This article is to share with you about the use of between in sql. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

In sql, the BETWEEN operator is used to select values within the data range between two values. Where "between and" includes boundary values, that is, both ends; "not between" does not include boundary values.

SQL BETWEEN operator

The BETWEEN operator selects values within the data range between two values. These values can be numeric, text, or date.

The BETWEEN operator is often used in conjunction with AND as a WHERE condition for query result sets.

SQL BETWEEN syntax

SELECT column_name (s) FROM table_nameWHERE column_name BETWEEN value1 AND value2

Example:

Data sheet

+-- + | id | name | url | alexa | country | +-+-- -+ | 1 | Google | https://www.google.cm/ | 1 | USA | | 2 | Taobao | https://www.taobao.com/ | 13 | CN | | 3 | | http://www.php.cn/ | 4689 | CN | 4 | Weibo | http://weibo.com/ | 20 | CN | | 5 | Facebook | https://www.facebook.com/ | 3 | USA | | 7 | stackoverflow | http://stackoverflow.com/ | 0 | IND | +-+ -- +
