In Oracle, the NOT EQUAL operator, represented by the != symbol, is used to compare two expressions and return TRUE if they are not equal, and FALSE if they are equal. This operator is commonly used in SQL queries to filter rows based on specific criteria or to perform data validation.
The NOT EQUAL operator is an essential tool for data manipulation and analysis in Oracle. It allows users to create precise queries and ensure data integrity by excluding unwanted or incorrect data from their results. Additionally, it plays a crucial role in data validation processes, helping to identify and handle inconsistencies or errors within a dataset.
