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:

oracle asm指的是“自动存储管理”,是一种卷管理器,可自动管理磁盘组并提供有效的数据冗余功能;它是做为单独的Oracle实例实施和部署。asm的优势:1、配置简单、可最大化推动数据库合并的存储资源利用;2、支持BIGFILE文件等。

方法:1、利用“select*from user_indexes where table_name=表名”语句查询表中索引;2、利用“select*from all_indexes where table_name=表名”语句查询所有索引。

在Oracle中,可利用lsnrctl命令查询端口号,该命令是Oracle的监听命令;在启动、关闭或重启oracle监听器之前可使用该命令检查oracle监听器的状态,语法为“lsnrctl status”,结果PORT后的内容就是端口号。

在oracle中,可以利用“TO_SINGLE_BYTE(String)”将全角转换为半角;“TO_SINGLE_BYTE”函数可以将参数中所有多字节字符都替换为等价的单字节字符,只有当数据库字符集同时包含多字节和单字节字符的时候有效。

在oracle中,可以利用“drop sequence sequence名”来删除sequence;sequence是自动增加数字序列的意思,也就是序列号,序列号自动增加不能重置,因此需要利用drop sequence语句来删除序列。

在oracle中,可以利用“select ... From all_tab_columns where table_name=upper('表名') AND owner=upper('数据库登录用户名');”语句查询数据库表的数据类型。

方法:1、利用“LOWER(字段值)”将字段转为小写,或者利用“UPPER(字段值)”将字段转为大写;2、利用“REGEXP_LIKE(字符串,正则表达式,'i')”,当参数设置为“i”时,说明进行匹配不区分大小写。

方法:1、利用“alter system set sessions=修改后的数值 scope=spfile”语句修改session参数;2、修改参数之后利用“shutdown immediate – startup”语句重启服务器即可生效。
