You can also use mathematical operators (, ) in case you want to compare two numerical columns.

We will look at different use cases to compare two columns in MySQL In this article, we will look at how to compare two columns in MySQL. MySQL allows you to easily compare two columns using operators as well as nested queries. Now, you’re ready to get started with using LIKE in SQL and BETWEEN in SQL for comparing the values in your database.Sometimes you may need to compare two columns from same table or different table, in MySQL. Well, this brings us to the end of this tutorial section. Once the query is executed, the table appears. Select * From employee where e_salary BETWEEN 600000 Īfter writing the query, click on the execute button to check for errors. Let’s display the salaries of employees between $60,000 and $120,000 from the employee table.

Select * From employee where e_age BETWEEN 25 AND 35 Let’s, now, display employees aged between 25 and 35 from the above employee table. Where SELECT, FROM, WHERE, BETWEEN, and AND are the keywords, column_list is a list of columns, tablename is the name of the table, column_N is the column name, val1 is the minimum value of the range, and val2 is the maximum value of the range, followed by a semicolon. For example, to extract only those records where the age of the person is between 20 and 25, we have to use the BETWEEN query in SQL. The BETWEEN operator in SQL is used to select values within a given range. Select * from employee where e_age LIKE '2_' Now, let’s take another example in which we extract all records from the database where the employee age is in the twenties. As we can see in the result, we got only two rows in which the names start with the letter “j”. Once the SQL query is executed, a message appears like “ Commands completed successfully”. ![]() Extract all records where the employee name starts with the letter ‘J’ Select * from employee where e_name LIKE 'j%' Īfter writing the query, click on the execute button to check for errors. Let’s do some operations with the LIKE query in SQL. Let us take an example to understand this better, imagine that we want to extract a person’s name from the employee table below. ![]() Where SELECT, FROM, WHERE, and LIKE are the keywords, column_list is the list of columns, tablename is the name of the table, column_N is the column name, and there is a pattern followed by a semicolon. Here are the examples of how we use the LIKE operator using wildcard Like Operatorįinds values that have “en” at any positionįinds values that have “e” only in the second positionįinds values that start with “e” and are at least 3 characters in lengthįinds values that start with “e” and end with “0” Interested in learning SQL?
