Description: The ‘WHERE’ clause is a fundamental part of the Structured Query Language (SQL) used to specify conditions that must be met to filter records in a query. This clause allows users to select only those data that meet specific criteria, resulting in a more manageable and relevant set of results. ‘WHERE’ can be used in various SQL operations, such as SELECT, UPDATE, and DELETE, and is essential for effective database manipulation. By applying conditions in the ‘WHERE’ clause, users can utilize logical and comparison operators such as ‘=’, ‘>’, ‘<', 'AND', 'OR', and 'NOT', providing great flexibility in formulating queries. The ability to filter data accurately is crucial in data analysis, as it allows analysts and developers to obtain specific information without having to process large volumes of irrelevant data. In summary, the 'WHERE' clause is a powerful tool that enhances the efficiency and effectiveness of SQL queries, enabling users to work more intelligently with the information stored in relational databases.
