SQL Between: Where To Use SQL Between Operator

Overview: SQL Between

In most of the widely used database systems, the SQL between or the Oracle Connection object and Oracle Server could be easily accessed. The data conversion is done automatically by the application and the stored procedures or the views are automatically updated in the Oracle database. The user does not need to know the SQL between or the Oracle connection objects to convert the data from one server to another server. These two data types could be easily converted with the help of the Oracle database. The SQL BETWEEN Operator is one of the most common and simple functions in the database management systems.

Oracle provides the capability to the developer to convert the two data types into any other data types. The developer can use the DML or the Designer Meta Engine to create the two data types or he can create the relationship among them. He can also use the stored procedures or the views to update the two data. The developer can select any of the methods to update the two data to the target application or the server side application.

The SQL BETWEEN Operator works on the two data types as an expression. The first is the text operator and the second is the value operator. The SQL Server BETWEEN operator can be used to convert the data from one database or source to another. The text operator is also known as the LIKE operator. The SQL Server BETWEEN operator can be used for any type of table, coordinate or value so that it can be accessed on the application.

The general syntax is

SELECT column-names
  FROM table-name
 WHERE column-name BETWEEN value1 AND value2

The SQL Server BETWEEN operator works on the two data types as an expression. The first is the text operator and the second is the value operator. The SQL BETWEEN operator can be used to convert the data from one database or source to another. The text operator can be used for any type of table, coordinate or value so that it can be accessed on the application. The value operator on the other hand is used to compare two values of different types.

BETWEEN SQL Examples(WHERE)

The result obtained by the BETWEEN operator when it is applied on the two data will be the logical comparison results. This means that the output will be logical and a logical comparison is required. The SQL Server BETWEEN operator can be used in order to determine the difference between two rows or columns. The result obtained will be of type int. The use of this function is required when you need to compare two columns that are not the same.

Problem

List all employee whose age between 30 and 40.

• Consider following table

Solution

SELECT * FROM Emp_table WHERE Emp_Age BETWEEN 30 AND 40
 ORDER BY Emp_ID

NOT BETWEEN Example

Problem

List all employee whose age not between 30 and 40.

• Consider following table

Solution

SELECT * FROM Emp_table WHERE Emp_Age Not BETWEEN 30 AND 40
 ORDER BY Emp_ID

In above query we have used SQL Between to get desired output. BETWEEN/WHERE returns values that fall within a given range. This clause is a equivalent to >= AND <=. The BETWEEN operator is inclusive, that is, begin and end values are included.

Where to use SQL Between

There are times when a company requires the use of a SQL Server feature such as BETWEEN. This can be used for data validation, so that the results of the comparison can be trusted. The SQL Server BETWEEN operator can also be used to determine the equality or the inequality of two types or values so that the data can be inserted into the correct database. The best thing about the usage of SQL BETWEEN is that the application can save significant amount of time.

A company does not have to call the developer in order to create the BETWise table or a Bwt_row expression. This is because the developer can create these databases. With the availability of Bwt_row, an application can easily create the SQL between a known range of data. The developer just has to pass the query that contains the range of data that he requires.

The use of SQL between is beneficial in many ways. The primary benefit of the BETWise relation is that there is no need for any programming of complex statement. The Bwt_row expression can be called directly, so that the developer does not have to create or maintain any database. The developer has better control over the result that he is getting. The SQL between can help in making the task of logical comparisons easier.
