What is the usage of oracle between
between is used to select row data with values within a range, the syntax is "SELECT field name FROM table name WHERE expression [NOT] BETWEEN lower limit AND upper limit"; when this keyword is formed for the rows returned by the SELECT statement When searching for a condition, only rows whose values fall within the specified range are returned.
The operating environment of this tutorial: Windows 7 system, Oracle 11g version, Dell G3 computer.
The BETWEEN operator can be used to select row data with values within a range in Oracle.
Oracle BETWEEN Operator Syntax
The BETWEEN operator allows you to specify a range to test. When you use the BETWEEN operator to form search conditions for the rows returned by a SELECT statement, only rows whose values fall within the specified range are returned.
The following explains the syntax of the BETWEEN operator:
expression [ NOT ] BETWEEN low AND high
In the above syntax:
low and high - low and hight specify what is to be tested The lower and upper limits of the range. The low and hight values can be literals or expressions.
expression - is an expression tested within the range defined by low and hight. To be able to compare, the data types of expression, low, and hight must be the same.
AND - The AND operator acts as a placeholder to separate low and high values.
If the value of expression (expression) is greater than or equal to the value of low and less than or equal to the value of hight, the BETWEEN operator returns true.
value >= low AND value <= high
NOT BETWEEN operator negates the result of BETWEEN operator.
Oracle BETWEEN Example
Let’s take a look at some examples of using the Oracle BETWEEN operator.
1. Oracle BETWEEN numerical example
Take the products table below as an example:
The following statement returns All products with a standard cost between 500 and 600:
SELECT
product_name,
standard_cost
FROM
products
WHERE
standard_cost BETWEEN 500 AND 600
ORDER BY
standard_cost;In this example, we compare and filter the range of values in the standard cost (standard_cost) column between 500 and 600. This query only returns products whose standard cost is between the following ranges:
To query for products whose standard cost is not between 500 and 600, replace the NOT operator as follows Add to the above query:
SELECT
product_name,
standard_cost
FROM
products
WHERE
standard_cost NOT BETWEEN 500 AND 600
ORDER BY
product_name;2. Oracle BETWEEN date example
Take the orders table below as an example to demonstrate:
To query customer orders from December 1, 2016 to December 31, 2016, you can use the following statement:
SELECT
order_id, customer_id, status, order_date
FROM
orders
WHERE
order_date BETWEEN DATE '2016-12-01' AND DATE '2016-12-31'
ORDER BY
order_date;After executing the statement, you can get the following results:

What to learn Java? A summary of Java learning routes and essential knowledge points
May 20, 2025 pm 08:15 PM
Learning Java requires learning basic syntax, object-oriented programming, collection frameworks, exception handling, multithreading, I/O streaming, JDBC, network programming, and advanced features such as reflection and annotation. 1. The basic syntax includes variables, data types, operators and control flow statements. 2. Object-oriented programming covers classes, objects, inheritance, polymorphism, encapsulation and abstraction. 3. The collection framework involves ArrayList, LinkedList, HashSet, and HashMap. 4. Exception handling ensures program robustness through try-catch block. 5. Multithreaded programming requires understanding of thread life cycle and synchronization. 6. I/O streams are used for data reading, writing and file operations. 7. JDBC is used to interact with databases. 8. Network programming passes S
Connection and data visualization of Oracle databases with BI tools such as Tableau
May 19, 2025 pm 06:27 PM
To connect Oracle database to Tableau for data visualization, you need to follow the following steps: 1. Configure Oracle database connection in Tableau, use ODBC or JDBC drivers; 2. Explore data and create visualizations, such as bar charts, etc.; 3. Optimize SQL queries and indexes to improve performance; 4. Use Oracle's complex data types and functions to implement through custom SQL queries; 5. Create materialized views to improve query speed; 6. Use Tableau's interactive functions such as dashboard for in-depth analysis.
How to connect to oracle database connection pool using jdbc
Jun 04, 2025 pm 10:15 PM
The steps to connect to an Oracle database connection pool using JDBC include: 1) Configure the connection pool, 2) Get the connection from the connection pool, 3) Perform SQL operations, and 4) Close the resources. Use OracleUCP to effectively manage connections and improve performance.
Using Oracle Database Integration with Hadoop in Big Data Environment
Jun 04, 2025 pm 10:24 PM
The main reason for integrating Oracle databases with Hadoop is to leverage Oracle's powerful data management and transaction processing capabilities, as well as Hadoop's large-scale data storage and analysis capabilities. The integration methods include: 1. Export data from OracleBigDataConnector to Hadoop; 2. Use ApacheSqoop for data transmission; 3. Read Hadoop data directly through Oracle's external table function; 4. Use OracleGoldenGate to achieve data synchronization.
Parallel query configuration and performance improvements in Oracle databases
May 19, 2025 pm 06:24 PM
In Oracle database, the steps to configure parallel query to improve performance include: 1. Set at the database level, and implement it by modifying initialization parameters such as PARALLEL_DEGREE_POLICY and PARALLEL_MAX_SERVERS; 2. Set at the session level, adjust the parallelism of the current session through the ALTERSESSION command; 3. Consider key points such as parallelism, resource management and data distribution; 4. Improve performance by optimizing query planning, adjusting parallelism and monitoring and tuning. These steps help to take full advantage of parallel queries and significantly improve the query performance of the database.
How to query your administrator password for oracle database
Jun 04, 2025 pm 10:06 PM
Directly querying administrator passwords is not recommended in terms of security. The security design principle of Oracle database is to avoid storing passwords in plain text. Alternative methods include: 1. Reset the SYS or SYSTEM user password using SQL*Plus; 2. Verify the encrypted password through the DBMS_CRYPTO package.
How to do oracle without taking a certain field value
Jun 04, 2025 pm 10:21 PM
In Oracle database, if you want to not return the value of a certain field when querying, you can use the following three methods: Only list the required fields in the SELECT statement and do not select the unwanted fields. Create views to simplify queries, but pay attention to the complexity and maintenance costs of the views. Excluding unwanted columns using subqueries or JOINs is suitable for dynamic exclusion of columns, but may affect query performance. Each method has its applicable scenarios and potential disadvantages, and the most suitable method needs to be selected based on specific needs and performance considerations.
