[轉貼]Oracle / PLSQL: BETWEEN Condition

Oracle / PLSQL: BETWEEN Condition

This Oracle tutorial explains how to use the Oracle BETWEEN condition with syntax and examples.

Description

The Oracle BETWEEN condition is used to retrieve values within a range in a SELECT, INSERT, UPDATE, or DELETE statement.

Syntax

The syntax for the BETWEEN condition in Oracle/PLSQL is:

expression BETWEEN value1 AND value2;

Parameters or Arguments

expression
A column or calculation.
value1 and value2
Two values that create an inclusive range that expression is compared to.

Note


  • The Oracle BETWEEN condition will return the records where expression is within the range of value1 and value2 (inclusive).

Example - With Numeric

Let's look at some Oracle BETWEEN condition examples using numeric values. The following numeric example uses the BETWEEN condition to retrieve values within a numeric range.

For example:


SELECT *
FROM customers
WHERE customer_id BETWEEN 4000 AND 4999;

This Oracle BETWEEN example would return all rows from the customers table where the customer_id is between 4000 and 4999 (inclusive). It is equivalent to the following SELECT statement:


SELECT *
FROM customers
WHERE customer_id >= 4000
AND customer_id <= 4999;

Example - With Date

Next, let's look at how you would use the Oracle BETWEEN condition with Dates. The following date example uses the BETWEEN condition to retrieve values within a date range.

For example:


SELECT *
FROM order_details
WHERE order_date BETWEEN TO_DATE ('2014/02/01', 'yyyy/mm/dd')
AND TO_DATE ('2014/02/28', 'yyyy/mm/dd');

This Oracle BETWEEN condition example would return all records from the order_details table where the order_date is between Feb 1, 2014 and Feb 28, 2014 (inclusive). It would be equivalent to the following SELECT statement:


SELECT *
FROM order_details
WHERE order_date >= TO_DATE('2014/02/01', 'yyyy/mm/dd')
AND order_date <= TO_DATE('2014/02/28','yyyy/mm/dd');

Example - Using NOT Operator

The Oracle BETWEEN condition can also be combined with the Oracle NOT operator. Here is an example of how you would combine the BETWEEN condition with the NOT Operator.

For example:


SELECT *
FROM customers
WHERE customer_id NOT BETWEEN 3000 AND 3500;

This Oracle BETWEEN example would return all rows from the customers table where the customer_id was NOT between 3000 and 3500, inclusive. It would be equivalent to the following SELECT statement:


SELECT *
FROM customers
WHERE customer_id < 3000
OR customer_id > 3500;
