-------------------------------------------------------------+
| 'M' BETWEEN COLLATE('A', 'LOWER') AND COLLATE('Z', 'LOWER') |
|-------------------------------------------------------------|
| True                                                        |
+-------------------------------------------------------------+

SELECT COLLATE('m', 'upper') BETWEEN 'A' AND 'Z';

Copy

+-------------------------------------------+
| COLLATE('M', 'UPPER') BETWEEN 'A' AND 'Z' |
|-------------------------------------------|
| True                                      |
+-------------------------------------------+
