How to write a value that is not equal to a certain value in Oracle

In Oracle, you can use the "NOT" operator to indicate that it is not equal to a certain value. The specific syntax is as follows:

column_name <> value

Among them:

• column_name is the column name to be compared
• value is the column name to be compared Comparative values

Example:

Suppose there is a table named "employees", which contains "emp_id" and "salary" columns. To query for employees whose salary is not equal to $1000, you can use the following query:

SELECT emp_id, salary
FROM employees
WHERE salary <> 1000;

This query will return all rows with emp_id and salary columns where the salary column is not equal to $1000.
